Dissented, resisted (9)
I believe the answer is:
protested
This clue is a double definition.
'dissented' is the first definition.
('protest' can be a synonym of 'dissent')
'resisted' is the second definition.
('protest' can be a synonym of 'resist')
(Other definitions for protested that I've seen before include "Objected or remonstrated" , "Made objection or complaint" , "Uttered words of dissent" , "Dissented, resisted" , "Expressed disapproval, objected" .)
