Century by cricket side after chaps rolled over without dissent (3,3)
I believe the answer is:
nem con
'without dissent' is the definition.
('nem con' can be a synonym of 'without dissent')
'century by cricket side after chaps rolled over' is the wordplay.
I cannot quite understand how this works, but
'century' could be 'c' (common abbreviation) and 'c' is present in the answer.
'over' could be 'on' (I've seen this in other clues) and 'on' is found in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for nem con that I've seen before include "Latin abbrev. for unanimously, no one dissenting" , "with no opposition" , "With no one voting against" , "Notation meaning unanimous, with nobody dissenting" , "With no one dissenting from con men" .)
