text: In June 2002, West Australian resident Rob Hall was convicted for using a canister of pepper spray to break up an altercation between two guests at his home in Midland. He was sentenced to a good behavior bond and granted a spent conviction order, which he appealed to the Supreme Court. Justice Christine Wheeler ruled in his favor, thereby legalizing pepper spray in the state on a case-by-case basis for those who are able to show a reasonable excuse.
  On 14 March 2012, a person dressed entirely in black entered the public gallery of the New South Wales Legislative Council and launched a paper plane into the air in the form of a petition to Police Minister Mike Gallacher calling on the government to allow civilians to carry capsicum spray.
