70.9. The distinction between public law and private law element in the contract with the State is getting blurred. However, it has not been totally obliterated and where the matter falls purely in private field of contract, this Court has maintained the position that writ petition is not maintainable. The dichotomy between public law and private law rights and remedies would depend on the factual matrix of each case and the distinction between the public law remedies and private law field, cannot be demarcated with precision. In fact, each case has to be examined, on its facts whether the contractual relations between the parties bear insignia of public element. Once on the facts of a particular case it is found that nature of the activity or controversy involves public law element, then the matter can be examined by the High Court in writ petitions under Article 226 of the Constitution of India to see whether action of the State and/or instrumentality or agency of the State is fair, just and equitable or that relevant factors are taken into consideration and irrelevant factors have not gone into the decision-making process or that the decision is not arbitrary. 70.10. Mere reasonable or legitimate expectation of a citizen, in such a situation, may not by itself be a distinct enforceable right, but failure to consider and give due weight to it may render the decision arbitrary, and this is how the requirements of due consideration of a legitimate expectation forms part of the principle of nonarbitrariness.
