At the local level, the island's 22 provinces are administered by a governor and provincial council. Provinces are further subdivided into regions and communes. The judiciary is modeled on the French system, with a High Constitutional Court, High Court of Justice, Supreme Court, Court of Appeals, criminal tribunals, and tribunals of first instance. The courts, which adhere to civil law, lack the capacity to quickly and transparently try the cases in the judicial system, often forcing defendants to pass lengthy pretrial detentions in unsanitary and overcrowded prisons.
