Law cited incorrectly (5)
I believe the answer is:
edict
'law' is the definition.
(I've seen this before)
'cited incorrectly' is the wordplay.
'incorrectly' indicates an anagram (I've seen this in other clues).
'cited' with letters rearranged gives 'EDICT'.
(Other definitions for edict that I've seen before include "An official command" , "Authoritative ruling" , "Cited an official proclamation" , "Legally-binding order" , "Legally binding command" .)
