Rule 1.
Discovery by interrogatories
In any suit the plaintiff or defendant by leave of the Court may deliver interrogatories in writing for the examination of the opposite parties or any one or more of such parties, and such interrogatories when delivered shall have a note at the foot thereof stating which of such interrogatories each of such persons is required to answer:
Provided that no party shall deliver more than one set of interrogatories to the same party without an order for that purpose:
Provided also that interrogatories which do not relate to any matters in question in the suit shall be deemed irrelevant, notwithstanding that they might be admissible on the oral cross-examination of a witness.
Rule 8.
Affidavit in answer, filing
Interrogatories shall be answered by affidavit to be filed within ten days, or within such other time as the Court may allow.
Rule 12.
Application for discovery of documents
Any party may, without filing any affidavit, apply to the Court for an order directing any other party to any suit to make discovery on oath of the documents which are or have been in his possession or power, relating to any matter in question therein. On the hearing of such application the Court may either refuse or adjourn the same, if satisfied that such discovery is not necessary, or not necessary at that stage of the suit, or make such order, either generally or limited to certain classes of documents, as may, in its discretion, be thought fit.
Rule 14.
Production of documents
It shall be lawful for the Court, at any time during the pendency of any suit, to order the production by any party thereto, upon oath, of such of the documents in his possession or power, relating to any matter in question in such suit, as the Court shall think right; and the Court may deal with such documents, when produced, in such manner as shall appear just.
Rule 21.
Non-compliance with order for discovery
(1)Where any party fails to comply with any order to answer interrogatories, or for discovery or inspection of documents, he shall, if a plaintiff, be liable to have his suit dismissed for want of prosecution, and, if a defendant, to have his defence, if any, struck out, and to be placed in the same position as if he had not defended, and the party interrogating or seeking discovery or inspection may apply to the Court for an order to that effect, and an order may be made on such application accordingly, after notice to the parties and after giving them a reasonable opportunity of being heard.
Legal Commentary & Landmark Judgments: Order 11
Order XI provides the procedural framework for discovery and inspection, authorizing parties to deliver interrogatories, demand discovery of documents on oath, and inspect adversary records prior to trial.
When a defendant suppresses original contracts or accounts, move an application for Discovery on Oath under Order 11 Rule 12; failure to file the affidavit of documents within the ordered period entitles you to apply to strike out their defense under Rule 21.
