Role in appeals Jury instructions play a significant role in the appellate process; errors or omissions in the instructions can provide grounds for an appeal. Appellate courts may review instructions given to the jury to determine if they were made in a legally permissible manner. If the appellate court finds an error in the instructions process, it may, if sufficiently problematic, reverse a decision or order a new trial.
Comprehending jury instructions A significant issue with standard jury instructions is the language comprehension difficulties for the average juror. The purpose of jury instructions is to inform jurors of relevant laws and their application in the process of coming to a verdict. However, studies have shown that juries consistently run into problems understanding the instructions given to them. Poor comprehension is noted across juror demographics, as well as across legal contexts. Various linguistic features of legalese or
legal English, such as complex sentence structures and technical
jargon, have been pinpointed as major factors contributing to low comprehension. The new instructions read: Resistance to the movement towards the revision of standard jury instructions exists as well. This is due to the concern that moving away from legal English will result in jury instructions becoming imprecise. There is also the belief that jurors prefer judges to speak in legal language so that they come across as educated and respectable.
Jury nullification instructions There is also debate, particularly active in the US, over whether juries that are to judge a criminal case should be informed of the possibility of
jury nullification during jury instructions. One argument states that if juries have the power of jury nullification, then they should be informed of it and that neglecting to do so is an act of intervention. Another argument states that defendants should be judged according to the law, and that jury nullification interferes with this process. It is also debated that instructions permitting jury nullification is to be criticized as promoting chaos, as it brings the decision between having a structured set of rules and having less of said rules for a more free set of choices that could also promote the likes of
anarchy and
tyranny. Studies have indicated that being informed of jury nullification is likely to affect the judgement of juries when they decide on verdicts. One study that looked into 144 juries showed that they were less harsh on sympathetic defendants and harsher on unsympathetic defendants when they had been briefed on jury nullification. Another study that looked into 45 juries showed that they were likelier to reach a guilty verdict in drunk driving cases and less likely in euthanasia cases, with no reported difference in likelihood in murder cases, with the inclusion of explicit jury nullification details in jury instructions. == Specific jurisdictional issues ==
