The electoral system uses the D'Hondt method and a closed-list proportional representation, with a minimum threshold of five percent.

The Statute provided for the four provinces in Galicia—A Coruña, Lugo, Ourense and Pontevedra—to be established as multi-member districts in the Parliament of Galicia, with this regulation being maintained under the 1985 regional electoral law.

Each constituency is entitled to an initial minimum of 10 seats, with the remaining 35 being distributed in proportion to their populations.

In the 1981 and 1985 elections, each constituency was allocated a fixed number of seats: 22 for A Coruña, 15 for Lugo, 15 for Ourense and 19 for Pontevedra.

[2][3] Voting is on the basis of universal suffrage, which comprises all nationals over eighteen, registered in Galicia and in full enjoyment of their political rights.
