Parliaments as changing institutions and as agents of regime change: Evolving perspectives and a new research framework

In this review, the scholarly literature dealing with the role and dynamics of parliaments as institutions that undergo change within themselves and that support and enhance change in the larger regime is considered. One central theory of scholarship dealing with parliamentary change, that of legislative institutionalisation, is examined and found wanting as an explanation of change in mature parliamentary institutions. In discussion of analyses of five instances of parliamentary change, it is shown that parliaments can change in a wide variety of contexts and conditions ‐ including such well‐established legislatures as the United States Congress after over 200 years of evolution. There is no ‘end of history’ in parliamentary change, only the possibility of sometimes startling change from what has gone before. The examination of five instances of parliamentary change also supports the thesis that parliamentary institutional change, and regime change enhanced by parliamentary change, are inexorably linked. Finally, a tentative research framework is evolved from the above analyses and proposed as a means for considering the role of parliaments as changing institutions and as institutions enhancing systemic change.
