As far as I can tell, it looks like the response was given after the Court action was filed. At this stage ASX is considering ISX's response to the proposal for reinstatement (pending some new terms I assume) but won't make a decision until the court date, at least not publicly.
It appears, at least on the face of it, that there is some road for ISX to be relisted. Whether ISX is willing to meet those demands remains to be seen. I would speculate that ISX has to make a decision as to whether they try for another resolution through a court ruling or just play ball with ASX. It seems ISX is willing to take some steps to rectify the situation but it's up to ASX to decide if it's enough.
