Judge

A judge presides over court proceedings, either alone or as a part of a panel of judges. The powers, functions, method of appointment, discipline, and training of judges vary widely across different jurisdictions. The judge is supposed to conduct the trial impartially and in an open court. The judge hears all the witnesses and any other evidence presented by the barristers of the case, assesses the credibility and arguments of the parties, and then issues a ruling on the matter at hand based on his or her interpretation of the law and his or her own personal judgment. In some jurisdictions, the judge's powers may be shared with a jury. In inquisitorial systems of criminal investigation, a judge might also be an examining magistrate.

Symbols of office

A variety of traditions have become associated with the rank or occupation.

In many parts of the world, judges wear long robes (often in black or red) and sit on an elevated platform during trials (known as the bench).

In some countries, especially in the Commonwealth of Nations, judges wear wigs. The long wig often associated with judges is now reserved for ceremonial occasions, although it was part of the standard attire in previous centuries. A short wig resembling but not identical to a barrister's wig would be worn in court. This tradition, however, is being phased out in Britain in non-criminal courts.
