The head of state is the President of Moldova, who between 2001 and 2015 was elected by the Moldovan Parliament, requiring the support of three-fifths of the deputies (at least 61 votes). The president of Moldova has been elected by the parliament since 2001, a change designed to decrease executive authority in favour of the legislature. Nevertheless, the Constitutional Court ruled on 4 March 2016, that this constitutional change adopted in 2000 regarding the presidential election was unconstitutional, thus reverting the election method of the President to a two-round system direct election.
