In a constitutional democracy, the constitution is the supreme law and governance cannot be on the basis of personal prejudices or the whims and fancies of individuals. The purpose of the constitution is to take political decision making out of that personal realm to give stability and predictability to government. It is now a month since the Black Friday of October 26 when the Sri Lankan polity was plunged into a constitutional and political crisis by President Maithripala Sirisena when he decided he had no option but to sack Prime Minister Ranil Wickremesinghe and his government, and just as arbitrarily to replace him with former president Mahinda Rajapaksa from the ranks of the opposition.
