We have to understand how the business is carried out, and the case I have quoted provides a partial illustration of that. 26.

Very briefly it is this: given the methods to which sanctions busters resort, if the Committee is to succeed in its task of detecting sanctions evasions and of assisting Governments which profess to support sanctions in their task of detecting evasions, the Committee cannot ignore the technicalities. There is indeed a lot of hard, down-to-earth technical work to be done. Despite the complexities, however, one thing which is clear is that as far as goods imported from Southern Rhodesia are concerned there is one place where an evasion of sanctions can be firmly and definitively established and that is at their port of final destination. The same principle is true of goods exported to Southern Rhodesia; it is in their country of origin that the investigations have to be made. 27.

But though there are undoubtedly many more cases which go unreported and undetected, and even unsuspected, not even all the 143 cases are proved.
