                           ORDER AND JUDGMENT *


Before BRORBY, BARRETT, and MURPHY, Circuit Judges.


      Petitioner Big Horn Coal Company (“Big Horn Coal”) seeks review of a

final order of the United States Department of Labor Benefits Review Board

(“Benefits Review Board”) directing Big Horn Coal to make black lung



      *
       This order and judgment is not binding precedent, except under the
doctrines of law of the case, res judicata and collateral estoppel. The court
generally disfavors the citation of orders and judgments; nevertheless, an order
and judgment may be cited under the terms and conditions of 10th Cir. R. 36.3.
compensation payments to Mr. David Steele, the claimant. The Benefits Review

Board affirmed an order of a United States Department of Labor Administrative

Law Judge (“ALJ”) finding that Mr. Steel had pneumoconiosis under 20 C.F.R. §

718.202(a)(4), that Mr. Steele was totally disabled, and that he was entitled to

disability benefits because his pneumoconiosis was a “contributing cause” of his

total disability under 20 C.F.R. § 718.204(a), 718.204(b) and 718.204(c)(5). Both

the ALJ and the Benefits Review Board applied this court’s decision in Mangus v.

Director, OWCP, 882 F.2d 1527 (10th Cir. 1989) in concluding that Mr. Steele

was entitled to disability benefits. In Mangus, this court set forth the standard to

be used in interpreting 20 C.F.R. § 718.204(a): “if the pneumoconiosis is at least

a contributing cause, there is a sufficient nexus between the pneumoconiosis and

the total disability to satisfy claimant’s burden of proof.” Id. at 1531-32.

      Big Horn Coal contends that the Mangus “at least a contributing cause”

standard should not be applied in this case. Instead, it asks this panel to impose a

“preponderance of the substantial evidence” standard. This we cannot do. One

panel of this court cannot overrule the decision of another panel. United States v.

Zapata, 997 F.2d 751, 759 n.6 (10th Cir. 1993); United States v. Spedalieri, 910

F.2d 707, 710 n.3 (10th Cir. 1990). Mangus provides controlling precedent for

this case and we are bound to apply it. After reviewing the record on appeal, this

court concludes that the Benefits Review Board properly found the ALJ’s


                                          -2-
decision to be supported by substantial evidence. Wyoming Fuel Co. v. Director,

OWCP, 90 F.3d 1502, 1505 (10th Cir. 1996). The final order of the Benefits

Review Board is hereby AFFIRMED. Big Horn Coal’s motion to allow a late

filing of an initial en banc suggestion is DENIED. 1

       Big Horn Coal filed its motion after oral argument and while the case was
under advisement. The panel is unaware of any rule, practice, or logic
authorizing such an unorthodox motion.
