Stephen F. Austin State University (“SFA”) brings an interlocutory appeal of the district court’s order requiring SFA to appear for a deposition pursuant to Federal Rule of Civil Procedure 30(b)(6). The face of the briefing discloses that the depositions have taken place. Accordingly, the challenge to those depositions is moot. SFA argues that its appeal is not moot because the depositions may be used at trial, now scheduled for July of 2013, and it may be ordered to testify at trial. 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. Amar v. Whitley, 100 F.3d 22, 24 (5th Cir. 1996) (federal courts lack jurisdiction to issue advisory opinions and possibility of future issue does not warrant exception to mootness dismissal). We conclude that we lack jurisdiction over this appeal and DISMISS the appeal for want of jurisdiction.
