Electoral system

The Parliament of La Rioja was the devolved, unicameral legislature of the autonomous community of La Rioja, having legislative power in regional matters as defined by the Spanish Constitution and the Riojan Statute of Autonomy, as well as the ability to vote confidence in or withdraw it from a regional president.^[1] Voting for the Parliament was on the basis of universal suffrage, which comprised all nationals over 18 years of age, registered in La Rioja and in full enjoyment of their political rights. Additionally, Riojans abroad were required to apply for voting before being permitted to vote, a system known as "begged" or expat vote (Spanish: Voto rogado).^[2]

The 33 members of the Parliament of La Rioja were elected using the D'Hondt method and a closed list proportional representation, with an electoral threshold of five percent of valid votes—which included blank ballots—being applied regionally.^[1][3]

Election date

The term of the Parliament of La Rioja expired four years after the date of its previous election. Elections to the Parliament were fixed for the fourth Sunday of May every four years. The previous election was held on 24 May 2015, setting the election date for the Parliament on Sunday, 26 May 2019.^[1][3][4]

The president had the prerogative to dissolve the Parliament of La Rioja and call a snap election, provided that no motion of no confidence was in process, no nationwide election was due and some time requirements were met: namely, that dissolution did not occur either during the first legislative session or within the legislature's last year ahead of its scheduled expiry, nor before one year had elapsed since a previous dissolution. In the event of an investiture process failing to elect a regional president within a two-month period from the first ballot, the Parliament was to be automatically dissolved and a fresh election called. Any snap election held as a result of these circumstances would not alter the period to the next ordinary election, with elected deputies merely serving out what remained of their four-year terms.^[1]

The election to the Parliament of La Rioja was officially triggered on 2 April 2019 after the publication of the election decree in the Official Gazette of La Rioja (BOR), scheduling for the chamber to convene on 20 June.^[5]
