I would use Law 57 C3. If the lead from Dummy is accepted, then I would judge the declarer's played card is considered premature. So under 57C3, cannot be retracted. The OS should be prepared to accept such a ruling. Dura lex, sed lex.

My view is that the 2 ♥ opening would not be a psyche ( a gross misstatement of strength or suit) in Oz. If partner seldom made such a bid (less than say 2 or 3 times a year as a guide), then there is no real partnership understanding. No self reporting for psyches that I know of in Oz. No need to call the director by E/W (why would you?). If N/S called, the Director after investigating the best they could (again afaik no national psyche database), would have no cause to adjust the score.
