This appeal provides the occasion for our en banc court to revisit and clarify the issue of plain error in criminal cases in this circuit. Convicted on a guilty plea of possession of ethyl ether with intent to manufacture amphetamine, Timothy Lynn Calverley challenges his sentence. Three of the аssigned errors were not raised in the trial court and do not constitute plain error. The fourth is without merit. We affirm.
Background
Calverley was arrested and indicted for possession of 2.5 gallons of ethyl ether with the intent to manufacture amphetamine.
On appeal Calverley urges, for the first time, three assignments of error. He maintains that the trial judge erroneously sentenced him as a career offender and retroactively applied two Guidelines sections in violation of the ex post facto clause. He also
Analysis
I.
One of the most familiar procedural rubrics in the administration of justice is the rule that the failure of a litigant to assert a right in the trial court likely will result in its fоrfeiture.
In U.S. v. Olano,
The second requirement is that the error be plain. Plain is synonymous with “clear” or “obvious,” and, “[a]t a minimum,” contemplates an error which was “clear un
Finally, to be reviewable under this standard an obviоus legal error must affect substantial rights. Olano counsels that in most cases the affecting of substantial rights requires that the error be prejudicial; it must affect the outcome of the proceeding.
II.
Upon finding that these elements of plain error are met, an appellate court is empowered, in its discretion, to correct the assigned error.
III.
Guided by the foregoing, we examine the facts of the instant case. As noted, Calverley raised three challenges for the first time on appeal, contending that the district court erred in sentenсing him as a career offender and in retroactively applying two sections of the Guidelines in violation of the ex post facto clause. Concluding that none of these claims meets the stringent requirements of the plain error test, wе decline to review their merits.
Calverley first asserts that possession of a listed chemical with intent to manufacture a controlled substance in violation of 21 U.S.C. 841(d) does not qualify as a controlled substance offense within the meaning of U.S.S.G. § 4B1.1, the career offender guideline. Prior to November 1, 1989, the accompanying definitional section
The uncertainty manifest in this area of the law illustrates that any error on the part of the trial court could not bе plain. Assuming without deciding that studied analysis of section 4B1.2(2) would lead to the conclusion that possession of a listed chemical with intent to manufacture a controlled substance is not a controlled substance offense, this conclusion was not obvious when the court sentenced Calverley as a career offender. Consequently, neither the trial judge nor the prosecutor may be considered derelict in failing to notice that one interpretation of the career offender guideline foreclosed that application.
Calverley next maintains that he was sentenced in violation of the ex post facto clause. He claims that the trial judge relied on commentary added to sectiоn 4A1.2
Assuming that the sentence was imposed in violation of the ex post facto clause, Cal-verley has failed to demonstrate prejudice. He must show that the outcome of his proceeding was affected by the error. Calverley has failed to carry his burden; he has not demonstrated how his sentence would have been different but for the alleged errors.
Calverley finally challenges the trial court’s denial of the request for a two-point reduction in offense level for acceptanсe of responsibility. Calverley properly voiced his objection at trial. We review the assignment of error. The original panel thoroughly considered and appropriately resolved this claim; we therefore reinstate and аdopt Part D of the panel opinion,
The judgment of the district court is AFFIRMED.
