I believe the answer is:

'expresses opposition' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for dissents that I've seen before include "goes with schism?" , "Thinks differently" , "Expresses opposition" , "Expresses a different opinion" , "Disagrees, takes different view" .)
