Junta Electoral Central

The Junta Electoral Central (JEC) (Central Electoral Commission) is the electoral commission for elections in Spain, monitoring and registering provincial elections, district elections, those of self-governing districts and general elections. It supervises the vote at polling stations. Its mission is to "ensure the transparency of the electoral process and monitor the performance of the Electoral Census Office."

It is based in Madrid, and was created by Spanish law on 26 June 1890 as Central Commission of the Electoral Census (Junta Central del Censo Electoral). During the transition to democracy, the Royal Decree-Law 20/1977 of 18 March, on Electoral Regulations, renamed it as Junta Electoral Central.

Composition
It comprises eight judges from the Supreme Court, five active professors of law and sociology, a secretary, and the director of the Electoral Census Office (part of the National Statistics Institute), who has a casting vote but is otherwise a sleeping partner.

Presidents
Before 1985, the Commission was chaired by the President of the Congress of Deputies (1890-1907) and by the President of the Supreme Court (1907-1985).
