  A unicameral parliament (Sabor) holds legislative power. The number of Sabor members can vary from 100 to 160. They are elected by popular vote to serve four-year terms. Legislative sessions take place from 15 January to 15 July, and from 15 September to 15 December annually. The two largest political parties in Croatia are the Croatian Democratic Union and the Social Democratic Party of Croatia.
  
  Croatia has a civil law legal system in which law arises primarily from written statutes, with judges serving as implementers and not creators of law. Its development was largely influenced by German and Austrian legal systems. Croatian law is divided into two principal areas— private and public law. Before EU accession negotiations were completed, Croatian legislation had been fully harmonised with the Community acquis.
  
  The main national courts are the Constitutional Court, which oversees violations of the Constitution, and the Supreme Court, which is the highest court of appeal. Administrative, Commercial, County, Misdemeanor, and Municipal courts handle cases in their respective domains. Cases falling within judicial jurisdiction are in the first instance decided by a single professional judge, while appeals are deliberated in mixed tribunals of professional judges. Lay magistrates also participate in trials. The State's Attorney Office is the judicial body constituted of public prosecutors empowered to instigate prosecution of perpetrators of offences.
  
  Law enforcement agencies are organised under the authority of the Ministry of the Interior which consist primarily of the national police force. Croatia's security service is the Security and Intelligence Agency (SOA).
