During the trial, they listen to what each attorney says and decide what evidence can be used. They also decide which questions an attorney can ask. Judges often settle small disagreements between lawyers. Some trials use juries to decide cases. Judges explain the laws to the juries before they make their decision.
Judges also give the jury information about evaluating the information given.
If juries find people guilty, then judges decide the sentence. Judges also decide if the defendant needs to be paid for court or other costs. Judges also work outside the courtroom. They read papers or laws about cases. When a case is decided, judges write their opinions.
