How Juries Work in Criminal Trials
Once selected, jurors swear an oath to "faithfully try the defendant according to the evidence" - this is where things get properly serious. Each jury is empanelled for just one case, so you're totally focused on that single trial.
The jury's job is straightforward but crucial: listen to evidence and barristers' arguments, hear the judge's summary, decide the facts, then apply the law as the judge explains it. After retiring to the jury room for secret discussions, they must return a verdict of guilty or not guilty.
Unanimous verdicts (all 12 agreeing) are preferred, but majority verdicts are acceptable if at least 10 jurors agree. The spokesperson then announces the verdict in open court - imagine that pressure!
Both prosecution and defence can challenge jurors through "challenge for cause" (removing individual jurors for specific reasons) or "challenge to array" (very rarely, challenging the whole jury as unrepresentative).
Key Point: What happens in the jury room stays in the jury room - their discussions are completely secret and can never be investigated, even if the verdict seems wrong to others.
