Distinguish between temporary, perpetual and mandatory injunctions. Under what circumstances can injunction be refused?

The Three Forms of Injunction

Temporary Injunctions

A temporary injunction, dealt with under section 37(1) and governed in its procedural mechanics by Order 39 of the Code of Civil Procedure, 1908, is an injunction that operates for a fixed period or until the disposal of the suit. Its purpose is essentially preservatory — to maintain the status quo between the parties while the litigation is pending, so that neither party may take advantage of the slow progress of a civil court to render the final decree infructuous.

The test for granting a temporary injunction was classically settled in American Cyanamid Co. v. Ethicon Ltd. (1975 AC 396), a formulation adopted and entrenched in Indian jurisprudence: the plaintiff must demonstrate (i) a prima facie case — not a conclusive case, but one worthy of serious investigation; (ii) that the balance of convenience lies in his favour, meaning greater hardship would flow from refusing than from granting the injunction; and (iii) that the injury would be irreparable — that is, incapable of adequate compensation in money — if the injunction is not granted. In India, the Supreme Court in Dalpat Kumar v. Prahlad Singh (AIR 1993 SC 276) adopted this three-fold test as the governing standard, and it has since been consistently applied across all courts.

Perpetual Injunctions

A perpetual injunction, governed by sections 38 to 42, is the final and conclusive relief that the court grants at the end of the trial upon a full examination of the merits. Unlike the temporary injunction, it does not merely preserve a position pending trial — it finally determines the rights of the parties with respect to the act in question. Section 38(1) states the general principle that a perpetual injunction may be granted to a plaintiff to prevent the breach of an obligation existing in his favour, whether express or implied. A perpetual injunction operates in perpetuity — it continues forever unless set aside by an appellate court or dissolved by a subsequent order.

Section 38(2) further provides that when such obligation arises from a contract, the court in granting or refusing an injunction shall be guided by the rules and provisions in Chapter II relating to specific performance. This is a consequential provision of some significance: it means that the principles governing whether a contract can be specifically enforced — relating to adequacy of compensation, fairness and hardship, conduct of the plaintiff — are equally relevant to the grant of a perpetual injunction arising out of contract.

Mandatory Injunctions

A mandatory injunction, provided for under section 39, is the most exceptional of the three. While both the temporary and perpetual injunctions in their ordinary form are prohibitory — commanding the defendant to refrain from doing something — a mandatory injunction commands the defendant to perform a positive act, typically to restore the state of affairs that existed before the defendant's wrongful interference. In the vivid illustration carried over from the old Act of 1877: A builds a house with eaves projecting over B's land. The court may issue a mandatory injunction directing A to pull down so much of the eaves as project.

The House of Lords articulated in Redland Bricks Ltd. v. Morris (1970 AC 652) — and Indian courts have thoroughly absorbed — that a mandatory injunction demands a materially higher threshold than a prohibitory one. The Supreme Court, in Dorab Cawasji Warden v. Coomi Sorab Warden (AIR 1990 SC 867), held that for an interlocutory mandatory injunction, the plaintiff must make out a strong case for trial, not merely an arguable one. The court in Mohammed Mehtab Khan v. Khushnuma Ibrahim Khan (AIR 2013 SC 1099) further clarified that the grant of interim mandatory relief requires the highest degree of satisfaction — it is, in the Supreme Court's own words, a rare and exceptional power.

A Comparative Overview

The three injunctions can be broadly distinguished along the following axes:

When Injunction Must Be Refused: Section 41

Section 41 occupies a position of great strategic importance. It specifies the circumstances in which an injunction — temporary or perpetual — cannot be granted. The section lists ten grounds, now supplemented by one more clause inserted by the 2018 Amendment. The Supreme Court in Cotton Corp of India Ltd. v. United Industrial Bank Ltd. (AIR 1983 SC 1272) held that although section 41 is cast in Chapter VIII relating to perpetual injunctions, its provisions also govern the grant of temporary injunctions — the logic being that if the final relief cannot be granted, the interim relief in identical terms cannot ordinarily be granted either.

The ten grounds deserve careful examination.

Clause (a) — Restraining pending judicial proceedings: An injunction cannot be granted to restrain a person from prosecuting a judicial proceeding that was already pending when the suit for injunction was filed — unless it is necessary to prevent a multiplicity of proceedings. The rationale is access to justice: every person has the right to prosecute a legal proceeding, and that right should not be barred except in the narrowest circumstances. The exception — prevention of multiplicity of suits — requires the court to be satisfied that the restrained proceedings are entirely unnecessary given the proceeding before it.

Clause (b) — Proceedings in a court not subordinate: No injunction may be granted to restrain a person from instituting or prosecuting proceedings in a court of co-ordinate or superior jurisdiction. A court can only restrain proceedings in courts subordinate to it. This was firmly settled by the Supreme Court in Cotton Corp of India Ltd. (AIR 1983 SC 1272), which held that the provision is founded on the equitable principle that access to courts of justice must remain unimpeded. An injunction restraining a party from filing a winding-up petition in a High Court — a court of co-ordinate jurisdiction — cannot therefore be granted by that court.

Clause (c) — Applications to a legislative body: No injunction can be granted to restrain anyone from applying to any legislative body. The provision rests on the principle of separation of powers and the fundamental right of citizens to petition their legislature. Courts of law cannot close the doors of Parliament or a State Legislature to a suitor.

Clause (d) — Criminal proceedings: An injunction cannot be issued to restrain the institution or prosecution of criminal proceedings. The civil court has no jurisdiction to fetter the hands of a criminal court. This was clearly stated in Re N.P. Essappa Chettiar (AIR 1942 Mad 756): a suit for injunction against criminal proceedings is not maintainable. Thus, when a plaintiff whose cheques were dishonoured filed a civil suit seeking to restrain the payee from prosecuting proceedings under section 138 of the Negotiable Instruments Act, the injunction was refused — the Delhi High Court in Atul Kumar Singh v. Jalveen Rosha (AIR 2000 Del 38) holding that the prayer was in substance a prayer to stay criminal proceedings.

Clause (e) — Breach of a non-specifically enforceable contract: An injunction cannot be granted to prevent the breach of a contract the performance of which the court would not specifically enforce. Since section 38(2) links the grant of injunction to the principles governing specific performance, it follows naturally that a contract excluded from specific enforcement — a determinable contract, a contract of personal service — cannot be propped up by an injunction. Courts have repeatedly held in cases involving franchise agreements, employment agreements, and distribution contracts that since they are terminable and not specifically enforceable, injunctions against their breach must be refused.

Clause (f) — Uncertain nuisance: An injunction will not be granted to prevent, on the ground of nuisance, an act which is not reasonably clear to constitute a nuisance. The court requires a strong probability — not a mere apprehension — that the act complained of will in fact be a nuisance. A quia timet (anticipatory) action requires proof of imminent danger and certainty of substantial damage. Uncertainty about whether the act will be injurious is a complete bar to injunctive relief on the ground of nuisance.

Clause (g) — Acquiescence in continuing breach: An injunction to prevent a continuing breach will be refused where the plaintiff has acquiesced in that breach. The doctrine of acquiescence, as explained in Duke of Leeds v. Earl of Amherst (1846 2 Ph 117), means that a party who, knowing his rights, stands by and passively encourages another to act in a manner inconsistent with those rights, forfeits the right to equitable relief. Mere delay, however, is not acquiescence — as the Nagpur High Court held in Murarilal v. Balkisan (AIR 1926 Nag 416). Acquiescence requires knowledge of the right coupled with conduct that amounts to implied consent or encouragement.

Clause (h) — Equally efficacious alternative remedy: An injunction cannot be granted when equally efficacious relief can certainly be obtained by any other usual mode of proceeding — except in cases of breach of trust. The three cumulative conditions are: the alternative remedy must be equally efficacious (capable of producing the same result intended by the plaintiff), it must be certain of being obtained, and it must be available through a usual mode of proceeding. The exception for breach of trust is important: a trustee's breach of obligation is so grave that the beneficiary is not driven to any alternative remedy — the injunction is available as of right.

Clause (h-a) — Infrastructure projects (2018 Amendment): Inserted by Act 18 of 2018, this clause provides that an injunction cannot be granted if it would impede or delay the progress or completion of any infrastructure project listed in the Schedule to the Act, or interfere with the continued provision of services related to such a project. This is a legislative policy decision recognising the public interest in timely infrastructure development. The list of infrastructure projects may be amended by the Central Government from time to time.

Clause (i) — Plaintiff's conduct: An injunction is an equitable remedy governed by the maxim he who comes to equity must come with clean hands. Where the conduct of the plaintiff or his agents has been such as to disentitle him to the court's assistance — through fraud, suppression of material facts, misrepresentation, or any other inequitable conduct — the court will refuse the injunction. The Supreme Court in Amar Singh v. Union of India (2011 7 SCC 69) declared that prayers for injunction must be governed by the principle of uberrima fides — the utmost good faith. A plaintiff who builds an overbridge without municipal permission cannot come to court to restrain the municipality from demolishing it.

Clause (j) — No personal interest: Finally, an injunction is a personal remedy. It cannot be granted to a plaintiff who has no personal interest in the matter — that is, who is a nominal plaintiff or has no legally protected right that is threatened by the defendant's conduct. In Premi Ratansey Shah v. Union of India (1994 5 SCC 547), the Supreme Court refused injunction to plaintiffs whose vendors had no subsisting right in the property — the plaintiffs had derived nothing and could complain of nothing.

Beyond Section 41: Discretion of the Court

Section 41 is not an exhaustive code. As the commentators and the courts have both recognised, the jurisdiction to grant an injunction is always discretionary, and a court may decline the relief even in cases not specifically covered by section 41. Three residual grounds are well-settled: first, where the injury is so trivial that a person in conscience has no ground to complain; second, where the balance of convenience strongly favours refusal; and third, where the plaintiff has been guilty of laches — delay falling short of acquiescence but sufficient to disentitle to discretionary relief. In Krothapalli Satyanarayana v. Koganti Ramaiah (AIR 1983 SC 452), the Supreme Court refused a mandatory injunction for removal of a wall because the plaintiff had filed suit nine years after the wall was built and introduced the prayer for removal only four years later — a pattern of delay and inaction that effectively disabled him from equitable relief.
