It was a series of circumstances. There have been small adjustments, but the last major reform of the calendar was in 1984. However, Parliament had changed quite a bit in the meantime. Parliamentarians had asked that a number of aspects in the standing orders be amended. Two government leaders at the time introduced reform proposals. The speaker of the Assembly himself introduced a plan to reform a host of issues.
A committee was formed in 2008, I think, to study those proposals. The reform took place in 2009. The calendar was one of the key issues discussed. That is still the case today. A technical committee made up of parliamentary leaders meets to discuss future reforms or adjustments to the standing orders. The parliamentary calendar is clearly still one of the items on the agenda.
