b
copies of any such material are given to overseas authorities only if those requirements are met.

b
that restrictions are in force which would prevent, to such extent (if any) as the issuing authority considers appropriate, the doing of anything in, for the purposes of or in connection with any proceedings outside the United Kingdom which would result in a prohibited disclosure.
