‘Nemo locupletari potest aliena iactura’ means no one should be a benefit at others expense in other words it means Unjust Enrichment. Unjust Enrichment means that due to the loss of an individual others should not gain any benefit. One should not be enriched on the loss of another as it will be unjust to that person. It means retention of a property or goods and commodity of others is against the basic principle of Justice as it would be unjust to the other party. It means if A is providing something to B then B should also provide something in return. The gift does not come under unjust enrichment as it is without any expectation of anything in return.
Section 68 of the Indian Contract Act states that ‘Claim for necessaries supplied to person incapable of contracting, or on his account’. If a person, incapable of entering into a contract, or anyone whom he is legally bound to support, is supplied by another person with necessaries suited to his condition in life, the person who has furnished such supplies is entitled to be reimbursed from the property of such incapable person. It means that – if a person if ‘A’ is supplying some goods to ‘K’ which are necessary for nature then A is entitled to recover the monetary compensation for supplying the goods to K or from K’s property. It means that if someone is getting benefited at the cost of others then he has to return the benefit otherwise it will be unjust benefit or enrichment.
Moses v. Macferlan
Jacob has given promissory notes to Moses and Moses used and endorsed the said promissory notes to Macfarlan as Moses owed money with an agreement that Moses will have no personal liability on the notes. Despite the agreement, Macfarlan sued Moses on the endorsement. And through arbitration Moses has to pay money to Macfarlan even when Moses has no personal liability. Therefore, Moses sued Macfarlan in court to recover the money. The court held that Macfarlan needs to return the money to Moses for equity and natural justice. If not then it will be unjust enrichment to one party. The above case law established the principle of Unjust Enrichment.
Unjust Enrichment and Restitution
They both belong to grey with different shades. It means that Restitution means restoration of property or object to the original owner if obtain through Malafide means. Though the goods or commodity needs to be traceable. Section 65. The obligation of a person who has received advantage under the void agreement, or contracts that become void. When an agreement is discovered to be void, or when a contract becomes void, any person who has received any advantage under such agreement or contract is bound to restore it or to make compensation for it to the person from whom he received it. It means that they have to restore it to its original position or provide compensation for the benefits received by them to the original owner. If not then it will be unjust enrichment to one party while the other Party will suffer loss.
Quasi-Contract means those contracts which are created by Courts rather than normal relations and are done to dispense justice and to otherwise it will be unjust retention and unjust enrichment of Property. Quasi-Contract is different from the normal contract as there is no offer or prior agreement to form a contract or acceptance by the parties and it is made at the direction of the court. In a Contract, free consent is necessary to form a contract while in Quasi Contract there is no consent by either of the Parties. In Quasi-Contract conduct of the parties who are part of the contract decides the liability and is decided on the basis of natural justice and equity while in the Contract the liabilities of the parties are already decided with the terms of the Contract. Quasi-Contracts are imposed by the courts in India. In India, the Indian Contract Act 1872 does not specifically mention Quasi-Contract However Chapter five of the Act deals with certain relations resembling those created by Contract. It means relations that look like a contract but they are in reality, not contracts. Section 68-72 deals with Quasi-Contracts.
“68. Claim for necessaries supplied to person incapable of contracting, or on his account. If, a person, incapable of entering into a contract, or anyone whom he is legally bound to support, is supplied by another person with necessaries suited to his condition in life, the person who has furnished such supplies is entitled to be reimbursed from the property of such incapable person.” If necessary items are supplied to an unsound person who is incapable of making a contract then the person supplying is entitled to receive money for the commodities so supplied, from the property of the person. The necessaries differ in different cases and are decided by the courts
“69. Reimbursement of person paying money due by another, in payment of which he is interested. A person who is interested in the payment of money which another is bound by law to pay, and who therefore pays it, is entitled to be reimbursed by the other.” Section 69 forms Quasi-Contract between the parties. The essentials of this section is The Party paying the money needed to have interest on the payment for other parties. The other party was imposed by the government to pay the dues.

Quasi Contracts are not actual contracts in the Indian Contracts Act but there is a certain obligation possessed by it as chapter five of the Indian Contract Act 1872 does deal with relations that resemble Contract. It is imposed by law so as to not unjustly benefit others. The Doctrine of Unjust Enrichment has been evolved over time the Courts have also started using it in wider concepts not only in Contracts but also in Taxes. In situations where taxes have been appropriated wrongly.
