Common law

[4] Common law is deeply rooted in stare decisis ("to stand by things decided"), where courts follow precedents established by previous decisions.

Oliver Wendell Holmes Jr. cautioned that "the proper derivation of general principles in both common and constitutional law ... arise gradually, in the emergence of a consensus from a multitude of particularized prior decisions".

[20] Justice Cardozo noted the "common law does not work from pre-established truths of universal and inflexible validity to conclusions derived from them deductively", but "[i]ts method is inductive, and it draws its generalizations from particulars".

In Cadillac Motor Car Co. v. Johnson[27] (decided in 1915 by the federal appeals court for New York and several neighboring states), the court held that a car owner could not recover for injuries from a defective wheel, when the automobile owner had a contract only with the automobile dealer and not with the manufacturer, even though there was "no question that the wheel was made of dead and 'dozy' wood, quite insufficient for its purposes".

The Cadillac court was willing to acknowledge that the case law supported exceptions for "an article dangerous in its nature or likely to become so in the course of the ordinary usage to be contemplated by the vendor".

Cardozo continues to adhere to the original principle of Winterbottom, that "absurd and outrageous consequences" must be avoided, and he does so by drawing a new line in the last sentence quoted above: "There must be knowledge of a danger, not merely possible, but probable."

This is the reason that judicial opinions are usually quite long, and give rationales and policies that can be balanced with judgment in future cases, rather than the bright-line rules usually embodied in statutes.

[30] At earlier stages in the development of modern legal systems and government, courts exercised their authority in performing what Roscoe Pound described as an essentially legislative function.

[44] For example, many commercial contracts are more economically efficient, and create greater wealth, because the parties know ahead of time that the proposed arrangement, though perhaps close to the line, is almost certainly legal.

Newspapers, taxpayer-funded entities with some religious affiliation, and political parties can obtain fairly clear guidance on the boundaries within which their freedom of expression rights apply.

The jury reached its verdict through evaluating common local knowledge, not necessarily through the presentation of evidence, a distinguishing factor from today's civil and criminal court systems.

At the time, royal government centered on the Curia Regis (king's court), the body of aristocrats and prelates who assisted in the administration of the realm and the ancestor of Parliament, the Star Chamber, and Privy Council.

[55][54] Eyres (a Norman French word for judicial circuit, originating from Latin iter) are more than just courts; they would supervise local government, raise revenue, investigate crimes, and enforce feudal rights of the king.

International pressure on Henry grew, and in May 1172 he negotiated a settlement with the papacy in which the King swore to go on crusade as well as effectively overturned the more controversial clauses of the Constitutions of Clarendon.

Its judges sat in open court in the Great Hall of the king's Palace of Westminster, permanently except in the vacations between the four terms of the Legal year.

Even advocates for the common law approach noted that it was not an ideal fit for the newly independent colonies: judges and lawyers alike were severely hindered by a lack of printed legal materials.

"[31] For several decades after independence, English law still exerted influence over American common law—for example, with Byrne v Boadle (1863), which first applied the res ipsa loquitur doctrine.

Many of these maxims had originated in Roman Law, migrated to England before the introduction of Christianity to the British Isles, and were typically stated in Latin even in English decisions.

Reliance on old maxims and rigid adherence to precedent, no matter how old or ill-considered, came under critical discussion in the late 19th century, starting in the United States.

[78] The degree to which these external factors should influence adjudication is the subject of active debate, but it is indisputable that judges do draw on experience and learning from everyday life, from other fields, and from other jurisdictions.

Under the old common law pleading standards, a suit by a pro se ("for oneself", without a lawyer) party was all but impossible, and there was often considerable procedural jousting at the outset of a case over minor wording issues.

[104](p6) Widely regarded as one of the most significant developments in American law, the UCC has been enacted, with some local variations, in all 50 states, the District of Columbia, Puerto Rico, and the Virgin Islands.

[105][106] An example of convergence from the other direction is shown in the 1982 decision Srl CILFIT and Lanificio di Gavardo SpA v Ministry of Health (ECLI:EU:C:1982:335), in which the European Court of Justice held that questions it has already answered need not be resubmitted.

In 1664, the colony of New York had two distinct legal systems: on Manhattan Island and along the Hudson River, sophisticated courts modeled on those of the Netherlands were resolving disputes learnedly in accordance with Dutch customary law.

Historically notable among the Louisiana code's differences from common law is the role of property rights among women, particularly in inheritance gained by widows.

The California courts have treated portions of the codes as an extension of the common-law tradition, subject to judicial development in the same manner as judge-made common law.

Roman Dutch common law jurisdictions include South Africa, Botswana, Lesotho, Namibia, Swaziland, Sri Lanka and Zimbabwe.

Edward Coke, a 17th-century Lord Chief Justice of the English Court of Common Pleas and a Member of Parliament (MP), wrote several legal texts that collected and integrated centuries of case law.

The ALI Restatements are often cited by American courts and lawyers for propositions of uncodified common law, and are considered highly persuasive authority, just below binding precedential decisions.

Scots common law covers matters including murder and theft, and has sources in custom, in legal writings and previous court decisions.
