concurring.
I agree that the Court of Appeals was wrong in holding that the moving defendant must always support his motion with evidence or affidavits showing the absence of a genuine dispute about a material fact. I also agree that the movant may rely on depositions, answers to interrogatories, and the like, to demonstrate that the plaintiff has no evidence to prove his case and hence that there can be no factual dispute. But the movant must discharge the burden the Rules place upon him: It is not enough to move for summary judgment without supporting the motion in any way or with a con-clusory assertion that the plaintiff has no evidence to prove his case.
A plaintiff need not initiate any discovery or reveal his witnesses or evidence unless required to do so under the discovery Rules or by court order. Of course, he must respond if required to do so; but he need not also depose his witnesses or obtain their affidavits to defeat a summary judgment motion asserting only that he has failed to produce any support for his case. It is the defendant’s task to negate, if he can, the claimed basis for the suit.
Petitioner Celotex does not dispute that if respondent has named a witness to support her claim, summary judgment should not be granted without Celotex somehow showing that the named witness’ possible testimony raises no genuine issue of material fact. Tr. of Oral Arg. 43, 45. It asserts, however, that respondent has failed on request to produce any basis for her case. Respondent, on the other hand, does not contend that she was not obligated to reveal her witnesses and evidence but insists that she has revealed enough to defeat the motion for summary judgment. Because the Court of Appeals found it unnecessary to address this aspect *329of the case, I agree that the case should be remanded for further proceedings.
