The Lithuanian legal system is based on civil law principles, primarily influenced by the German and French legal traditions. It operates under the Constitution of Lithuania, which was adopted in 1992, and serves as the highest legal authority in the country. The system includes various branches of law, such as criminal, civil, and administrative law, and is characterized by a codified structure. The judiciary in Lithuania is independent, comprising the Supreme Court, Court of Appeal, and regional courts. Legal professionals, including judges and lawyers, must meet specific qualifications and adhere to ethical standards. The system also emphasizes the protection of human rights and the rule of law.
