and Regions, and between Regions; charges brought against the President of the Republic, according to the provisions of the Constitution. The Constitutional Court is composed of fifteen judges, a third nominated by the President, a third by Parliament in joint sitting and a third by the ordinary and administrative supreme Courts. The judges of the Constitutional Courts must be chosen from among judges, including those retired, of the ordinary and administrative higher Courts, university professors of law and lawyers with at least twenty years practice. Judges of the Constitutional Court are appointed for nine years, beginning in each case from the day of their swearing in, and they cannot be re-appointed. At the expiration of their term, the constitutional judges must leave office and the exercise of the functions thereof. The President of the Court is elected for three years and with the possibility of re-election from among its members, in accordance with the law and respecting in all cases the expiry term for constitutional judges. The office of constitutional judge is incompatible with membership of Parliament, of a Regional Council, the practice of the legal profession, and with every appointment and office indicated by law. In impeachment procedures against the President of the Republic, in addition to the ordinary judges of the Court, there must also be sixteen members chosen by lot from among a list of citizens having the qualification necessary for election to the Senate, which the Parliament prepares every nine years through election using the same procedures as those followed in appointing ordinary judges. When a law is declared unconstitutional by the Court, the law ceases to have effect the day following the publication of the decision. The decision of the Court must be published and communicated to Parliament and the Regional Councils concerned, so that, wherever they deem it necessary, they shall act in conformity with constitutional procedures. A constitutional law establishes the conditions, forms, terms for proposing judgements on constitutional legitimacy, and guarantees on the independence of constitutional judges. Ordinary laws establishes the other provisions necessary for the constitution and the functioning of the Court. No appeals are allowed against the decision of the Constitutional Court.
