Judges play many roles. They interpret the law, assess the evidence presented, and control how hearings and trials unfold in their courtrooms. Most important of all, judges are impartial decision-makers in the pursuit of justice. We have what is known as an adversarial system of justice - legal cases are contests between opposing sides, which ensures that evidence and legal arguments will be fully and forcefully presented. The judge, however, remains above the fray, providing an independent and impartial assessment of the facts and how the law applies to those facts.
