Well, the court doesn't decide if something is illegal or not, that's already set out by the law. The court decides if the accused is guilty of the illegal act.

In this case the High Court won’t decide whether an “accused” is “guilty” or “not guilty”. The High Court will decide what “already set out by the law”
means.
