Why was Burr found not guilty for treason?

Answer :

On September 1, 1807, he was acquitted on the grounds that, although he had conspired against the United States, he was not guilty of treason because he had not engaged in an “overt act,” a requirement of treason as specified by the U.S. Constitution.
