Seems in order for retributive justice (7)
I believe the answer is:
nemesis
'retributive justice' is the definition.
(thesaurus)
'seems in order' is the wordplay.
'order' indicates anagramming the letters.
'seems'+'in'='seemsin'
'seemsin' is an anagram of 'NEMESIS'.
'for' is the link.
(Other definitions for nemesis that I've seen before include "Goddess of revenge - seems in (anag)" , "causes downfall" , "Destiny" , "opponent you can't beat" , "E'en miss (anag.)" .)
