It is the confusing number of committees that gave rise to the term "comitology". A report from the British House of Lords said, "There is no definitive list of comitology committees, their functions, activities and membership"; however, since the European Commission started to maintain a list, it states that "A list of 'comitology' committees [...] is published as an Annex to the Annual reports on the work of these Committees [...] as well as in the Register of Comitology." Moreover, the strongest criticism pertained to the fact that the elected European Parliament (EP) had no right to block implementing measures: only the comitology committees could do so, and if they did, the proposal was referred to Council alone, even when the initial delegation of powers was through an act adopted jointly by both Parliament and Council under the co-decision procedure. Parliament argued that the system lacked transparency and democratic control.
