In USA v. Seighman, the 3rd Circuit distinguished subsection (g) of the federal supervised release statute — 18 U.S.C. ยง 3583 — from subsection (k), which the Supreme Court in USA v. Haymond found to violate the 5th and 6th Amendments. Here, the Third Circuit ruled that mandating at least one day in jail for possessing drugs was not a constitutional violation.
