Read the following passage carefully and answer the questions that follow. Good governance is only in the hands of good men. No doubt, what is good or bad is not for the court to decide: but the court can always indicate the constitutional ethos on goodness, good governance and purity in administration remind the constitutional functionaries to preserve, protect and promote the same. That ethos are the unwritten words in our Constitution. However, as the Constitution makers stated, there is a presumption that the Prime Minister/Chief Minister would be well advised and guided by such unwritten yet constitutional principles as well.

According to Dr. B. R. Ambedkar, such things were only to be left to the good sense of the Prime Minister, and for that matter, the Chief Minister of State, since it was expected that the two great constitutional functionaries would not dare to do any infamous thing by inducting an otherwise unfit person to the Council of Ministers. It appears, over a period of time, at least in some cases, it was only a story of great expectations. Some of the instances pointed out in the writ petition indicate that Dr. Ambedkar and other great visionaries in the Constituent Assembly have been bailed out. Qualification has been wrongly understood as the mere absence of prescribed disqualification. Hence, it has become the bounden duty of the court to remind the Prime Minister and the Chief Minister of the State of their duty to act in accordance with the constitutional aspirations. No doubt, it is not for the court to issue any direction to the Prime Minister or the Chief Minister, as the case may be, as to the manner in which they should exercise their power while selecting the colleagues in the Council of Ministers. That is the constitutional prerogative of those functionaries who are called upon to preserve, protect and defend the Constitution. But it is the prophetic duty of this Court to remind the key duty holders about their role in working the Constitution.

Hence, I am of the firm view, that the Prime Minister and the Chief Minister of the State, who themselves have taken oath to bear true faith and allegiance to the Constitution of India and to discharge their duties faithfully and conscientiously, will be well advised to consider avoiding any person in the Council of Ministers, against whom charges have been framed by a criminal court in respect of offences involving moral turpitude and also offences specifically referred to in Chapter III of The Representation of the People Act, 1951.
