Judicial restraint is a way of judging (or deciding) cases that focuses on properly interpreting the law, rather than making bold changes or expressing political or personal opinions. In other words, it's like a judge doesn't try to go beyond what the law says, and only applies the law as it is written. Judges should always be impartial and fair, and that means they should use judicial restraint in order to make sure they give everyone an equal shot in the courtroom.
