21 U.S.C. § 332 — Injunction proceedings

(a) Jurisdiction of courts
The federal district courts, including the courts in the U.S. Territories, have the power to stop people from violating section 331 of this title. A court can issue this kind of order — called an injunction — whenever there's good cause to do so. This power doesn't cover every part of section 331, though. It doesn't apply to three specific parts of that section: paragraphs (h), (i), and (j).

(b) Violation of injunction
Suppose someone breaks an injunction or restraining order that a court issued under this section. If that same act also breaks a rule somewhere else in this chapter, here's how the case gets decided: normally, a judge decides the case alone, without a jury. But the accused person^* can ask for a jury trial instead. If they make that demand, a jury decides the case.
