Offence of men renting if thrown out (12)
I believe the answer is:
infringement
'offence' is the definition.
(I've seen this before)
'men renting if thrown out' is the wordplay.
'thrown out' indicates an anagram.
'men'+'renting'+'if'='menrentingif'
'menrentingif' anagrammed gives 'INFRINGEMENT'.
'of' is the link.
(Other definitions for infringement that I've seen before include "Violation of law" , "Breaking (of a law, etc)" , "Offence" , "Minor lawbreaking" .)
