Supra majority and making Sri Lanka great- or break

What stands against the absolutism is the constitutionally mandated safeguards against excesses of political leadership. However, in the developing world, most of which are in different phases of transition to liberal democracies, such constitutional safeguards are fragile. That is because the evolution of the institutions of the state has not kept up to the pace of the social and political mobilisation of the population in those countries. Also, the social and economic representation of the population themselves, who are overwhelmingly poor or the lower middle class is staked against the optimum function of democracy. For a democracy to succeed and consolidate, a Middle Class is a prerequisite, a Middle Class defined not just in money, but as a combination of education, economic and social and cultural factors. Effectively, even in the best of the times, independent institutions are at the mercy of all-powerful, and populist political leadership. A supra majority makes it worse.   

In Sri Lanka, the 2/3 majority has historically been used to advanced personalised political projects. J.R. Jayewardene, whose government emerged with 5/6th in the House, resorted to a referendum instead of a general election to extend its term, and within its term, it passed 16 amendments out of the total of 19 amendments to the constitution.
