The Legislative Assembly of Umbria (Assemblea Legislativa dell'Umbria) is composed of 21 members. 19 councillors are elected in provincial constituencies by proportional representation using the largest remainder method with a Droop quota and open lists, while the remaining two are the elected President and the candidate for president who comes second. The winning coalition wins a bonus of seats in order to make sure the elected president has a majority in the assembly.
The assembly is elected for a five-year term, but, if the President suffers a vote of no confidence, resigns or dies, under the simul stabunt, simul cadent (literally they will stand together or they will fall together) clause introduced in the Italian Constitution in 1999 and later incorporate in the Statute of Umbria, also the assembly is dissolved and an early election is called.
