If I was 'charged by CASA' and the charges were in fact 'thrown out' by the court, I'd be on pprune in a microsecond, publishing the what, where and when in minute detail, and I would be perfectly entitled and free to do that. Courts don't order people not to reveal that charges against them have been dismissed.
Unless of course you were signatory to a deed that stopped you from doing so, is this possible Creampuff ?, often the case if there are damages associated with the event, be it accepting liability or to avert further legal action, I do not know this to be the case, but is plausable.
