In the case of State of Haryana Vs. State of Punjab and Another, Supreme Court held:
16. …….The decisions taken at the governmental level should not be so easily nullified by a change of Government and by some other political party assuming power, particularly when such a decision affects some other State and the interest of the nation as a whole. In cannot be disputed that so far as the policy is concerned, a political party assuming power is entitled to engraft the political philosophy behind the party, since that must be held to be the will of the people. But in the matter of governance of a State or in the matter of execution of a decision taken by a previous Government, on the basis of a consensus arrived at, which does not involve any political philosophy, the succeeding Government must be held duty-bound to continue and carry on the unfinished job rather than putting a stop to the same.
It is, therefore, clear that unless it is found that the act done by the Government earlier in power is either contrary to the Constitutional provisions or unreasonable or against public interest, the State should not change its stand merely because another political party has come into power. Political agenda of an individual or a political party should not be subversive of the rule of law.
