Going on past history I think Mr Amaral's present legal team will string out the process for as long as that can be done, then no doubt their successors will follow suit.
I don't think he was ever in any great hurry to have this court case resolved ... and with the recent judgement I am beginning to see why that was ... he has gone through some of the best legal minds in Portugal who perhaps gave him advice not to his liking. He's in no hurry as long as loyal supporters are picking up his tabs.
He will have very limited scope for that. The courts are well aware of the tactic of the losing party trying to spin things out as long as possible.
Justice delayed is justice denied, and if he tries something like a last minute does of bird flu, he will find judgement finalised and executed, and the sequestered funds distributed with costs crystallised.
He has the money for advice and to lodge an appeal on time, so he has absolutely no reason not to.
