Final answer:
In a trial, judges and jurors must presume the innocence of the accused unless a presumption is overcome with other evidence.
Step-by-step explanation:
In a trial, unless a presumption is overcome with other evidence, judges and jurors must presume the innocence of the accused. This means that the defendant is considered innocent until proven guilty beyond a reasonable doubt. It is the responsibility of the prosecution to present evidence that convinces the judge or jury that the defendant is guilty.
