Party greater than people?!

Kerala Chief Minister has been removed from the CPM Polit Bureau for "violating the organisational principles and discipline." However, he can still remain the CM. This beats me totally! How can someone who is charged for violation of principles and discipline be allowed to continue as the Chief Minister of a state? Is the party more important to the CPM than the people? Does the post mean nothing to the party, that supposedly prides itself in morality?!
