elections were held on 29 February 2020 and two rounds of presidential elections took place on 16 and 30 March 2019. The Slovak head of state and the formal head of the executive is the president (currently Zuzana Čaputová, the first female president), though with very limited powers. The president is elected by direct, popular vote under the two-round system for a five-year term. Most executive power lies with the head of government, the prime minister (currently Eduard Heger), who is usually the leader of the winning party and who needs to form a majority coalition in the parliament. The prime minister is appointed by the president. The remainder of the cabinet is appointed by the president on the recommendation of the prime minister. Slovakia's highest legislative body is the 150-seat unicameral National Council of the Slovak Republic (Národná rada Slovenskej republiky). Delegates are elected for a four-year term on the basis of proportional representation. Slovakia's highest judicial body is the Constitutional Court of Slovakia (Ústavný súd), which rules on constitutional issues. The 13 members of this court are appointed by the president from a slate of candidates nominated by parliament. The Constitution of the Slovak Republic was ratified 1 September 1992, and became effective 1 January 1993. It was amended in September 1998 to allow direct election of the president and again in February 2001 due to EU admission requirements. The civil law system is based on Austro-Hungarian codes. The legal code was modified to comply with the obligations of Organization on Security and Cooperation in Europe (OSCE) and to expunge the Marxist–Leninist legal theory. Slovakia accepts the compulsory International Court of Justice jurisdiction with reservations. |President |Zuzana Čaputová |Independent |15 June 2019 |- |Prime Minister |Eduard Heger |OĽaNO |1 April 2021 |- |National Council Chairman |Boris Kollár |SR |21 March 2020 |} Foreign relations The Ministry of Foreign and European Affairs () is responsible for maintaining the Slovak Republic's external relations and the management of its international diplomatic missions.
