Bank upset about court orders (6)
I believe the answer is:
edicts
'orders' is the definition.
('edict' can be a synonym of 'order')
'bank upset about court' is the wordplay.
'bank' becomes 'side' ('side' can be a synonym of 'bank'**).
'upset' says the letters should be written in reverse.
'about' means one lot of letters goes inside another.
'court' becomes 'ct'.
'side' written backwards gives 'edis'.
'edis' enclosing 'ct' is 'EDICTS'.
(Other definitions for edicts that I've seen before include "Official orders or proclamations" , "Orders proclaimed by authorities" , "Official orders issued by authority" , "Commands" , "Decrees by authority" .)
