Update: Judge right? He's wrong (7)

I believe the answer is:

refresh

'update' is the definition.
(thesaurus)

'judge right? he's wrong' is the wordplay.
'judge' becomes 'ref'.
'right?' becomes 'r' (common abbreviation).
'wrong' is an anagram indicator.
'hes' anagrammed gives 'esh'.
'ref'+'r'+'esh'='REFRESH'

(Other definitions for refresh that I've seen before include "Reinvigorate" , "give life again to..." , "Revive, cheer" , "Give new vigour to" , "Restore strength with food or sleep" .)

I've seen this clue in The Guardian.
