a. courts of equity.
Injunction is a legal remedy that was developed and is primarily granted by courts of equity. Courts of equity are a separate system of courts that originated in England to provide remedies when the common law courts were unable to offer adequate relief. Injunctions are orders issued by courts of equity to require a party to refrain from doing a certain act or to perform a specific action. They are used to prevent harm or irreparable injury, preserve the status quo, or enforce equitable rights and remedies.
Common law courts, administrative tribunals, and ombudsman offices may have their own procedures and remedies, but the granting of injunctions is closely associated with courts of equity.
