The Press fail to win in court (6)
I believe the answer is:
closet
'the press' is the definition.
(synonyms)
'fail to win in court' is the wordplay.
'fail to win' becomes 'lose' (synonyms).
'in' indicates putting letters inside.
'court' becomes 'ct' (abbreviation used in road names).
'lose' going within 'ct' is 'CLOSET'.
(Other definitions for closet that I've seen before include "Study" , "place to store gear" , "Tall cupboard, wardrobe" , "small compartment for clothing" , "Shut away in private conference - in small room?" .)
