Full Text of Rule 4007.3

Text size

Unless the court upon motion, for the convenience of parties and witnesses and in the interests of justice, orders otherwise, methods of discovery may be used in any sequence and the fact that a party is conducting discovery, whether by depo- sition or otherwise, shall not operate to delay any other party’s discovery.

Plain-English Summary

This rule frees discovery from a fixed order. Unless the court, on motion and for the convenience of parties and witnesses and in the interest of justice, directs otherwise, the several methods of discovery — depositions, interrogatories, production, and the rest — may be used in any sequence.

One party’s use of discovery does not delay another party’s, so both sides can proceed at once. Letting discovery run in parallel and in any order avoids the gamesmanship and delay that a rigid sequence would invite.

Frequently Asked Questions

Must discovery be taken in a set order?

No. The methods may be used in any sequence unless the court orders otherwise.

Can both sides take discovery at the same time?

Yes. One party's discovery does not delay another party's.

Official Note

Explanatory Note Neither the Federal Rules, prior to their amendment in 1970, nor prior Rule 4007 dealt with this subject. Some courts held that a party who first gave notice obtained a priority which would prevent depositions or discovery by other parties until the first party had completed his own depositions and discovery. This led to a ‘‘race to the courthouse.’’ The proposed Rule, which is taken almost verbatim from Fed. R.Civ.P. 26(d), is designed to reverse these decisions. In principle, a party first initiating discovery gets no priority whatever. Nothing prevents other par- ties from proceeding simultaneously with their discovery. Further, all methods of discovery may be used in any sequence; for example, interrogatories may precede oral depositions, or oral depositions may be followed by interrogatories or requests for admissions or requests for production of documents. All this, however, is subject to the control of the court, which may enter special orders ‘‘for the convenience of parties and witnesses and in the interest of justice.’’
