Composition The Constitutional Court is composed of 15 judges for the term of service of nine years: 5 appointed by the President, 5 elected by the Parliament of Italy[3] and 5 elected by the ordinary and administrative supreme courts. Candidates need to be either lawyers with twenty years or more experience, full professors of law, or (former) judges of the Supreme Administrative, Civil and Criminal tribunals.[4] The members then elect the President of the Court, since 11 December 2019 this has been Marta Cartabia. The President is elected from among its members in a secret ballot, by an absolute majority (8 votes in the case of a full court). If no person gets a majority, a runoff election between the two judges with the most votes occurs. The President of the Court appoints one or more vice-presidents to stand in for him in the event of his absence for any reason.
