We had a bit of a conversation Tuesday trying to unravel whether something is an exception to mootness (moot, but not dismissed) or not moot (so no basis to dismiss). Doctrinally it does not matter--either way, the case continues.
Normatively, we want precision, which is why we had the discussion. Note that it only matters for CRER. The voluntary cessation doctrine is expressly not mootness-if government cannot meet the high standard, the case is not moot and remains alive. Floating classes (in response to inherently transitory claims) make the claim not moot--it remains alive as to the class (independent of any individual plaintiff).
So the controversy surrounds CRER.
