This is an application to file, in forma pauperis, a Petition for Writ of Mandamus, to require Respondent to entertain a motion seeking a medical examination and to conduct a hearing thereon, to determine the mental competency of Petitioner, pursuant to 18 U.S.C. § 4245.

From an examination of the records of the United States District Court Clerk, Western District of Oklahoma, it appears that there has been no certification from the Director of the Bureau of Prisons that Petitioner “ * * * has been examined by the board of examiners * * * ” and that “ * * * there is probable cause to believe that such person was incompetent at the time of his trial.” See: *224 18 U.S.C. § 4245. In the absence of such -certification, Respondent lacked jurisdiction to conduct the hearing sought. See: United States v. Thomas, 6 Cir, 291 F.2d 478.

Leave to proceed in forma pauperis is .accordingly denied and the case is dismissed.
