I remember when looking into BQT a while back that there was some issue over an ASX annoncement being pulled or withdrawn and that this couldn't be done. Could someone who knows what happened give me a quick summary of wether or not this was actually done or did the ASX tell them to go jump?

I am not asking specifically about BQT and their involvement but more about under what circumstances it can be done or not - I have another stock I have been trying to accumulate and all their presentations since Oct have been pulled off the ASX and re issued without certain information in it and I was pretty damn surprised the ASX agreed to do it!
