The Assembly of Extremadura was the devolved, unicameral legislature of the autonomous community of Extremadura, having legislative power in regional matters as defined by the Spanish Constitution and the Extremaduran Statute of Autonomy, as well as the ability to vote confidence in or withdraw it from a President of the Regional Government. Voting for the Assembly was on the basis of universal suffrage, which comprised all nationals over eighteen, registered in Extremadura and in full enjoyment of their political rights. The 65 members of the Assembly of Extremadura were elected using the D'Hondt method and a closed list proportional representation, with a threshold of 5 percent of valid votes—which included blank ballots—being applied in each constituency. Parties not reaching the threshold were not taken into consideration for seat distribution. Alternatively, parties failing to reach the threshold in one of the constituencies would also be entitled to enter the seat distribution as long as they ran candidates in both districts and reached 5 percent regionally. Seats were allocated to constituencies, corresponding to the provinces of Badajoz and Cáceres. Each constituency was allocated a fixed number of seats: 35 for Badajoz and 30 for Cáceres. The electoral law provided that parties, federations, coalitions and groupings of electors were allowed to present lists of candidates. However, groupings of electors were required to secure the signature of at least 0.1 percent of the electors registered in the constituency for which they sought election—needing to secure, in any case, the signature of 500 electors—. Electors were barred from signing for more than one list of candidates. Concurrently, parties and federations intending to enter in coalition to take part jointly at an election were required to inform the relevant Electoral Commission within fifteen days of the election being called.
Election date
The Junta of Extremadura, in agreement with the Government of Spain, was required to call an election to the Assembly of Extremadura before 31 May 1983. In the event of an investiture process failing to elect a regional President within a two-month period from the first ballot, the Assembly was to be automatically dissolved and a snap election called, with elected deputies merely serving out what remained of their four-year terms.
