Voting was on the basis of universal suffrage in a secret ballot. The electoral system used was closed listproportional representation in five electoral districts with seats allocated using the D'Hondt method. Only lists which polled at least 5% of the total votes cast in the Region (including votes "en blanco" i.e. for "none of the above") were eligible for seats, which were then allocated in each electoral district according to the vote share in that district. This rule prevented Union, Progress and Democracy from winning a seat as, although they polled 5.3% in the third district, their vote in the entire Murcian region was 4.5%.
The Spanish Socialist Workers' Party (PSOE) won the first three elections in the Murcia Region, however all four elections from 1995 onwards had been won by the People's Party (PP) who had won an absolute majority of votes and seats since then. The PP gained four seats from the PSOE, with United Left holding its solitary seat.
The five electoral districts are numbered one to five, but are also known by geographic descriptors. Following a review of the electoral law, the third district, Murcia, gained a seat at the expense of the second district.
