Hearing about contrary central point of matter in court (8)
I believe the answer is:
tribunal
'hearing' is the definition.
(I've seen this before)
'contrary central point of matter in court' is the wordplay.
'contrary' shows that the letters should be reversed in order.
'central point of matter' becomes 'nub' (I've seen this before).
'in' means one lot of letters goes inside another.
'court' becomes 'trial' (trial court is a kind of court**).
'nub' in reverse letter order is 'bun'.
'bun' placed into 'trial' is 'TRIBUNAL'.
'about' is the link.
(Other definitions for tribunal that I've seen before include "Assembly to conduct judicial business" , "Special investigation team constituted in brutal mode" , "examination" , "Official board" , "case" .)
