I predict, sadly, that the best Glen can hope for is a draw because CASA has the legal resources to take him all the way to the high court. The legal system is not known for producing justice.
CASA has the motivation to do this because the threat of unfettered, capricious and unjust persecution as allegedly inflicted on Glen and many others (see the Forsyth review) is the key source of their power.
All the best.
