An illegitimate immigration incident involving Jennifer Robinson, the Australian lawyer for WikiLeaks founder Julian Assange, occurred at London's Heathrow Airport late on April 18. Jennifer Robinson was informed that she could not board a plane to Australia until she was cleared by the Australian High Commission. Using Twitter, she informed her followers: "Just delayed from checking in at LHR because I'm apparently 'inhibited' - requiring approval from Australia House to travel." Robinson added that an immigration security guard told her: "You must have done something controversial because we have to phone the embassy."
