Resignation is to set aside a contract or terminate a contract. There are four different ways to set aside contracts. A contract can be described as „zero,” „zero” or „unworkable” or „inoperative.” The void implies that no contract has ever been concluded. Nullity implies that one or both parties may, according to their own response, declare that a contract is inoperative. Homicide fees are paid by magazine publishers to authors if their articles are submitted without notice, but are not used for publication. In this case, the magazine cannot claim any copyright for the „killed” task. the impossibility of inapplicability implies that neither party is in a position to remedy the situation. There are trade relationships that give the impression that a legally binding agreement has been reached. However, if the test for terminating the contract is not met, there cannot be a contract.
Arbitration decisions can generally be enforced in the same way as ordinary court decisions and are internationally recognized and enforceable under the 156-party New York Convention. In the states of the New York Convention, arbitration decisions are generally immunized, unless there is a document proven that the arbitrator`s decision was irrational or tainted by fraud.  Statements contained in a contract cannot be upheld if the court finds that the statements are subjective or advertising. English courts may balance the emphasis or relative knowledge to determine whether a declaration is applicable under the contract. In the English Case of Bannerman/White, the Tribunal upheld a refusal of the sulphur-treated hops, as the purchaser expressly expressed the importance of this requirement. Relative knowledge of the parties may also be a factor, as in the English case Bissett/Wilkinson, where the court found no misrepresentation when a seller stated that the sale of arable land would carry 2000 sheep if dealt with by a team; the buyer was considered competent enough to accept or reject the seller`s opinion. Statements can be made before the drafting of the contract, there may be misunderstandings that undermine the legally binding nature of the treaty. Second, one of the parties could mislead its opponent (knowingly or not) with respect to a fact, the state of the situation or the length of the contract. In the United States, an unusual type of unworkable contract is a personal employment contract to work as a spy or secret agent. Indeed, the secret of the contract is a condition of the contract (to maintain plausible denial).
If the spy then sues the government for issues such as salary or benefits, the spy violated the contract by revealing its existence. It is therefore unenforceable for this reason, as is the public policy of maintaining national security (because an angry officer might try to reveal all the secrets of the government during his complaint).  Other types of non-opposable employment contracts include contracts that agree to work for less than the minimum wage and lose the right to workers` compensation in cases where compensation is due.
