Order XI Rule 3 CPC: Costs of Interrogatories Explained

Order XI Rule 3 of the Code of Civil Procedure, 1908 regulates the costs caused by interrogatories that are unreasonable, vexatious or unnecessarily lengthy. It protects parties from bearing expenses caused by improper use of written questions in civil litigation.

Indian civil procedure | Updated 13 October 2026
Key takeaway: Where interrogatories have been used unreasonably, vexatiously or at improper length, the court or taxing officer may require the party at fault to pay the costs caused by the interrogatories and the answers, regardless of the usual outcome on costs.

What does Order XI Rule 3 CPC provide?

Statutory rule - costs of interrogatories (substance)

When adjusting the costs of a suit, an inquiry into the propriety of interrogatories must be made at a party's instance. If the taxing officer or the court, with or without an application for inquiry, considers that interrogatories were exhibited unreasonably, vexatiously or at improper length, the costs occasioned by the interrogatories and their answers must be borne by the party at fault, in any event.

An interrogatory is a formal written question delivered by one litigating party to an opposing party as a discovery procedure, ordinarily subject to the court's permission under Order XI Rule 1 CPC. The phrase costs occasioned refers to expenses attributable to preparing, delivering, dealing with and answering the improper interrogatories, as assessed under the applicable procedure.

Rule 3 is concerned with the financial consequences of misuse of discovery. It is distinct from the court's power to refuse leave for interrogatories or strike out objectionable questions.

When can costs of interrogatories be imposed?

  • Unreasonable interrogatories: questions that are unnecessary or disproportionate to the matters genuinely in dispute.
  • Vexatious interrogatories: questions used to harass, burden or improperly pressure the opposing party rather than advance fair resolution.
  • Interrogatories at improper length: an excessive number or unnecessarily elaborate questions generating avoidable expense.

These are statutory grounds. A court considers the relevance, necessity, scope and actual circumstances of the questioning; merely losing an application or asking a difficult question does not by itself establish improper conduct.

How are costs assessed under Rule 3?

  1. Identify the interrogatories: the court considers the particular written questions and the circumstances in which they were delivered.
  2. Examine propriety: a party may request an inquiry when costs are adjusted; the court or taxing officer may also consider the matter as the rule permits.
  3. Determine the fault: the decision-maker assesses whether the questions were unreasonable, vexatious or improperly lengthy.
  4. Allocate attributable expenses: the costs caused by the interrogatories and answers are charged to the party at fault, even if that party would otherwise have been entitled to costs in the suit.

For example, if a party serves repetitive questions unrelated to the issues and the opponent incurs expense preparing answers, the court may consider whether those expenses should be borne by the party responsible for the improper interrogatories. The result depends on the record and the applicable costs rules.

Relationship with other CPC rules and commercial litigation

Order XI Rule 2 concerns submission of proposed interrogatories and the court's assessment of their necessity. Order XI Rule 7 deals with setting aside or striking out improper interrogatories. Order XI Rule 8 governs answering by affidavit.

Important distinction: The Commercial Courts Act, 2015 introduced a substituted Order XI for commercial disputes of specified value. In that framework, Rule 3 concerns inspection, not the ordinary CPC Rule 3 on costs of interrogatories. This article addresses the ordinary Order XI Rule 3 and should not be applied automatically to commercial suits governed by the substituted procedure.

Frequently asked questions

Who can request an inquiry into improper interrogatories?

Any party may seek an inquiry into the propriety of interrogatories when costs of the suit are being adjusted. The rule also recognises consideration by the court or taxing officer without a separate application for inquiry.

Does Rule 3 impose costs automatically for every interrogatory?

No. The statutory consequence arises where the court or taxing officer finds the interrogatories unreasonable, vexatious or at improper length.

Can the party who ultimately wins the suit still pay these costs?

Yes. The words "in any event" indicate that the party at fault may be made to bear the expenses caused by improper interrogatories independently of the ordinary allocation of litigation costs.

Is Order XI Rule 3 the same in commercial suits?

No. The substituted Order XI applicable to specified commercial disputes has different rule numbering and subject matter. The procedural regime must be identified before relying on a particular rule.

Conclusion

Order XI Rule 3 CPC discourages misuse of interrogatories by assigning avoidable discovery expenses to the party responsible. Written questions should be focused, relevant and proportionate to the issues in dispute.
