The deal was simple: Go home. Shut up. If you dare to say you had no choice but to plead guilty, the US Military Commission will find you guilty of perjury and will call in a full seven-year sentence, over and above the five you've suffered unconvicted and uncharged. That will mean the Australian Attorney-General may not release you on licence for another seven years, or will — with the additional gags of control orders and other available means — make sure you cannot tell anyone what happened.
Apart from the loss of fundamental guarantees of freedom, another freedom — speech — is garrotted.
The best thing one can say about the process is that one day there may be a reckoning for this despicable episode, in which Australian ministers, all the way down from the Prime Minister, have been party to the commission of grave crimes under the Australian Criminal Code 1995, divisions 104 (Harming Australians Overseas) and 268D (denying a fair trial), because they have been criminally complicit under section 11.2.
By the time the US Supreme Court strikes down the whole festering sore in a couple of years — which most constitutional lawyers believe it will — we can only hope there will be another attorney-general in Australia who will have the guts to authorise proceedings against those who "aided, abetted, counselled or procured" the commission of the crimes to which I have referred. Let us not forget the war crimes trials after World War II, in which the German Nazi judges who prostituted their duty in the service of the political ideology that put them there were put on trial for what they did.
