Per Curiam
ORDER
Upon consideration of the petition for writ of mandamus, it is
ORDERED that the petition for writ of mandamus be dismissed as moot. Petitioner seeks to compel the district court to file and rule on his complaint against an immigration and custom enforcement official, an official at the El Paso Intelligence Center, and others. It appears that the district court filed that complaint in No. 09cv423 on March 5, 2009, and dismissed it on the same day. To the extent petitioner seeks to challenge the district court's dismissal order, mandamus cannot be used as a substitute for appeal. See In re GTE Serv. Corp., 762 F.2d 1024, 1026-27 (D.C. Cir. 1985).
Pursuant to D.C. Circuit Rule 36, this disposition will not be published.
