I have not had experience with the internal review process. Frankly, I am of the opinion that it is mostly a window-dressing process at the moment. Were there an independent process, I think the model for the process could be adopted either from judicial complaints or from, for example, university complaints, There ought to be someone trauma informed and knowledgeable in medicine—they call them patient navigators—at the intake point who understands the context and the situation of a queer claimant wanting to make a complaint who could then assist them with the process. It wouldn't necessarily have to be lawyer driven.
