The legal system of Kazakhstan is based on the Romano-Germanic legal system. The current law in the Republic of Kazakhstan is the norms of the Constitution, laws corresponding to it, other regulatory legal acts, international treaties and other obligations of the Republic, as well as regulatory resolutions of the Constitutional Court and the Supreme Court of the Republic. The primary law source in Kazakhstan is the following regulatory legal acts: legislative acts and by-laws.

The Constitution of the Republic of Kazakhstan, adopted by a national referendum on August 30, 1995, is the country’s fundamental law. It is designed to strengthen the foundations of the constitutional order, the rights and freedoms of man and citizen, and the state structure foundations. The Constitution of the Republic of Kazakhstan has the highest legal force concerning all other legal acts: none of the legal acts adopted in the country (constitutional law, Presidential Decree, Government decree, regional law-making act, decree, etc.) can contradict the Basic Law, and in case of conflict (legal conflicts), the Constitution takes precedence. The Constitution of the Republic of Kazakhstan is the core of the state’s legal system and the basis of the current (industry) legislation.
