Answers may be supplemented and objections must be stated with specificity.

Why it Matters?

The subpart counting rule is what constrains their use, since a question with multiple discrete components counts as several against the limit. Drafting to maximize information within the limit means using interrogatories for compilation tasks such as identifying witnesses, computing damages, and stating the factual basis for contentions, rather than for narrative that will be answered by counsel.
