For purposes of s 117(6) of the Criminal Procedure and Evidence Act, a defence outline does not constitute 'evidence' sufficient to discharge the onus of proving exceptional circumstances. A defence outline is merely an assertion or summary of an intended defence, whereas evidence is the mode of proving or disproving such assertions. Section 117(6) overrides other bail provisions in the Act by virtue of its opening phrase 'Notwithstanding any provision of this Act', and sets a higher standard of proof through the requirement of 'exceptional circumstances' - a standard that takes the burden outside common human experience and ordinary practice. Accused persons charged with killing law enforcement officers must adduce actual evidence, not mere assertions, to satisfy the court that exceptional circumstances exist warranting their release on bail.
