In that case, William Lewis (the attorney so fancied by DL) represented the Defendant and cited Vattel to support quashing the indictment.
Lewis was opposed by William Rawle (the attorney DL thinks was the source of the English law based view DL opposes). The Court (James Wilson, a member of both the Continental Congress and Constitutional Convension) sided with Rawle, rejecting Lewis's Vattel-based argument.
Very good. :)
