Voting for the Foral Parliament was on the basis of universal suffrage, which comprised all nationals over 18 years of age, registered in Navarre and in full enjoyment of their civil and political rights.

The 70 members of the Foral Parliament of Navarre were elected using the D'Hondt method and a closed list proportional representation, with an electoral threshold of five percent of valid votes—which includes blank ballots—being applied in each constituency.

[1][2][3] The use of the D'Hondt method might result in a higher effective threshold, depending on the district magnitude.

[4] The electoral law allowed for parties and federations registered in the interior ministry, coalitions and groupings of electors to present lists of candidates.

Parties and federations intending to form a coalition ahead of an election were required to inform the relevant Electoral Commission within fifteen days of the election call, whereas groupings of electors needed to secure the signature of at least one-thousandth of the electorate in the constituencies for which they sought election—with a compulsory minimum of 500 signatures—disallowing electors from signing for more than one list of candidates.
