Options for reform

________________________

 

 

 

A model of the present law

 

8.1           The present law of hearsay in Hong Kong criminal proceedings can be described in terms of a model having the following three components:

 

(a)       a blanket rule of exclusion ("exclusionary rule")

(b)       a fixed number of specific common law and statutory exceptions to the exclusionary rule (what may be termed "pigeonhole exceptions"); and

(c)        the absence of a judicial discretion to admit evidence caught by the exclusionary rule ("no discretion to admit").

 

8.2           The question of reform requires an examination of each of these components.  As regards the first component, the most basic question to consider is whether to keep the exclusionary rule or to discard it along the lines of the reform of civil hearsay.  Even if the exclusionary rule is kept, should the scope of application be narrowed by, for example, restricting the definition of hearsay evidence or the types of proceedings in which the rule should operate?

 

8.3           A consideration of the “pigeonhole exceptions” also raises a number of important issues.  Should the common law exceptions be abolished, or codified, or left as they are?  If they are codified, should individual exceptions be widened to remove any anomalous restrictions?  Are the existing statutory exceptions satisfactory or are there reasons to reform some or all of them?  Should new “pigeonhole exceptions” be enacted?  Possible reform of the third component requires consideration of two main issues: whether to codify a discretion to admit and, if so, what form should it take? 

 

8.4           Given the many possible answers to each question (and the ways in which those answers may be combined), the number of possible options for reform is enormous.  In our deliberations, 14 different options for reform were identified and considered.  It was readily determined that a number of these options were unacceptable for various reasons.  Three main options became the subject of further debate and consideration.  In the result, a consensus was reached on a single proposed model of reform.  The proposed model of reform, described in greater detail in the next chapter, recommends the following:

 

(a)       redefining hearsay evidence so that it no longer includes implied assertions;

(b)       retaining the exclusionary rule;

(c)      abolishing the common law exceptions to the hearsay rule, except those relating to confessions, admissions, statements against interest, statements in furtherance of a conspiracy, and opinion evidence;

(d)       enacting a core scheme that confers a discretion on the trial judge to admit hearsay evidence on the basis of a defined test of necessity and threshold reliability;

(e)       incorporating sufficient safeguards within the core scheme to protect the innocent from being convicted and to prevent the integrity of the trial process from being compromised;

(f)         repealing certain statutory exceptions, substantially modifying others, and adding new exceptions, particularly for prior consistent statements and evidence admitted by consent.

 

 

Rejected options and proposals

 

The polar extremes: no change and free admissibility

 

8.5           Having identified the numerous shortcomings of the present law and recognizing the repeated criticisms of that law by distinguished jurists and academics in the common law world, we conclude that maintaining the status quo is not a realistic option. 

 

8.6           At the other extreme, we also do not recommend the abolition of the exclusionary rule and the unrestricted free admissibility of relevant hearsay evidence.  Indeed, even after its significant reform, hearsay evidence in civil proceedings may still be excluded, albeit in exceptional circumstances.[1]  In the context of criminal proceedings, there are good reasons for ensuring that the admission of hearsay evidence remains the exception and does not become the norm.  The reasons for retaining the exclusionary rule include the following:[2]

 

(a)               without it, evidence would "not need to meet any standard of reliability, nor to be unavailable in any other form, in order to be admitted" and there would be no safeguards against dubious and unreliable hearsay;[3]

 

(b)               free admissibility "fails to attach any importance to the need for cross-examination";[4]

 

(c)               the lack of opportunity for the defence to cross-examine admitted hearsay of any type would arguably infringe rights protected under the Basic Law and Hong Kong Bill of Rights Ordinance;

 

(d)               fact-finders would be exposed to evidence of unidentified persons;[5]

 

(e)               fact-finders would be exposed to multiple hearsay.  The "dangers of inaccuracy and ambiguity increase with the number of times a story is repeated";[6]

 

(f)                 the direction that the judge would have to give to the jury in respect of multiple hearsay evidence could be extremely complicated.  A jury is likely to be easily confused by such a direction;[7]

 

(g)               free admissibility would "leave the court open to a vast amount of evidence, much of it superfluous".  This would unduly prolong hearings;[8]

 

(h)               free admissibility would encourage a lax approach to investigation and prosecution; and

 

(i)                 policing fabricated evidence, including exculpatory evidence, would be particularly difficult.

 

8.7           For the above reasons, options just short of these two extreme positions are also unsatisfactory.  One option is to remove some of the existing anomalies with the statutory exceptions to hearsay without any major changes to the general structure of the law.  The Sub-committee considers that this kind of minor tinkering, though a step in the right direction, is insufficient on its own to address all the shortcomings of the existing law.  In accordance with the terms of reference, the Sub-committee believes in principle that reform of hearsay in criminal proceedings can and should be more comprehensive.  As mentioned in Chapter 1, there is little prospect of judicial change to the law.  It is worth repeating the sentiments expressed by the Court of Final Appeal on the question of reform:              

 

"In R v Blastland, all the other Law Lords hearing the appeal agreed with Lord Bridge of Harwich who (at p.52H) referred to the principle established in Myers v DPP 'never since challenged, that it is for the Legislature, not the Judiciary, to create new exceptions to the hearsay rule'.  In Bannon v R (1995) 185 CLR 1, a case before the High Court of Australia, Brennan CJ said (at p.12) that the creation of a new exception to the hearsay rule 'would require a general review of the hearsay rule, its history, purpose and operation'.  The Law Reform Commission would appear to be the best body suited to conduct such a general review."[9]

 

8.8           One member of the Sub-committee had expressed an initial interest in the option of free admissibility, subject to a residual discretion to exclude.  This was a proposal based on the present law governing civil hearsay.  After some discussion, the Sub-committee unanimously agreed that this option had insufficient safeguards to address the concerns listed in paragraph 8.6 above. 

 

 

Recommendation 3

 

We recommend that the polar extreme options of no change or free admissibility, or options just short of these extreme positions, be rejected.  We believe these options either inadequately address the shortcomings in the law or, at the other extreme, have insufficient safeguards.

 

 

Best available evidence

 

8.9           The option of freely admitting the best available evidence was referred to in the Auld report as follows:

 

"Professor John Spencer … argued that there should be a generally inclusionary system subject to a 'best available evidence' principle. That is, each side would be obliged to produce the original source of the information if the source is still available."[10]

 

From "the fundamental standpoints that rules of evidence should facilitate rather than obstruct the search for truth and should simplify rather than complicate the trial process", Lord Justice Auld believed there was merit in making relevant hearsay evidence generally admissible subject to the best available evidence principle.[11]  However, the English Law Commission rejected this option because it effectively required judges and magistrates to assume an inappropriate inquisitorial role in ensuring that the best available evidence was brought before the court.[12]  The Law Commission also believed that "it would be difficult to ensure that the parties respected the obligation to produce the source of their evidence where possible."[13]  The Law Commission's views were reflected in the hearsay reform proposals contained in the Criminal Justice Act 2003 (UK).[14]

 

8.10                This option is unanimously rejected by the Sub-committee.  In addition to the reasons given by the Law Commission, we believe that this option has insufficient safeguards to prevent the admission of unreliable evidence.  Furthermore, this option is likely to lead to considerable unproductive time being spent, both pre-trial and during trial, on determining whether an item of evidence is the "best available".

 

 

Recommendation 4

 

We recommend that the “best available evidence option” be rejected, for it is impractical for the parties to comply with, difficult for the court to enforce without becoming inquisitorial, contains insufficient safeguards, and may contribute to inefficient use of court time.

 

 

Discretion to admit only defence hearsay

 

8.11                The proposal to give the defence more liberal rights than the prosecution to adduce hearsay evidence was considered by both the Scottish and English Law Commissions.[15]  In the interest of avoiding wrongful convictions, the Scottish Commission noted that some countries have relaxed the hearsay rule more for the defence than the prosecution.[16]  For example, under the Federal Australian Evidence Act 1995, statements of unavailable witnesses adduced by the defence can be admitted without having to satisfy a separate reliability condition which prosecution evidence would have to surmount.[17]  The Supreme Court of Canada, in defining the scope of a common law declaration against penal interest exception, held that evidence admitted under this exception could only be used to exculpate the defendant rather than for purposes of inculpation.[18]

 

8.12                It is often thought that the proposal is required by international human rights norms.  In respect of the European Convention for the Protection of Human Rights and Fundamental Freedoms (the "European Convention"], the English Law Commission noted that

 

" … although Article 6(3)(d) puts limits on the extent to which the prosecution may make use of hearsay evidence, nothing in Article 6 restricts the use of hearsay evidence by the defence."[19] 

 

But while it is one thing to say that a restrictive exclusionary rule impairs a defendant's right to make full answer and defence, it is another thing to say that an equitable relaxation of the same rule for the prosecution will inevitably infringe a defendant's fair trial rights.  In their respective reports, both the English and Scottish Law Commissions came to the same conclusion that a reformed hearsay rule that applies in the same manner to both defence and prosecution evidence will not infringe the European Convention so long as there are sufficient safeguards against the conviction of the innocent.[20]

 

8.13                The Scottish Law Commission rejected the idea of differential treatment for prosecution and defence, being unconvinced of its necessity or desirability.  The Commission wrote:

 

"One consideration is that curious results might follow.  The prosecution might be entitled to cross-examine a defence witness on hearsay evidence he had given in chief which the prosecution, had they led him as a witness, would not have been entitled to elicit from him.  In a trial where there were co-accused, one accused might be entitled to elicit from a defence witness hearsay evidence implicating a co-accused which the prosecution would not have been entitled to lead."[21]

 

Aside from these practical problems, the Scottish Law Commission also felt that it was:

 

"necessary to maintain or improve, as far as possible, the effectiveness of the criminal justice system not only in acquitting the innocent but also in convicting the guilty."[22] 

 

The English Law Commission agreed, and expressed concern at the ease with which a guilty defendant could be acquitted by raising a reasonable doubt through " … the use of manufactured or very low quality hearsay … .".[23]

 

8.14                Despite some initial interest by one member, the Sub-committee ultimately rejected the option of allowing a discretion to admit only defence hearsay.  We agree with both the English and Scottish Law Commissions that in principle differing standards of admissibility for different parties are unacceptable.  As all of the shortcomings of the present hearsay rule impede the prosecution, as well as the defence, to ignore the difficulties facing the former would be unsatisfactory.  The public interest requires cogent and reliable prosecution evidence to be received by the tribunal of fact in coming to an accurate verdict, particularly in cases involving serious crimes.  The Canadian case of R v Khan provides an example of the possible injustice that could result for the prosecution.[24]  In this case, the defendant, a medical doctor, was charged with sexually assaulting a 3½ year old girl while her mother was in an adjacent private room.  Shortly after leaving Dr. Khan's office, the mother noticed a wet spot visible on the girl's clothing, which was subsequently found to contain semen and saliva.  When asked about it, the daughter, in language that bore the stamp of reliability, disclosed the sexual assault.  Had the Supreme Court of Canada not liberalised the hearsay rule in this case to allow the admission of the child's disclosure to her mother, the case could never have been brought since the child was incompetent to testify at trial.

 

 

Recommendation 5

 

We recommend that any reforms of the law of hearsay in criminal proceedings should apply in the same manner to both the prosecution and defence. 

 

 

Broad discretion to admit - the South African model

 

8.15                In 1988, South Africa reformed its hearsay rule by abolishing the common law exceptions and replacing them with a single discretionary scheme, which applied in both civil and criminal proceedings.[25]  The heart of the scheme is that the court must consider seven enumerated criteria in deciding whether the evidence should be "admitted in the interests of justice".[26]  These seven criteria are:

 

(i)        the nature of the proceedings;

(ii)       the nature of the evidence;

(iii)      the purpose for which the evidence is tendered;

(iv)      the probative value of the evidence;

(v)       the reason why the evidence is not given by the person upon whose  credibility the probative value of such evidence depends;

(vi)      any prejudice to a party which the admission of such evidence might entail; and

(vii)     any other factor which should in the opinion of the court be taken into account[27]

 

The Supreme Court of Appeal of South Africa has observed that:

 

"The 1988 Act was … designed to create a general framework to regulate the admission of hearsay evidence that would supersede the excessive rigidity and inflexibility – and occasional absurdity – of the common law position.  In the result … the 1988 Act retained 'the common laws caution' about receiving hearsay evidence, but 'altered the rules governing when it is to be received and when not', principally by glossing the common law exceptions with the general criteria of relevance, weight and the interests of justice …"[28]

 

8.16                We generally believe the South African scheme has merit in terms of its simplicity and its ability to address the inflexibility and irrationality of the existing law.  However, the Sub-committee was concerned about the open-endedness of the discretion (ie "admitted in the interests of justice").  There were three general concerns.  Without greater direction as to how to apply and weigh the enumerated factors, there is a risk that courts could reach inconsistent admissibility decisions.  This in turn would contribute to uncertainty in the law, at least until a higher court provides the necessary guidance on the application of the discretion.  The third and related concern is the potential to invite an increased number of unmeritorious attempts to admit hearsay due to ignorance, confusion or mistake about the law.  In the result, we thought it was possible to devise a scheme, imbued with the spirit of the South African model, but offering clear signposts in the interests of certainty and consistency in decision-making, protection for the rights of the accused, and respect for the integrity of the trial process.

 

 

Recommendation 6

 

We recommend that the South African model, which admits hearsay on an entirely discretionary basis "in the interests of justice", be rejected because of concerns with the open-endedness of the discretion.

 

 

The three main options

 

Option 1 ("the English model"): Wide “pigeonhole exceptions” with a narrow discretion to admit

 

8.17                In 1997, the English Law Commission published a comprehensive report with recommendations for reforming the hearsay rule in criminal proceedings.  The recommendations were adopted in the Criminal Justice Act 2003 (UK), which received royal assent on 20 November 2003.  The new reforms have the following distinctive components (hereinafter collectively referred to as “the English model”):

 

(a)       a re-definition of hearsay evidence that excludes from its ambit implied assertions;[29]

 

(b)       preservation of some established common law exceptions, such as public information, reputation, res gestae, confessions and admissions, common enterprise, and expert evidence;[30]

 

(c)        admissibility of hearsay statements from five categories of unavailable witnesses (the declarant is dead, unfit to be a witness, outside the United Kingdom, cannot be found, or is unavailable due to fear).  Unavailability due to fear can only be the basis of discretionary admission "in the interests of justice";[31]

 

(d)       admissibility of written police statements of persons who cannot reasonably be expected to have any recollection of the matters dealt with in the statement;[32]

 

(e)       a narrow residual discretion to admit hearsay "in the interests of justice";[33]

 

(f)         a discretion to exclude hearsay evidence if "to admit it would result in [an] undue waste of time";[34]

 

(g)       the judge's power in jury trials to stop the case where a conviction based wholly or partly on unconvincing hearsay evidence would be unsafe.[35]

 

8.18                While we agree with certain aspects of the English Law Commission's proposals, we have reservations about others, particularly the breadth of the exception for unavailable witnesses and the terms of the residual discretion to include. 

 

8.19                Under the English model, a declarant's out-of-court statement is automatically admissible if he is satisfactorily identified and

 

(a)       is dead;

(b)       is unfit to be a witness because of his bodily or mental condition;

(c)        is outside the United Kingdom and it is not reasonably practicable to secure his attendance;

(d)       cannot be found although reasonably practicable steps have been taken to find him; or

(e)       cannot reasonably be expected to have any recollection of the matters dealt with in a written statement made for the purpose of a criminal investigation.[36]

 

Further, with the leave of the court, out-of-court statements of a person who through fear does not give oral testimony of the relevant evidence may be admitted if the person is satisfactorily identified and it is in the interests of justice to do so.[37]

 

8.20                Statements admitted under these exceptions do not come with any guarantees as to reliability.  The principle behind their admission is merely necessity due to the absence of the declarant's oral evidence at trial.  These exceptions, although offering a fair degree of certainty and consistency in decision-making, have an over-inclusive effect by allowing in all types of relevant evidence, including unreliable hearsay evidence.  The English model has three mechanisms to correct this over-inclusiveness.  First, there is the express preservation of the power under section 78 of the Police and Criminal Evidence Act 1984 ["PACE"] to exclude evidence affecting the fairness of the trial.  Secondly, there is a newly enacted discretionary power to exclude hearsay evidence under section 126(1) of the Criminal Justice Act 2003.  Section 126 of the Criminal Justice Act 2003 provides as follows:  

 

(1)  In criminal proceedings the court may refuse to admit a statement as evidence of a matter stated if:

 

(a)       the statement was made otherwise than in oral evidence in the proceedings, and

 

(b)       the court is satisfied that the case for excluding the statement, taking account of the danger that to admit it would result in undue waste of time, substantially outweighs the case for admitting it, taking account of the value of the evidence.

 

(2)     Nothing in this Chapter prejudices

 

(a)      any power of a court to exclude evidence under section 78 of the Police and Criminal Evidence Act 1984 (c 60) (exclusion of unfair evidence), or

 

(b)      any other power of a court to exclude evidence at its discretion (whether by preventing questions from being put or otherwise).”

 

Finally, there is another new power of the judge in jury trials to stop the case at any time after the completion of the prosecution’s case if the case against the defendant is based wholly or partly on a statement not made in oral evidence in the proceedings, and the hearsay evidence is so unconvincing that, considering its importance to the case against the defendant, his conviction of the offence would be unsafe.[38]   

 

8.21                Hong Kong, however, has none of these statutory mechanisms, particularly section 78 of PACE.[39]  Furthermore, the Sub-committee believes that if “pigeonhole exceptions” are to be used, they need to provide more assurances as to the reliability of the evidence.  Following the common law tradition, categorical exceptions to hearsay must clearly set out those circumstances and conditions that capture the inherent reliability of the evidence to be admitted.

 

8.22                Given the breadth of the exception for unavailable witnesses, the new discretion to admit hearsay was intended by the Law Commission to be used only in narrow circumstances.  Where a hearsay statement does not fit within any of the specific exceptions, the judge has a power to admit the statement in the interests of justice, such as where, for example, the evidence was particularly cogent of the defendant's innocence.  Section 114 of the Criminal Justice Act 2003 sets out the terms of the power as follows,

 

 "(1)    In criminal proceedings a statement not made in oral evidence in the proceedings is admissible as evidence of any matter stated if, but only if—

(d)       the court is satisfied that it is in the interests of justice for it to be admissible.

 

(2)       In deciding whether a statement not made in oral evidence should be admitted under subsection (1)(d), the court must have regard to the following factors(and to any others it considers relevant)—

(a)       how much probative value the statement has (assuming it to be true) in relation to a matter in issue in the proceedings, or how valuable it is for the understanding of other evidence in the case;

(b)       what other evidence has been, or can be, given on the matter or evidence mentioned in paragraph (a);

(c)        how important the matter or evidence mentioned in paragraph (a) is in the context of the case as a whole;

(d)       the circumstances in which the statement was made;

(e)       how reliable the maker of the statement appears to be;

(f)         how reliable the evidence of the making of the statement appears to be;

(g)       whether oral evidence of the matter stated can be given and, if not, why it cannot;

(h)       the amount of difficulty involved in challenging the statement;

(i)         the extent to which that difficulty would be likely to prejudice the party facing it."

 

8.23                Notwithstanding the enumerated list of factors to consider in section 114(2), the main difficulty lies with the vague terms of the discretion in section 114(1)(d).  As with the South Africa model, in respect of which we summarised our concerns at paragraph 8.16 above, the open-ended nature of this discretion does not sufficiently safeguard against the dangers of hearsay evidence.  With nine non-exhaustive factors to consider, trial courts will still want guidance on how these factors are to be weighed in applying the discretion.  Until proper guidance is given by the appellate courts, some uncertainty in the law and inconsistent decisions are inevitable.  Though the Law Commission envisaged this discretion being exercised in narrow circumstances, the language of the power provides little assurance that this will be the case.  Indeed, it was this concern, stated most clearly by Lord Thomas of Gresford in the excerpt below, that led a majority of the members of the House of Lords to vote in favour of removing this discretion from the original Bill:

 

"the discretion is handed over entirely to the court as to whether the hearsay evidence should be admitted, subject only to subsection (2), where there are certain factors for the judge to bear in mind.  Members of the Committee may feel that they are fairly obvious matters, but the provisions are extremely vague and broad and introduce into the law of evidence in criminal cases hearsay evidence wholesale.  It can never be certain for a defendant that he will not face evidence of this sort; whether a judge admits it or not, it will be a matter for application, either pre-trial or during the trial.  We object in principle to the introduction of hearsay evidence of that type."[40]

 

We echo these concerns and favour a more rigorous and specifically defined discretionary power that is expressly tailored to the underlying principles for admitting hearsay evidence.

 

 

Recommendation 7

 

We recommend that Option 1 (the English model) be rejected for two main reasons: its categories of automatic admissibility provide insufficient assurances of reliability and the terms of the residual discretion to admit hearsay are too open-ended and vague.

 

 

Option 2 ("the United States model"): Codification

 

8.24                The present United States federal law sets out a detailed and comprehensive codified scheme for the admission of hearsay evidence in both civil and criminal proceedings.[41]  This scheme has the following essential components:

 

(a)       a re-definition of hearsay evidence that excludes implied assertions;[42]

 

(b)       retention of the blanket exclusionary rule in codified form;[43]

 

(c)        abolition of the common law exceptions;[44]

 

(d)       a codification of 28 “pigeonhole exceptions”, most based on the old common law exceptions.  Statutory exceptions are divided into two categories: those applicable where the availability of the declarant as a witness is immaterial, and those applicable where such availability is material but the declarant is unavailable;[45]

 

(e)       a residual discretion to admit hearsay where the statement has "equivalent circumstantial guarantees of trustworthiness" to the “pigeonhole exceptions” and

 

(i)         the statement is offered as evidence of a material fact;

(ii)        the statement is more probative on the point for which it is offered than any other evidence which the proponent can procure through reasonable efforts; and

(iii)       the general purposes of these rules and the interests of justice will best be served by admission of the statement into evidence.[46]

 

8.25                Several Sub-committee members were initially impressed with the US model's comprehensive approach to reform and its use of precise and tight language to minimise uncertainty and abuse of the scheme.  The US model essentially puts the common law of hearsay on a statutory basis while adding a much needed residual discretion to admit.  In contrast to the South African and English models, this discretion requires that the judge find "equivalent circumstantial guarantees of trustworthiness" before exercising the discretion, a test that members found more attractive.

 

8.26                During the Sub-committee’s deliberations , it readily became apparent that the task of codifying each of the common law exceptions would be a major one.[47]   Doubts were cast on the feasibility of such an exercise.  It was generally felt that it would not be possible to cater for all justifiable circumstances.  Members of the Sub-committee were also concerned that new statutory provisions might give rise to a new set of interpretative problems, with possible ramifications beyond the law of hearsay, such as the law of confessions and statements of witnesses.  If a key aim of reform is to simplify the law and render it more coherent, then it would seem sensible to minimise (rather than increase or maintain) the number of “pigeonhole exceptions”. 

 

8.27                We identified two alternatives to full codification of existing exceptions.  If, because of shared rationales, existing exceptions were covered by the terms of an inclusionary discretion, the existing exceptions could simply be abolished.  The idea that any specific exceptions should be subordinate to the general principles that underlie the admissibility of hearsay has already been reflected by the courts in Canada.  In a series of important decisions, the Supreme Court of Canada recognised a common law judicial discretion to admit hearsay according to the principles of necessity and reliability.  In 2000, the Court had to confront the question of the relationship between the new principled approach and the existing common law exceptions.[48]  The majority of the Court held that if the traditional exceptions to hearsay are to co-exist with the principled approach, where there is conflict between a traditional exception and the principled approach, the former must be "[p]roperly modified to conform to the principled approach".[49]  By analogy, a newly enacted principled discretion to admit hearsay should generally supplant overlapping exceptions.

 

8.28                Codification also assumes that there is a need to abolish the common law in its entirety.  It ignores the possibility that some common law rules work perfectly well and can be left alone.  The English model employs this strategy of retaining some of the existing law, and we agree that it may be preferable to preserve some common law exceptions rather than to codify or abrogate them. [50]

 

 

Recommendation 8

 

We recommend that Option 2 (the United States
