Consider US lawyer's twisted justice (7)
I believe the answer is:
adjudge
'consider' is the definition.
(thesaurus)
'us lawyer's twisted justice' is the wordplay.
'us lawyer' becomes 'da' (abbreviation for District Attorney).
'twisted' shows that the letters should be reversed in order.
'justice' becomes 'judge' ('judge' can be a synonym of 'justice').
'da' in reverse letter order is 'ad'.
'ad'+'judge'='ADJUDGE'
(Other definitions for adjudge that I've seen before include "Give verdict" , "Value" , "Decree" , "Decide or award judicially" , "Decide formally" .)
