Righteous, law-abiding (7)
I believe the answer is:
upright
This clue is a double definition.
'righteous' is the first definition.
(similar in meaning)
'law-abiding' is the second definition.
(thesaurus)
(Other definitions for upright that I've seen before include "honestly" , "Pig hurt (anag) -- noble" , "with principle" , "Erect - post" , "Good" .)
