Injunction: the story on HearLore | HearLore
Injunction
An injunction is not merely a suggestion; it is a court order backed by the full coercive powers of the state, capable of sending a non-compliant party to prison. This legal mechanism, developed by English courts of equity with roots stretching back to Roman law, compels a party to act or refrain from acting under the threat of criminal or civil penalties. When a court employs this extraordinary remedy, it directs the conduct of a party with the backing of its full coercive powers, as noted in the 2009 Supreme Court case Nken v. Holder. Failure to comply with such an order does not result in a simple fine; it can lead to imprisonment and charges of contempt of court. The rationale behind this power lies in the doctrine that an injunction is granted only when there is no adequate remedy at law, meaning money damages cannot effectively fix the wrong. It is designed to make whole again someone whose rights have been violated, while courts simultaneously weigh the public interest and the fairness of the situation. This balance ensures that the remedy is not abused, subjecting it to equitable defenses like laches and unclean hands.
Labor Wars and School Desegregation
In the late nineteenth and early twentieth century, federal courts wielded injunctions as weapons to break strikes by unions, fundamentally altering the landscape of American labor relations. Following the United States government's successful use of an injunction to outlaw the Pullman boycott in 1894, employers discovered they could obtain federal court orders to ban strikes and organizing activities of all kinds. One injunction issued by a federal court in the 1920s effectively barred the United Mine Workers of America from talking to workers who had signed yellow dog contracts with their employers. Unable to limit what they called government by injunction, labor and its allies persuaded the United States Congress in 1932 to pass the Norris-LaGuardia Act, which imposed so many procedural and substantive limits on the federal courts' power to issue injunctions that it effectively prohibited federal courts from issuing injunctions in cases arising out of labor disputes. Decades later, injunctions became crucial to the second half of the twentieth century in the desegregation of American schools. Federal courts gave injunctions that carried out the command of Brown v Board of Education to integrate public schools, and at times courts took over the management of public schools to ensure compliance. An injunction that puts a court in the position of taking over and administering an institution, such as a school, a prison, or a hospital, is often called a structural injunction.
What is an injunction and how does it differ from a suggestion?
An injunction is a court order backed by the full coercive powers of the state, capable of sending a non-compliant party to prison. This legal mechanism compels a party to act or refrain from acting under the threat of criminal or civil penalties. Failure to comply with such an order can lead to imprisonment and charges of contempt of court.

What are the three main forms of injunctions in the United States?
In the United States, injunctions tend to come in three main forms: temporary restraining orders, preliminary injunctions, and permanent injunctions. A temporary restraining order is a special kind of injunction that may be issued before trial, sometimes without notice to the other party or a hearing. A preliminary injunction is given before trial, and a permanent injunction is issued after trial.
What is a super-injunction and when was the term coined?
Super-injunctions are injunctions whose existence and details may not be legally reported, in addition to facts or allegations which may not be disclosed. Roy Greenslade credits the former editor of The Guardian, Alan Rusbridger, with coining the word super-injunction in an article about the Trafigura affair in September 2009. An example was the super-injunction raised in September 2009 by Carter-Ruck solicitors on behalf of oil trader Trafigura, prohibiting the reporting of an internal Trafigura report into the 2006 Ivory Coast toxic waste dump scandal.
How do injunctions apply to standard-essential patents in the United States?
The Department of Justice and the Federal Trade Commission have investigated patent holders in the United States for seeking preliminary injunctions against accused infringers of standard-essential patents. There is an ongoing debate among legal and economic scholars with major implications for antitrust policy in the United States as well as in other countries over the statutory limits to the patent holder's right to seek and obtain injunctive relief against infringers of standard-essential patents.
What happened in 2025 regarding oral directives and injunctions in the United States?
In 2025, the legal landscape of injunctions faced a new and controversial test when United States Attorney General Pam Bondi and other Justice Department officials argued in a court filing that an oral directive is not enforceable as an injunction. This argument arose after the second Trump administration completed deportation flights despite a federal judge verbally ordering the flights to be returned to the United States. The case highlighted the tension between the traditional understanding of injunctions as written court orders and the practical realities of modern administrative enforcement.
In the United States, injunctions tend to come in three main forms, each serving a distinct purpose in the timeline of a legal dispute. A temporary restraining order is a special kind of injunction that may be issued before trial, sometimes without notice to the other party or a hearing. A temporary restraining order will be given only for a short period of time before a court can schedule a hearing at which the restrained person may appear and contest the order. If the temporary restraining order is contested, the court must decide whether to issue a preliminary injunction. These are given before trial, and because they are issued at an early stage before the court has heard the evidence and made a decision in the case, they are more rarely given. The requirements for a preliminary injunction tend to be the same as for a permanent injunction, with the additional requirement that the party asking for the injunction is likely to succeed on the merits. Permanent injunctions are issued after trial, and different federal and state courts sometimes have slightly different requirements for obtaining them. The Supreme Court enumerated the traditional four-factor test in eBay Inc. v. MercExchange, L.L.C., requiring that the plaintiff has suffered irreparable injury, remedies available at law are inadequate to compensate that injury, considering the balance of hardships between the plaintiff and defendant a remedy in equity is warranted, and the public interest would not be disserved by an injunction.
Gag Orders and the Shadow of Trafigura
In England and Wales, a specific type of injunction emerged that has sparked intense debate regarding the freedom of the press and the transparency of the legal system. These are known as super-injunctions, injunctions whose existence and details may not be legally reported, in addition to facts or allegations which may not be disclosed. An example was the super-injunction raised in September 2009 by Carter-Ruck solicitors on behalf of oil trader Trafigura, prohibiting the reporting of an internal Trafigura report into the 2006 Ivory Coast toxic waste dump scandal. The existence of the super-injunction was revealed only when it was referred to in a parliamentary question that was subsequently circulated on the Internet, as parliamentary privilege protects statements by MPs in Parliament which would otherwise be held to be in contempt of court. Before it could be challenged in court, the injunction was varied to permit reporting of the question. Roy Greenslade credits the former editor of The Guardian, Alan Rusbridger, with coining the word super-injunction in an article about the Trafigura affair in September 2009. The term hyper-injunction has also been used to describe an injunction similar to a super-injunction but also including an order that the injunction must not be discussed with members of Parliament, journalists, or lawyers. One known hyper-injunction was obtained at the High Court in 2006, preventing its subject from saying that paint used in water tanks on passenger ships can break down and release potentially toxic chemicals.
Patents and the Hold-Up Problem
The intersection of intellectual property and antitrust law has created a complex arena where injunctions play a pivotal role in determining market competition. The Department of Justice and the Federal Trade Commission have investigated patent holders in the United States for seeking preliminary injunctions against accused infringers of standard-essential patents, or patents that the patent holder must license on reasonable and non-discriminatory terms. There is an ongoing debate among legal and economic scholars with major implications for antitrust policy in the United States as well as in other countries over the statutory limits to the patent holder's right to seek and obtain injunctive relief against infringers of standard-essential patents. Some scholars argue that the holder of a standard-essential patent should face antitrust liability when seeking an injunction against an implementer of a standard, citing concerns of the absence of competition facing the patent holder once its technology is locked-in to the standard. Other scholars assert that patent holders are not contractually restrained from pursuing injunctions for standard-essential patent claims and that patent law is already capable of determining whether an injunction against an infringer of standard-essential patents will impose a net cost on consumers, thus obviating the role of antitrust enforcement.
Global Variations and Modern Enforcement
Across the globe, the application of injunctions varies significantly, adapting to local legal traditions and societal needs. In the state of New South Wales, Australia, a court may grant an apprehended violence order to a person who fears violence, harassment, abuse, or stalking. The order prohibits the defendant from assaulting, harassing, threatening, stalking, or intimidating the person seeking the order, and non-compliance may result in the imposition of a fine, imprisonment, or both, and deportation. In Turkey, interim injunctions are a provisional form of injunctive relief that is an extraordinary remedy that is never awarded as of right. In each case, courts balance the competing claims of injury and consider the likely hardship on the defendant. A plaintiff seeking an interim injunction must establish that he is likely to succeed on the merits, that he is likely to suffer severe harm in the absence of preliminary relief, and that an injunction is in the public interest. In the European Union, dynamic injunctions are defined as injunctions which can be issued in cases in which materially the same website becomes available immediately after issuing the injunction with a different IP address or URL, and which is drafted in a way that allows to also cover the new IP address or URL without the need for a new judicial procedure to obtain a new injunction. Live blocking injunctions allow the repeated blocking of a website every time a live broadcast is in progress, generally used during live sporting events.
The 2025 Deportation Controversy
In 2025, the legal landscape of injunctions faced a new and controversial test when United States Attorney General Pam Bondi and other Justice Department officials argued in a court filing that an oral directive is not enforceable as an injunction. This argument arose after the second Trump administration completed deportation flights despite a federal judge verbally ordering the flights to be returned to the United States. This incident highlighted the tension between the traditional understanding of injunctions as written court orders and the practical realities of modern administrative enforcement. The scope of federal injunctive relief remains constrained by the limits on equitable remedies that existed in the English Court of Chancery around 1789, as stated by the Supreme Court in Grupo Mexicano de Desarrollo, S.A. v. Alliance Bond Fund, Inc. in 1999. Yet, as the 2025 case demonstrated, the definition and enforceability of these orders continue to evolve, challenging the boundaries between verbal commands and legally binding mandates. The case underscores the enduring power of injunctions to halt government action, even when that action is executed in the face of a verbal order from a federal judge.
