A more thorough explanation:

A visiting judge is a temporary judge appointed by the presiding judge of an administrative region to sit on a given court, usually in the regular judge's absence. They are also known as temporary judges or judge pro tempore.

• When the regular judge is on vacation, a visiting judge may be appointed to hear cases in their absence.
• A visiting judge may be called upon to hear a case in a different jurisdiction where they are not a regular judge.

These examples illustrate how a visiting judge is a temporary replacement for a regular judge, appointed to ensure that cases can still be heard and decided in the regular judge's absence.
