An injunction is a judicial order issued by a court of equity, either restraining a person from doing a specified act (prohibitory) or compelling them to do a specified act (mandatory). In India, the law relating to injunctions is primarily governed by the Specific Relief Act, 1963 (Sections 36-42) and the Code of Civil Procedure, 1908 (Order 39).

Various Kinds of Injunctions:

1. Temporary (Interlocutory) Injunctions:

   • Nature: These are provisional orders granted during the pendency of a suit to maintain the status quo until the final determination of the rights of the parties. They are temporary in nature, lasting for a specified period or until further orders of the court.
   • Governed by: Order 39, Rules 1 and 2 of the Code of Civil Procedure, 1908.
   • Grounds for Granting (The 'Triple Test'): Courts typically consider three essential conditions before granting a temporary injunction:
     • Prima Facie Case: The applicant must demonstrate a strong likelihood of success on the merits of the case. This means there is a serious question to be tried, and the applicant has a fair chance of obtaining the relief sought.
     • Irreparable Injury: The applicant must show that they will suffer irreparable harm or injury if the injunction is not granted, and such harm cannot be adequately compensated by monetary damages. The injury must be substantial and not easily quantifiable.
     • Balance of Convenience: The court must weigh the inconvenience or injury that would be caused to the applicant if the injunction is refused against the inconvenience or injury that would be caused to the respondent if the injunction is granted. The balance must tilt significantly in favor of the applicant.

2. Perpetual (Permanent) Injunctions:

   • Nature: These are granted after a full hearing on the merits of the case, finally settling the rights of the parties. A perpetual injunction permanently restrains the defendant from asserting a right or committing an act contrary to the plaintiff's rights.
   • Governed by: Sections 38-42 of the Specific Relief Act, 1963.
   • Grounds for Granting (Section 38 SRA): A perpetual injunction may be granted to the plaintiff to prevent the breach of an obligation existing in their favor, whether expressly or by implication. Specifically, when the defendant invades or threatens to invade the plaintiff's right to, or enjoyment of, property, and:
     • The defendant is a trustee of the property for the plaintiff.
     • There exists no standard for ascertaining the actual damage caused, or likely to be caused, by the invasion.
     • The invasion is such that pecuniary compensation would not afford adequate relief.
     • It is probable that pecuniary compensation cannot be obtained for the invasion.
     • The injunction is necessary to prevent a multiplicity of judicial proceedings.

3. Mandatory Injunctions:

   • Nature: Unlike prohibitory injunctions, which prevent an act, a mandatory injunction compels the performance of an act. It directs the defendant to do something to prevent the breach of an obligation.
   • Governed by: Section 39 of the Specific Relief Act, 1963.
   • Grounds for Granting: When, to prevent the breach of an obligation, it is necessary to compel the performance of certain acts which the court is capable of enforcing, the court may grant a mandatory injunction. These are typically granted in cases where a wrong has already been committed, and the court orders the defendant to undo the wrong or restore the previous state.

General Principles and Discretionary Nature: It is crucial to remember that injunctions are discretionary remedies. The court is not bound to grant an injunction merely because it is lawful to do so. The court exercises its discretion based on various factors, including the conduct of the parties, any delay or acquiescence by the applicant, and the principle that 'he who seeks equity must come with clean hands.' Section 41 of the Specific Relief Act also lists specific instances where injunctions cannot be granted (e.g., to restrain a person from prosecuting a judicial proceeding, to prevent a breach of contract the performance of which would not be specifically enforced).
