Finland
The judicial system of Finland is a civil law system divided between courts with regular civil and criminal jurisdiction and administrative courts with jurisdiction over litigation between individuals and the public administration. Finnish law is codified and based on Swedish law and in a wider sense, civil law or Roman law. The court system for civil and criminal jurisdiction consists of local courts ("käräjäoikeus", "tingsrätt"), regional appellate courts ("hovioikeus", "hovrätt"), and the Supreme Court ("korkein oikeus", "högsta domstolen"). The administrative branch of justice consists of administrative courts ("hallinto-oikeus", "förvaltningsdomstol") and the Supreme Administrative Court ("korkein hallinto-oikeus", "högsta förvaltningsdomstolen"). In addition to the regular courts, there are a few special courts in certain branches of administration. There is also a High Court of Impeachment for criminal charges against certain high-ranking officeholders.
