Airservices Australia sought to establish copyright over the information in the Australian AIP in a court case filed in 2003.
I don't know whether that case is still in progress but interestingly in July 2006 Airservices Australia were
ordered by the Federal Court to pay the defendants' costs in respect of certain work.
COSTS – where substantial delay in proceedings caused by numerous attempts at amending the Application and Statement of Claim, directions hearings have been held which should not have been necessary and interlocutory steps taken and applications brought unnecessarily given the changes to the pleadings.
Held: the costs thrown away should be paid by the applicant forthwith.
AFIK no attempt has been made by UK AIS or the UK CAA to assert copyright on their data.
