Commissions, Interrogatories and Discovery in Civil Suits

How the CPC lets a civil court gather facts before trial: interrogatories and discovery under Order XI, and commissions under Section 75 and Order XXVI, with leading cases.

Interrogatories, discovery and commissions are tools in the Code of Civil Procedure, 1908 (CPC) that help a civil court collect facts before and during trial. Interrogatories and discovery of documents are governed by Section 30 and Order XI, and they let one party extract written answers and documents from the other. Commissions are governed by Section 75 and Order XXVI, and they let the court send a commissioner to record evidence, inspect property, examine accounts, divide land or carry out other tasks the court cannot conveniently do itself.

This explainer is written for B.A. LL.B. and LL.B. students preparing for Civil Procedure papers, and for citizens who have a property or money dispute and want to understand what their advocate is asking the court for. Knowing these tools saves time: a well framed interrogatory or a timely local commission can settle a factual question that would otherwise take months of oral evidence.

What does the CPC actually say?

The power begins in the body of the Code. Section 30 allows the court, at any time, on its own motion or on a party's application, to make orders about the delivery and answering of interrogatories, the admission, discovery, inspection and production of documents, to summon persons to give evidence or produce documents, and to order any fact to be proved by affidavit.

Section 75 lists the purposes for which a court may issue a commission:

  • to examine any person;
  • to make a local investigation;
  • to examine or adjust accounts;
  • to make a partition;
  • to hold a scientific, technical or expert investigation;
  • to conduct sale of property that is subject to speedy and natural decay and is in court custody during the suit;
  • to perform any ministerial act.

The detailed procedure sits in the First Schedule: Order XI for discovery and inspection, and Order XXVI for commissions.

How do interrogatories work under Order XI?

An interrogatory is a written question that one party serves on the other, which must be answered on oath. Picture a homeowner in Nagercoil who sues a contractor over a defective house. Instead of waiting for cross-examination, the plaintiff can ask in writing whether the contractor bought cement from a named supplier, and on which dates.

  1. Leave of court is required. Rule 1 allows either party to deliver interrogatories only with the court's leave.
  2. The questions go to the court first. Under Rule 2 the proposed interrogatories are filed with the application, and the court is to decide the application within seven days of filing.
  3. Form. Rule 4 prescribes Form No. 2 in Appendix C.
  4. Objections. Rule 7 lets the other side apply to set aside interrogatories within seven days of service.
  5. Answer by affidavit. Rule 8 requires answers by affidavit within ten days, or such other time as the court allows.
  6. Costs. Under Rule 3, interrogatories found unreasonable, vexatious or of improper length are paid for by the party at fault.

What are discovery, inspection and production of documents?

Discovery forces the other side to disclose, on affidavit, the documents in its possession or power that relate to the matters in question. Under Rule 12 a party may apply without filing an affidavit, but the court will not order discovery where it thinks it is unnecessary. Rule 14 lets the court order production of documents at any stage of the suit. Rule 15 entitles a party, by notice given at or before the settlement of issues, to inspect documents referred to in the other side's pleadings or affidavits, and a party who refuses that notice cannot later put the document in evidence.

The teeth are in Rule 21. A plaintiff who fails to comply with an order to answer interrogatories or for discovery or inspection may have the suit dismissed for want of prosecution, and is then barred from bringing a fresh suit on the same cause of action. A defaulting defendant may have the defence struck out.

For commercial suits, Order XI has been substituted with a stricter disclosure regime under the Commercial Courts Act, 2015. Students should check that version separately before writing about commercial disputes.

How has the Supreme Court read these provisions?

  • M.L. Sethi v. R.P. Kapur (1972): decided on 19 July 1972 (AIR 1972 SC 2379). The Court held that a document need not be admissible to be discoverable. It is enough if it throws light on the matter in controversy, including documents that may lead to a line of enquiry which either advances the applicant's case or damages the opponent's. The Court also held that discovery under Order XI Rule 12 is available in an application to sue as a pauper under Order XXXIII, where bank and property records were relevant to the applicant's means.
  • Salem Advocate Bar Association, Tamil Nadu v. Union of India (2005): decided on 2 August 2005 (AIR 2005 SC 3353). The Court explained the power to have evidence recorded by a commissioner under Order XVIII Rule 4 and Order XXVI Rule 4A, and said the discretion to send cross-examination to a commissioner must be used with great circumspection, especially in complex matters such as title disputes or disputed wills.
  • Haryana Waqf Board v. Shanti Sarup (2008): decided on 16 July 2008. Where the real dispute was the demarcation of the suit land, the Court held that the application for demarcation through a local commissioner under Order XXVI Rule 9 was wrongly rejected. It set aside the High Court's summary dismissal and restored the second appeal for a decision on merits.

When will a court issue a commission?

Order XXVI covers several situations. Rule 1 allows a commission to examine a witness who is exempt from attending or unable to attend because of sickness or infirmity. Rule 4 covers witnesses living outside the court's local limits, and Rule 4A lets any court issue a commission for a resident within its jurisdiction in the interest of justice or for speedy disposal. Rule 9 is the familiar local commission: a tenant in Madurai disputing whether a landlord's new wall encroaches on a common passage might ask for an advocate commissioner to visit, measure and report. Rule 10A covers scientific investigation, Rule 11 accounts, and Rule 13 partition after a preliminary decree.

Under Rule 10(2), the commissioner's report and the evidence recorded by him are evidence in the suit, but the evidence cannot be read without the report. The court or a party, with leave, may examine the commissioner in open court. Rule 15 requires the party seeking the commission to deposit expenses within the time the court fixes, and Rule 18B requires the court to fix a date for return, which can be extended only for sufficient cause recorded in writing.

Where does the Bharatiya Sakshya Adhiniyam come in?

The Indian Evidence Act, 1872 has been replaced by the Bharatiya Sakshya Adhiniyam, 2023 (BSA) from 1 July 2024. For production of documents, cite Section 165 BSA: a witness summoned to produce a document must bring it to court despite any objection, and the court decides the validity of the objection. The CPC orders discussed above are unchanged by the BSA.

How should you write this in an exam?

  1. Open with the purpose: narrowing issues, saving time, preventing surprise at trial.
  2. Cite the source of power (Section 30 or Section 75) and then the relevant Order and rules.
  3. Give the procedure in steps with time limits (seven days, ten days).
  4. Add consequences (Rule 21) and one leading case for each topic.
  5. Finish with a short practical illustration from a land or money suit.

Frequently asked questions

Q1Can I serve interrogatories without the court's permission?

No. Order XI Rule 1 requires leave of the court, and Rule 2 requires the proposed questions to be submitted with the application.

Q2How long does the other side have to answer interrogatories?

Under Order XI Rule 8, answers are given by affidavit within ten days, or within any other time the court allows.

Q3Is a local commissioner's report binding on the court?

It is evidence in the suit under Order XXVI Rule 10(2), not a final finding. The court can examine the commissioner and, if not satisfied, order a further inquiry.

Q4What happens if a plaintiff ignores a discovery order?

Under Order XI Rule 21, the suit may be dismissed for want of prosecution, and the plaintiff is barred from filing a fresh suit on the same cause of action.
