To suppress frauds you need the courts (6,7)
I believe the answer is:
squash rackets
'the courts' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'to suppress frauds' is the wordplay.
'to suppress' becomes 'squash' (I've seen this in another clue).
'frauds' becomes 'rackets' (I've seen this before).
'squash'+'rackets'='SQUASH RACKETS'
'you need' is the link.
Can you help me to learn more?
(Other definitions for squash rackets that I've seen before include "Court action" , "put an end to fraudulent schemes" , "Game" , "they'll be needed in court" , "sport" .)
