Organisation theory and work on legislative institutionalisation1 suggest that institutionalisation occurs at two levels. The first and most basic is in terms of specialisation within the legislature: that is, delegating tasks to particular bodies, usually committees. Legislatures may be arrayed on a spectrum, with chamber-oriented legislatures which make little or no use of committees at one end and legislatures which are committee-oriented, to the extent of giving committees power to enact legislation, at the other.2
