Not sure what you’re asking.
Discovery is SOP. What’s unusual here is Judge Sullivan ordering ALL evidence for in camera review whether Mueller thinks it’s material or not.
That is my understanding. But Judge Sullivan has been prostelising for all judges to give a Brady warning ever since 2008, when he presided in a trial in which the defendant actually was not given all exculpatory evidence, and the judge found he was unable to adequately sanction the prosecutors for their abuse of the defendants rights.Judge Sullivan even put a special prosecutor on the case to try to punish the prosecutors - and was told that without having been given a Brady warning, the prosecutors could skate with, basically, a slap on the wrist.
