With no explanation, chose the best option from "A", "B", "C" or "D". 1228, 143 L.Ed.2d at 326 n. 6, 330-31 (construing federal carjacking statute that imposed enhanced punishment when offense resulted in serious bodily injury or death as defining separate offenses with distinct elements to avoid “serious constitutional questions” under Due Process Clause and Sixth Amendment’s notice and jury trial guarantees). Here, the defendant was charged with scheduled violations, yet the State sought to have him sentenced to jail on the basis it had proved he committed nonscheduled simple misdemeanors. Because the defendant had no notice he was being charged with the greater offenses, he clearly did not have constitutionally sufficient notice of the charges against him.
