Guys, brains please! Ulrich, Basso and Scarponi are not Spanish. Their respective racing federations in Italy and Switzerland asked for the evidence and had legal precedent to use it. Spains laws at the time did not allow authorities to do squat.
I am fed up with the posturing and simple mindedness of some people here on this forum with this matter. The Spanish Minister for Sport in 2006 was furious! She was ****ed, upset and shocked, like you are, but knew that legislation needed to have been in place in 2006 for any criminal charges to stick for straight out doping. This has been mentioned dozens of times over the past 12 months. If you were to lazy or stupid to figure this out then consider this your lesson. The Spanish were not protecting anyone. You will never be able to prove that, because the legislation to formally charge a rider as not in place. It is now.
Did Valverde dope? Name me a top 10 GC rider the past 20 years who hasn't or you have no reason to suspect was not doing what the other boys were. Some of the self righteous misinformed opinions on here are really irking.

You can all sit at home and think to yourself that Valverde is another doper, but according to Spanish jurisdiction he has nothing to answer for. Whose fault is that? Spanish Parliament for not suspecting something like OP would ever take place? Perhaps but with most shocking and dirty behaviour, once committed, acts are taken to punish other offenders. The Spanish are only really naughty if they knew and did nothing. Prove that. As for the lack of legal paths to take against dopers; Did they rectify this? You bet. Get over it and come back down to earth. Numerous guys have posted rhetorical questions and some of you are still trying to wiggle and worm your way to the moral high ground. There is none. Especially in sports where people dope. You have to follow the law and that is it. CONI tried to be sneaky and should be called out. So too CAS. If you don't respect basic laws, where can you ever draw the line? You cannot break one law to uphold another. I know it sucks but people have to get it right. Rant over.
Can anyone explain to me level of authority European Courts have. Can CAS overturn a Spanish Court? I didn't think they could. If Valverde went to the European High Court would they declare any negative CAS ruling "illegal and beyond their scope and ruling?" Because if this happened in Australia, you'd have been told to go F%#K yourself. Charming isn't it?
