Chapter 4 - Options for reform


________________________



4.1 As noted in the preface to this report, the consultation paper issued in November 1998 was prompted by concerns that the existing procedure for determining the admissibility of confession statements in criminal proceedings was deficient, in particular because of the time and resources consumed by the voir dire. The consultation paper set out the arguments for and against change and concluded by presenting three options for reform of the procedure currently adopted. We will return to these three options later, but begin by briefly re-stating the main arguments set out in the consultation paper for and against reform, referring in the course of that discussion to the views expressed by those who responded to the consultation paper.


Arguments in favour of reform


Duplication of evidence


4.2 The principal argument in favour of finding alternatives to the voir dire is that to do so would eliminate the duplication of evidence which the existing system necessitates, with a consequent saving in court time and costs. Not infrequently the same evidence which is relevant to the issue of admissibility is also relevant to weight or credibility and time would be saved by taking the evidence in the presence of the jury. Under the alternative procedure, for instance, the same issue need not be tried twice, once before the judge sitting alone, and later in the jury’s presence. The duplication of evidence which is involved in a voir dire also provides the witnesses with an opportunity to change their evidence in the main trial after they have seen how they were cross-examined in the voir dire, with no opportunity for the jury to test the two versions, since they will hear only the second.

4.3 In response, it was pointed out by a number of those who responded to the consultation paper that it was misleading to refer to the same issue being tried twice as there were in fact two different issues to be dealt with: the admissibility of the confession statement was a matter for the judge, while the reliability of the witnesses and of the statement itself were matters for the jury.

4.4 It was further argued that the administrative advantage of reducing court time and costs should not be achieved at the expense of jeopardising the accused person’s right to a fair trial. Under the present voir dire procedure where the issue of voluntariness is dealt with in the absence of the jury, the accused can testify freely on the special issue of voluntariness without fear that that evidence would adversely affect the later determination of his guilt by the jury. The presence of the jury in the proceedings determining the issue of voluntariness would deprive the accused of his right to testify freely. In an extreme case, he might choose not to challenge the admissibility of the confession statement for fear of the consequences. As JUSTICE observed,[56]saving court time is only a means to an end. It must not be elevated to become an end in itself.

4.5 One respondent suggested to us that if the end is cost saving, section 17 of the Costs in Criminal Cases Ordinance (Cap. 492) can be used to deal with any unnecessary time wasted on voir dires. Section 17 provides that:

“Where at any time in the course of criminal proceedings a court or a judge is satisfied that costs have been incurred in respect of the proceedings by a party to the proceedings as a result of an unnecessary or improper act or omission by or on behalf of the other party to the proceedings, the court or the judge may, after hearing all such parties, order that all or part of the costs so incurred shall be paid to the first mentioned party to the proceedings by the other party to the proceedings.”


Danger of unfounded prejudice


4.6 The consultation paper pointed out that where evidence is excluded after a voir dire, the jury are left not knowing just what it was, and it may not have been as bad as they imagine. It would therefore be better to let the jury hear all the evidence, and allow the judge to direct the jury to disregard any evidence which is subsequently ruled inadmissible, rather than to run the risk that the jury are influenced by speculative doubts as to the nature of the evidence which was denied them.

4.7 The Bar disagrees with this argument on the basis that once a confession is ruled inadmissible the jury would not be told of its existence. As the jury are generally empanelled subsequent to the hearing of the voir dire, they would not be aware of the fact that there had been a challenge to the admissibility of the statement.


Illogical to assume jury cannot disregard confessions ruled inadmissible


4.8 If a preliminary challenge to a confession is unsuccessful in Hong Kong, it can be repeated before a jury. The jury are not aware, when it is challenged before them, that the judge has already ruled it to be admissible. They are directed in terms that if they conclude that allegations of fabrication of evidence or impropriety are true, or might be true, they should place no weight upon the confession. They thus see the confession, and are treated as being capable of disregarding it if they conclude it is, or might be, the product of malpractice. To that extent, therefore, it is clear that as matters currently stand juries do see confessions which it may be incumbent upon them in the course of their deliberations to set at naught.

4.9 The jury would invariably be directed in terms such as:

“The question is whether you are sure that the accused made a true confession. If you are not, then ignore the alleged confession. If you are sure that the accused made it, then you are concerned with the truth of the confession. You should look at all the circumstances in which it was made. Any pressure on an accused to make a confession lessens the reliability of any confession he makes.”

4.10 The consultation paper suggested that it was but a small step for juries to hear evidence relating to admissibility as well as weight: if they are treated as being capable of disregarding an improperly obtained confession when they retire at the conclusion of the trial, they ought equally to be capable of putting out of their minds a confession statement which comes before them on a hearing as to admissibility, but is then ruled by the judge to be inadmissible in law.

4.11 The Complaints Against Police Office (CAPO) is among those who agree with this view. CAPO considers[57] that as people in Hong Kong are becoming more knowledgeable and better educated, the jury are, as arbiters of the credibility of the evidence laid before them, in general capable of putting out of their minds evidence arising from an inadmissible confession.

4.12 The majority of those who commented on the consultation paper, however, take an opposing view and believe that juries would be prejudiced by evidence relevant to a confession that is later ruled inadmissible by the trial judge. These respondents argue that the present voir dire procedure ensures that lay jurors are not asked to put out of their minds the highly prejudicial evidence arising from a confession statement which is subsequently ruled inadmissible. Instead, the decision is left to a judge, who is professionally trained to separate inadmissible evidence from other admissible evidence when he comes to decide on the guilt or otherwise of an accused. The difficulty for a lay juror to disregard evidence of an inadmissible confession would be particularly acute where the statement is ruled inadmissible mainly on technical grounds.

4.13 It was further suggested to us that even if the jury were able to cast from their minds the inadmissible evidence, there would always be a lurking suspicion that the jury had considered matters which were not allowed to form part of the prosecution’s case. Some respondents saw a double hazard in allowing the jury’s presence in the voir dire proceedings: the danger that the jury would be prejudiced by inadmissible evidence and the impossibility of ascertaining whether or not the jury had been so prejudiced. In addition, the Legal Aid Department referred to the possibility that the jury might interpret a ruling that a confession statement is admissible as an indication that one or more prosecution witnesses are worthier of belief than those called by the defence. That could prove prejudicial to the accused when the general issue of guilt is tried before the same jury.

4.14 To the assertion that jurors should be able to disregard the evidence of an inadmissible confession since they are already expected (on appropriate direction from the trial judge) to set aside other irrelevant and inadmissible testimony which does on occasion go before the jury, barrister Stuart Cotsen remarks[58]:

“[t]here is a real risk that a jury hearing of an accused’s previous convictions will not be capable upon direction of disregarding it. The same for evidence that he was a ‘target’ of the police. These are well established and there are many more examples. How can it then be argued that a jury is capable of disregarding a confession and there is no risk of placing a confession later ruled inadmissible before it?”


The voir dire usurps the jury’s function as arbiters of credibility


4.15 The consultation paper pointed out that the jury, not the judge, decide what credibility and weight to attach to the evidence led before them at a criminal trial. The voir dire procedure, however, excludes the jury from assessing the credibility of the evidence led in relation to the voluntariness of the confession statement. It could be argued that it runs counter to the general principle of criminal trial procedure to leave the assessment of the credibility of the witnesses in relation to this one issue a matter for the judge, rather than the jury.

4.16 The Bar, among others, responded that the existing practice of entrusting judges alone to rule on the issue of admissibility is based on sound policy considerations. The Bar points out that the admissibility of a confession is a question of law, and not a question of fact for the jury, and there is therefore nothing to substantiate the claim that the voir dire procedure has usurped the jury’s function as arbiters of credibility. Once a confession is “ruled in“ by the judge, the jury will have the opportunity to assess the credibility of the witnesses. To that extent, the jury remain the sole arbiters of credibility in respect of a confession which has been ruled admissible by the judge.


Possible negative effect on the jury of exclusion


4.17 Reference was made in the consultation paper to the Australian Law Reform Commission’s Interim Report on Evidence which listed a number of considerations suggesting that the jury need not or should not always be sent out during the hearing of admissibility of confessions.[59] It was suggested that the jury’s attitude to the court and the parties might be adversely affected if the jury is repeatedly excluded from what are apparently important decisions.

4.18 Those who disagreed with this view pointed out that since the admissibility of a confession statement is generally dealt with before the commencement of the trial proper, there is little basis for this concern.


Arguments in favour of continued use of the voir dire


Avoids potential prejudice to the accused


4.19 The main argument in favour of retention of the existing procedure in jury trials is that it avoids the risk that the jury may be prejudiced by hearing evidence about a confession which is subsequently ruled inadmissible by the trial judge. While the professional judge is able to remove consideration of that inadmissible evidence from his mind when reaching a verdict, members of the jury may find it harder to do so and inadmissible evidence which is prejudicial to the accused may colour their judgment. This view was strongly supported by a significant number of those who responded to the consultation paper, including both the Law Society and the Bar.

4.20 The Bar referred to the Privy Council decision in Wong Kam Ming v R to support the assertion that the judiciary must be accorded some means of excluding confessions obtained by improper means. Lord Hailsham in Wong Kam Ming held that:

“Any civilised system of criminal jurisprudence must accord to the judiciary some means of excluding confessions or admissions obtained by improper methods. This is not only because of the potential unreliability of each statement, but also, and perhaps mainly, because in a civilised society it is vital that persons in custody or charged with offences should not be subjected to ill treatment or improper pressure in order to extract confessions. It is therefore of very great importance that the courts should continue to insist that before extra-judicial statements can be admitted in evidence the prosecution must be made to prove beyond reasonable doubt that the statement was not obtained in a manner which should be reprobated and was therefore in the truest sense voluntary.”[60]

4.21 The Law Society expressed concern at the possibility of prejudice if the jury were to hear evidence of a confession which was subsequently ruled inadmissible and argued that the jury should not be expected to engage in the “gymnastics” required to exclude from their minds allegations which they have already heard.


Avoids effective dilution of the right to silence


4.22 The consultation paper pointed out that there may be a situation where an accused wishes to give evidence on the admissibility issue but elects to remain silent on the case proper. The jury might form an adverse view of the accused in such circumstances. That, in turn, may make the accused reluctant to testify on the limited issue for fear of alienating the jury. Lord Fraser expressed the concern in R v Brophy:

“It is of the first importance for the administration of justice that an accused person should feel completely free to give evidence at the voir dire of any improper methods by which a confession or admission has been extracted from him, for he can almost never make an effective challenge of its admissibility without giving evidence himself. He is thus virtually compelled to give evidence at the voir dire, and if his evidence were admissible at the substantive trial, the result might be a significant impairment of his so-called ‘right to silence’ at the trial.”[61]

4.23 The Law Society, among others, supported this view and argued that the accused should not give evidence at the voir dire with the residual fear that his testimony would adversely affect the jury’s impression of him when they are to arrive at a verdict. Equally, the accused should be able to testify in the voir dire without being compelled by circumstances to testify in the main trial for the sole purpose of changing the jury’s adverse impression of him as a result of his testimony in the voir dire. Those consequences would effectively impair the accused’s right to silence at trial.


Options other than the abolition of the voir dire may achieve the same end


4.24 The consultation paper pointed out that if the principal objective was to save court time, the videotaping of confessions might provide a less controversial option. The consultation paper observed that the practice by the Police and the ICAC of videotaping confessions has reduced significantly the number of challenges to the admissibility of confessions. While the heavy resources needed mean that it would be impractical to videotape all police interviews of suspects, it is probable that this will eventually occur in relation to serious cases which are likely to be heard in the District Court or the Court of First Instance of the High Court.

4.25 Even if all interviews were videotaped, it is clear from the data provided by the Police and ICAC that there would still be challenges to admissibility, which would (under current practice) necessitate a voir dire. In relation to the ICAC figures for 1997 quoted in the consultation paper, for instance, 18.2% of cases going to trial involved a voir dire. The grounds for challenge ranged from “oppressive and leading questions” to “defendant was suffering from skin disease and was refused medication”. In addition, even where the videotaped interview is scrupulously conducted, there remains scope for challenge by the accused of conduct before the formal interview began which would negate the voluntary nature of the taped interview. While the wider use of videotape would be expected to reduce the number of challenges to the admissibility of confession statements, that does not justify the abolition of the voir dire. As the Legal Aid Department says[62]:

“That from now on all cautioned statements of defendants are to be video recorded is no justification to abolish the voir dire proceedings altogether. A defendant’s allegations of malpractice are likely to continue to be made, in respect of improprieties which may have taken place before the video recording began.”


The options for reform


4.26 The consultation paper sought the community’s views on the following three options for reform:

Option A: granting the court a discretion to direct that the question of admissibility be dealt with in the presence of the jury;

Option B: making the determination of the issue of admissibility of confession statements a matter for the jury in all cases; and

Option C: granting the court a discretion to direct that the question of admissibility be dealt with in the presence of the jury, coupled with a lowering of the standard of proof for determining voluntariness to that of civil proceedings.

4.27 Written responses were received to the consultation paper from around 50 individuals and organisations. The latter included bodies such as the Law Society, the Bar Association, JUSTICE and the Hong Kong Human Rights Monitor, as well as Government departments including the Police, Customs and Excise and Legal Aid. In addition, comments were elicited on the consultation paper from the Legislative Council’s Panel on Administration of Justice and Legal Services, from members of the Fight Crime Committee and from participants at a forum organised by the Faculty of Law of the Hong Kong University. It is fair to say that the majority of those who responded were against each of the three options for reform proposed. The general arguments in favour of the status quo have been outlined in the preceding paragraphs. We now examine each of the consultation paper’s options in turn in the light of the responses to the consultation paper.


Option A - Granting the court a discretion to direct that the question of admissibility be dealt with in the presence of the jury


4.28 The principal concern which prompted our consideration of the procedure for determining the admissibility of confession statements was the considerable amount of court time which has to be spent in dealing with objections to the admissibility of confession statements. The view was expressed that it is unsatisfactory to have the question of admissibility of a confession considered separately from its evidential weight and effect, particularly so in jury trials. Much time is spent by the judge sitting alone hearing the witnesses in a voir dire to determine admissibility, only to have the witnesses called all over again before the jury to consider the question of evidential weight and effect once the statement is admitted. This is avoided in the magistrates' courts and the District Court by the magistrates or the judge adopting the “alternative procedure” which enables them to disregard the statement as proof of guilt should they at the end of the day determine that voluntariness has not been established.

4.29 The consultation paper suggested that there is no reason why a similar procedure should not be adopted in jury trials. Under such a proposal, at the end of the prosecution case, the defendant can, if he so chooses, elect to testify solely on the issue of admissibility of an alleged confession, or he can elect to testify generally, or not at all. Should the judge at any stage of the trial rule that the statement is inadmissible, he would simply direct the jury to disregard it in their deliberations, and ensure that any written statements previously adduced in evidence by the prosecution are withdrawn.

4.30 Option A proposed that the trial judge should be given a discretion in the interests of justice to order the adoption of the alternative procedure in a jury trial. Such a discretion would give a free hand to the trial judge, who would not be bound to adopt the alternative procedure. If, for example, the prosecution case is weak without the disputed statements, and the evidence bearing on admissibility falls within a narrow compass, the judge might well not sanction the alternative procedure. In support of this option, it was pointed out in the consultation paper that a system which requires the giving of the same evidence twice in the course of a criminal trial is neither efficient nor economical, and thus goes against the interests of justice.

4.31 To put into effect this proposal for change, amendments to the Criminal Procedure Ordinance (Cap. 221) along the following lines were suggested:

“1. When, in the course of a trial, objection is taken to the admissibility of evidence sought to be adduced by the prosecution, the judge may, if he considers it expedient in the interests of justice so to do, order that the evidence may nevertheless be put before the court, subject to these provisions:

(i) The accused may elect to testify, and call witnesses, before the close of the prosecution case, relating solely to the admissibility of such evidence.

(ii) Where the judge considers that such evidence is not properly admissible he shall, before the close of the prosecution case, rule accordingly.

2. Where the judge has ruled in accordance with paragraph (ii) above, he shall forthwith direct the jury to disregard such evidence and shall direct that any written material relating thereto be withdrawn.”

4.32 In favour of this option, the consultation paper pointed out that providing the trial judge with a discretion as to whether the question of admissibility should be heard in the presence of the jury would ensure that the accused is not unfairly prejudiced, a protection which would be lacking if such hearings automatically proceeded before the jury. As matters stand, it is up to the defence to decide whether or not a voir dire will be held, and in practical terms that effectively means that a voir dire is held in almost every jury case where objection is raised to the admissibility of a confession. Option A would place the decision as to whether or not to hold a voir dire in the hands of the trial judge.

4.33 Only one of those who responded to our consultation paper was in favour of Option A. He considered, however, that the discretion proposed should only be exercised in exceptional circumstances, such as where the allegations of impropriety are straightforward or the only evidence of guilt is the confession itself.

4.34 Understandably, some of the respondents’ arguments against this option are essentially those stated in the general arguments presented earlier in this chapter and we do not intend to repeat details of these arguments here.




Judges’ discretion undermines uniformity


4.35 The key feature of Option A is that it provides the trial judge with a discretion to adopt the alternative procedure in a jury trial. This option was in general treated with suspicion by those who commented on the consultation paper. The main objection lies in the fear that the exercise of judicial discretion would undermine uniformity since there are no clear guidelines as to how the discretion is to be exercised. Allied to this is the concern that the introduction of this additional element of judicial discretion may prompt a multiplicity of appeals, particularly in cases where the trial judge insists on exercising his discretion to allow the issue of voluntariness to be deliberated before the jury in the face of an objection raised by the defence.


Unlikely that the jury can ignore a rejected confession


4.36 As explained earlier in this chapter, the danger of having the jury present at the voir dire proceedings lies in the potential prejudice to the accused. Those who reject Option A believe that the risk is too great that jurors will not be able to put out of their minds the prejudicial nature of a confession which is ruled inadmissible. It is, they argue, better to ensure that the accused receives a fair hearing from the jury on the substantive issue by uniformly excluding the jury from the hearing to determine the admissibility of the confession statement.

4.37 It was suggested by one respondent that a particular difficulty may arise when there is in the same trial more than one accused with confession statements to contest. In those circumstances, if the trial judge in the jury’s presence withdraws the statement of one accused but not that of another, the jury may give undue weight to the statement admitted, reflecting the fact that that accused’s assertion that the confession was not voluntary has been rejected.

4.38 Equally unfair to the accused would be the case where the statement of the co-accused has implicated him in the commission of the offence. The withdrawal of the statement by the judge could not remove the fact that the jury had already seen and heard the statement, and any incriminating evidence it contained.


Inhibition of the accused’s testimony on the issue of voluntariness


4.39 Some respondents are also concerned that if the jury were present at the hearing on admissibility, the accused might be deterred from giving evidence on that issue because of fears that by so doing he might evoke an adverse reaction from the jury.




Causing injustice to both parties


4.40 The possible injustice to the accused which Option A might cause has already been canvassed earlier in this chapter. There is also a risk of injustice to the prosecution, however. If the judge rejects a confession statement, this might be taken by the jury as reflecting adversely on the prosecution witnesses, not only in respect of the question of voluntariness but also on the substantive issue.

Saving of time and costs insufficient justification for removing protection provided by voir dire

4.41 The cumulative effect of these possible injustices led many of the respondents to conclude that the saving of court time and costs is insufficient to justify the adoption of Option A. Ms Corinne Remedios, a barrister, accordingly observes:[63]
“The potentially grave injustice to a defendant of a jury relying on an inadmissible confession cannot be sacrificed in order to achieve a more efficient or economical Court system. The interests of justice must be weighted in the accused’s favour.”

Effective dilution of the right to silence


4.42 A number of respondents were concerned that the jury, who would be present in the voir dire proceedings as a result of Option A, might speculate as to why the accused did not give evidence in the main trial when he had earlier given evidence in the voir dire. The jury might infer guilt from the accused’s exercise of his right to silence. This indirectly undermines the accused’s right to silence, as he might feel compelled under the circumstances to elect to give evidence in the main trial.


Option B - Making the determination of the issue of admissibility of confession statements a matter for the jury in all cases


4.43 This option goes further than Option A and calls for the abolition of the voir dire in all cases by making the question of admissibility a matter for the jury to decide. While the majority of those who responded to the consultation paper were against any of the three options for change presented in that paper, of those who favoured change, most opted for Option B.

4.44 One argument for change presented in the consultation paper was that there seemed little justification for the view that the jury are incapable of putting out from their minds a confession which they have themselves ruled was not voluntarily given and is therefore inadmissible, when the current procedure expects them to be capable of assessing post-voir dire the weight to be given to an admissible confession on which competing evidence is presented as to the manner of its taking. The distinction is, it could be argued, unrealistic and artificial and assumes in the jury a lack of sophistication that has little validity in today’s Hong Kong. The ICAC observed[64] that as jurors in Hong Kong are made up of an average cross-section of the community a properly directed jury:

“... should be more than capable of making an objective assessment of the voluntariness and fairness of a confession, without being ‘tainted’ by knowledge of the issues if the confession were subsequently ruled inadmissible.... We believe that making the question of admissibility of confession statements a matter for the jury in all cases would be preferable to allowing courts a discretion to direct that the question of admissibility be dealt with in the presence of the jury. A consistently uniform procedure, we feel, would be fairer, almost by definition.”

4.45 The consultation paper pointed out that Option B had the effect of minimising and possibly removing the risk of jurors being prejudiced by evidence about a confession which is subsequently ruled inadmissible by the trial judge. Since the decision as to the admissibility of a confession is a matter for the jurors, they would logically readily disregard evidence which they have themselves considered to be inadmissible, as it must be presumed that they would believe in the correctness of their own decision. There would therefore be no question of jurors being prejudiced by evidence relating to a confession which they have themselves ruled inadmissible. In giving their support to Option B, the Immigration Department agreed[65] that since juries are presumed capable of assessing the weight to be accorded to a confession admitted in evidence, there is little reason for the view that they are incapable of putting out from their minds evidence of a confession which they have themselves ruled inadmissible under this option.

4.46 The consultation paper suggested that Option B could be said to provide a more rational approach to the way in which evidence of an alleged statement by the accused is handled. Under current procedure, if the accused denies making a statement at all, that is a matter of fact for the jury to decide. If, however, the accused concedes that a statement was made but claims that it was forced from him, the question of whether or not the statement was taken voluntarily is a matter of law for the judge to decide. The consultation paper pointed out that it was difficult to discern why the latter circumstances should not be equally capable of decision by a properly instructed jury.

4.47 One respondent who supported this argument remarked that it was impracticable to require the jury to draw a distinction between the issues of admissibility of a confession statement and the weight to be attached to it. He suggested that the two issues should be merged, and that all confession statements should be made admissible before the jury. It would then be a matter for the jury as to what weight should be given to them (the issues of voluntariness and fairness could be canvassed at that stage). This would obviate the need for a voir dire altogether.


Option B a less flexible option


4.48 Some of those who argued against Option B pointed out that it was a less flexible alternative than Options A or C, which would at least allow a residual discretion for the judge to conduct the voir dire in the absence of the jury. Option B ruled out such a possibility. The jury would always hear the confession, whatever their conclusion as to voluntariness might ultimately be.


Prejudice to the accused


4.49 The possibility of juries blurring the general issue of truthfulness with the special issue of voluntariness, to the prejudice of the accused, was raised among others by Mr Harry Macleod, Deputy Director of Public Prosecutions, who observed that[66]:

“In hearing a voir dire in which they are the arbiter of facts, it would not be wholly surprising for the jury to form a judgment as to the authenticity and truth of a confession, even though those issues may not necessarily be germane to the issue they have to decide, i.e. voluntariness. If they were to conclude that the confession was not voluntary, they may nevertheless have formed the view that the confession was both authentic and true. This view would be more sharply focused and entrenched than if they had been mere spectators of a voir dire conducted pursuant to Option A or C. It is submitted that in such circumstances it would be extremely difficult for the jury to exclude the confession from their minds.”


Discourages the accused from giving evidence on the general issue


4.50 A general concern was expressed by those who object to Option B that the jury’s ruling on the issue of admissibility might be taken as an “indication” of the jury’s attitude to the credibility of the accused and his witnesses. An adverse ruling might discourage the accused from giving further evidence on the general issue as he might consider that the jury would disbelieve his evidence by virtue of their “ruling in” of the confession statement.


Jurors would become judges of law


4.51 Some respondents expressed concern that allowing the jury (who are judges of fact) to rule on the special issue of admissibility (which is a question of law) would usurp the judge’s function. The issue of admissibility is a complex one, involving legal considerations which might be asking too much of lay jurors who are neither professionally qualified nor trained to take up the task.

4.52 It was argued by some that the practical effect might well be that juries admit all confessions as evidence, a view summarised by barrister Mr John Dunn:

“The implementation of Option B would not mean in practice that juries would actually decide upon the admissibility of confessions. The true effect of Option B would be that all confessions would be admitted into evidence and juries would then simply decide how much weight they placed upon them.”[67]


The accused would always have a case to answer


4.53 Mr Dunn argued that even if the prosecution witnesses have all been discredited in cross-examination and there is grave suspicion that the confession was not voluntarily obtained, the case would nevertheless continue to its formal conclusion. In the same letter, Mr Dunn remarked:

“Presumably the jury would not be called upon at any time to make a formal ‘ruling’ on admissibility, and in any case they could not do so until the end of the trial when they had heard all the evidence from both sides. This means that both the Prosecution and the Defence would have to conduct the entire trial without knowing whether this crucial piece of evidence (frequently the only piece of evidence) would be admitted or not. If the Prosecution case is such that it will inevitably fail without the confession evidence, which is not uncommon, then if the confession is rejected by the judge after a voir dire, the trial will end after a successful defence submission at the close of the Prosecution case. It is submitted that it is clearly in the interests of justice that if the prosecution cannot establish even a prima facie case, then the trial should not continue and the defendant should not remain in jeopardy, but should be discharged. If however the judge does not know whether or not the confession will be adjudged admissible by the jury, then how can he make a sensible decision on whether or not in law the Prosecution has made out a prima facie case? Presumably he must rule, in accordance with R. v Galbraith that where there is evidence on which the jury could convict if they believe the witnesses, then he must let the case go on.”

4.54 If the intention of Option B is to save court time and costs, it would have failed in its purpose. Even though the only evidence against the accused is a confession which is ultimately ruled inadmissible, a full trial must nevertheless be conducted. Under the present system, if the confession is ruled inadmissible at the conclusion of the voir dire, the trial need not continue further.

Option C - Granting the court a discretion to direct that the question of admissibility be dealt with in the presence of the jury, coupled with a lowering of the standard of proof for determining voluntariness to that of civil proceedings


4.55 Option C in the consultation paper differed from the discretion proposed in Option A in that, under the former, as a general rule a voir dire should be held in the absence of the jury, thus giving the judge a more limited discretion to proceed by way of the alternative procedure. However, the judge would be given the authority to exercise his discretionary power to take into account practical considerations. Option A, however, would provide the trial judge with a largely unfettered discretion to direct that the question of admissibility be heard in the presence of the jury. Under Option C, the determination of the admissibility of evidence would in general be made by the trial judge in a voir dire in the jury’s absence, though the judge would have a discretion to direct that the matter be dealt with in the presence of the jury. If the court at the end of the day orders that the jury is to be present during the voir dire, evidence adduced in the voir dire may also be used in the trial, subject to the exclusionary rules, without the need to repeat it.

4.56 Option C also differs from Option A in that it proposed that the standard of proof required of the prosecution in proving the voluntariness of a confession statement should be on the balance of probabilities, and not the higher criminal standard of proof beyond reasonable doubt currently adopted in Hong Kong. This standard of proof had been described as a “variable civil standard” since it allows the standard applied by the court to take into account the nature and importance of the preliminary question of fact, in order to deter improper conduct by the law enforcement agencies.

4.57 Only one of those who responded to our consultation paper was in favour of the adoption of Option C, though there were some who favoured other options who also argued that the standard of proof should be changed. One such was the Immigration Department, who argued[68] that the change would not necessarily remove from the accused the greater protection now enshrined in the present conditions governing the admissibility of confession statements. They explained that even if the statement is admitted on the basis of the civil standard, the jury at the end of the day must still be satisfied beyond reasonable doubt that the accused is guilty, before a conviction can be returned.

4.58 The Hong Kong Democratic Foundation also gave their support to a change in the standard of proof:

...particularly bearing in mind that in voir dires the prosecution is called upon to prove a negative - that is that the statement has not been improperly procured, that there has not been force used, nor duress, nor an offer of advantage. And we say this also conscious of the fact that there is a ‘long-stop’ in that the prosecutions case as a whole still has to be proved beyond all reasonable doubt.

4.59 A similar view was expressed by the Complaints Against Police Office (CAPO)[69], who commented that the lowering of the standard of proof to that of civil proceedings would not affect the fact that the prosecution’s case must stand up to the scrutiny of the judge, or the judge and jury.


Prejudice to the accused


4.60 The general consultation responses suggesting that the jury’s presence in voir dire proceedings would be prejudicial to the accused apply equally to Option C. For some, those reservations are exacerbated by the changing of the standard of proof to the balance of probabilities.

4.61 The arguments on this point have been fully canvassed earlier in this chapter. Suffice to say that those opposed to Option C considered that it presented as great a risk of prejudice to the accused as the other alternatives proposed. The principal concern is as to the jury’s ability to cast from their minds inadmissible and prejudicial evidence heard in relation to the voir dire proceedings.


The two standards of proof would confuse the jury


4.62 Specifically in relation to the proposal to lower the standard of proof, some respondents doubted if an untrained jury would be able to discern the different requirements arising from the criminal and civil standards of proof. The time devoted by judges to explaining the criminal standard provides an indication of the complexities involved. To burden the jury in addition with a different standard of proof for one aspect of the proceedings might prove too taxing on the jury.


Inadequate protection for the accused

4.63 A number of respondents argued that a lowering of the standard of proof would significantly reduce the existing protection against abuse by the law enforcement agencies. Under the present system, the prosecution is required to prove beyond reasonable doubt in the voir dire that the confession statement was obtained voluntarily, before the statement can be admitted in evidence before the jury. Should the standard of proof be lowered, argued some respondents, confession statements which would otherwise be held inadmissible under the present criminal standard would be made admissible for the jury who in turn might return a guilty verdict on an accused who would otherwise be acquitted. Barrister Mr Joseph W.Y. Tse observed[70]:

“This option can achieve nothing except to remove the safeguards of a defendant in a trial. If the standard of proof is lowered, it can be foreseen without any difficulty that almost all challenges to a statement would be unsuccessful. Judges would have no difficulty in being satisfied of the voluntary nature of statements. That would be the same as if a defendant had no right to challenge a statement at all. The law enforcement agencies would in turn be encouraged to rely more heavily on getting confessions from suspects. The consequences would be that there would be more and more cases involving a voir dire and practically all of them would turn out to be a futile exercise of useless challenges.”
