Pacta sunt servanda

Last updated

Pacta sunt servanda [1] is a brocard and a fundamental principle of law which holds that treaties or contracts are binding upon the parties that entered into the treaty or contract. [2] It is customary international law. [3] According to Hans Wehberg, a professor of international law, "few rules for the ordering of Society have such a deep moral and religious influence" as this principle. [4]

Contents

In its most common sense, the principle refers to private contracts and prescribes that the provisions, i.e. clauses, of a contract are law between the parties to the contract, and therefore implies that neglect of their respective obligations is a violation of the contract. The first known expression of the brocard is in the writings of the canonist Cardinal Hostiensis from the 13th century AD, which were published in the 16th. [5]

Modern jurisprudence

In both civil law and common law jurisdictions, the principle is related to the general principle of correct behavior in commerce, including the assumption of good faith. [6] While most jurisdictions in the world have some form of good faith within their legal systems, there exists debate as to how good faith should be evaluated and measured. [7] For example, in the United States—a common law jurisdiction—the implied duty of good faith and fair dealing exists in all commercial contracts. [8]

International law

Under international law, "every treaty in force is binding upon the parties to it and must be performed by them in good faith." [9] This entitles states party to the Vienna Convention on the Law of Treaties (signed 23 May 1969 and entered into force on 27 January 1980) to require that obligations instituted by treaties be honored and to rely on such obligations being honored. This basis of good faith for treaties implies that a party to a treaty cannot invoke provisions of its municipal (domestic) law as justification for negligence of its obligations pursuant to the treaty in question.

The only limits to application of pacta sunt servanda are the peremptory norms of general international law, which are denominated " jus cogens ", i.e. compelling law. The legal principle of clausula rebus sic stantibus in customary international law also permits non-satisfaction of obligations pursuant to treaty because of a compelling change of circumstances.

Conflict of laws is the set of rules or laws a jurisdiction applies to a case, transaction, or other occurrence that has connections to more than one jurisdiction. This body of law deals with three broad topics: jurisdiction, rules regarding when it is appropriate for a court to hear such a case; foreign judgments, dealing with the rules by which a court in one jurisdiction mandates compliance with a ruling of a court in another jurisdiction; and choice of law, which addresses the question of which substantive laws will be applied in such a case. These issues can arise in any private-law context, but they are especially prevalent in contract law and tort law.

Clausula rebus sic stantibus is the legal doctrine allowing for a contract or a treaty to become inapplicable because of a fundamental change of circumstances. In public international law the doctrine essentially serves an "escape clause" to the general rule of pacta sunt servanda. Because the doctrine is a risk to the security of treaties, as its scope is relatively unconfined, the conditions in which it may be invoked must be carefully noted.

<span class="mw-page-title-main">Commercial treaty</span>

A commercial treaty is a formal agreement between states for the purpose of establishing mutual rights and regulating conditions of trade. It is a bilateral act whereby definite arrangements are entered into by each contracting party towards the other—not mere concessions. According to Britannica, a treaty is a binding formal agreement, contract, or other written instrument that establishes obligations between two or more subjects of international law, primarily states and international organizations. The rules governing treaties between states are outlined in the Vienna Convention on the Law of Treaties (1969), while those pertaining to treaties between states and international organizations are specified in the Vienna Convention on the Law of Treaties Between States and International Organizations or Between International Organizations (1986). In essence, a treaty is a legally binding document that creates rights and responsibilities among parties. It is expected to be executed in good faith, adhering to the principle of pacta sunt servanda, which is arguably the oldest principle of international law.

<span class="mw-page-title-main">Title-transfer theory of contract</span> Legal interpretation

The title-transfer theory of contract (TTToC) is a legal interpretation of contracts developed by economist Murray Rothbard and jurist Williamson Evers. The theory interprets all contractual obligations in terms of property rights, viewing a contract as a bundle of title transfers. According to Randy Barnett, the TTToC stands in opposition to most mainstream contract theories which view contractual obligations as the result of a binding promise. Proponents of the approach often claim it is superior on grounds of both consistency and ethical considerations. The TTToC is often supported by libertarians.

In law, the principle of aut dedere aut judicare refers to the legal obligation of states under public international law to prosecute persons who commit serious international crimes where no other state has requested extradition. However, the Lockerbie case demonstrated that the requirement to extradite or prosecute is not a rule of customary international law. The obligation arises regardless of the extraterritorial nature of the crime and regardless of the fact that the perpetrator and victim may be of alien nationality. It is generally included as part of international treaties dealing with an array of transnational crimes to facilitate bringing perpetrators to justice.

Non-violation nullification of benefits (NVNB) claims are a species of dispute settlement in the World Trade Organization arising under World Trade Organization multilateral and bilateral trade agreements.
