using the D'Hondt method and a closed list proportional representation, with an electoral threshold of three percent of valid votes—which included blank ballots—being applied in each constituency. Seats were allocated to constituencies, corresponding to the provinces of Barcelona, Girona, Lleida and Tarragona, with each being allocated a fixed number of seats. The use of the D'Hondt method might result in a higher effective threshold, depending on the district magnitude. Election date The term of the Parliament of Catalonia expired four years after the date of its previous election, unless it was dissolved earlier. The regional president was required to call an election fifteen days prior to the date of expiry of parliament, with election day taking place within sixty days after the call. The previous election was held on 17 October 1999, which meant that the legislature's term would have expired on 17 October 2003. The election was required to be called no later than 2 October 2003, with it taking place on the sixtieth day from the call, setting the latest possible election date for the Parliament on Monday, 1 December 2003. The president had the prerogative to dissolve the Parliament of Catalonia and call a snap election, provided that no motion of no confidence was in process and that dissolution did not occur before one year had elapsed since a previous one under this procedure. In the event of an investiture process failing to elect a regional President within a two-month period from the first ballot, the Parliament was to be automatically dissolved and a fresh election called. Background In the 1999 election, and as a result of the Socialists' Party of Catalonia (PSC)'s growth, the Catalan nationalist Convergence and Union (CiU) had lost the vote share in a regional election for the first time ever, but clung on to retain the largest amount of seats due to the disproportionate allocation of seats in Girona, Lleida and Tarragona compared to Barcelona. Through to the support of the People's Party (PP), Jordi Pujol had been able to be re-elected to a sixth term in office with a slim majority of 68 to the 67 seats commanded by the left-from-centre opposition. Despite Pujol's personal approval ratings remaining high until the end of his term, speculation on his possible retirement (which he confirmed on 1 April 2001), internal disputes between Democratic Convergence of Catalonia (CDC) and Democratic Union of Catalonia (UDC)
