Equitable dealings out of order in this business meeting (5,4)
I believe the answer is:
trade fair
'equitable dealings out of order in this business meeting' is the definition.
'trade fair' can be an answer for 'business meeting'. I am not certain of the remainder of the definition.
'in this business meeting' is the wordplay.
'in this' becomes 'fair' (I am not sure about this - if you are sure you should believe this answer much more).
'business' becomes 'trade' (trade is a kind of business).
'meeting' means one lot of letters go next to another.
'fair' after 'trade' is 'TRADE FAIR'.
(Other definitions for trade fair that I've seen before include "sales show" , "Business gathering dealing with particular class of product" .)
