Article 64 states that government can dissolve each House by Royal Decree. Within three months elections have to be held (Subarticle 2). The duration of a new House of Representatives after dissolution is determined by law and not to exceed five years (Subarticle 4). The dissolution only takes effect when the new House meets, to avoid a period without representation. Dissolution of Parliament was in the 19th century an instrument for government to decide a conflict with the House of Representatives by submitting the issue to the voter. Unwritten law developed between 1866 and 1868 that this should not be done more than once over the same issue. The last instance occurred in 1894. In the 20th century such "conflict resolution" was replaced by "crisis resolution" whenever a political coalition fell apart and could not be reconciled; the government then resigns and instead of trying to find a new coalition majority, decides on holding new elections, normally in accordance with the wishes of parliament itself. Earlier typically an "interim cabinet" was formed to arrange for the elections, but this hasn't happened since 1982.
