Francisco Nolasco, an illegal alien, appeals from his conviction on 19 counts of harboring illegal aliens in violation of 8 U.S.C. § 1324(a)(1)(C). Nolasco contends that the district court erred in denying his request that the jury be instructed on the meaning of the term reasonable doubt. This court was first presented with the issue of when the trial court must define reasonable doubt for the jury in
United States v. Witt,
Subsequently, in
United States v. Wosepka,
Both parties have argued that the distinction between a "complex” case and a “straightforward” one is arbitrary and unworkable and have asked us to adopt a flat rule one way or the other regarding instructions defining reasonable doubt. The respective arguments of the parties contain no surprises. The government argues that the term “reasonable doubt” is self-explanatory and that no instruction regarding its meaning is needed in any case; conversely, the appellant argues that, because of the central role the concept of reasonable doubt plays in our criminal justice system,
Wosepka,
As a three-judge panel, we are, of course, without the power to reconsider the law of the circuit established in
Witt
and
Wosepka. Christoffel v. E.F. Hutton & Co.,
Notwithstanding the above, as we have already noted we are bound by Witt and Wosepka. Because we conclude that the issues and evidence in this case are simple and uncomplicated, we hold that the district court did not abuse its discretion in *680 refusing to give the requested instruction. Thus, we must affirm the conviction.
Nolasco also contends that 18 U.S.C. § 3013 is unconstitutional and that the district court’s assessment of a $50 fine against him on each count pursuant to that section was improper. We agree. We have recently held that 18 U.S.C. § 3013 was enacted in violation of the origination clause of the Constitution.
United States v. Munoz-Flores,
AFFIRMED IN PART, VACATED IN PART.
Notes
. We note that both parties in this case originally requested the instruction but that the government subsequently withdrew its request.
