Top soldier concealing mistake upheld in court, right? (7)

I believe the answer is:
correct
'right?' is the definition.
('correct' can be a synonym of 'right')
'top soldier concealing mistake upheld in court' is the wordplay.
I cannot quite see how this works, but
'soldier' could be 're' (Royal Engineer) and 're' is found within the answer.
'court' could be 'ct' (abbreviation used in road names) and 'ct' is found in the answer.
The remaining letters 'cor' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for correct that I've seen before include "Rectify" , "See 6" , "Set right - punish" , "Adjust, make right" , "Right a wrong" .)
