The 1987 Castile and León parliamentary election was held on Wednesday, 10 June 1987, to elect the 2nd Courts of Castile and León, the regional legislature of the Spanish autonomous community of Castile and León. At stake were all 84 seats in the Courts, determining the President of the Junta of Castile and León.
Electoral system
The number of seats in the regional Courts was determined by the population count. For the 1987 election, the Courts size was set to 84 seats. All Courts members were elected in 9 multi-member districts, corresponding to Castile and León's nine provinces, using the D'Hondt method and a closed-list proportional representation system. Each district was entitled to an initial minimum of 3 seats, with 1 additional seat per each 45,000 inhabitants or fraction greater than 22,500. For the 1987 election, seats were distributed as follows: Avila (7), Burgos (11), Leon (15), Palencia (7), Salamanca (11), Segovia (6), Soria (5), Valladolid (14) and Zamora (8).
Voting was on the basis of universal suffrage in a secret ballot. Only lists polling above 3% of valid votes in each district (which include blank ballots—for none of the above) were entitled to enter the seat distribution.
