MELBOURNE (Reuters) - World no.1 tennis player Novak Djokovic is waiting to hear whether Australia will seek to cancel his visa for a second time, after being released from immigration detention three days ago when a court ruled he could stay. Australia's Immigration Minister Alex Hawke faces a tight timeframe to decide whether to exercise his power to cancel Djokovic's visa, as the Australian Open, the year's first tennis major, is due to start on Monday. ON WHAT GROUNDS COULD DJOKOVIC'S VISA BE CANCELLED? The immigration minister has the right to exercise his personal power to cancel a visa if he deems it would be in the public interest to do so. WHAT HAPPENS IF THE MINISTER DECIDES TO CANCEL HIS VISA?
