Quasi Contract

When a party receives a benefit or advantage from another party by mistake or under circumstances where no formal contract exists, a quasi contract may be formed. It is a legal concept that aims to prevent unjust enrichment or unfairness to either party involved. In the given scenario, A delivered goods to B's warehouse by mistake, and B used the goods. A subsequently asks B for the price of the goods. This situation can be categorized as a quasi contract.

Explanation

Definition of a Quasi Contract
A quasi contract is a legal fiction that is imposed by the court to prevent one party from unfairly benefiting at the expense of another party. It is not a true contract, as it lacks the mutual consent of the parties, but it is enforced to prevent unjust enrichment.

Elements of a Quasi Contract
To establish a quasi contract, certain elements must be present:

1. Benefit Received: One party must have received a benefit or advantage from another party.

In this scenario, B received the goods delivered by A, which can be considered a benefit.

2. Mistake or Lack of Contract: The benefit must have been received by mistake or under circumstances where no formal contract exists.

A mistakenly delivered the goods to B's warehouse, and there was no formal contract between A and B for the goods.

3. Unjust Enrichment: It must be unfair for the party receiving the benefit to retain it without compensating the other party.

In this case, if B were to keep the goods without compensating A, it would result in unjust enrichment for B.

Application to the Given Scenario
In the given scenario, A delivered goods to B's warehouse by mistake, and B used the goods. As there was no formal contract between A and B, and B received a benefit from A's mistake, A has the right to ask B for the price of the goods under the concept of a quasi contract.

Conclusion
A quasi contract is a legal concept that aims to prevent unjust enrichment or unfairness to either party involved. In the given scenario, A delivered goods to B's warehouse by mistake, and B used the goods. As there was no formal contract between A and B, A can ask B for the price of the goods under the concept of a quasi contract.
