For example, some jurisdictions allow prosecution for negligent infliction of emotional distress even if the plaintiff is not physically injured, but most do not. For a particular offence, States differ in the means, nature and scope of remedies, limitation periods and the extent of the specificity with which the cause must be invoked. In virtually all aspects of tort law, there is a “majority rule” observed by most States and one or more “minority rules”. Today, in the words of Stanford law professor Lawrence M. Friedman: “American affairs rarely cite foreign documents. Courts sometimes cite one or two British classics, an old famous case or an allusion to Blackstone; But the current British law is almost never mentioned.  Foreign law has never been cited as a binding precedent, but as a reflection of the common values of Anglo-American civilization or even Western civilization in general.  Suppose the court decides that Smith owns the barn he built and now owns the small portion of the land it occupies. That is now the rule that applies to the cases that come after Smith and Jones. From that point on, all landowners must be careful not to allow others to build permanent facilities on their land. Otherwise, the rule now says they could lose ownership of that part of their land. Scenarios like this led to a gradual development of a vast system of laws, even though those rules were mostly unwritten at the time.
Cases are legal decisions based on a specific set of facts involving parties who have a real interest in the controversy. There are specific ethical rules applicable to these matters, but in most cases, when the interests of the client and those of the lawyer as an officer of the court conflict or interfere with each other, the lawyer is generally expected to promote his or her role as counsel for the client. The American democratic system is not always based on the simple majority rule. Certain principles are so important to the nation that the majority has agreed not to interfere in these areas. For example, the Bill of Rights was adopted because concepts such as freedom of religion, freedom of expression, equal treatment and due process were considered so important that even a majority should not be allowed to change them. Congress often passes legislation that gives federal agencies broad regulatory powers. Often, Congress is simply too bogged down to draft detailed statutes explaining how the agency should respond to every possible situation, or Congress believes that the agency`s technical specialists are best equipped to deal with certain factual situations as they arise. Therefore, federal organizations have the authority to make regulations.
Under the principle of chevron reverence, regulations generally have the force of law as long as they are based on a reasonable interpretation of the relevant statutes.  Criminal procedure law in the United States consists of a massive overlay of federal constitutional jurisprudence intertwined with federal and state laws, which in fact form the basis for the creation and operation of law enforcement agencies and prison systems, as well as procedure in criminal trials. Due to the perpetual inability of U.S. lawmakers to enact laws that would effectively compel law enforcement officials to respect the constitutional rights of suspects and convicts, the federal judiciary has gradually developed the exclusionary rule as a method of enforcing those rights.  In turn, the exclusionary rule has spawned a family of remedies created by judges against abuse of law enforcement powers, the most famous of which is the Miranda Warning. The habeas corpus warrant is often used by suspects and convicts to challenge their detention, while the Third Enforcement and Bivens Measures Act is used by suspects to obtain damages for police brutality. Regulations are published in accordance with the Administrative Procedure Act (APA). Regulations are first proposed and published in the Federal Register (FR or Fed. Reg.) and are subject to a public comment period. Finally, after a deadline for public comments and revisions based on comments received, a final version will be published in the Federal Register.
