My interpretation is that Pinochet can refuse to have the examinations, but at the same time the law obliges the investigating judge to request them.
If a criminal trial started against him, then it is very probable that the general dies before there is a verdict.
Public opinion will be focused on the protests against Bush.
Without a doubt, this is the worst birthday he could have from a judicial standpoint. This is by far the most delicate situation he's gone through.
This is his Achilles heel, the big headache for Pinochet and his defence lawyers. Unlike the human-rights accusations where it has been tough to prove a link between Pinochet and the crimes of his regime, in this case the numbers don't lie and the case could move forward very quickly.
