Club's bill rejected (3)
I believe the answer is:
Here is my best explanation:
'club's' is the definition.
(bat is a kind of club)
'bill rejected' is the subsidiary indication.
'bill' becomes 'tab' (tab is a kind of bill).
'rejected' says the letters should be written in reverse.
'tab' back-to-front is 'bat'.
(Other definitions for bat that I've seen before include "Vampire - -", "Club used in cricket", "A small winged mammal", "A mammal; a club", "Small flying mammal, may be vampire", "opener, for instance", "once wielded by 60 [GREIG]", "Cricket club", "Cricket, table-tennis and baseball implement" and "Cricketer; mammal".)
