What the tribunal could do is confirm my decision or require me to reconsider. Those are the two real options that they have. First of all, they can say the decision is correct and they confirm it. The second option is to refer the case back to the commissioner for reconsideration. Usually, they will give me legal arguments as to what I should consider, so those are the two steps that can occur; I am either confirmed or required to reconsider.
