Censure Bury detective attending court (9)
I believe the answer is:
interdict
'censure' is the definition.
(interdict is a kind of censure)
'bury detective attending court' is the wordplay.
'bury' becomes 'inter' (I've seen this before).
'detective' becomes 'di' (Detective Inspector abbreviation).
'attending' means one lot of letters go next to another.
'court' becomes 'ct'.
'inter'+'di'+'ct'='INTERDICT'
(Other definitions for interdict that I've seen before include "An authoritative prohibition, maybe by church" , "Prohibit, forbid" , "Credit tin (anag) - ecclesiastical sanction" , "Court order" , "Prohibit - tin credit (anag)" .)
