The Czech system has a weak president and strong parliament. The president can veto bills passed by both houses of parliament but the parliament can override the veto with an absolute majority, so much easier to do than in the U.S. The president also has sole authority to appoint members of the judiciary and the national bank and can dissolve parliament under certain circumstances which I have yet to fully understand. Mostly, the role of the president of the Czech Republic is as the face of the country, the head of state who engages in diplomacy and state visits, but does not set foreign policy, only advises.
