Bothersome legal process (6)
I believe the answer is:
trying
'bothersome' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for trying that I've seen before include "Hearing (a case)" , "Hard to endure" , "Taxing" , "Testing" , "Aggravating" .)
