The President has the right to initiate the legislative process. They also have the opportunity to directly influence it by using their veto to stop a bill; however, a veto can be overruled by a three-fifths majority vote in the presence of at least half of the statutory number of members of the Sejm (230). Before signing a bill into law, the President can also ask the Constitutional Tribunal to verify its compliance with the Constitution, which in practice bears a decisive influence on the legislative process.
