UNITED STATES COURT OF APPEALS

FOR THE TENTH CIRCUIT

UNITED STATES OF AMERICA,

		Plaintiff-Appellee,

v.

DALE CHALLONER,

		Defendant-Appellant.	

No.  01-1075
(D.C. No. 00-CR-482-2-N)
(D. Colo.)	

ORDER AND JUDGMENT*

Before BRORBY, EBEL, and BRISCOE, Circuit Judges.

	After examining the notice of appeal and motion for stay, this panel has determined unanimously that oral argument would not materially assist the determination of this appeal.  See Fed. R. App. P. 34(a)(2); 10th Cir. R. 34.1(G).  The case is therefore ordered submitted without oral argument.
	Dale Challoner, proceeding pro se, appeals from the district court’s order denying his motion to suppress statements in his criminal prosecution, and seeks an emergency stay pending appeal of his trial set for February 26, 2001.  Although we construe Mr. Challoner’s pro se pleadings liberally, see Haines v. Kerner, 404 U.S. 519, 520-21 (1972), this court has a duty to examine its own jurisdiction in the first instance.  Maier v. EPA, 114 F.3d 1032, 1036 (10th Cir. 1997).  Because we conclude that the district court’s denial of Mr. Challoner’s motion to suppress is not a final, appealable order, we must dismiss this appeal for lack of jurisdiction.
	A ruling on a motion to suppress evidence in a pending criminal proceeding is interlocutory and not immediately appealable.  DiBella v. United States, 369 U.S. 121, 131 (1962); Blinder, Robinson & Co. v. United States (In re Search of Premises Known as 6455 S. Yosemite, Englewood, Colo.), 897 F.2d 1549, 1554 (10th Cir. 1990) (accord).  “Orders granting or denying suppression in the wake of [criminal] proceedings are truly interlocutory, for the criminal trial is then fairly in train.”  DiBella, 369 U.S. at 131.  Thus, we have no jurisdiction over such rulings.  Id.  Because appellate jurisdiction over the underlying appeal is a prerequisite for this court’s consideration of a stay pending appeal, Desktop Direct, Inc. v. Digital Equip. Corp., 993 F.2d 755, 756-57 (10th Cir. 1993), we must dismiss Mr. Challoner’s motion for stay as moot.
	Accordingly, Mr. Challoner’s appeal is DISMISSED for lack of jurisdiction, and his emergency motion for stay is DISMISSED as moot.
