Whether 18 U.S.C. § 924(c)(1)(C) precludes aggravated punishment for second firearms convictions unless the second violation 'occurs after a prior conviction' 'becomes final', and expressly applies to 'pending cases' involving offenses 'committed before the date of enactment'

QUESTION PRESENTED Whether 18 U.S.C. § 924(c)(1)(C), which as clarified and as amended by the First Step Act of 2018, precludes aggravated punishment for second firearms convictions unless the second violation “occurs after a prior conviction” “becomes final,” and expressly applies to “pending cases” involving offenses “committed before the date of enactment,” should have invalidated two 25-year stacked sentences in this case where the defendant had been sentenced, but his convictions were not final, on the date of enactment. i
