"A breach would mean viable genetic material escaping the facility and pollinating outside ryegrass."
Dr Kardailsky claimed he was unjustifiably dismissed and sought interim reinstatement while an inquiry was done by the Employment Relations Authority (ERA).
But ERA member Michele Ryan ruled that Dr Kardailsky would not be reinstated in the interim. A full ERA hearing is scheduled for December.
