Pass out seeing court enthralled by case of sedition (5)
I believe the answer is:
swoon
'pass out' is the definition.
('swoon' can be a synonym of 'pass out')
'court enthralled by case of sedition' is the wordplay.
'court' becomes 'woo' ('woo' can be a synonym of 'court').
'enthralled by' indicates putting letters inside ('enthral' can mean 'capture').
'case of' says to hollow out the word (remove centre letters) (outsides of).
'sedition' with its middle taken out is 'sn'.
'woo' going within 'sn' is 'SWOON'.
'seeing' acts as a link.
(Other definitions for swoon that I've seen before include "Display of extreme emotion" , "experience ecstasy" , "Lose consciousness" , "Faint (with emotion)" , "Pass out" .)
