Supreme Court to weigh weapons law in spurned lover case (Reuters) - The Supreme Court on Friday agreed to hear a new appeal by a woman convicted under a federal law intended to combat chemical weapons of trying to poison a former friend who had an affair with her husband. The case of Carol Anne Bond, a trained microbiologist who once worked at the chemical company Rohm and Haas Co, could give the court a chance to revisit a 1920 precedent written by Justice Oliver Wendell Holmes that gave Congress broad authority to adopt laws implementing treaties.
