Is 18 U.S.C. § 3583(e) unconstitutional as applied?

QUESTION PRESENTED FOR REVIEW Is 18 U.S.C. § 3583(e) unconstitutional as applied to Mr. Cameron because his combined initial and revocation sentences exceed the statutory maximum punishment for his original offense? And is subsection 3583(e)(3) unconstitutional as amended in 2003 because the addition of the words “on any such revocation” to the limitations on revocation sentences resulted in the elimination of any statutory cap on sequential revocation sentences and permit a life sentence on the installment plan for each and every federal offense? This case presents an important question which the Courts of Appeals decline to address because of a continued failure to grapple with the fundamental difference between parole and supervised release. i
