The 2003 Catalan regional election was held on Sunday, 16 November 2003, to elect the 7th Parliament of the autonomous community of Catalonia. All 135 seats in the Parliament were up for election. This election marked a change for all Catalan political parties due to Catalan president Jordi Pujol's decision not to seek a seventh term in office and to retire from active politics. The election results were a great disappointment for Pasqual Maragall's Socialists' Party of Catalonia (PSC), which again saw Convergence and Union (CiU) winning a plurality of seats despite them winning the most votes by a margin of just 0.3%. Opinion polls earlier in the year had predicted a much larger victory for Maragall, but his lead over CiU had begun to narrow as the election grew nearer. Republican Left of Catalonia (ERC) was perceived as the true victor of the election, doubling its 1999 figures and scoring its best result in its recent history up to that point, both in terms of seats (23 of 135) and votes (16.4%), up from 11 seats and 8.7%. As Pujol's successor Artur Mas did not win a majority large enough to renew his party pact with the People's Party (PP), which had kept Pujol in power since 1995, an alliance between the PSC, ERC and ICV–EUiA resulted in a Catalan "tripartite" government. Thus, despite losing 10 seats and 150,000 votes compared to the 1999 election, Maragall became the first centre-left president of the Government of Catalonia, ending with 23 uninterrupted years of CiU rule. Overview Electoral system The Parliament of Catalonia was the devolved, unicameral legislature of the autonomous community of Catalonia, having legislative power in regional matters as defined by the Spanish Constitution of 1978 and the regional Statute of Autonomy, as well as the ability to vote confidence in or withdraw it from a regional president. Transitory Provision Fourth of the Statute established a specific electoral procedure for elections to the Parliament of Catalonia, of application for as long as a specific law regulating the procedures for regional elections was not approved, to be supplemented by the provisions within the Organic Law of General Electoral Regime. Voting for the Parliament was on the basis of universal suffrage, which comprised all nationals over 18 years of age, registered in Catalonia and in full enjoyment of their political rights.
