Where one’s tried to go after discharge, reportedly (9)

I believe the answer is:
courtroom
'where one's tried' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'to go after discharge reportedly' is the wordplay.
'to go after' becomes 'court' (both can mean to romantically pursue someone).
'discharge reportedly' becomes 'room' (I can't justify this - if you can you should give a lot more credence to this answer).
'court'+'room'='COURTROOM'
Can you help me to learn more?
(Other definitions for courtroom that I've seen before include "trying situation" , "trial venue" .)
