Beer drunk? Inebriated, leaving court with a jaunty air (6)
I believe the answer is:
breezy
'with a jaunty air' is the definition.
'beer drunk? inebriated leaving court' is the wordplay.
'beer drunk?' becomes 'bree' (I can't explain this - if you can you should believe this answer much more).
'inebriated' becomes 'woozy'.
'leaving' is a deletion indicator.
'court' becomes 'woo' ('woo' can be a synonym of 'court').
'woozy' with 'woo' taken out is 'zy'.
'bree'+'zy'='BREEZY'
(Other definitions for breezy that I've seen before include "Fresh and animated" , "Slightly windy" , "Blowy" , "Fresh - jaunty" , "Pleasantly windy" .)
