Australia's High Court reinstated a terrorism conviction Friday against a former Australian airline worker who published on the Internet a do-it-yourself book on how to wage holy war against non-Muslims.

The five judges unanimously overturned a lower court's 2-1 majority decision that had quashed Sydney resident Belal Sadallah Khazaal's conviction for producing a book knowing it was connected with assisting in a terrorist act. There was no evidence that it had resulted in a terrorist attack.

The charge was created in 2002 as part of a raft of tough new Australian terrorism laws legislated in response to the Sept. 11, 2001, attacks on the United States.

Khazaal, a 42-year-old former Qantas Airways employee, in 2003 became one of the first terror suspects to be charged under the laws.

The 110-page e-book advocated widespread assassinations, identified targets and outlined numerous methods of killing. It recommended shooting down planes and described how to make bombs.
