Assess the value of lay decision-making in the criminal justice system by reference to the role of the jury and Justices of the Peace.

What is Jury?

The jury has been an integral part of our legal system since at least the 13th century if not, as some commentators suggest, for nearly a thousand years.  Many regard it as the institution which best expresses the philosophy of the English legal system.  The concept of the jury excites great passions, both among its supporters and its critics.  

The jury is concerned only with questions of fact.  It is never concerned with questions of law. Currently in most criminal cases the charge is first considered by a grand jury with between 12 and 23 members.  

Fine-tuning Jury’s qualification

The Criminal Justice Act 2003 also amended the Juries Act 1974 by abolishing certain categories of ineligibility (excluding mental disorder), and excusal as of right.  The bar on judges, clergy, etc is lifted. MPs, etc are no longer entitled to refuse to serve.  These groups now must do jury service unless they can show good reason not to do.  They only limitation now is disqualified and mentally disordered individuals: no-one is excused as of right.

Pros and Cons of Jury

Jury has been variously described as the safeguard of liberty; an essential check upon unpopular laws; the best means for establishing truth.  Equally enthusiastically, opponents complain that the jury has never provided any protection against oppressive government; it sometimes shows a willful disregard for the law; it lacks practical expertise; and it introduces as much prejudice as good sense into its decisions.

The value of juries in civil trials is disputed in the UK.  Opponents of juries argue that they are ineffective, irrational and cause delay; proponents argue that juries bring community standards to bear, can moderate the effects of harsh laws, and are a protection against incompetent judges.  Although the use of juries is declining for various reasons, common-law countries have a clear symbolic regard for the jury and show great care in the selection of jurors.

The strengths or weaknesses of the jury system are very much a matter of perception.  Forming an objective view upon the competence of laypersons to understand and apply legal principles appropriately is made more difficult by the existence of s8 Contempt of Court Act 1981 which prohibits any research into jury deliberations.  On that basis there is no way of discovering precisely why jurors have reached the verdict they have in a specific case or whether they have understood the legal issues and applied the law as directed by the judge.

Those who oppose the use of the jury in criminal cases suggest that these verdicts were perverse, and provide ammunition to their demands that trial by jury be phased out.  One major problem in identifying perverse verdicts is the existence of s8 Contempt of Court Act 1981: “It is a contempt of court to obtain, disclose or solicit any particulars of statement made, opinions expressed, arguments advanced or votes cast by members of a jury in the course of their deliberations in any legal proceedings.”

Don’t disturb the Jury!

S8 prevents any investigation into events which might have occurred within the jury’s retiring room.  In the absence of effective research into the reasoning process behind jury verdicts, it is difficult to gauge with any certainty the extent to which the average juror is capable of understanding and applying sometimes complex legal principles.

The principle that jurors can never be impugned for their verdict has existed for hundreds of years. In Bushell’s Case 1670 a jury had been fined for returning a verdict deemed to be contrary to the evidence. Bushell refused to ...
