Definition: Vice-judex (vIs-joo-deks) is a historical term that refers to a deputy judge.

Example: In medieval England, the king would appoint a vice-judex to assist the main judge in hearing cases and making decisions.

Explanation: A vice-judex was a legal official who acted as a substitute for a judge when they were unable to perform their duties. This could be due to illness, absence, or other reasons. The vice-judex would have the same authority as the main judge and would be responsible for hearing cases and making decisions. The example illustrates how the term was used in medieval England to describe a specific legal role.
