The Regional Council of Abruzzo was originally composed of 40 regional councillors. The number of regional councillors increased to 43 in the
2000 regional election and, subsequently, to 45 in the
2008 regional election. The Council is elected for a five-year term, but, if the President suffers a vote of no confidence, resigns or dies, under the
simul stabunt vel simul cadent clause (introduced in 1999), also the Council will be dissolved and there will be a snap election. Following the decree-law n. 138 of 13 August 2011 the number of regional councillors was reduced to 30, with an additional seat reserved for the President of the Region.
