From Hong Kong’s statement on Edward Snowden’s departure:
“Since the documents provided by the US Government did not fully comply with legal requirements under Hong Kong law, the Hong Kong Government requested additional information so that the Department of Justice could consider whether the US Government’s request met relevant legal conditions.
“As the Hong Kong Government did not yet have sufficient information to process the request, there was no legal basis to restrict Mr Snowden from leaving Hong Kong.
“At the same time, it has formally written to the US Government requesting clarification on reports about the hacking of computer systems in Hong Kong by US government agencies. It will follow up on the matter, to protect the legal rights of people of Hong Kong.”
