From the blog:
"Ms. Pipkin said that Ms. Mustafa Kamal had sent her a copy of the “no-board” instructions which the DHS gave to Malaysia Airlines, and which the airline gave to Ms. Mustafa Kamal to explain as much as it knew about why it was not being allowed to transport her. Ms. Pipkin handed Judge William Alsup a copy of the DHS “no-board” instructions to Malaysia Airlines regarding Ms. Mustafa Kamal.
Major props to Malaysia Airlines for providing a copy of the DHS instructions to Ms. Mustafa Kamal. Other airlines receiving similar instructions have acquiesced to DHS orders to keep the instructions from the DHS, and the reasons for the airlines’ actions, secret from the would-be travelers whose rights are affected. So far as we know, this is the first time an actual no-fly order has been disclosed to a would-be traveler or potentially to the public."
Let's assume that (hopefully for the plaintiff) all of the above is true. If so, the copy of the "no board" instructions that is currently in the Judge's hands is hearsay, at least as of now. It could be supported by 1. Mustafa Kamal stating under oath that she received it and 2. Malaysia Airlines stating under oath that they issued it, and that it is true and accurate.
Now Malaysia Airlines could hypothetically spill the beans about everything, both to the court and to the public. But will they? I'd bet that the DHS already has its overseas henchmen working to ensure that Malaysia Airlines only reports the officially DHS sanctioned version of the "truth" to the court.
