Members of the opposition denounced the bill and asked the King to veto it, and he did so in December 2011. Veto theories In political science, the broader power of people and groups to prevent change is sometimes analyzed through the frameworks of veto points and veto players. Veto players are actors who can potentially exercise some sort of veto over a change in government policy. Veto points are the institutional opportunities that give these actors the ability to veto. The theory of veto points was first developed by Ellen M. Immergut in 1990, in a comparative case study of healthcare reform in different political systems. Breaking with earlier scholarship, Immergut argued that "we have veto points within political systems and not veto groups within societies." Veto player analysis draws on game theory.
