The way I read this mess is that at 9:52 NEA requested a halt to trading under 17.1 which was granted by the ASX. At 11:32 the ASX changed the basis under which NEA was suspended from 17.1 to 17.3. I suspect that this change means that NEA is allowed to trade again only when the ASX is satisfied with the process; which means that NEA management will have to pay a speeding fine of some sort.
