From the message body, it is understood that BJP is not against taking stern action against the erring MPs but the way action is taken. It is well accepted by every right thinking person that while taking action against someone who has disobeyed the rule of law, the action itself should not disobey the law. Otherwise it will be a bad precedent that if someone commits a mistake, it is alright to commit a mistake on him too. Is such a situation healthy for a democracy?
Summarizing, take stringent action against the erring MPs, but follow the rules and procedures.
