directors independance

I'm quite concerned that there are already 3 new Directors proposed by Avoca who will sit on a Board that in 2 weeks time will give an opinion about the merits or otherwise of the offer from Ramelius Resources. How can those Directors as individuals with an allegiance to Avoca be expected to give shareholders an unbiased view about the proposed offer. As an interested party I will be expecting detailed reasons for their reccommendations (Or otherwise) . If there is any hint of partisanship then I believe they could become liable, as their duty of care must be to Dioro shareholders with no bias towards Avoca's interests.
