Full Text of Rule 30.3
Plain-English Summary
Rule 30.3 gives defense counsel a tool for tracking down the state’s witnesses before trial. On request, the district attorney has to hand over the addresses and phone numbers of the state’s witnesses, to the extent the district attorney knows them, and the information is shared with defense counsel in confidence, as an officer of the court.
The rule builds in one exception. If the judge finds good cause, the court can excuse the district attorney from that disclosure requirement. But that exception comes with its own trade-off: defense counsel still has to get a chance to interview the withheld witnesses before they testify at trial.
