Possessed more, being at court (3,2)
I believe the answer is:
had up
'more being at court' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'possessed' is the wordplay.
I cannot really see how this works, but
'possessed' could be 'had' (to have something is to possess it) and 'had' is found within the answer.
The remaining letters 'up' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for had up that I've seen before include "being courted" , "Put on trial" , "Brought before the court" , "Called to account before a court" .)
