High Court writ dismissing case stops a corporation (6)
I believe the answer is:
atrium
'high court writ' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'dismissing case stops a corporation' is the wordplay.
'dismissing case' becomes 'ri' (I can't explain this - if you can you should give a lot more credence to this answer).
'stops' indicates putting letters inside (stopping can mean blocking a gap).
'corporation' becomes 'tum' ('corporation' can humorously mean belly fat).
'a'+'tum'='atum'
'ri' inserted into 'atum' is 'ATRIUM'.
Can you help me to learn more?
(Other definitions for atrium that I've seen before include "An upper chamber of the heart" , "Central area in a building, open or glass-roofed" , "An upper cavity in the heart" , "Central hall or court" , "Central court of old Roman house, or heart cavity" .)
