Casino questions

Moin Khan and his wife are back in Pakistan and the casino saga has been resolved with the honourable acquittal of the chief selector.
A lot of hue and cry was raised in the media over the issue but no one asked the main question: Who authorised Moin Khan and his wife to travel with the World Cup squad and why? Is there any law that governs the selection of officials accompanying the cricket team on a foreign tour?
