In each département, the prefect draws up a list of persons authorised to perform the duties of jury members. Their number is defined according to the total population of the department concerned, as follows:
– department with a population of less than 500,000: at least 15 people;
– department with a population of 500,000 or more and less than one million: at least 20 people;
– department with a population of one million or more: at least 30 people.
These lists are updated every three years, without prejudice to the replacement of people who have died or moved outside the department. They enable training organisations to respect gender parity when constituting juries.
