Croatia has a civil law legal system in which law arises primarily from written statutes, with judges serving merely 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. By the time EU accession negotiations were completed on 30 June 2010, Croatian legislation was fully harmonised with the Community acquis. The main law in the country is the Constitution adopted on 22 December 1990.
