Cancel terms of reference (5)
I believe the answer is:
remit
I believe this is a double definition.
'cancel' is the first definition.
(remitting is a kind of cancelling)
'terms of reference' is the second definition.
(I've seen this before)
(Other definitions for remit that I've seen before include "Send - scope of one's duties" , "Put off" , "forward" , "Defer" , "Task/area assigned (to an organisation)" .)
