Several companies breach listing rules on a regular basis. ASX doesn't routinely suspend them.
Companies are investigated by ASIC and AUSTRAC, etc. on a regular basis. None of them routinely asks ASX to suspend them; in fact, they prefer the investigations are done covertly.
Why is ISX being treated differently?
ASIC has been investigating (or pretending to be investigating or whatever) for months with no results or comments to show for it. ASIC has said it didn't request the initial suspension and it's up to ASX to lift it.
ASX published a dubious SOR as the basis for suspension and prevented ISX from publishing a response through the same medium so as to reach the same audience. Why?
