Cardinal principles and the

shortcomings of the present law

 

 

__________________________________________

 

 

 

4.1           The Hearsay Sub-committee¡¦s task of considering and making recommendations for reform of the hearsay rule involved, as an initial exercise, consideration of the rule itself in its implementation, as well as the application of the exceptions to it and, thus, whether its implementation resulted in any shortcomings.  Recommendations for reform would only be necessary were shortcomings in the rule established.

 

 

Widespread criticism of the common law position

 

4.2           The experience of other jurisdictions with similar regimes is that the existing hearsay rule with its haphazardly developed exceptions has many anomalous consequences, resulting in probative, reliable evidence being excluded from consideration by the tribunal with the real potential for injustice to the public interest, including the interest of the accused.  Criticisms are widespread and longstanding, emanating from judges, academic writers and law reform bodies:

 

1.    Cross & Tapper[1]:

 

¡§The hearsay rule has often been regarded as one of the most complex and most confusing of the exclusionary rules of evidence.  Lord Reid said that it was ¡¥difficult to make any general statement about the law of hearsay which is entirely accurate.¡¦   Both its definition, and the ambit of exceptions to it were unclear.  It led to the exclusion of much reliable evidence, and, on that account, exceptions were created ad hoc, often without full consideration of their implications."

 

2.       The Auld Report[2]:

 

¡§ 95  The rule against hearsay in criminal proceedings, like many other past and present rules of inadmissibility in that jurisdiction, has its origin in the late 18th and early 19th centuries when the cards at trial were so stacked against defendants that judges felt the need to even the odds. .... In civil matters, it has been abolished completely. ....  On one view, it tends to exclude weak evidence and to ensure that a defendant may question his accusers, thus preserving the oral character of the English trial.  On the other, it is capable of being too restrictive so as to work injustice either way, and, in its artificiality, interferes with the smooth running of the trial process.

 

96  It is common ground that the present law is unsatisfactory and needs reform.  It is complicated, unprincipled and arbitrary in the application of a number of the many exceptions.  It can exclude cogent and let in weak evidence.  It wastes court time in requiring it to receive oral evidence when written evidence would do.  And it confuses witnesses and prevents them from giving their accounts in their own way.

 

103 ¡K The need and form of reform of the rule against hearsay should be approached 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.  Inherent in a search for truth is fairness to the defendant and his protection from wrongful conviction - but it should not be forgotten that the present rule can operate unfairly against a defendant as well as the prosecution."

 

3.       R v Kearley[3] per Lord Griffiths:

 

¡§In my view the criminal law of evidence should be developed along common sense lines readily comprehensible to the men and women who comprise the jury, and bear the responsibility for the major decisions in criminal cases.  I believe that most laymen if told that the criminal law of evidence forbade them even to consider such evidence as we are debating in this appeal would reply ¡¥Then the law is an ass¡¦" ¡K  The hearsay rule was created by our judicial predecessors and if we find that it no longer serves to do justice in certain conditions then the judges of today should accept the responsibility of reviewing and adapting the rules of evidence to serve present society."

 

  1. Lamer CJ in R v Smith[4] :

 

¡§¡K the approach that excludes hearsay evidence, even when highly probative, out of the fear the trier of fact will not understand how to deal with such evidence, is no longer appropriate.  In my opinion, hearsay evidence of statements made by persons who are not available to give evidence at trial ought generally to be admissible, where the circumstances under which the statements were made satisfied the criteria of necessity and reliability set out in Khan and subject to the residual discretion of the trial judge to exclude the evidence when its probative value is slight and undue prejudice might result to the accused."

 

  1. Professor Zuckerman[5]:

 

¡§The hearsay rule fulfils neither of these conditions [conformity with the common sense, and secondly, uncertainty in application]  ...  The rule is at odds with common sense and as a result our judges have had to resort to numerous ploys to arrest the more extreme excesses of its operation.  These efforts have made the rule more flexible and have rightly made admissibility more dependent on probative force than on conformity to the legal definition, but this only helps, in turn, to call into question the benefits to be gained from the continued existence of the rule."

 

  1. Bruce & McCoy[6]:

 

¡§The rule has attracted a good measure of criticism.  Probably, the strongest criticism of the law is that the rule operates so as to exclude evidence where a witness who can speak directly about relevant events is unavailable, but that witness has either made a record or has told another person of those events (the latter being available to testify) in circumstances where one would, in ordinary life, regard the recording or relating of the event to be reliable.  The rule has been described by Lord Reid as 'absurdly technical'.  Diplock LJ once confessed the rule has ' little to do with common sense'.  Another serious criticism is that the rule applies with equal force to both prosecution and the defence and on the basis that it is presently applied may exclude evidence upon which the accused may rely to establish his innocence."

 

  1. Preface  to the  New Zealand Law Commission report[7]:

 

¡§¡K in its present form the law of evidence is a patchwork of disparate elements that have never been co-ordinated and whose effect is frequently disputed by experts.  Problems resulting from ancient rules of the judge-made common law, themselves often neither precise nor readily accessible, have been met by ad hoc statutory reforms which have in turn presented difficulties of construction and of scope."

 

8.   The English Law Commission summarised the criticisms directed at the rule as follows:

 

"There is no unifying principle behind the rule and this gives rise to anomalies and confusion.  Court time is wasted because of the lack of clarity and complicated nature of the rule.  Cogent evidence may be kept from the court, however much it may exonerate or incriminate the accused, because the fact-finders are not trusted to treat untested evidence with the caution it deserves, but if hearsay is admitted there is nothing to prevent them from committing on it alone.  Witnesses may be put off by interruptions in the course of their oral evidence.  Whether evidence will be let in or not is unpredictable because of the reliance on judicial discretion."[8]

 

9.       The Scottish Law Commission identified

 

"¡K two principal disadvantages.  First it may result in injustice by depriving the court of information which would be of value in ascertaining the truth¡K[T]he rule offends against the general principle that all relevant evidence should be admissible.  Secondly, the technicality of the rule offends against the general principle that the law should be as clear and simple as possible.

 

We note that the evidence which is excluded by the rule not only is relevant, but also may well be reliable.  It seems to us impossible to assert as a general proposition that hearsay evidence is necessarily less reliable than direct evidence.[9]"

 

10.   The New Zealand Law Commission (NZLC) in its 1999 Report on Evidence referred to Professor R D Friedman's reasons for reforming the hearsay rule:[10]

 

"The [rule against hearsay] excludes much evidence that is helpful to the truth determining process; it fails to identify that hearsay which should be excluded to protect the fundamental rights of a criminal defendant; it creates unnecessary costs, as parties must arrange for the testimony of witnesses in situations where secondary evidence would suffice; it confuses judges, lawyers, and students; and it creates contempt for evidentiary law, because it fails to reflect values for which most people have respect, and so often it is ignored in practice ¡K [H]earsay law, where it exists, should be radically transformed and liberalised."

 

 

Is Hong Kong exceptional?

 

4.3                   Despite all these comments and this history, the suggestion was made at an early stage of our deliberations that there was in Hong Kong no difficulty with the application of the hearsay rule.  We were told that the Law Society¡¦s Criminal Law and Procedure Committee saw no need for reform, this at a stage when none of the issues had been studied by them.  It was suggested, too, that the Bar should be consulted about the need for reform at the outset of our deliberations.  The majority of the committee thought this premature and that it would be better for the profession to comment after, rather than before, a study.  It was suggested that the problem here was minimised by the fact that most cases were tried by magistrates who, where the interests of justice so required, paid little attention to the rule.  The suggestion was further made that there was no evidence that any injustice had been occasioned to defendants in Hong Kong by reason of the hearsay rule and, specifically, by reason of exclusion of third-party confessions.

 

4.4           The suggestion that the hearsay rule provides no difficulties in Hong Kong is to suggest that the longstanding difficulties of the hearsay rule recognised throughout the common law world are, for some undefined reason, managed here with an ease that the rest of the world finds difficult to achieve, and that the illogicalities to which we will later refer in detail in this report are of no significance in Hong Kong.  No reason is put forward for this ability supposedly unique to Hong Kong, save the suggestion that most of our trials are not before juries.  Our research has shown that in all jurisdictions where there has been a call for reform, a large percentage of trials take place before tribunals without juries; and further, the suggestion assumes that in cases before professional tribunals the rules somehow lose their irrational aspects and their potential for injustice.  In any event, juries try the most serious cases.  The fact that numerically most of the cases are tried by the lower courts will be of little comfort to the High Court defendant who wishes to adduce helpful and reliable evidence, or to the public interest in seeing effective prosecutions based on reliable evidence in serious cases.  If indeed magistrates or judges sitting alone adopt a loose approach to the rule to ensure that the justice of the matter is met, then the law is demonstrably deficient, for it means that the gaps are being addressed not by law reform but by ignoring the law. 

 

4.5           The problem with hearsay is not only a problem of understanding the basic rules and their application.  The rule and its exceptions are well recognised as unusually complex.  The difficulties which have resulted in reform across the common law world have not been driven solely, or even mainly, by questions of comprehension.  There are more fundamental problems to which this paper refers in detail; and which apply to trials at all levels.  The further suggestion that there is no need for reform because no one can pinpoint an example of a miscarriage of justice in Hong Kong is a suggestion which misses the point of principle.  That a miscarriage of justice can result from the non-production of reliable evidence is self evident; and it is also self evident that our present laws preclude in certain instances the admission of reliable cogent evidence.  We do not think society should wait for an actual miscarriage of justice in Hong Kong before starting upon the road to prevent one.  

 

4.6           Concerns were also expressed that the object of this reform exercise may be to secure the conviction of more people; or to strengthen the hand of prosecutors.  We are in no doubt that this was not what triggered the reference by the Commission.  Our terms of reference are to ascertain whether the law was in need of reform and, if so, what reform should be effected in the interests both of defendants, and of the proper prosecution of cases, where such reform is demanded and is justifiable and is hedged about by proper safeguards.  It should be borne in mind that one of the key motivations for reform in all the common law jurisdictions which have examined the problem is the protection of the innocent.  Comfort might also be drawn from the fact that the jurisdictions which have been engaged in these exercises have impeccable credentials when it comes to ensuring the protection of the innocent.

 

 

Principles of reform and the identification of shortcomings

 

4.7           We have identified a number of cardinal principles which should apply to all evidence rules, including the hearsay rule.  These cardinal principles are as follows:

 

1.         Evidentiary rules should, within the limits of justice and fairness to all parties, facilitate and not hinder the determination of relevant issues.

2.         Conviction of the innocent is always to be avoided.  All accused have a fundamental right to make full answer and defence to a criminal charge.

3.         Evidentiary rules should be clear, simple, accessible, and easily understood.

4.         Evidentiary rules should be logical, consistent, and based on principled reasons.

5.         Questions of admissibility should be determinable with a fair degree of certainty prior to trial so that the legal adviser may properly advise the client on the likely trial outcome.

6.         Evidence law should reflect increasing global mobility and modern advancements in electronic communications.

 

 

Shortcomings

 

4.8           We have tested the existing law against each of these cardinal principles.  Members concluded that under each of these principles, the present rule exhibited shortcomings, some of greater consequence than others.

 

4.9           We have been conscious throughout our deliberations of the necessity to keep in mind the advantages of, and the original rationale for, the hearsay rule:  the great importance of the right to challenge the accuracy of evidence, for the exercise of which the ability to confront and cross examine a witness is a key consideration.  So, too, confrontation is said to be salutary to the witness and also gives to the proceedings, and to an accused, a sense of justice being seen to be done.  Amongst other dangers of admitting hearsay is the risk that a trier of fact might place too much weight on hearsay; the risk of misunderstanding by the witness hearing the declaration; the risk of fabrication by the witness; the risk of faulty memory of the witness; the risk of misperception by the witness.

 

 

(1)   Evidentiary rules should, within the limits of justice and fairness to all parties, facilitate and not hinder the determination of relevant issues

 

4.10                The present hearsay rules do not assist, and in some instances they hinder, the determination of relevant issues.  A primary criticism of the present law in criminal proceedings is that the exceptions to the exclusionary rule are too restrictive and narrow in scope.  As a result, evidence which is otherwise cogent and reliable is excluded from consideration.

 

4.11                While the exceptions go some way to mitigate the harsh consequences of the hearsay rule, they provide only a partial solution.  The effect of the rule is to exclude evidence because of its characteristics, without regard to whether or not it is reliable.  A legal framework which emphasises reliability, rather than the nature of the evidence would seem more in tune with the aim of determining fairly the guilt or innocence of the accused.

 

4.12                One area in which the hearsay rule arguably excludes cogent evidence is in respect of implied assertions.  In R v Kearley[11], the House of Lords ruled that evidence of telephone calls to the accused from persons inquiring as to the supply of drugs was inadmissible, as evidence of the calls would amount to an implied assertion that the accused was a supplier of drugs.  The House ruled that an implied assertion was hearsay (and thus inadmissible) in the same way as evidence from an express assertion.  The Hong Kong Court of Appeal reached the same conclusion in R v Ng Kin‑yee[12] in respect of telephone calls making inquiries about bookmaking.

 

4.13                The justification for excluding implied assertions from the court's consideration is that there exists no logical distinction between an "implied assertion" and one that is express.  An inference of guilt from an implied assertion would be as dangerous as one drawn from an express assertion made by a person who is not in court to testify.  However, this overlooks the fundamental distinction that implied assertions concern the conduct of persons who do not intend to make the assertion in question.  For example, in Kearley, none of the callers intended to convey the message that the defendant was a supplier of drugs.  Indeed, it was the unintended and genuine nature of their conduct that gave this evidence considerable probative force.  Unfortunately, the rule excluding implied assertions is heavily formalistic and unable to give effect to the substance of the evidence.

 

4.14                Despite common roots, the rule has been interpreted differently in Australia.  For example, in Firman[13], the Supreme Court of South Australia held that telephone calls consisting of inquiries for drugs by potential customers were relevant as they tended to prove the existence of an illegal activity and the accused's involvement in it.  The court held that:

 

"The making of such inquiries and offers by a number of people tends to prove the carrying on of a business.  If such inquiries or offers are directed to a particular premises, they tend to prove the carrying on of the business at those premises.  If they are directed to a particular person they tend to prove the carrying on of the business by that person."

 

4.15                The English Law Commission's 1997 Report had this to say:

 

"Where there is an implied assertion, a fact not explicitly asserted is inferred from words or conduct which may or may not themselves be an assertion:  for example, they may take the form of a question, or a greeting.  In ordinary life it is common for a fact to be inferred from the fact that a person is behaving as if it were true.  If this reasoning is not permitted, it follows that much relevant evidence is excluded.[14]"

 

4.16                Triers of fact are routinely required to assess the weight to be placed upon different portions of the evidence tendered during a trial: there seems to be no reason, in logic, why they could not be entrusted with performing such an exercise with evidence of this nature.  That said, the Sub-committee acknowledges that sight should never be lost of the risk in admitting relevant but untested hearsay evidence.

 

4.17                The decision in R v Harry[15] provides another example of how justice can be sabotaged by the strict application of the hearsay rule.  The defence wished to cross-examine a prosecution witness about certain telephone calls which were made to the flat in which the accused and his co-accused lived and in which a large quantity of cocaine was found.  The reason for cross-examining the witness was to show that the co-accused was in fact the drug dealer as the great majority of the calls were for the co-­accused and that those calls were about the prospective sales of cocaine.  It was held that the defence should not be permitted to cross-examine the witness as the purpose of the cross-examination was to prove in a hearsay way that the co-accused, and not the accused, was in fact the drug dealer.

 

4.18                Similarly in R v Yick Hin-tong[16], the Benefit Investment Company was held to have been the publisher of certain books on the basis that the company's name was printed on those books.  On appeal, it was held that the magistrate had erred in relying on what was printed on the books.  In allowing the appeal, O'Connor J expressed his frustration with the law and said:

 

"The evidence that the books carried in print the information that Benefit Investment Co was the printer, being an assertion made otherwise than by a witness in court, and not being within an exception to the hearsay rule, was not admissible as to the truth of the matter asserted, that Benefit Investment Co was the printer. That conclusion is not in accord with everyday experience, nor has it anything in common with common sense. Nevertheless, it is the law, and on that ground, the appeals on charges A, C, D and E will be allowed."[17]

 

4.19                A commonplace demonstration of the absurdity of the present hearsay rule is that a person cannot give evidence of his own age, because he does not know when he was born; someone else must have told him.  As Kaufman JA in R v La Chapelle[18] noted: "If it is hearsay for a person to testify as to his own date of birth, the same reasoning would exclude him from testifying as to the identity of his own parents.".

 

 

(2)   Conviction of the innocent is always to be avoided.  All accused have a fundamental right to make full answer and defence to a criminal charge

 

4.20                Perhaps the weightiest criticism of the hearsay rule is its inability to yield for evidence that might exculpate an innocent person wrongly accused of a serious offence.  The case of Sparks v Regina is a classic example.[19]  In this case, the three-year old victim girl, who was too young to testify, told her mother shortly after the incident that the person who molested her was a ¡§coloured boy¡¨.  The statement was inadmissible even though the statement probably would have exculpated Sparks, a white American Air Force staff sergeant. 

 

4.21             R v Blastland is another classic example.[20]   The accused was alleged to have killed a young boy.  There were, however, a number of persons who were prepared to testify that shortly after the killing of the young boy another person known as "M" had told them that a young boy had been murdered.  The circumstances were such that M's knowledge of the killing raised an inference that he had himself committed the murder.  The trial judge ruled that as the purpose of calling the witnesses was to prove by inference that it was M who had committed the crime, the evidence had to be rejected as it was hearsay and inadmissible.

 

4.22                The English Law Commission referred to the decision in Blastland in their 1997 Report and remarked:

 

"... if the evidence shows that there is a possibility that someone else committed the crime alone, and the jury cannot dismiss that possibility, then they cannot be sure of the accused's guilt, and therefore should not convict.  The fact that someone else has confessed to the offence is logically relevant to the issue of whether the defendant committed it: this is so whether the other person is a co-defendant who gives evidence, a co-defendant who exercises the right not to give evidence, a co-defendant who is tried separately, or a person who is never caught or never prosecuted.  Moreover, it will normally be impossible for a defendant to adduce the oral evidence of the person who has confessed, because that person could rely on the privilege against self incrimination. "[21]

 

4.23                Wigmore[22] described this aspect of the hearsay rule as a "barbarous doctrine".  In England, it appears that, in practice, the problem presented in Blastland can be solved by both parties agreeing to admit the hearsay statement (see the recent case of R v Greenwood[23]).  However, such a solution is technically not possible under the present Hong Kong laws (see paragraphs 9.28 and 9.29 below for a discussion of this problem).

 

4.24                Whilst recognizing the increased possibility of fabrication in circumstances such as those in Blastland, depriving an accused of the right to adduce evidence of third-party confessions arguably may constitute an erosion of his fundamental right to make full answer and defence to a criminal charge.

 

4.25                Another example, though less well known than the previous two, is the startling case of R v Schwarz, considered by the South Australian Supreme Court.[24]  The appellant was charged with murder.  The immediate cause of the deceased¡¦s death was tetanus but the prosecution alleged that the accused had caused death by wounding him in the foot with a garden fork, thereby introducing tetanus germs into his body.  The deceased died 11 days after he received the wounds.  The doctor who attended the deceased the day after the incident was called as a witness by the Crown.  He was asked by counsel for the accused ¡§Did deceased tell you anything on that occasion as to how the wounds were caused?¡¨[25]  The prosecution objected to this question on the basis that it would generate a statement by the deceased which was hearsay.  The South Australian Full Court examined the law in some depth and concluded that: (1) the statement could not be part of the res gestae as it was not made during or immediately after the commission of the offence, but the next day: (2) the statement was not made in the presence of the accused: (3) the statement could not be a dying declaration because after the deceased had been stabbed in the foot he certainly had no belief that he would some ten days later die from infection: (4) there was no possibility that the statement was made by the deceased in the course of duty and in the ordinary course of business: and (5) it was argued that the statement was made by the deceased person and was wholly or in part against his pecuniary or proprietary interests.  The judgment turns on that issue.

 

4.26                The South Australian Full Court ruled that the statement was wholly inadmissible.  An additional part of the evidence also ruled inadmissible was what the doctor said to the following effect:

 

¡§He (the deceased) told me that he came out of this place and hit Schwarz twice with a stick over the head, that Schwarz ran away, that he took up the fork as he was running and threw it behind him towards the deceased, but he was sure Schwarz did not intend to injure him and he hoped Schwarz would not get into any trouble with the Police over it as it was not his fault¡¨.

 

4.27                This extraordinarily important and valuable evidence given by the deceased was ruled to be inadmissible on the murder trial as it did not fit any recognised category of admissibility as an exception to the hearsay rule.  That decision was affirmed by the South Australian Full Court.

 

4.28                In Hong Kong, there is at least one reported case in which injustice akin to that seen in Blastland, Sparks and Schwarz, almost resulted.  In HKSAR v Au Yuen-mei (No 2), the accused and her husband were charged with drug trafficking offences.[26]  On arraignment, the husband pleaded guilty.  At the accused¡¦s trial, the court had to consider whether the husband¡¦s statement admitting to forcing the accused to carry the drugs was admissible.  The court ultimately admitted the statement by extending the principles set down in R v Myers.[27]  It awaits to be seen if the decision will be upheld by higher authority but clearly the court was trying to avoid an injustice wrought by the inflexible hearsay rule.

 

4.29                There are many other cases in which cogent defence evidence has been excluded by the hearsay rule.  Some of these include:

 

Ø  R v Harry:[28]  telephone calls from drug buyers asking for the co-accused could not be adduced by the accused, who was charged together with the co-accused with drug trafficking offences.

 

Ø  R v Thomson:[29]  defendant, who was charged with procuring an illegal abortion, was not allowed to adduce evidence that the pregnant woman (now deceased) had stated that she had performed the operation by herself.

 

Ø  The Queen v Chow Ching-fuk:[30]  accused and his brother were charged with joint possession of morphine for the purposes of trafficking; brother¡¦s statement exculpating accused made when caught red-handed with the drugs could not be admitted in the accused¡¦s defence.

 

Ø  The Queen v Yiu Man-chung:[31]  accused and co-accused were passenger and driver, respectively, in a car stopped by the police; one knife was found under the driver¡¦s seat, another under the passenger¡¦s seat; co-accused¡¦s statement claiming that both knives were his own inadmissible at trial, at which co-accused failed to appear.

 

 

(3)   Evidentiary rules should be clear, simple, accessible, and easily understood

 

4.30                Cross & Tapper begins the chapter on hearsay as follows:

 

"The hearsay rule has often been regarded as one of the most complex and most confusing of the exclusionary rules of evidence.  Lord Reid said that it was ¡¥difficult to make any general statement about the law of hearsay which is entirely accurate.¡¦ "[32]

 

4.31                The cumulative effect of the absurdities caused by the illogicality of the hearsay rule caused Lord Griffiths to remark in Kearley:

 

" ¡K most layman if told that the criminal law of evidence forbade them even to consider such evidence as we are debating in this appeal would reply 'Then the law is an ass'. "[33]

 

4.32                If judges and lawyers have difficulty understanding the hearsay rule, there must be doubt as to the ability of a jury to understand, and to apply properly, instructions on how to consider hearsay evidence.  However, empirical evidence of jury understanding in this regard is difficult to obtain given the secrecy of jury deliberations.  When hearsay evidence is admitted for non-hearsay purposes, the jury must be told how the evidence can and cannot be used.  Given the complexities of the hearsay rule, the danger that juries will misuse such evidence is a real one.  There are numerous situations where a jury will hear or receive evidence with the often confusing instruction that they can use the evidence for one purpose but not another.

 

4.33                The rule is often divorced from commonsense, displaying fixation with formal categorisation.  

 

4.34                The difficulty which lawyers and judges often have in applying the hearsay rule is evidence that the rule is complex and not easily understood.  Recent cases continue to illustrate how easily judges and lawyers can form different understandings of what is hearsay and how statutory exceptions should be applied.[34]  The sheer bulk of text devoted to the subject in text books on evidence is also indicative of the difficulties which the rule occasions.

 

4.35                A contributing factor to this complexity is that the law cannot be determined from a single source but must be searched out in a host of separate legislative provisions and court rulings.  The law is not easily accessible to either judge or advocate.  In addition, many of the long-standing statutory exceptions in the Hong Kong Evidence Ordinance (Cap 8) are drafted in opaque and confusing language. 

 

4.36                Courts from different common law jurisdictions have understood and applied the rule differently.  Questions as basic as the definition of hearsay have attracted extensive judicial consideration and debate. 

 

 

(4)   Evidentiary rules should be logical, consistent, and based on principled reasons

 

4.37                The most consistent objection to the admissibility of hearsay evidence emphasises the inability to test the evidence through cross-examination, the lack of opportunity to see the witness's demeanour, and the unsworn character of the statement. 

 

4.38                Thus, logically, exceptions to the hearsay rule should be based on the non-existence of one or more of these dangers.  However, this is not the case.  While for the most part the existing exceptions do operate on this basis, there are significant gaps.  Not every situation where one or more of the hearsay dangers is lacking is covered by an exception to the hearsay rule.  The exceptions themselves have been arbitrarily defined with little flexibility.  The limited scope of some exceptions often cannot be explained in terms of the rationale for the exception.

 

4.39                Phipson on Evidenc[35] postulates classification of the exceptions into five major groups of cases.  They are:

 

" ¡K (a) cases based on the axiom that what a man says against his own interest is likely to be true, (b) cases based on the intrinsic reliability of public records, (c) cases recognizing that where a witness is dead, it may be better to admit evidence of what he said than to deprive the court of all proof, (d) cases recognizing the force of common knowledge, where a fact is reputed among those who ought to know it, but its source is unknown, and (e) cases where the contemporaneity of the statement is itself some guarantee of its reliability."

 

4.40                A further problem concerns the validity of the rationale for  particular exceptions.  For instance, assumptions concerning human behaviour, on which some of the exceptions were based, may not necessarily be true or accepted today.

 

4.41                Examples of illogicalities abound:

 

1.         Refreshing memory  The practice of allowing a witness to refresh his memory from an earlier note or statement is an obvious example: the practice requires the trier of fact then to accept the evidence from the less reliable "refreshed" witness instead of receiving the more reliable contemporaneous written source used to refresh the witness. If the witness is not refreshed, the hearsay rule has no exception to receive the written statement instead.

 

2.         Declarations against interest  This exception only extends to declarations against pecuniary and proprietary interest and not to those against penal interest.  Conversely, the Supreme Court of Canada in R v O'Brien[36] extended the exception to statements against penal interest for the logical reason that: "A person is as likely to speak the truth in a matter affecting his liberty as in a matter affecting his pocketbook."[37]

 

3.         Dying declarations  This exception is arbitrarily narrow, extending only to cases of murder and manslaughter.  It is also confined to statements made under a settled and hopeless expectation of death.  A third arbitrary limitation of the rule is that the declaration can only be proof of the declarant's cause of death.  There seems to be no logical justification for these restrictions.  A further illogicality exists: a dying declaration in which the victim named his assailant would be admissible, but not a similar declaration in which a person on the verge of death confessed to his crime.

 

4.         Res gestae The spontaneous and contemporaneous conduct, opinion or statement of a person who is not available to give evidence may be admitted as evidence where the conduct, opinion or statement was so closely and inextricably bound up with the history of the guilty act itself as to form a part of a single chain of relevant evidence.  The evidence admitted may be used not only as evidence of truth but also as evidence of the person's state of mind or emotional state at the relevant moment.  Such a situation may leave little opportunity for concoction but there may exist other reliability problems as statements made in the heat of the moment may be particularly prone to distortion, perhaps unwittingly, as the perceptions of both the declarant and the testimonial witness may be coloured by the emotion of the moment.  Moreover, courts have also held that out-of­-court statements evidencing the declarant's state of mind do not come within the definition of hearsay.  This confusion obscures rather than clarifies the extent and rationale of the exception.

 

5.         Documentary and computer records   The Court of Final Appeal has criticized sections 22 and 22A of the Evidence Ordinance (Cap. 8) suggesting the need for legislative reform.[38]

 

6.         Negative assertions The English Law Commission noted the illogicality that

                                  "It seems that, if an inference is drawn from a document, it is hearsay, but if an inference is drawn from the non-existence of a document or entry, it is direct evidence." [39]

                        Negative inferences from the absence of a record are permissible, whereas positive inferences from the record are not, Shone[40].

 

7.         Evidence is admitted to prove state of mind or a belief, rather than the fact or the suggested fact to which the belief is directed  If it is rational and probative to draw the inference of fact from the state of mind (that X not only was in fear but had good reason to fear) a rule which prevents the trier of fact from doing so appears illogical.  It is then valid to consider whether, in any event and despite all directions to the contrary, it is realistic to expect that a jury will do anything else but draw the inference of fact.

 

8.         Recent complaints  If a recent complaint is to be regarded not as proof of truth of the content of the statement but only as evidence of consistency, there seems little logic (as opposed to theoretical justification) that it be so only in cases of sexual assault.  Once again, it is then valid to consider whether, in any event and despite all directions to the contrary, it is realistic to expect that a jury will do anything other than treat a recent complaint as evidence of the truth of the complaint.

 

9.         Implied assertions  Where there is no intention to assert a fact when a comment is made, the implied assertion might well be regarded as self authenticating[41].

 

10.       Previous inconsistent statements  A previous inconsistent statement is not evidence of the truth of its contents, even though on the facts of a particular case common sense might dictate that the previous statement was obviously true or more reliable than the subsequent oral evidence.

 

11.             Previous consistent statements  There is much to be said for the view that to regard previous consistent statements as going only to the issue of credibility is illogical.

 

12.             Witness¡¦s demeanour  It is now recognised that over-emphasis has been placed in the past on the demeanour of a witness testifying in court.  Demeanour can be a misleading guide to veracity.
