Checks rules written by pub for hearing (5,2)

Ross

I believe the answer is:

reins in

'checks' is the definition.
(I've seen this before)

'rules written by pub for hearing' is the wordplay.
'rules' becomes 'reins' ('rein' can be a synonym of 'rule').
'written by' is a charade indicator (letters next to each other).
'pub' becomes 'inn' (an inn is a type of pub).
'for hearing' shows a homophone (sound like).
'inn' sounds like 'in'.
'reins'+'in'='REINS IN'

(Another definition for reins in that I've seen is " Checks".)

I've seen this clue in the Sydney Morning Herald.
