Suspension or not, the Directors have a responsibility to keep the market informed. So long as the suspension is in place there is no impact on the SP should they "tell it as it is", other than what will take place when the suspension is lifted. Nor can they plead commercial sensitivity because the only other party involved is Quantum Minerals who are already in default of payment.
All of which makes one wonder if the suspension is really to protect QM rather than BEZ, in which case, is there not a case to answer with the ASX and ASIC?
If QM goes bust, then BEZ can survive, as others have pointed out, although new directors should be appointed.
As I said at the start of this post, "so long as the suspension is in place there is no impact on the SP should they "tell it as it is", other than what will take place when the suspension is lifted." (which reaction will happen regardless). Meanwhile, the Directors have an obligation to inform the market.
