          Appeal from the United States District Court
               for the Northern District of Texas
                     USDC No. 3:98-CV-1669-H
                        February 13, 2001

Before GARWOOD, PARKER, and DENNIS, Circuit Judges.

PER CURIAM:*

     Roy Trujillo, Jr., filed this 42 U.S.C. § 1983 civil rights

suit against appellant Steven G. O’Brien, a Dallas police officer,


     *
      Pursuant to 5TH CIR. R. 47.5, the Court has determined that
this opinion should not be published and is not precedent except
under the limited circumstances set forth in 5TH CIR. R. 47.5.4.
and other defendants, alleging that O’Brien used excessive force

when effecting an arrest of him.             O’Brien filed a motion for

summary judgment on the basis of qualified immunity.              The district

court refused to grant that motion, and this appeal followed.

     District court orders denying summary judgment on the basis of

qualified immunity are immediately appealable under the collateral

order doctrine, notwithstanding their interlocutory character, when

based on a conclusion of law.        See Mitchell v. Forsyth, 

, 530 (1985).       Such orders are not immediately appealable,

however, if they are based on a determination that a genuine issue

of material facts exists.     See Johnson v. Jones, 

, 313

(1995).     Because the district court’s ruling was based on a

determination   that   significant    factual      issues    remained    as    to

circumstances   surrounding    O’Brien’s      shooting      and   subduing     of

Trujillo, this court does not have jurisdiction to review the

denial of O’Brien’s motion for summary judgment based on qualified

immunity.    Accordingly,     the   appeal    is   DISMISSED      FOR   LACK   OF

JURISDICTION.
