La disciplina dei gruppi parlamentari, nel mutare delle leggi elettorali

The contribution examines the evolution of the regulation of parliamentary groups in the Italian Chamber and Senate. The analysis moves from the very first provisions regulating this matter, which were introduced in 1920 under the Albertine Statute. Then, the contribution explores the reactivation of the regulation of parliamentary groups at the dawn of the Italian Republican experience, investigating its subsequent transformations, until today, in connection with the evolution of a very unstable electoral legislation.
