Right to give out terms of reference (5)
I believe the answer is:
'terms of reference' is the definition.
(I've seen this before)
'right to give out' is the wordplay.
'right' becomes 'r' (common abbreviation).
'to give out' becomes 'emit' (synonyms).
(Other definitions for remit that I've seen before include "instructions required", "Relax; send (payment)", "Send; abate; cancel", "Send back; scope of authority", "Send - scope of one's duties".)
