Contract law in the context of "Damages"

Ratification is a principal's legal confirmation of an act of its agent. In international law, ratification is the process by which a state declares its consent to be bound to a treaty. In the case of bilateral treaties, ratification is usually accomplished by exchanging the requisite instruments, and in the case of multilateral treaties, the usual procedure is for the depositary to collect the ratifications of all states, keeping all parties informed of the situation.

The institution of ratification grants states the necessary time-frame to seek the required approval for the treaty on the domestic level and to enact the necessary legislation to give domestic effect to that treaty. The term applies to private contract law, international treaties, and constitutions in federal states such as the United States and Canada. The term is also used in parliamentary procedure in deliberative assemblies.

In game theory, a cooperative or coalitional game is a game with groups of players who form binding "coalitions" with external enforcement of cooperative behavior (e.g. through contract law). This is different from non-cooperative games in which there is either no possibility to forge alliances or all agreements need to be self-enforcing (e.g. through credible threats).

Cooperative games are analysed by focusing on coalitions that can be formed, and the joint actions that groups can take and the resulting collective payoffs.

Offer and acceptance are generally recognized as essential requirements for the formation of a contract (together with other requirements such as consideration and legal capacity). 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.

A tort is a civil wrong, other than breach of contract, that causes a claimant to suffer loss or harm, resulting in legal liability for the person who commits the tortious act. Tort law can be contrasted with criminal law, which deals with criminal wrongs that are punishable by the state. While criminal law aims to punish individuals who commit crimes, tort law aims to compensate individuals who suffer harm as a result of the actions of others. Some wrongful acts, such as assault and battery, can result in both a civil lawsuit and a criminal prosecution in countries where the civil and criminal legal systems are separate. Tort law may also be contrasted with contract law, which provides civil remedies after breach of a duty that arises from a contract. Obligations in both tort and criminal law are more fundamental and are imposed regardless of whether the parties have a contract.

While tort law in civil law jurisdictions largely derives from Roman law, common law jurisdictions derive their tort law from customary English tort law. In civil law jurisdictions based on civil codes, both contractual and tortious or delictual liability is typically outlined in a civil code based on Roman Law principles. Tort law is referred to as the law of delict in Scots and Roman Dutch law, and resembles tort law in common law jurisdictions in that rules regarding civil liability are established primarily by precedent and theory rather than an exhaustive code. However, like other civil law jurisdictions, the underlying principles are drawn from Roman law. A handful of jurisdictions have codified a mixture of common and civil law jurisprudence either due to their colonial past (e.g. Québec, St Lucia, Mauritius) or due to influence from multiple legal traditions when their civil codes were drafted (e.g. Mainland China, the Philippines, and Thailand). Furthermore, Israel essentially codifies common law provisions on tort.

In contract law, rescission is an equitable or legal remedy which allows a contractual party to cancel the contract. Parties may rescind if they are the victims of a vitiating factor, such as misrepresentation, mistake, duress, or undue influence. Rescission is the unwinding of a transaction. This is done to bring the parties, as far as possible, back to the position in which they were before they entered into a contract (the status quo ante).

Civil law is a major "branch of the law", in common law legal systems such as those in England and Wales and in the United States, where it stands in contrast to criminal law. Private law, which relates to civil wrongs and quasi-contracts, is part of civil law, as is contract law and law of property (excluding property-related crimes, such as theft or vandalism). Civil law may, like criminal law, be divided into substantive law and procedural law. The rights and duties of persons (natural persons and legal persons) amongst themselves is the primary concern of civil law. The common law is today as fertile a source for theoretical inquiry as it has ever been. Around the English-speaking world, many scholars of law, philosophy, politics, and history study the theoretical foundations and applications of the common law. When used in the context of a common law legal system, the term civil law means that branch of the law not including criminal law.

The common law system, which originated in medieval England, is often contrasted with the civil law legal system originating in France and Italy. Whereas the civil law takes the form of legal codes such as the Napoleonic Code, the common law comes from uncodified case law that arises as a result of judicial decisions, recognising prior court decisions as legally binding precedent.

The arm's length principle (ALP) is the condition or the fact that the parties of a transaction are independent and on an equal footing. Such a transaction is known as an "arm's-length transaction". It is used specifically in contract law to arrange an agreement that will stand up to legal scrutiny, even though the parties may have shared interests (e.g., employer-employee) or are too closely related to be seen as completely independent (e.g., the parties have familial ties).

An arm's length relationship is distinguished from a fiduciary relationship, where the parties are not on an equal footing, but rather, power and information asymmetries exist. It is also one of the key elements in international taxation as it allows an adequate allocation of profit taxation rights among countries that conclude double tax conventions, through transfer pricing, among each other. Transfer pricing and the arm's length principle were one of the focal points of the base erosion and profit shifting (BEPS) model developed by the OECD and endorsed by the G20.

In the United States, state law refers to the law of each separate U.S. state.

The fifty states are separate sovereigns, with their own state constitutions, state governments, and state courts. All states have a legislative branch which enacts state statutes, an executive branch that promulgates state regulations pursuant to statutory authorization, and a judicial branch that applies, interprets, and occasionally overturns both state statutes and regulations, as well as local ordinances. States retain the power to make laws covering anything not otherwise preempted by the federal Constitution, federal statutes, or international treaties ratified by the federal Senate. Normally, state supreme courts are the final interpreters of state institutions and state law, unless their interpretation itself presents a federal issue, in which case a decision may be appealed to the U.S. Supreme Court by way of a petition for writ of certiorari. State courts regularly have concurrent jurisdiction with federal courts and, where applicable, apply or are also bound by federal law. State laws have dramatically diverged in the centuries since independence, to the extent that the United States cannot be regarded as one legal system (as to the majority of types of law traditionally under state control), but instead as 50 separate systems of tort law, family law, property law, contract law, criminal law, and so on.
