State of Rajasthan v. Basant Nahata, AIR 2005 (SC) 3401 it would not, in our opinion, be correct to contend that public policy is capable of being given a precise definition. What is 'opposed to public policy' would be a matter depending upon the nature of the transaction. The pleadings of the parties and the materials brought on record would be relevant so as to enable the court to judge the concept as to what is for public good or in the public interest or what would be injurious or harmful to the public good or the public interest at the relevant point of time as contra-distinguished from the policy of a particular government. A law dealing with the rights of a citizen is required to be clear and unambiguous. Doctrine of public policy is contained in a branch of common law, it is governed by precedents. The phraseology 'opposed to public policy' may embrace within its fold such acts which are likely to deprave, corrupt or injurious to the public morality and, thus, essentially should be a matter of legislative policy. 63. Hence, it becomes amply clear that it is not possible to define Public policy with precision at any point of time. It is not for the executive to fill these gray areas as the said power rests with judiciary. Whenever interpretation of the concept "public policy" is required to be considered it is for the judiciary to do so and in doing so even the power of the judiciary is very limited. 70. So far as amendments made by other States are concerned, we are of the opinion that any order passed by a Sub-Registrar or Registrar refusing to register a document pursuant to any notification issued under Section 22-A of the Act would not be reopened.
