Law incorrectly cited (5)
I believe the answer is:
edict
'law' is the definition.
(thesaurus)
'incorrectly cited' 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 "Legally binding command" , "Cited an official proclamation" , "Injunction" , "Decree, order" , "Formal proclamation" .)
