(CNN) – The U.S. Supreme Court ruled Monday that federal prosecutors were wrong to try a Pennsylvania woman for violating an international chemical weapons treaty.
Carol Ann Bond, a microbiologist, was accused of using an arsenic-based compound to poison a woman who was impregnated by Bond's estranged husband.
The high court says Bond should have been tried in the state courts and not the federal system.
In his opinion, Chief Justice John Roberts wrote, "The global need to prevent chemical warfare does not require the federal government to reach into the kitchen cupboard."
