An agreement on the execution of an illegal act is an example of non-agreement. For example, a contract between dealers and buyers is a non-contract, simply because the terms of the contract are illegal. In such a case, neither party can take legal action to enforce the contract. An inconclusive contract is invalid from the outset, while a cancelled contract may be cancelled by one or all parties. A cancelled contract is not invalidated by initio, but becomes invalidated later due to certain changes in the condition. In summary, the contracting parties do not have discretion in a nullity contract. Contracting parties are not entitled to enforce a nullity contract.  A non-contract contract cannot be imposed by law. Void contracts are different from cancelled contracts, which are contracts that can be cancelled.
However, when a contract is written and signed, there is no automatic mechanism in each situation that can be used to determine the validity or applicability of that contract. In practice, a contract can be cancelled by a court.  The main question, then, is under what conditions can a contract be considered inconclusive? A contract may also be cancelled due to the impossibility of its performance. Like what. B if a contract is entered into between two parties A-B, but it is no longer possible to obtain the subject matter of the contract during the performance of the contract (due to the action of someone or other than the contracting parties), the contract cannot be obtained in court and is therefore unfagreested.  A void contract may be a contract in which one of the terms of a valid contract is absent/absent, for example.B. in the absence of contractual capacity, the contract may be considered null and void. In fact, it is not the case, it is that there is no contract. The law cannot impose any legal obligation on any of the parties, especially the disappointed party, because they are not entitled to contract protection laws.
