If for any reason ANZ and OPES are found to have acted negligent in their business activities, I wonder if this gives them a legal right to freeze client accounts and sell their shares to recover lost money.
I understand that if any litigation action is taken this is the angle they might be pursuing.
Its possible that ANZ has acted legally in taking possession of security certificates...but its also possible that they may have acted illegally. Given there isnt any precedence in relation to this matter a decision by a court could go either way.
