I'm a little stuck... Click here to teach me more about this clue!

'prearranged conspiracy' is the definition.
(I've seen this in another clue)

I can't explain the rest of the clue.

(Other definitions for put-up job that I've seen before include "sham!" , "Dishonest scheme" , "Prearranged scam" , "Prearranged underhand deceitful enterprise" , "Craftily prearranged deed" .)

I've seen this clue in The Hindu.
