The need for a comprehensive reform of Finland's four laws of constitution has been discussed since the late 1960s. As a consequence of several substantial changes to the old constitutional laws and the political consensus to move the system of governance in a more parliamentary direction, a new Constitution was drafted during the 1990s and adopted by the Parliament in 1999. Finland's new Constitution integrates constitutional provisions into a single Constitution, and reduces the constitutional powers of the president of the republic. The new Constitution increases parliamentary control in foreign policy. It requires the president to co-operate with the government when directing Finland's foreign policy. It also requires acceptance by the Parliament of a wider range of international obligations. The system for the national organisation of matters concerning the European Union adopted in connection with Finland's accession to the Union in 1995 has also been confirmed by the Constitution, with the government and the Parliament being the main actors in that field.
