The doctrine of privity of contract is a common law principle which provides that a contract cannot confer rights or impose obligations upon anyone who is not a party to that contract. It is related to, but distinct from, the doctrine of consideration, according to which a promise is legally enforceable only if valid consideration has been provided for it, and a plaintiff is legally entitled to enforce such a promise only if they are a promisee from whom the consideration has moved.
Unconscionability is a doctrine in contract law that describes terms that are so extremely unjust, or overwhelmingly one-sided in favor of the party who has the superior bargaining power, that they are contrary to good conscience. Typically, an unconscionable contract is held to be unenforceable because no reasonable or informed person would otherwise agree to it. The perpetrator of the conduct is not allowed to benefit, because the consideration offered is lacking, or is so obviously inadequate, that to enforce the contract would be unfair to the party seeking to escape the contract.
Offer and acceptance are generally recognized as essential requirements for the formation of a contract. Analysis of their operation is a traditional approach in contract law. This classical approach to contract formation has been modified by developments in the law of estoppel, misleading conduct, misrepresentation, unjust enrichment, and power of acceptance.
Felthouse v Bindley [1862] EWHC CP J35, is the leading English contract law case on the rule that one cannot impose an obligation on another to reject one's offer. This is sometimes misleadingly expressed as a rule that "silence cannot amount to acceptance".
Balfour v Balfour [1919] 2 KB 571 is a leading English contract law case. It held that there is a rebuttable presumption against an intention to create a legally enforceable agreement when the agreement is domestic in nature.
Pharmaceutical Society of Great Britain v Boots Cash Chemists (Southern) Ltd [1953] EWCA Civ 6 is a famous English contract law decision on the nature of an offer. The Court held that the display of a product in a store with a price attached is not sufficient to be considered an offer, and upheld the concept of an invitation to treat.
Smith v Hughes (1871) LR 6 QB 597 is an English contract law case. In it, Blackburn J set out his classic statement of the objective interpretation of people's conduct when entering into a contract. The case regarded a mistake made by Mr. Hughes, a horse trainer, who bought a quantity of oats that were the same as a sample he had been shown. However, Hughes had misidentified the kind of oats: his horse could not eat them, and he refused to pay for them. Smith, the oat supplier, sued for Hughes to complete the sale as agreed. The court sided with Smith, as he provided the oats Hughes agreed to buy. That Hughes made a mistake was his own fault, as he had not been misled by Smith. Since Smith had made no fault, there was no mutual mistake, and the sale contract was still valid.
Rose & Frank Co v JR Crompton & Bros Ltd [1924] is a leading decision on English contract law, regarding the intention to create legal relations in commercial arrangements. In the Court of Appeal, Atkin LJ delivered an important dissenting judgment which was upheld by the House of Lords.
Sherwood v. Walker, 66 Mich. 568, 33 N.W. 919, was a case that has played an important role in the evolution of American contract law involving the doctrine of mutual mistake. One of the main issues in the case was whether the remedy of rescission is available if both parties to a contract share a misunderstanding about an essential fact. Commonly referred to as the "Pregnant Cow Case," the case is a staple of first-year law school contract law class discussions and textbooks and has been briefed extensively online.
Quanta Computer, Inc. v. LG Electronics, Inc., 553 U.S. 617 (2008), is a case decided by the United States Supreme Court in which the Court reaffirmed the validity of the patent exhaustion doctrine. The decision made uncertain the continuing precedential value of a line of decisions in the Federal Circuit that had sought to limit Supreme Court exhaustion doctrine decisions to their facts and to require a so-called "rule of reason" analysis of all post-sale restrictions other than tie-ins and price fixes. In the course of restating the patent exhaustion doctrine, the Court held that it is triggered by, among other things, an authorized sale of a component when the only reasonable and intended use of the component is to engage the patent and the component substantially embodies the patented invention by embodying its essential features. The Court also overturned, in passing, that the exhaustion doctrine was limited to product claims and did not apply to method claims.
Hochster v De La Tour[1853] EWHC J72 (QB) is a landmark English contract law case on anticipatory breach of contract. It held that if a contract is repudiated before the date of performance, damages may be claimed immediately.
Cutter v Powell (1795) 101 ER 573 is an English contract law case, concerning substantial performance of a contract.
Robert Cooper Grier was an American jurist who served on the Supreme Court of the United States.
Intention to create legal relations, otherwise an "intention to be legally bound", is a doctrine used in contract law, particularly English contract law and related common law jurisdictions.
Cooper Manufacturing Co. v. Ferguson, 113 U.S. 727 (1885), was a suit regarding the legitimacy of a sale of a steam engine and other machinery in the State of Ohio.
Dickinson v Dodds (1876) 2 Ch D 463 is an English contract law case heard by the Court of Appeal, Chancery Division, which held that notification by a third party of an offer's withdrawal is effective just like a withdrawal by the person who made an offer. The significance of this case to many students of contract law is that a promise to keep an offer open is itself a contract which must have some consideration.
Re Goldcorp Exchange Ltd [1994] UKPC 3 is an English trusts law case by the Judicial Committee of the Privy Council decision on appeal from the Court of Appeal of New Zealand. It considers when there is sufficient certainty of subject matter to form a trust, and tracing. A company dealing in gold and other precious metals became insolvent and the Bank of New Zealand appointed receivers under a debenture. They in turn asked the High Court for guidance on how to treat the company's customers, and Thorp J refused the claims of most of the customers, leaving three categories to be settled on appeal. The outstanding issue was whether the customers had title to the gold on for them, and thus beneficiaries of a trust, or were merely unsecured creditors resulting from a breach of contract.
Robinson v Randfontein Estates Gold Mining Co Ltd is an important case in South African law. It was heard in the Appellate Division from 13 to 20 December 1920, with judgment handed down on 19 February 1921. Innes CJ, Solomon JA, CG Maasdorp JA, Juta JA and Bristowe AJA presided.
CIBC Mortgages plc v Pitt[1993] UKHL 7 is a decision of the House of Lords relating to undue influence. The decision confirmed that a person did not need to suffer "manifest disadvantage" under a transaction in order to challenge it for actual undue influence.
Welsh Development Agency v Export Finance Co Ltd [1992] BCLC 148 is a judicial decision of the English Court of Appeal. The decision related to a number of aspects relating to complex financing arrangement, but is most often cited for the decision in relation to recharacterisation.
