[2] Voting for the Parliament was on the basis of universal suffrage, which comprised all nationals over 18 years of age, registered in the Balearic Islands and in full enjoyment of their political rights.

The 59 members of the Parliament of the Balearic Islands 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 in each constituency.

[2][3] After legal amendments in 2007, fixed-term mandates were abolished, instead allowing the term of the Parliament of the Balearic Islands to expire after an early dissolution.

[2][3][4] The president had the prerogative to dissolve the Parliament of the Balearic Islands and call a snap election, provided that no motion of no confidence was in process and that dissolution did not occur before one year had elapsed since the previous one.
