A more thorough explanation:

ECHEVIN

An echevin is a municipal officer in French law who has similar duties to an alderman or burgess. They may also have the power to hear and decide on minor cases.

An echevin in France may be responsible for overseeing local government functions, such as managing public works projects or organizing community events.

If a citizen has a dispute with their neighbor over a property line, they may bring their case to an echevin for a decision.

The examples illustrate how an echevin is a local government official who has a range of responsibilities, including civil jurisdiction over certain minor cases. They are similar to aldermen or burgesses in other countries, and their duties may include managing public works projects or resolving disputes between citizens.
