A contract can be challenged by one of the parties to the contract if they claim their assent was not genuine because they were subject to undue influence. Undue influence is said to exist if an inordinate amount of pressure is placed upon a party to enter into a contract against their best interests. Undue influence cannot be invoked by a party simply because they are in a detrimental contract. 

Undue influence is usually only claimed in the event that the party is in a relationship wherein another person is able to influence their decisions. Normally undue influence can only be successfully claimed by a minor or an elderly person who has a guardian responsible for overseeing their legal or financial obligations.

Other relationships in which undue influence may arise include attorney-client relationships, doctor-patient relationships, and the relationships between the beneficiaries of a trust and the individual responsible for managing the trust.

An occurrence of undue influence can be difficult to establish conclusively in court. There is sometimes an automatic presumption of undue influence by the courts. A presumption of undue influence can be established if the party in the superior position influenced the dependent party to agree to a contract that benefited the superior party.

If the dependent party challenges a party that they were influenced to create by their guardian, the courts are likely to issue a presumption of undue influence because they believe that if the contract did not arise due to undue influence, then the dependent would not be challenging the contract.

The guardian involved in a court case in which the genuineness of assent in a contractual dispute involves a presumption of undue influence often bears the responsibility of disproving the charge filed against them by their ward. The undue influence charge is often repudiated by presenting evidence that the ward inquired about the terms of the contract or was afforded the opportunity to consult with an independent party that did not have a direct stake in the contractual negotiations that are being challenged.

The guardian can disprove that there has been an occurrence of undue influence even if there was a benefit conveyed to the guardian if they can demonstrate that the ward received a full disclosure of the benefit that the guardian would derive from the contract. If the guardian can prove that full disclosure was presented to the ward, that the ward obtained independent analysis of the benefits that all involved parties would receive, then the presumption of undue influence can be disproven.

In the event that undue influence is found to have existed by the courts, the courts will declare the contract to be voidable by the ward. Undue influence, however, cannot be claimed by a ward that acted upon the innocent advice of their guardian yet was harmed by the contract in a way that did not benefit the guardian.

During the contract drafting process every attention must be paid to ensuring that an illegal contract is not created. As a result, individuals responsible for contract drafting employ several safeguards to attempt to decrease the probability that they create an illegal contract.

Some of these preventative methods include using boilerplate language, which are terms used in a majority of contract drafting negotiations, as well as employing lawyers or people with a legal background in the contract drafting. However, even when these safeguards are employed, illegal contracts can still result.

Even if illegality is found to exist in a contract, it may still be enforceable in pari delicto, then a legal contract will not be ruled to exist.

If the violation of the law in question is not of a serious nature, then the illegal contract may be enforced as if it were a legal contract. If the compensation that would have to be provided in the event the contract was declared illegal would be out of proportion to the infraction of the concerned law, then the contract may be enforced as if it were a legal contract. The agreement may also be treated as a legal contract if the court determines that there would be an unjust enrichment to one of the parties in the event that the contract drafting was set aside.

If a contract is ruled to be illegal after actions have been done by one of the parties which cost money, the idea of quantum meruit may come into play. Under quantum meruit, which means “as much as deserved,” an individual may be able to recoup expenses in proportion to their outlay of money for services performed in an illegal contract if they performed the actions under the belief they were executing a legal contract.

Unlike in a legal contract, quantum meruit does not entitle the individual invoking it to hold the other person liable for the terms of the contract. This legal concept only allows the individual to recoup their losses.

Non-fraudulent misrepresentation can take one of two forms: innocent misrepresentation or negligent misrepresentation. Negligent misrepresentation is considered in the eyes of the law to contain the same level of culpability as fraudulent misrepresentation.

Misrepresentation that is negligent in nature is treated by the courts in the same way as a fraudulent misrepresentation. Negligent misrepresentation occurs when a party to a contract does not carry out a reasonable effort to ensure that their claims as the material information at the heart of the contract are true.

If one of the parties to the contract in question does not act with the professionalism that would reasonably be expected from an individual in that position, and the other party relies on that professionalism when entering into the contract, then negligent misrepresentation may be determined by the courts to have happened.

A mistake of fact which affects the genuineness of the assent given to the terms of a contract may be bilateral or unilateral. Mistakes of fact apply when the party concerned was operating under a mistaken understanding of the facts involved in the contract.

A mistake of fact is unilateral when only one party is mistaken. A bilateral mistake of fact occurs when both parties to the contract are operating under a mistaken reality. Bilateral mistakes are also known as mutual mistakes or common mistakes.

A mistake of fact that is unilateral in nature is not normally a reason to set aside a contract or a reason that will allow a plaintiff in a civil trial to seek damages. A unilateral mistake of fact will result in an enforceable voidable contract.

For example, a contract would be voidable at Luke’s discretion if Ben took advantage of Luke’s unilateral mistake regarding the purchase of a painting Luke thought was genuine. If Ben did not know that Luke thought he was buying the genuine painting, then Luke’s unilateral mistake would not prevent the contract from being enforceable.

A bilateral mistake would result in a contract that could be voided by both individuals in the event that Luke and Ben both believed the forgery was a genuine work by Dali. If Ben believed Luke intended to buy an artificial Dali painting, and Luke believed Ben was selling a genuine work by Dali, a mutual mistake has again been made because there was no intention to defraud and both parties made a mistake of fact.

Mistakes of fact should not be confused with mistakes of value. A mistake of value would occur if Jim sold Jack a random painting that he believed had only a slight value for $50. If Jim later learns that the painting was in fact done by a famous artist and worth $500, he cannot sue Jack to make up the $450. This sort of mistake is not permitted because the value of an object is not a fact. It can change. In order for a mistake to provide the basis to overturn a contract, the mistake must be of a fixed and provable nature.

 

Blue laws are a diminishing category of law in the United States. Despite being present in thirty-one states, the exact contents of each blue law varies from jurisdiction to jurisdiction. A law is classified as a blue law if it restricts commercial activity on a particular day. 

Normally a blue law prohibits the ability of a business to operate on a Sunday. The prohibition on commerce on Sunday derives from Christian religious tradition. As a result, blue laws in some states instead preclude businesses from being open on consecutive weekend days out of respect for different Sabbath observances by different religious groups.

Most states that contain blue laws apply them to the sale of alcohol. Alcohol sales may be restricted from being sold at all on Sundays. In blue law states which do not prohibit the sale of alcohol entirely on Sunday, limitations may be placed upon the hours during which alcohol may be sold. These blue law restrictions typically preclude the sale of alcohol to hours during which church sessions would not be held.

A blue law can also restrict the sale of alcohol between certain hours during the week. Restaurants in some blue law jurisdictions can obtain permits to allow the sale of alcoholic beverages so long as a particular percentage of their revenues come from food sales.

Depending on the State, towns may be allowed to opt out of observing blue laws. Some states allow local jurisdictions to opt in or out of blue laws by a majority vote. Other states restrict the ability of a local jurisdiction to opt out of blue laws based on particular criteria. In South Carolina, for example, an area can only opt out once it can demonstrate a certain level of sales tax receipts.

Blue laws may be supported for a variety of reasons. Car dealerships sometimes support blue laws because it allows them to afford their employees a day off without being concerned that a competitor is open.

There may not be support among voters to repeal blue laws. This is the situation in Bergen County in New Jersey, the only part of New Jersey with blue laws that prohibit commercial activity on Sundays. Despite pressure from the State Government to join the rest of the State in repealing blue laws, some Bergen County residents enjoy the fact that the large commercial centers in the county are relatively empty and peaceful on Sundays.

Fraud is voidable by the injured party. The justifiable reliance cannot be easily disproven and must constitute a claim that a reasonable person would believe. A promisee who entered into a contract with a car salesman that claimed that the car in the contract could go one hundred miles per gallon would not be able to claim justifiable reliance on the salesman’s claim because the claim is unjustifiable. 

The claim that a car is brand new, despite extensive and obvious damage to the car, would not be grounds for justifiable reliance by an individual claiming the salesman duped them. Justifiable reliance only applies to instances where the injured party relied upon a claim that could not be easily disproved.

A person could claim justifiable reliance if they bought a car they believed was in perfect working order but upon driving the car home discovered extensive body damage, a faulty ignition system, failing brakes, or other serious defects in the car. In such a situation, the person may be able to claim that they were damaged by a justifiable reliance on the salesman’s claims.

The party claiming that they were induced to enter into a contract due to justifiable reliance on misrepresentations by the other party must be able to show that their reliance was not based on something that they could reasonably be expected to discover on their own.

 

An unconscionable contract is unenforceable. It is immaterial whether a waiver is explicit or implicit. Procedural unconscionability also gives rise to an unconscionable contract if one of the parties is in a vastly superior bargaining position.

An unconscionable contract may also contain substantive unconscionability if the terms of the contract are excessively harsh or would be oppressive to implement. An unconscionable contract can also result if the party selling the goods marks up the price tremendously and attempts to hide how great the mark up is.

Whether a contract is conscionable or unconscionable can only be determined by a judge and never by a jury.
