conferred on the citizens which is sought to be interfered, such action is subject to Article 14 of the Constitution, and must be reasonable and can be taken only upon lawful and relevant grounds of public interest. Where there is arbitrariness in State action of this type of entering or not entering into contracts, Article 14 springs up and judicial review strikes such an action down. Every action of the State executive authority must be subject to rule of law and must be informed by reason. So, whatever be the activity of the public authority, in such monopoly or semi-monopoly dealings, it should meet the test of Article 14 of the Constitution. If a Governmental action even, in the matters of entering or not entering into contracts, fails to satisfy the test of reasoned ableness, the same would be unreasonable. In this connection reference may be made to E.P. Royappa v. State of Tamil Nadu , (1974) 4 SCC 3: (AIR 1974 SC 555); Maneka Gandhi v. Union of India , (1978) 1 SCC 248: (AIR 1978 SC 597), Ajay Hasia v. Khalid Mujib Sehravardi , (1981) 1 SCC 722: (AIR 1981 SC 487); R.D. Shetty v. International Airport Authority of India , (1979) 3 SCC 489: (AIR 1979 SC 162) and also Dwarkadas Marfatia and Sons v. Board of Trustees of the Port of Bombay, (1989) 3 SCC 293: (AIR 1989 SC 1642). It appears to us that rule of reason and rule against arbitrariness and discrimination, rules of fair play and natural justice are part of the rule of law applicable in situation or action by State instrumentality in dealing with citizens in a situation like the present one. Even though the rights of the citizens are in the nature of contractual rights, the manner, the method and motive of a decision of entering or not entering into. a contract, are subject to judicial review on the touchstone of relevance and reasonableness, fair play, natural justice, equality and non-discrimination in the type of the transactions and nature of the dealing as in the present case."
