If a contract is reasonable and fair at first, but there have been circumstances that show that it is applied by one party in a way that harms the interests of others, the courts will find the agreement unenforceable. Although not valid or invalid. This opinion was expressed by the Court of Appeal in Shell UK Ltd/Lostock Garages Ltd. An agreement to do an impossible act in itself is a null and void. Empty agreements are agreements that are not enforced by the courts. Section 2 (g) of the Indian Contract Act defines an inconclusive agreement as “an agreement that is not legally applicable.” Therefore, in the event of an inconclusive agreement, there is no recourse to the contracting parties. Thus, in a case where a person has promised to pay his brother`s debts, although it is not based on valuable counterparties, but it is a good reflection because of love, affection, if, made by the recorded document. If a girl takes care of her father, takes care of him and, in return, if he gives him something, she will fall under that section. Therefore, any agreement that imposes restrictions on a trader`s choice of mode of activity is void. In this section, it is stated that if the consideration or objective of the contract is totally or partially illegal, the agreement must be considered inconclusive.
The working philosophy underlying this section is that if the illegal clause can be dissociated from the contract, then the whole contract is not considered invalid, but only the illegal part is considered invalid and the rest of the contract is considered valid, but if the illegal clause cannot be dissociated from the legal part, then the whole contract is considered illegal.  An act contract that becomes impossible after the contract is concluded or because of an event that the promiseor could not prevent becomes invalid if the act becomes impossible or illegal. An example of non-agreement by uncertainty is an example that is vaguely formulated: “X agrees to buy Y fruit.” If it is not possible to determine what type of fruit has been agreed or contemplated, the agreement is void. However, if Part Y is a grapefruit producer in the previous agreement, there is a clear indication of the type of fruit envisaged and X would remain suitable for purchase. A non-law contract is a formal agreement that is virtually illegitimate and unenforceable from the time it is concluded.
