Double Jeopardy: Policy, Reform, and Post-Acquittal Retrials

Introduction

The ancient common-law prohibition on multiple trials, known as the double jeopardy rule, is a procedural protection that forbids the prosecution of an offender for an unlawful offence of which they have already been acquitted or convicted following a trial on the merits by a competent criminal jurisdiction. Double jeopardy arises when there has been a prior criminal trial. In many states around the world, the protection against double jeopardy is a constitutional right, while in others statute law provides for the protection. Statutory modification — the basis of the principle in England — is the framework for reforms in several common law jurisdictions that allow post-acquittal trials in limited situations (Corns, 2003).

This paper explores the policy issues for and against this protection-rule reform, the statutory modification of the principle in England, and the procedural safeguards for post-acquittal retrials. Some of the issues that emerge in the Irish criminal justice process do not portray any uniqueness concerning the subject matter; therefore, it is important to contrast and compare advancements in the various jurisdictions. The evaluations provided and the solutions suggested by the legislature and courts in England maintain their own interest, and they may often offer solutions to matters that require resolution in the Irish criminal justice process (Coffey, 2013).

Policy Considerations Underlying the Principle Against Double Jeopardy

Proponents of double jeopardy reform state that retrials would constitute a significant encroachment on the fundamental procedural rights of the accused. In many instances, an innocent individual may lack the resources to fight a second charge. Knowing that a second proceeding is likely to occur, an innocent individual may plead guilty at the first trial. In addition, if the accused opts to contest the second charge, they are at a disadvantage compared to the first trial because their defense was disclosed at the previous trial. This arises primarily because the prosecutor may study the transcript of the first proceeding, eliminating apparent inadequacies in the evidence used in the second trial.

Similarly, in Green v. United States, Black J. stated (Coffey, 2013):

Increased Risk of Wrongful Conviction

"The underlying view, one central in the Anglo-American systems of jurisprudence, is that the state, together with all its powers and resources, is forbidden to convict an individual for an offence, subjecting them to shame, embarrassment, and compelling them to live in a continuous condition of anxiety and insecurity, while enhancing the possibility that, although they are innocent, the state may find them guilty."

Post-acquittal retrials augment the threat of wrongful conviction in instances where the prosecution offers a weak case. Most defendants, having already endured a lengthy and demanding trial, may lack the resources needed to mount a strong defense at a retrial. In such a scenario, the prosecution has a tactical advantage at the retrial because the defense case is apparent and prosecution strategies can be modified accordingly. There is also a high probability that a jury may convict the accused unfairly (Parkinson, 2003).

These existing advantages make it easier to discharge the burden of proof and highlight the need for judicial vigilance when considering applications based on statutory exclusions to the principle. There is therefore a need to discourage post-acquittal retrials unless there is fresh and compelling evidence, as the procedural challenges associated with such applications reduce the threat of wrongful convictions when hearing a matter for the second time. Furthermore, undesirable pre-trial publicity can undermine the impartiality of the trial process, since the jury may be influenced by adverse coverage in print media, electronic media, and the internet.

Publicity associated with a retrial, particularly where compelling evidence of guilt is involved, might lead to an unfair retrial. This jeopardizes the defendant's fundamental rights during the retrial process. Courts must therefore consider the effect of adverse pre-trial publicity and whether it is appropriate to proceed with a criminal trial until the effects of such publicity have faded from the memories of prospective jurors (Ruva, McEvoy, & Bryant, 2007). The necessity for reporting restrictions is significant in the case of a retrial following the quashing of an acquittal, as outlined in the statutory exceptions to the prohibition on double jeopardy.
