Can investigative processes produce miscarriages of justice?
by Neville Trendle
Former Chief Legal Adviser and Assistant Commissioner
New Zealand Police

In the years since Judge Learned Hand's reassurance as to the robustness of the institutions of justice, [01] we have come to acknowledge that our criminal justice system is fallible. Despite highly developed rules and procedures to protect the innocent, miscarriages of justice do occur.

When considering how and why they occur, the investigation phase provides an obvious starting point. It is the evidence-gathering stage when relevant and irrelevant material is gathered and assembled; where the relevant material is sifted and organised; and where it is then collated and presented in the form of a prosecution case. The processes followed largely determine what material is gathered and how it is collected. During the course of the investigation, decisions and judgments are made and action taken that may have significant implications later on.

Inquiries into individual cases of wrongful conviction have identified investigative processes which have led to a miscarriage of justice in the particular case. And studies over many years have pointed to common features that consistently arise in wrongful conviction cases. Most of this knowledge is derived from overseas. Though there is very limited empirical information to draw on from experience in New Zealand, there is no reason to think that the same issues are not relevant here. Indeed, individual cases of wrongful conviction here reflect a similar pattern of shortcomings.

While in some cases it may be right to assert that responsibility for a miscarriage of justice fell on the investigating officers [02] generally, the reasons lie far deeper. The frequent use of expressions in the research and inquiries such as "systemic problems', or "systemic failure" point to a link between investigative processes and miscarriages of justice.   And often, individual failings are a reflection of weaknesses in the process.

This paper will discuss those investigative processes which have been identified as contributing to miscarriages of justice; it will also note a number of environmental factors that consistently feature in reviews of wrongful convictions; and it will suggest that whilst there is merit in looking at options for remedying miscarriages of justice in New Zealand, there is much to be gained by developing investigative processes in a number of identifiable risk areas with a view to reducing the potential for miscarriages to occur.

 

Miscarriages of Justice and Investigative Processes

It is first necessary to briefly describe what is meant by the expressions "miscarriage of justice" and "investigative processes" for the purposes of this paper.

In the course of his examination of the significance of miscarriages of justice, both generally and in the New Zealand context, Sir Thomas Thorp adopted the primary meaning of the term as "an unjustified conviction." [03] That approach is also taken in this paper; but whilst we are principally concerned with the wrongful conviction of an innocent accused, it will be suggested that it is equally as important to keep in mind that the acquittal of a factually guilty accused due to the fallibility of investigative processes, also results in a miscarriage of justice. [04]   The potential for justice to be compromised also arises when a guilty accused escapes conviction: "the criminal is to go free because the constable has blundered." [05]

The term "investigative processes" includes all the various components of a police inquiry into serious crime from the time it is reported until the time an arrest is made. It is not confined to strictly investigative functions and also extends to those processes that occur between arrest and trial, including the prosecution disclosure process. Whilst it encompasses the role of external experts, only passing reference will be made to the contribution made by forensic science which is a topic dealt with elsewhere.

 

Criminal investigation processes

Serious crime investigations can be particularly complex. High levels of skill are required to manage the investigation, when information that is rapidly accumulating from a number of sources may be conflicting, ambiguous, or reveal only half the story. Effective interaction with the victim, witnesses and suspects is vital to produce a complete, accurate and concise record. Rigorous procedures for crime scene examinations, securing of exhibits and documenting the investigative effort are essential. And both the processes and the investigators who implement them must be able to adapt as the investigation unfolds.

Investigative processes are not confined to activities performed solely by police officers. External expertise is invariably involved in any significant investigation. The interface between the internal investigative effort and that provided by external experts or advisers is critical in two respects. First, the preliminary work done by investigators may impact on the quality of the input provided by the expert; for example the preservation and searching of a crime scene may directly affect the result of the forensic scientist's analysis. Secondly, the provision of objective opinions and free and frank advice by experts to the investigators is vital. The skills and expertise of an external expert also provides the opportunity for a different perspective to be brought to bear and for views to be expressed that may differ from those held by the investigator. This can be an antidote to tunnel vision, an issue to be discussed later.

Every investigation into a serious crime is different. There are, however, a number of relatively common elements that collectively provide a framework for significant investigations. These elements can be identified as:

·                The victim

·                Witnesses

·                The scene

·                Suspects

·                Intelligence and analysis

Not all these elements will be necessarily present in every case, but they are likely to be found in most serious crime investigations. Within each of these elements are processes that have the potential to contribute to a miscarriage of justice.

The victim is invariably a critical source of information and usually the starting point for an investigation. Yet there are instances where the victim has been honestly mistaken with identification evidence and false or fictitious complaints are not unknown. Eyewitnesses may also be mistaken in recounting their recollection of events and a witness with a motive for doing so may deliberately provide false information. The scene and more particularly, scene examinations have become increasingly important feature of major investigations, yet inadvertent contamination of the scene or exhibits, or even the deliberate "planting" of evidence may lead to a wrongful conviction. And finally there is the potential for intelligence sources, particularly criminal witnesses, or the faulty analysis of available evidence, to contribute directly or indirectly to a wrongful conviction.

 

Investigative processes as causes of error

It is uncommon for a wrongful conviction to arise from single error. Studies and inquiries have generally identified a combination of factors as causing of a miscarriage of justice. And those causes may be often be attributable in part to investigative processes and in part to the trial process. So far as the former is concerned, six specific areas have consistently been identified as significant contributors to wrongful convictions. Each of these will be briefly discussed. [06]

 

Eyewitness Identification

The notorious uncertainty of identification and the fact that wrongful convictions have resulted following incorrect eyewitness identifications has been acknowledged by the highest courts.[07] Witness misidentification is said to be the single most important factor leading to wrongful convictions. [08]

In individual cases, the judicial scrutiny of identifications arising from circumstances that tend to increase the risk of misidentification often result in the evidence being ruled inadmissible. [09] And over many years identification procedures have been reviewed and legislative and operational changes made to address the risks inherent in this evidence. [10] The various ways in which an eyewitness's identification may become tainted were most recently highlighted by the Sophonow Inquiry in Canada revealing in particular the potential for investigative procedures to contribute to misidentification and leading the Inquiry Commissioner to advance a number of recommendations in line-up and photographic display procedures. [11]

The potential for eyewitnesses misidentification is ever present. It is an area where the protection offered by the law and by judicial oversight of the fairness of police identification procedures [12] can never guarantee freedom from error. [13] The refining of identification processes is an ongoing responsibility.

 

Disclosure

Incomplete disclosure by the prosecution has been identified as a significant factor contributing to a miscarriage of justice in several inquiries. [14] Whilst on its face, the prosecution's duty to disclose relevant material to the defence should be a straight forward matter the difficulty often lies in determining what is "relevant." The various guidelines developed to assist in that regard have had to achieve a balance on the one hand between full and proper disclosure of the prosecution case including material that detracts from it or that may assist the defence, and on the other excluding material that is of no relevance at all in the case and would be unduly burdensome to require the prosecution to provide. [15]

In New Zealand the burden of prosecution disclosure is often discharged at least initially by the investigator.    There can be obvious difficulty in an investigator who is charged with piecing together a prosecution case, making a judgment as to material that may detract from that case and from identifying material of relevance to the defence when the investigator may, at that stage, have little idea of what is relevant. The ongoing nature of the disclosure duty can also produce a further difficulty, for unless the investigator is fully imbued with the philosophy of prosecution disclosure, a notion that is not usually instinctive, the identification of material on the investigation file that later becomes relevant for disclosure purposes may not be pointed out to the prosecutor. The disclosure of an important job sheet or statement may fall through the cracks; the prosecutor is quite unaware of its existence and the investigator overlooks or fails to mention it.

The existence of a parallel disclosure process through the Official Information Act 1982 has occasionally served to bring to light cases of incomplete prosecution disclosure. [16] Recommendations to better prescribe and codify the prosecution's duty seem shortly to bear fruit. [17]

 

False complaints

False allegations to the Police that a crime has been committed are not uncommon. They range from insurance fraud to complaints of sexual offending. A significant number of false complaints are investigated each year and prosecutions result. [18] Wrongful convictions arising from a victim's false complaint are relatively rare, but not unknown in New Zealand. [19]

Dealing with a possible false complaint is no easy matter. Victims are often frightened, embarrassed and distressed when they complain and this may affect their immediate recollection of events. Relevant details can be missed; there may be inconsistencies in their account of what happened. And even later, there is a very delicate balance between the appropriate exploration of inconsistencies and doubting the genuineness of the victim's complaint. This is ultimately an area where time and the checks and balances in both investigative and trial processes generally work effectively to reduce the risks of wrongful conviction arising from a false complaint.

 

False confessions

False confessions comprise a significant number of cases of wrongful convictions, at least in the United Kingdom. [20]   Whereas years ago, confessions that were the product of violence or coercion would not have been regarded as remarkable, improvements in interviewing processes have contributed to significantly reduce their occurrence. Nevertheless, a body of literature has documented hundreds of examples where confessions have subsequently proved to be false. [21]   Many were voluntarily, but most were the result of the suspect's response to various interview techniques adopted by the police. [22]

Though the common law rules relating to confessions are directed principally towards ensuring their voluntariness, the rules are also concerned with reliability. Thus, there have been some cases instances in New Zealand where convictions based on voluntary confessions were subsequently set aside. [23] The introduction of video recording of suspect interviews has significantly reduced the occasions when the resulting statement has been successfully challenged. But the electronic recording of by itself cannot provide absolute protection against false confessions. Ultimately this is an area where the in vestment in police training and professional development is likely to be amply repaid.

 

Inmate witnesses

Witnesses with criminal backgrounds frequently give evidence in criminal trials. "Jailhouse informants", or inmate witnesses form a particular group of witnesses with a criminal background who have featured in cases where wrongful convictions have occurred. The dangers in the evidence of inmate witnesses are obvious.   Their criminal record often qualifies them as a potentially unreliable witness; where they are facing serious charges, or long terms of imprisonment, they may be motivated by the prospect of personal benefit or favourable treatment in return for their evidence; the testimony they typically give relating to unwitnessed conversations they had with the accused (which usually includes a confession) is easy to concoct and hard to refute.

Whilst there is no rule excluding the testimony of inmate witnesses, their evidence is invariably the subject of a strong warning to the jury as to its inherent unreliability. [24] Inquiries into miscarriages of justice have also highlighted the dangers of such evidence and the Morin Inquiry in Canada in particular, devoted a substantial part of its report to recommendations that such evidence be subjected to a higher level of scrutiny and process. [25]

The use of inmate witnesses (sometimes labeled in the media as "secret witnesses") is relatively infrequent in New Zealand and they are generally only called after their evidence has been carefully evaluated in the light of the experience with such testimony. [26]  Nevertheless this evaluation takes place on a case-by-case basis and no formal policy with respect to the evidence of inmate witnesses has been developed to date.

 

Police mishandling of case

This generic heading encompasses a range of situations of which only a brief account is possible here. The mishandling may be a simple error arising from the inadvertent failure to observe standard investigative processes discussed above, or it may arise through deliberate misconduct, or criminal offending. [27] In some instances of miscarriages of justice, illegality or breaches of standard procedures reflect not just a lack of individual competence, but also a wider cultural malaise within the investigation team. [28] The "bending" of rules, corner cutting and other unprofessional conduct by investigators on the pretext that such actions are necessary to achieve the expected result is an issue that every police organisation has to grapple with. Investigating crime has aptly been described as a competitive business. Whilst it may seem an ideal, developing and maintaining a culture where deliberate breaches of process are simply not tolerated and adherence to high ethical standards of professionalism is encouraged, is critical. The slippery slope to "noble cause" corruption is never far away.

Another issue under this heading which has emerged as a factor in miscarriage of justice cases is tunnel vision on the part of the investigators. "Tunnel vision" results in the investigator focusing on a particular suspect or line of inquiry, to the exclusion of others that should be investigated. It was identified in each of the Canadian inquiries as directly contributing to the wrongful conviction of the accused. [29] In one report it was described as "insidious" and a virus that could affect anyone associated with the case. [30] There is often a fine line between a determination to keep an investigation on track and tunnel vision.     A judgment call as to whether a particular line of inquiry should be pursued as relevant to the investigation when a suspect has been identified is often called for. But a mindset that is focused on only one possibility and refuses to consider others is to be avoided.

 

Environmental influences

Serious crime investigations, like their resulting trials, attract public interest. They also take place in an environment that reflects the social and political times and the community in which they occur. A number of influences shape this environment. First, there are a number that are internal to the police investigation team. These include the availability of resources (they are rarely sufficient), the expectations of senior staff as to the progress of inquiries and the police culture in which the investigators operate (is it a professional culture that encourages thoroughness, adherence to investigation patterns a commitment to due process; or is it one that accepts corner-cutting and expediency based on an "end justifies the means" approach.)

External influences can be even more powerful. Where there is a victim, his or her expectations of the investigators and those of the victim's family can be a source of energy and commitment, or they can be a distraction.   Public reaction to the offence, particularly where the circumstances raise fears for community safety, creates pressure for an early arrest. Media interest is invariably intense. This can be a positive factor in terms of generating public awareness, prompting witnesses to come forward, or it can be disruptive and potentially compromising of fair trial values if journalists in a competitive news environment push the boundaries of fair reporting, or become "armchair detectives" seeking out their own witnesses and suspects. If a suspected offender has been identified, the public's attitude to the suspect can also generate pressure on the investigators to make a speedy arrest and lead to possible future implications for a fair trial. Finally, time is invariably a critical factor. Delay can result in lines of inquiry drying up and evidence deteriorating as well as sapping the energy of the investigators and public confidence in the investigation process.

The impact of environmental influences on a serious crime investigation cannot be underestimated.   They are often critical to understanding why wrongful convictions occur.   Individually they can be managed. In combination they can operate to place intense pressure on investigators and create risks for the integrity of investigative processes. Many of the most notorious cases which resulted in the conviction of an innocent person occurred when the pressures of the environmental factors led to due process standards being compromised. It is no coincidence that in each of these cases it was some years later, when the environmental influences ceased to be a factor, that the miscarriage of justice was exposed and the innocence of the convicted person was accepted. [31]

 

Developing investigative processes

There can be no doubt that mistakes made in the course of serious crime inquires have been the cause of, or at least contributed to miscarriages of justice in the past. Those mistakes can be attributed to both weaknesses in the processes themselves, and to the human failings in their execution. While we can learn from these mistakes and enhance the processes and the skills of the investigator and others, the "ghost of the innocent man convicted" is likely to remain with us. Realistically, we can reduce the odds of wrongful convictions occurring, but we are unlikely to achieve the virtual infallibility of the criminal justice system that pervaded perceptions of Learned Hand's time. [32]

While there is undoubtedly a need to consider remedial mechanisms as part of the strategy to respond to potential miscarriages of justice when they arise, there is arguably even greater benefit to be gained by focusing on investigative processes.

In doing that we should not confine ourselves to the lessons learnt from cases where a wrongful conviction has resulted. There is as much to be learned from the mistakes made

which result in the acquittal of guilty accused. The errors generally arise from the same processes and, of course, there are more of them. Furthermore, considering the mistakes made in the broader sense of the term "miscarriages of justice" provides the opportunity to do so in the context of generally improving the quality of investigative process and skills; improving them should also reduce the incidence wrongful convictions.

There are undoubtedly a number of ways in which that might be achieved. Potential lies in at least the following areas:

·                The legal framework and rules relating to those investigative processes from which miscarriages of justice most commonly occur need to kept under review. For example, identification procedures have, to some extent, been enhanced by both legislative changes and judicial rulings. Disclosure processes are shortly to become standardised through the proposals contained in the Criminal Procedure Bill 2004. And codification of the rules of evidence seems closer. It is vital that the legal framework within which investigative processes operate is not just kept up to date, but that it also reflects the delicate balance between the rights of the individual and the operational needs of law enforcement.

·                The continuous development of police investigative processes is critical. We have seen this in areas such as the video interviewing of suspects and crime scene searching and other developments are in contemplation.   Opportunities to incorporate or adapt overseas best practice have never been greater with a growing international willingness to share information.   Areas such as victim, witness and suspect interviewing and the creation of a bank of quality operational plans that can be made electronically available when required are potential possibilities.   Another area where processes have been recently reviewed in overseas jurisdictions concerns the use of evidence of inmates as witnesses.

·                The effectiveness of improved investigative processes can be diluted without a corresponding development in the skill levels of police officers and others responsible for implementing them. In the past, improved crime scene management was reflected in the deployment of specialist scene of crime officers. The relentless progress of technology in the forensic sciences will increase the demands for even higher levels of knowledge and skill in this and in other areas..

·                Associated with both these is the ongoing necessity to foster a healthy and professional police culture towards the processes associated with serious crime investigations. In one sense this poses a challenge. The time and training commitments required of a police officer to become a detective, for example, can be an obstacle to increasing the pool of qualified staff. Other possible strategies such as developing investigators in discrete areas of the investigative function such as the interviewing of suspects and informant handling may complement the skills of the generalist. Even more importantly, ongoing attention to ethics and integrity issues is central to maintaining the type of culture that reduces the risks of miscarriages of justice occurring.

·                The handling of environmental factors will continue to be a challenge. The impact of the influences discussed above on investigative processes and their potential for contributing to wrongful convictions will not diminish. The community's reaction to serious crime and its perception of law and order issues is unlikely to change. Nor is the media's response to serious crime investigations. An awareness of these influences and the continuous professional development of police leaders to recognise and manage them may be all that can be expected.

·                Refinement of processes associated with the investigation function offers perhaps the greatest potential to reduce the risks of miscarriages of justice occurring. The objectivity and independence of the prosecutor is one of the institutional safeguards in our system. Yet in overseas inquiries and studies that safeguard has occasionally been shown not to have operated to prevent a wrongful conviction, when in hindsight it should have. [33]   Strengthening processes to facilitate the prosecutor's role has benefits for both investigative processes and the trial process. Two current developments provide an opportunity to improve that interface. First, the enactment of a disclosure regime will provide a foundation for the more consistent discharge of the prosecution's obligation. [34] Secondly, improvements hi pre-trial processes recently proposed by the Law Commission [35] offer a framework for better decision making at a critical stage of a criminal investigation.

Maintaining the efficacy and integrity of investigative processes is no easy task. Inquiries into miscarriages of justice have consistently identified weaknesses that have contributed to or caused the wrongful conviction of an innocent accused. There is much to be gained, it is suggested, by strengthening those processes where we can. The context for doing so, however, should not be confined by reference only to those cases; it should incorporate the lessons to be learned from those instances that result in the acquittal of the factually guilty as well.
