Plea's outcome, possibly a foregone conclusion (2,7)
I believe the answer is:
no contest
This clue could be a double definition.
'plea's' is the first definition.
(I've seen this before)
'foregone conclusion' is the second definition.
(both refer to a predictable result)
'outcome possibly a' acts as a link.
I am not very happy about this link. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for no contest that I've seen before include "The winner is obvious!" , "plea" , "Without serious competition -- hands down" , "a foregone conclusion" , "one-sided fight?" .)
