Ruled out of order but still patient (7)
I believe the answer is:
invalid
'patient' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for invalid that I've seen before include "Worthless - sick person" , "What Bunbury was, permanently" , "Disable" , "lacking legal authority" , "patient [found]" .)
