Which rule governs interrogatories?

• A. Rule 34
• B. Rule 33
• C. Rule 26
• D. Rule 36

Answer: (B)

Interrogatories are a written discovery tool used to obtain information from the other party, to be answered under oath. The rule that governs this tool is Rule 33. It authorizes serving interrogatories on another party, limits the number to 25 per party (including subparts) unless the court orders otherwise, and requires answers under oath with any objections. The typical deadline to respond is 30 days after service, though extensions can be allowed by the court or agreed by the parties. The scope and ability to object are tied to Rule 26, which sets the broader discovery framework and relevance limits. If a question is improper, a party can object or move to compel under Rule 37. Other discovery devices are covered by different rules: production of documents and things by Rule 34, and requests for admission by Rule 36. For nonparties, interrogatories aren’t used; subpoenas under Rule 45 would be the path. Thus, Rule 33 governs interrogatories.
