Oh, Federal court. OK, it's the same but different. :) The plaintiff schedules a discovery conference where the two parties develop a discovery plan and present it to the court. During that conference it is agreed what will be discovered. There is a time constraint.
It's still discovery, just organized by conference rather than the civil version where you usually just request all appertaining docs, names of witnesses, subpoena for depositions etc. outside of a conference and a formal plan.
You still have to go through the motions. You may have something if they've waited too long, but then the judge will probably just give them more time.
