The Declaration of War Against the Traitorous Jedi Order was both a declaration of war and a speech given by Darth Verraeter. It stated that since the Jedi had failed to uphold Republic law, they would be branded as heretics and were ordered to repent or be executed.
The Republic thought this was a little bit drastic, but relented because of their laws. A couple more smarter Admirals, ordered their ships to defect to the Order and began a guerilla war against the Der Hintergedanke.
