The legal system of Chile belongs to the Continental Law tradition. The basis for its public law is the 1980 Constitution, reformed in 1989 and 2005. According to it Chile is a democratic republic. There is a clear separation of functions, between the President of the Republic, the Congress, the judiciary and a Constitutional Court. See Politics of Chile. On the other hand, private relationships are governed, mainly, by the Chilean Civil Code, most of which has not been amended in 150 years. There are also several laws outside the Code that deal with most of the business law.
