Ibiza (Parliament of the Balearic Islands constituency)
Ibiza () is one of the four constituencies () represented in the Parliament of the Balearic Islands, the regional legislature of the Autonomous Community of the Balearic Islands. The constituency currently elects 12 deputies. Its boundaries correspond to those of the island of Ibiza. The electoral system uses the D'Hondt method and a closed-list proportional representation, with a minimum threshold of five percent. Until the 2003 election, the results in this district were also used to determine the composition of the Island Council of Ibiza and Formentera during the same term as the Parliament , with Ibiza counting for 12 out of the 13 seats of the Council—11 out of 12 from 1983 to 1987—. From the 2007 election onwards, a separate election is held, also having both Ibiza and Formentera independent Councils, the Island Council of Ibiza electing 13 members. Additionally, on 3 April 1979 the first independent election for the Island Council of Ibiza and Formentera was held, electing 12 councillors. Electoral system. The constituency was created as per the Statute of Autonomy of the Balearic Islands of 1983 and was first contested in the 1983 regional election. The Statute provided for the  four main islands in the Balearic archipelago—Majorca, Menorca, Ibiza and Formentera—to be established as multi-member districts in the Parliament of the Balearic Islands, with this regulation being maintained under the 1986 regional electoral law. Each constituency is allocated a fixed number of seats: 33 for Majorca, 13 for Menorca, 12 for Ibiza and 1 for Formentera. The exception was the 1983 election, when these numbers were 30, 12, 11 and 1, respectively. Voting is on the basis of universal suffrage, which comprises all nationals over eighteen, registered in the Balearic Islands and in full enjoyment of their  political rights. Amendments to the electoral law in 2011 required for Balearic citizens abroad to apply for voting before being permitted to vote, a system known as "begged" or expat vote (). Seats are 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; until a 1995 reform, the threshold was set at three percent—being applied in each constituency. The use of the D'Hondt method may result in a higher effective threshold, depending on the district magnitude. The electoral law allows 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 are required to inform the relevant Electoral Commission within ten days of the election call—fifteen before 1985—whereas groupings of electors need to secure the signature of at least one percent of the electorate in the constituencies for which they seek election—one-thousandth of the electorate, with a compulsory minimum of 500 signatures, until 1985—disallowing electors from signing for more than one list of candidates.
