Take legal action about shoddy stuff in work of art (6)
I believe the answer is:
statue
'work of art' is the definition.
(I've seen this in another clue)
'take legal action about shoddy stuff' is the wordplay.
'take legal action' becomes 'sue' (I've seen this in another clue).
'about' means one lot of letters goes inside another.
'shoddy stuff' becomes 'tat' (I've seen this before).
'sue' going around 'tat' is 'STATUE'.
'in' is the link.
(Other definitions for statue that I've seen before include "A carved image or effigy" , "Still work" , "Model figure" , "Large figure" , "Solid representation of the human form" .)
