The summary suit under Order XXXVII of the Code of Civil Procedure, 1908 is the great exception to the ordinary right to be heard. A defendant who is served with a summons for judgment does not get to file a written statement and walk into a trial as of right; he must first persuade the court to let him in. That gateway is the application for leave to defend under Order XXXVII Rule 3. Get the timeline, the affidavit and the disclosure right and you earn unconditional leave; miss the ten-day window or file a vague denial and judgment is signed against you. This chapter walks through the procedure step by step, the leading authorities from Santosh Kumar to IDBI Trusteeship, and the drafting craft that decides whether your client defends on the merits or pays the decree. For the wider scheme see the Bail & Misc Order Drafting hub.
The Summary Suit: Why Leave to Defend Exists at All
Order XXXVII of the Code of Civil Procedure, 1908 creates a fast-track procedure for a defined class of money claims where the defendant, on the face of the documents, has no real answer. The object, as the Supreme Court repeatedly explains, is to prevent a defendant with no genuine defence from prolonging litigation and depriving the plaintiff of a decree he plainly deserves. The price of that speed is a deliberate inversion of the ordinary civil process: in an ordinary suit the defendant files a written statement and contests as of right, but in a summary suit the defendant has no right to defend unless and until the court grants him leave.
Rule 1(2), as substituted by the Code of Civil Procedure (Amendment) Act, 1976, confines the procedure to suits upon bills of exchange, hundies and promissory notes, and to suits in which the plaintiff seeks only to recover a debt or liquidated demand in money payable by the defendant, with or without interest, arising on a written contract, on an enactment where the sum sought is a fixed sum of money or a debt other than a penalty, or on a guarantee where the claim against the principal is in respect of a debt or liquidated demand only. Suits for unliquidated damages, accounts or specific performance fall outside Order XXXVII entirely. Understanding this gatekeeping logic is the first step before any leave-to-defend application is drafted. The procedural mindset overlaps heavily with the discipline required in other reasoned orders, surveyed in our introduction to bail and miscellaneous order drafting.
The Scheme of Order XXXVII: Rules 1 to 7 at a Glance
The procedure is best read as a sequence. Rule 1 identifies the courts and the classes of suit to which Order XXXVII applies. Rule 2 tells the plaintiff how to institute the suit: the plaint must contain a specific averment that the suit is filed under Order XXXVII, that no relief outside its scope is claimed, and the summons must be in Form No. 4 of Appendix B. Rule 3, the heart of the order, governs the defendant's appearance, the plaintiff's summons for judgment, and the application for leave to defend. Rule 4 empowers the court, under special circumstances, to set aside an ex parte decree and to give leave to appear and defend. Rules 5, 6 and 7 deal with power to order a bill or note to be deposited, recovery of interest and costs, and the residual application of the ordinary procedure of the Code respectively.
The architecture matters because the leave-to-defend application sits at a precise procedural moment: after the defendant has entered appearance and after the plaintiff has taken out a summons for judgment, but before any written statement or trial. A defendant who treats it as a routine written statement misunderstands the order. The reasoned structure expected of the resulting order mirrors what we set out in bail order structure and components.
Step One: Entering Appearance Within Ten Days
Under Order XXXVII Rule 3(1), the defendant on whom the summons in Form No. 4 is served must, within ten days of service, enter an appearance either in person or by pleader and, on doing so, file in court an address for service of notices. Rule 3(2) requires that, unless otherwise ordered, all summonses, notices and other judicial processes are thereafter served at the address so filed.
Entering appearance is not the same as obtaining leave to defend; it is merely the act that keeps the defendant in the contest. The consequence of failing to enter appearance is severe. Under Rule 2(3), if the defendant does not appear, the allegations in the plaint are deemed to be admitted and the plaintiff becomes entitled to a decree for the sum claimed, with interest and costs. The ten-day clock therefore runs from the date of service of the summons and is the first hard deadline a defence lawyer must diarise. A defendant who lets it lapse is relegated to the narrow remedy of Rule 4, discussed below.
Step Two: The Plaintiff's Summons for Judgment
Once the defendant has entered appearance, the plaintiff under Rule 3(4) takes out a summons for judgment in Form No. 4A in Appendix B, supported by an affidavit verifying the cause of action and the amount claimed and stating that in the deponent's belief there is no defence to the suit. The summons for judgment is returnable not less than ten days from the date of its service on the defendant.
This is the trigger for the defendant's right to apply for leave. The structure is deliberate: the plaintiff must first formally assert, on affidavit, that there is no defence, and only then does the burden shift to the defendant to show that there is. A summons for judgment cannot be taken out until appearance is entered, and a defendant who has not appeared cannot be heard to complain that no summons for judgment was served on him. The careful sequencing of notice and opportunity here echoes the audi alteram partem concerns that run through all order-drafting, including anticipatory bail orders.
Step Three: The Application for Leave to Defend
Rule 3(5) is the operative provision. Within ten days from the service of the summons for judgment, the defendant may, by affidavit or otherwise, disclose such facts as may be deemed sufficient to entitle him to defend, and apply on such summons for leave to defend the suit. Leave may be granted unconditionally or upon such terms as to payment into court, giving of security, framing and recording of issues or otherwise as the court or judge thinks fit.
Two limbs of the proviso to Rule 3(5) are decisive. First, leave to defend shall not be refused unless the court is satisfied that the facts disclosed by the defendant do not indicate that he has a substantial defence to raise, or that the defence intended to be put up is frivolous or vexatious. Second, where a part of the amount claimed by the plaintiff is admitted by the defendant to be due, leave to defend shall not be granted unless the amount so admitted is deposited by the defendant in court. The application is therefore won or lost on the quality of the disclosure in the affidavit, not on the eloquence of oral argument.
Rule 3(6) then provides the consequences. Where leave to defend is granted, the suit proceeds in the manner of an ordinary suit, and where leave is refused, or where the defendant fails to comply with the conditions on which leave was granted, the plaintiff is entitled to judgment forthwith.
Drafting the Affidavit: What Must Be Disclosed
Because leave turns on disclosure, the affidavit accompanying the application is the single most important document the defendant files. It must set out specific, particularised facts that, if proved, would constitute a defence. Bald denials, vague assertions of fraud without particulars, or statements that the defendant "reserves the right to take all defences" achieve nothing and routinely attract refusal of leave or, at best, heavily conditional leave.
The classic guidance is that the defendant must condescend upon particulars. If the defence is failure of consideration, the affidavit must say what was promised, what was not delivered and when. If the defence is fraud, the affidavit must plead the fraudulent representation, by whom, to whom and the manner in which it induced the transaction. If the defence is that the cheque or note was given as security and not in discharge of a debt, the surrounding facts must be deposed to. The court reads the affidavit as a self-contained statement of the proposed defence and decides, on that material alone, whether a triable issue arises. A defence lawyer drafting this affidavit is, in effect, writing the case theory in advance, much as a draftsman setting out the grounds in a reasoned order must commit to specific findings rather than generalities.
The Triable-Issue Standard: Santosh Kumar v Bhai Mool Singh
The foundational authority on the standard for granting leave is Santosh Kumar v. Bhai Mool Singh, AIR 1958 SC 321. There the plaintiff sued on a dishonoured cheque for Rs. 60,000 under the summary procedure, and the trial judge, while accepting that the defence raised a triable issue, granted leave only on condition that the defendant furnish security for the whole suit amount. The Supreme Court reversed.
The Court laid down the principle that has governed the area ever since: wherever the defence raises a triable issue, leave to defend must be given, and when that is so it must ordinarily be given unconditionally, because to fetter such leave with onerous conditions is to make the leave illusory and to deny the defendant the very trial to which the existence of a triable issue entitles him. The Court accepted that if the judge is satisfied that the defence is not bona fide, conditions may be imposed; but that conclusion cannot be reached arbitrarily, and a genuine triable issue cannot be converted into a sham merely because the judge is sceptical of its eventual success. Santosh Kumar thus draws the line between testing the genuineness of a defence and prejudging its merits, a distinction the later cases refine but never abandon.
The Mechelec Principles: Codifying When Leave Is Granted
The principles were systematised in Mechelec Engineers and Manufacturers v. Basic Equipment Corporation, AIR 1977 SC 577, (1976) 4 SCC 687. The plaintiff sued on a dishonoured cheque issued for goods said to have been supplied; the defendant admitted issuing the cheque but denied privity of contract and offered an alternative explanation. The trial court granted unconditional leave, but the Delhi High Court in revision, while conceding that triable issues arose, held the defence dishonest. The Supreme Court restored the unconditional leave.
In doing so the Court adopted the now-celebrated propositions, drawn from the Calcutta High Court's decision in Smt. Kiranmoyee Dassi v. Dr. J. Chatterjee, AIR 1949 Cal 479. In substance: (a) if the defendant satisfies the court that he has a good defence on the merits, he is entitled to unconditional leave; (b) if he raises a triable issue indicating a fair or bona fide or reasonable defence, though not a positively good defence, he is ordinarily entitled to unconditional leave; (c) if he discloses such facts as may be deemed sufficient to entitle him to defend, that is, if the affidavit discloses a fair probability of a bona fide defence, he is entitled to leave, though it may be conditional; (d) if the defence raised is illusory or sham or practically moonshine, the court may show mercy by granting leave on condition of the amount being brought into court; and (e) if the defence is illusory or sham or practically moonshine, leave may be refused altogether. The High Court's error was to treat a genuine triable issue as dishonest, which it had no proper basis to do.
Conditional Leave and the Discretion to Impose Terms
Between unconditional leave and outright refusal lies the court's discretion to grant conditional leave, exercised most often by directing the defendant to deposit the claim amount or furnish security. The leading early authority is Milkhiram (India) Pvt. Ltd. v. Chamanlal Bros., AIR 1965 SC 1698, where the Court recognised that where the defence, though disclosing a triable issue, appears doubtful in its bona fides, the court may protect the plaintiff by attaching terms to the leave.
The principle is one of calibration. Conditions are not punitive; they exist to reconcile two interests, the defendant's right to a trial where a triable issue exists, and the plaintiff's interest in not being kept out of an apparently sound claim while a doubtful defence is litigated. The condition must be proportionate to the strength of the doubt: a small deposit where the defence is weak but arguable, a fuller security where it is plausible but improbable, and no condition at all where the issue is squarely triable and bona fide. A condition so onerous that the defendant cannot meet it, imposed where a genuine triable issue exists, is an error of principle because it effectively refuses leave under the guise of granting it, exactly the vice condemned in Santosh Kumar. The structured exercise of discretion here is the same craft demanded when calibrating conditions in a bail order in non-bailable offences.
Sham Defences and the Mercy Condition: Sunil Enterprises
The treatment of weak defences was elaborated in Sunil Enterprises v. SBI Commercial and International Bank Ltd., (1998) 5 SCC 354. The bank sued on bills of exchange that the appellants had accepted; the appellants sought leave to defend, alleging that the bills were without consideration because no goods had been sold or supplied and that there was fraud and collusion between the bank's officers and a third party.
The Supreme Court restated the spectrum of defences and the corresponding orders, reaffirming the Mechelec framework. It explained that where the defendant has no defence, or where the defence is sham or illusory or practically moonshine, the defendant is not entitled to leave; but even there the court may, as an act of mercy, allow the defendant to attempt to prove his defence on condition that the claimed amount is brought into court or otherwise secured, thereby protecting the plaintiff. On the facts, the Court found that the allegations raised genuine triable issues and granted unconditional leave, setting aside the contrary order of the Division Bench. Sunil Enterprises is the bridge case: it confirms that the discretionary condition is rooted in mercy to a weak defendant, not in suspicion of a strong one.
No Rejection for Mere Implausibility: Defiance Knitting
The caution against using the leave stage to decide the suit was reinforced in Defiance Knitting Industries Pvt. Ltd. v. Jay Arts, (2006) 8 SCC 25. The respondent had filed a summary suit for recovery of a substantial sum, and the question was whether the defendant had made out a case for unconditional leave to defend.
The Supreme Court held that summary judgment ought not to be given where there is a serious conflict as to a matter of fact or where any difficulty on a question of law arises. Crucially, the Court held that a court should not reject the defendant's defence merely because of its inherent implausibility or its apparent inconsistency. The leave stage is not a mini-trial; the judge weighs whether a triable issue exists, not whether the defence will ultimately prevail. A defence that is improbable but not impossible is still a defence, and the appropriate response to doubt about its strength is a proportionate condition, not refusal. Defiance Knitting is the authority a defence lawyer cites when a trial court has effectively tried the suit at the leave stage and refused leave on a view of the merits it had no business forming.
The Modern Restatement: IDBI Trusteeship v Hubtown
The most recent authoritative restatement is IDBI Trusteeship Services Ltd. v. Hubtown Ltd., (2017) 1 SCC 568, where the Supreme Court (R.F. Nariman J.) reviewed the entire line of authority and reformulated the principles, expressly reading down the somewhat harsh language of the earlier cases. The Court set out a graded scheme:
First, if the defendant satisfies the court that he has a substantial defence, that is, a defence likely to succeed, he is entitled to unconditional leave. Second, if he raises triable issues indicating a fair or reasonable defence, although not a positively good defence, he is ordinarily entitled to unconditional leave. Third, even where triable issues are raised, if the court doubts the defendant's good faith or the genuineness of the triable issues, or if the defence is plausible but improbable, the court may grant conditional leave, ordering deposit of the amount claimed or a part of it, or furnishing of security. Fourth, if the defendant has no substantial defence or raises no genuine triable issue, and the defence is frivolous or vexatious, leave is refused and the plaintiff gets judgment. Fifth, where part of the amount claimed is admitted to be due, leave shall not be granted unless that admitted amount is deposited in court, mirroring the proviso to Rule 3(5).
On the facts, the Court found the defendant's defence to be in the realm of the plausible but improbable and accordingly granted conditional leave, directing the defendant to deposit the principal amount in court as the price of contesting. IDBI Trusteeship is now the first port of call in any leave-to-defend argument, and its fivefold restatement is the framework a judge is expected to apply expressly in the order.
The Safety Valve: Setting Aside the Decree Under Rule 4
A defendant who misses the appearance deadline or against whom judgment has been signed is not always without remedy. Rule 4 provides that after a decree, the court may, under special circumstances, set aside the decree and, if necessary, stay or set aside execution, and may give leave to the defendant to appear to the summons and to defend the suit, if it seems reasonable to the court so to do and on such terms as it thinks fit.
The threshold of "special circumstances" is higher than the "sufficient cause" standard for setting aside an ordinary ex parte decree under Order IX Rule 13. The defendant must show something more than ordinary negligence, such as illness, fraud in service, or a genuine non-receipt of the summons, and must usually demonstrate that he has a defence on the merits worth trying. Courts frequently impose terms, such as deposit of the decretal amount, when exercising this discretion, consistent with the conditional-leave philosophy that pervades the order. Rule 4 is the summary suit's narrow safety valve, not a routine second chance, and a defendant who relies on it carries a substantially heavier burden than one who applies for leave within time under Rule 3.
Practical Checklist for the Leave-to-Defend Application
For the practitioner, the procedure reduces to a disciplined sequence. Confirm the suit is properly constituted under Order XXXVII, because a suit that does not fall within Rule 1(2) cannot be summary and the leave machinery does not apply. Diarise the ten-day appearance window from service of the summons, then the ten-day window from service of the summons for judgment, treating both as non-negotiable. Draft the affidavit to disclose specific, particularised facts amounting to a defence, anchoring each to the Mechelec and IDBI Trusteeship categories so the court can place the defence on the spectrum.
If part of the claim is admitted, advise the client that the admitted sum must be deposited as a precondition to any leave, and quantify it precisely in the affidavit. Anticipate conditional leave where the defence is arguable but doubtful, and be ready to argue proportionality, citing Santosh Kumar against any condition so heavy as to be a disguised refusal. Where leave is refused or conditions are not met, judgment follows under Rule 3(6), so compliance with any condition must itself be diarised. The whole exercise rewards precision over rhetoric, the same quality that distinguishes a sound reasoned order from a vulnerable one across the order-drafting syllabus.
Frequently asked questions
What is the time limit for applying for leave to defend a summary suit?
Under Order XXXVII Rule 3(5) CPC, the defendant must apply for leave to defend within ten days from the service of the summons for judgment. Separately, under Rule 3(1), he must have entered appearance within ten days of service of the original summons. Both ten-day windows are strict, and missing the first relegates the defendant to the narrow Rule 4 remedy of setting aside the decree.
When is a defendant entitled to unconditional leave to defend?
Following Santosh Kumar v. Bhai Mool Singh (AIR 1958 SC 321) and IDBI Trusteeship Services Ltd. v. Hubtown Ltd. ((2017) 1 SCC 568), a defendant is entitled to unconditional leave where he shows a substantial defence likely to succeed, or raises a triable issue indicating a fair or reasonable defence. Where a genuine triable issue exists, imposing onerous conditions is impermissible because it makes the leave illusory.
Can a court grant conditional leave to defend, and on what basis?
Yes. Under the proviso to Rule 3(5) and as explained in Milkhiram (India) v. Chamanlal Bros. (AIR 1965 SC 1698) and IDBI Trusteeship, where the court doubts the defendant's good faith or finds the defence plausible but improbable, it may grant leave on terms such as deposit of the claim amount or furnishing of security. The condition must be proportionate to the doubt and must not be so onerous as to amount to a disguised refusal.
What must the defendant's affidavit disclose to obtain leave?
The affidavit must disclose specific, particularised facts that, if proved, would constitute a defence, not bald denials or vague reservations. The court decides on that material alone whether a triable issue arises. As Mechelec Engineers v. Basic Equipment Corporation (AIR 1977 SC 577) shows, the defence must be placed on the spectrum from good defence to sham so the court can determine whether leave should be unconditional, conditional, or refused.
What happens if part of the claimed amount is admitted?
The proviso to Order XXXVII Rule 3(5) is mandatory: where a part of the amount claimed is admitted by the defendant to be due, leave to defend shall not be granted unless that admitted amount is deposited by the defendant in court. The defendant should quantify the admitted sum precisely and be prepared to deposit it as a precondition to contesting the balance.
Can a court reject a defence simply because it seems improbable?
No. In Defiance Knitting Industries Pvt. Ltd. v. Jay Arts ((2006) 8 SCC 25), the Supreme Court held that a court should not reject the defendant's defence merely because of its inherent implausibility or apparent inconsistency. The leave stage is not a mini-trial; the proper response to doubt about a defence's strength is a proportionate condition, not outright refusal of leave.
