Yup heard of Gunns, living tin Tas we all have. If they have not got rid of him and he had the 2nd opp while on their watch he would have a pretty good case. As for time frames, most specialists will not give a final until 12 onths after that type of operation. He needs to reach what they deem as MMI or maximum medical improvement. Only then will the Doctor give a final certification. Once he gets to MMI, he can also be assessed for whole person imparement as well.
