I know this is a shot in the dark after 3 years but I am going through this process now too. However, I already have a message to separate, but the legal assistant at my command said I will be held until my ADSEP process finishes. From the legal assistance practice advisory 3-16, I'm seeing that with a GEN or above characterization, the DES runs until it is complete, but I have not found anything on where it is stated that the separation authority has to be involved in both. Do you have the instruction stating in which cases are prone to both processes running complete? Thanks
