What happens if some or all wings fail to do their job properly ? At present the only option is for the judiciary to apply corrective actions, which is one way of looking at the Lodha report and judgement.
In some other societies there is an additional option, that of popular overthrow of the regime and creation of a new State. In India it is not the habit of the People to overthrow anything, and sadly the Constitution does not seem to provide for a new Constituent Assembly or new Constitution. Nor would a new document do much better than the existing one, as the failures are not caused by the document but by those who have to implement it.
After all the allegations of corruption in cricket are very well known and most of the details of it are also well established, but neither Executive nor Legislature took any action. As both the Executive and the Legislature are bodies of politicians alone, the failure can be attributed to the politicians of the country being not interested in doing their allotted work under the Constitution.
Judiciary consists of professionals of Justice, that is of matters concerning Right and Wrong, while politicians deal with matters of Power rather than Morality.
If judiciary too did not interfere then the entire State of India would have failed to deal with the problem, which is not a minor or self solving type.
