He has also certain incidental duties.
Court Commissioner .-- Court is not always in session, and there are certain powers possessed by a judge "in chambers," that is, which the judge may exercise out of court.

For instance, he may grant a writ of attachment or of _habeas corpus_.

Where a judicial district comprises several counties, as is usually the case, a provision is made in some states for an officer in each county authorized to perform such duties in the absence of the judge.

In Minnesota and most other states he is called the court commissioner.
Election and Term .-- The county officers are in most sections of the country elected by the people of the county.

The term is usually two years.
Removals and Vacancies .-- Provision is made for the removal of any county officer for non-feasance or malfeasance in office.
