What it's about
The Supreme Court ruled that the law did not cover Bond’s simple assault, overturned the appeals court’s decision, and sent the case back to it (remanded it).
Bond used chemicals in an attempt to harm her husband’s pregnant friend, who suffered a minor burn. The federal government prosecuted Bond under the law implementing the Chemical Weapons Convention.
Congress passed the Chemical Weapons Convention Implementation Act to carry out a treaty on chemical weapons in U.S. law.
Question presented
1. Does Congress have the authority to enact legislation that enforces a treaty but goes beyond the scope of the treaty and intrudes on traditional state prerogatives? 2. Can the Chemical Weapons Convention Implementation Act be properly interpreted so that it does not apply to ordinary poisoning cases, which have been traditionally handled by state and local authorities?
What the Court decided
Holding
Section 229 does not reach Bond’s simple assault. 681 F. 3d 149, reversed and remanded.
- Result
- Reversed
The Court's reasoning
The Court read Section 229 as not reaching Bond’s simple assault. That let it resolve the case without deciding Congress’s broader power to enforce treaties.
