Timing matters.

In Cutler v. Stephen F. Austin State University, the defendant sought interlocutory review of an order requiring it to appear for a deposition under Fed. R. Civ. P. 30(b)(6).  No. 12-41393.  The Fifth Circuit found the appeal moot because the depositions had already taken place.  The defendant argued that the appeal was not moot because the depositions may be used at an upcoming trial.  The Court responded: “This court does not have jurisdiction to issue advisory opinions regarding decisions of the district court that have not been made at a trial that has not been held.”
