In law, derogation is the temporary and partial setting aside of a legal rule or contractual obligation without repealing it. The underlying law stays on the books and keeps applying to everyone else; the derogation carves out a narrow exception for a specific situation, group, or period. Governments invoke it during emergencies to relax certain human rights protections. Businesses use derogation clauses to swap out default statutory rules for terms that fit their deal. Every legal system that allows it also draws hard lines around what cannot be touched.
That is the short version of the derogation meaning in law. The longer answer depends on whether you are looking at a treaty, a federal emergency statute, or a commercial contract, because the mechanics and the limits differ in each setting.
Derogation, Abrogation, and Amendment
Derogation is not repeal. Abrogation ends a law entirely. Amendment permanently rewrites its text. Derogation leaves the rule intact and suspends or relaxes it for a defined purpose and time.
A related maxim, lex posterior derogat legi priori, holds that when a newer law conflicts with an older one, the newer law controls. It functions as a kind of automatic derogation: the earlier rule loses its force wherever it clashes with the later enactment, even if nobody formally repealed it.
Derogation in International Human Rights Law
The most consequential use of derogation is when a government suspends certain human rights protections during a national crisis. Two treaties set the framework.
Article 15 of the European Convention on Human Rights allows a member state to take measures deviating from its treaty obligations “in time of war or other public emergency threatening the life of the nation,” but only “to the extent strictly required by the exigencies of the situation.”1European Court of Human Rights. European Convention on Human Rights The emergency must be genuine and severe enough to threaten the organized life of the community. Any measures must also be consistent with the state’s other international obligations.
Article 4 of the International Covenant on Civil and Political Rights is parallel. A state party may derogate during a publicly proclaimed emergency that threatens the life of the nation, so long as the measures go no further than the situation demands, remain consistent with other international obligations, and do not discriminate solely on the basis of race, color, sex, language, religion, or social origin.2Office of the High Commissioner for Human Rights. International Covenant on Civil and Political Rights The non-discrimination requirement is broader here than under the ECHR.
Declaring an emergency does not give a government a blank check. The European Court of Human Rights applies a “margin of appreciation,” recognizing that national authorities are better placed to judge whether a genuine emergency exists and what steps it demands. But the court retains the power to decide whether the measures actually taken went beyond what the crisis required.3Council of Europe Parliamentary Assembly. Proportionality Issues Concerning Derogations Under Article 15 Necessity, proportionality, non-discrimination, respect for non-derogable rights, and proper notification are the tests it looks at.
Rights That Cannot Be Derogated
Both treaties draw a hard line around certain rights that no emergency can reach. This is the single most important limit on the doctrine.
Under Article 4(2) of the ICCPR, no derogation is permitted from the right to life (Article 6), the prohibition of torture and cruel treatment (Article 7), the prohibition of slavery and servitude (Article 8, paragraphs 1 and 2), the ban on imprisonment for inability to fulfill a contract (Article 11), the principle that criminal law cannot be applied retroactively (Article 15), the right to recognition as a person before the law (Article 16), and freedom of thought, conscience, and religion (Article 18).2Office of the High Commissioner for Human Rights. International Covenant on Civil and Political Rights
The ECHR list in Article 15(2) is similar but shorter: the right to life (except for deaths resulting from lawful acts of war), the prohibition of torture, the prohibition of slavery, and the principle that there is no punishment without law.4European Court of Human Rights. Factsheet – Derogation in Time of Emergency A government that suspended fair trial rights during a crisis would still be absolutely prohibited from torturing detainees or executing people without legal basis.
How the Concept Appears in U.S. Law
The United States does not use the word “derogation” in its domestic statutes, but the same idea runs through federal law under labels like waivers, suspensions, and emergency relief.
Habeas Corpus
The clearest constitutional example is in Article I, Section 9: the privilege of the writ of habeas corpus “shall not be suspended, unless when in Cases of Rebellion or Invasion the public Safety may require it.”5Legal Information Institute. Writ of Habeas Corpus and the Suspension Clause The right continues to exist; its enforcement can be set aside only under strictly defined conditions.
National Emergencies and Healthcare Waivers
The National Emergencies Act does not create new presidential powers. It sets the procedure for activating emergency authorities scattered across other statutes. A declaration must specify which authorities are being invoked, and it expires automatically after one year unless the president formally renews it.6Congress.gov. National Emergency Powers
One of the most heavily used authorities is 42 U.S.C. § 1320b-5, which lets the Secretary of Health and Human Services waive or modify federal healthcare requirements during a declared emergency. Waivers can cover provider licensing across state lines, certain patient-transfer rules, telehealth restrictions, specific HIPAA privacy requirements, and physician referral limitations.7Office of the Law Revision Counsel. 42 USC 1320b-5 – Authority to Waive Requirements During National Emergencies
Disaster Relief
After a major disaster declaration, federal agencies can waive administrative conditions on assistance programs when the inability to meet those conditions results from the disaster itself, under the Stafford Act.8Office of the Law Revision Counsel. 42 USC Chapter 68 – Disaster Relief The president can also waive fees for replacing critical documents like passports, permanent resident cards, and employment authorization forms for affected households. When FEMA declares a disaster, the IRS automatically extends filing and payment deadlines for taxpayers whose address of record is in the disaster zone.9Internal Revenue Service. Tax Relief in Disaster Situations
Derogation in Commercial Contracts
Outside the world of emergencies, derogation is a routine feature of business contracts. Most commercial statutes are “dispositive”: they supply default rules that apply only when the parties have not agreed to something different. A derogation clause replaces a default with a custom term.
Parties to a loan agreement might set a different interest calculation than the statutory default. A master service contract might cap liability at a fixed dollar amount rather than leave it open under general tort principles. This flexibility is the backbone of commercial law.
Force Majeure
Force majeure clauses are a specific type of derogation, excusing a party from performance when extraordinary events make it impossible or impracticable. The Uniform Commercial Code codifies a version for sales of goods. Under UCC § 2-615, a seller is excused from timely delivery if performance has been made impracticable by an event the parties assumed would not happen, such as a natural disaster destroying a supplier’s factory or a government order shutting a plant.10Legal Information Institute. UCC 2-615 – Excuse by Failure of Presupposed Conditions The seller must notify the buyer seasonably, and if production is limited, must allocate deliveries fairly among customers.
Well-drafted force majeure clauses go further than the UCC baseline, specifying which events qualify (pandemics, government shutdowns, cyberattacks), the notice deadline, and what obligations survive during the suspension. Poorly drafted ones lead to expensive litigation over what counts as “beyond the parties’ control.”
What Contracts Cannot Derogate
Freedom of contract has hard limits. Certain statutory protections are mandatory or non-waivable: no private agreement can override them regardless of what the parties signed.
The Fair Labor Standards Act is the clearest federal example. Employers cannot use an employment agreement to pay below the federal minimum wage or to avoid overtime. Even deductions the employee technically agrees to are unlawful if they push effective pay below the minimum wage or reduce required overtime compensation.11U.S. Department of Labor. Handy Reference Guide to the Fair Labor Standards Act If workers could waive these protections, the protections would be worthless, since the power imbalance in most employment relationships would effectively make waivers mandatory.
Similar non-waivable protections run through consumer law. Warranty disclaimers that violate the Magnuson-Moss Warranty Act, arbitration clauses that block consumers from pursuing statutory claims, and terms purporting to waive rights under lending or credit statutes all face judicial scrutiny and potential invalidation.
Notification Is Part of the Rule
A derogation does not take effect in silence. Both treaty frameworks and commercial contracts impose notification obligations that, if ignored, can invalidate the derogation.
Under Article 4(3) of the ICCPR, a state invoking a derogation must immediately inform other state parties, through the UN Secretary-General, of the specific provisions being derogated and the reasons. A second communication is required on the date the derogation ends.2Office of the High Commissioner for Human Rights. International Covenant on Civil and Political Rights The ECHR imposes a parallel requirement through Article 15(3), directing the derogating state to keep the Secretary General of the Council of Europe “fully informed” of the measures and the reasons for them.1European Court of Human Rights. European Convention on Human Rights The UN Treaty Handbook confirms that notifications must identify the specific provisions affected and explain the reasons, with separate notifications required when the emergency is extended or terminated.12United Nations Treaty Collection. Treaty Handbook
In private contracts, the procedure depends on what the agreement says. Most force majeure and derogation provisions specify the method of notice, the required content (the triggering event, obligations affected, expected duration), and the deadline. Under the UCC the standard is seasonable notice: within a commercially reasonable time after the triggering event.10Legal Information Institute. UCC 2-615 – Excuse by Failure of Presupposed Conditions Courts routinely hold that a party who waited too long, sent notice to the wrong address, or failed to describe the triggering event with enough specificity has forfeited the right to claim excuse. If your contract has a force majeure or derogation clause, read the notice provision before you need it.
Derogation in Practice
The pandemic produced the largest wave of derogation notifications in the history of the European Convention. Ten countries formally notified the Council of Europe of derogations under Article 15: Albania, Armenia, Estonia, Georgia, Latvia, North Macedonia, Moldova, Romania, San Marino, and Serbia.13Council of Europe. Derogations Covid-19 Several submitted multiple notifications as measures were extended, modified, or lifted. Most of these derogations targeted freedom of movement and assembly, not the non-derogable core rights.
Ukraine notified the Council of Europe of derogations covering several Convention articles after Russia’s invasion in February 2022, then progressively narrowed the scope. By April 2024, Ukraine had withdrawn derogations from provisions covering forced labor, freedom of thought and religion, the right to an effective remedy, the prohibition of discrimination, and restrictions on the political activity of aliens.14Council of Europe. Ukraine – Derogations From the European Convention on Human Rights As certain emergency conditions eased, the corresponding derogations were rolled back, even while the armed conflict continued. That is the proportionality principle in action, and it is what separates a lawful derogation from a permanent loss of rights.
