Frustrating but a bit of an overstatement. It will probably delay development by 6 months while they submit a new proposal.
It sounds a bit like Ramelius did not do all its paperwork:
"Ramelius on Wednesday said that during the appeals process, and based on feedback, the company revised the clearing of 48.8 ha of vegetation by reducing it to 26.3 ha; however, the Appeals Convenor only assessed the original application. The 26.3 ha proposal was acknowledged, but not assessed with the expectation that a revised application would be submitted by Ramelius
