Against the law in bill I cited (7)
I believe the answer is:
illicit
'against the law' is the definition.
(thesaurus)
'in bill i cited' is the wordplay.
'in' says the answer is hidden in the clue.
'ILLICIT' is hidden in the letters of 'bill i cited'.
(Other definitions for illicit that I've seen before include "Felonious" , "not conforming to regulations" , "Contrary to or forbidden by law" , "Forbidden by law, rules" , "Under the counter" .)
