Prosecuted for ruining garden air (9)
I believe the answer is:
arraigned
'prosecuted' is the definition.
The definition and answer can be both to do with social activities as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'ruining garden air' is the wordplay.
'ruining' indicates anagramming the letters.
'garden'+'air'='gardenair'
'gardenair' with letters rearranged gives 'ARRAIGNED'.
'for' is the link.
Can you help me to learn more?
(Other definitions for arraigned that I've seen before include "Called before a court to answer an indictment" , "accused" , "Indicted" .)
