I still think he's innocent, not that it matters...

I still firmly believe that Contador is innocent and that it was in fact the meat that he ate. Unfortunately, the CAS feels different:

 CAS sanction Contador with two year ban in clenbuterol case

The Court of Arbitration for Sport has handed Alberto Contador a two year sanction for his positive test for clenbuterol at the 2010 Tour de France. After a long-running saga, CAS announced on Monday that it had upheld the UCI and WADA’s joint appeal against the Spanish Cycling Federation’s (RFEC) decision not to suspend Contador.

The ban means Contador will lose race results dating back to and including the 2010 Tour de France. Andy Schleck will become the Tour de France champion while Michele Scarponi is crowned winner of the Giro d'Italia.

Contador's ban ends on August 5th, meaning he can ride this year's Vuelta.

A long-running saga

Contador’s positive test dates from July 21, 2010, although the case was not made public until September 30 of that year. In February 2011, the RFEC officially cleared Contador, accepting his explanation that the traces of clenbuterol in his sample had been caused by consuming contaminated meat.

In March, both the UCI and WADA formally announced their decision to appeal the matter to CAS, who in turn announced that a ruling would be made ahead of the Tour de France.

That turned out to be a false dawn, however, and after a number of delays, the hearings were finally held in November 2011. In the intervening period, Contador had added to the Giro d’Italia to his palmares and finished fifth at the Tour de France.

The hearing itself was tinged with some degree of controversy, with AP reporting that WADA’s lawyers threatened a walk out when anti-doping expert Michael Asheden was not permitted to testify on the theory that Contador may have had a blood transfusion on July 20.

A verdict was initially due in mid-January, but was again delayed after Leopard Trek backer Flavio Becca questioned the integrity of CAS arbitration panel head Ephraim Barak. After confirming that none of the parties involved in the case wanted to change the make-up of the arbitration panel, CAS finally issued its verdict on Monday.

Contador still has the option of appealing the CAS ruling to the Swiss federal court within the next 30 days, although any such petition can only concern procedural matters.

Although, I do like Andy Schelck's response:

Andy Schleck reacts to Contador's doping ban

(http://www.cyclingnews.com/news/andy-schleck-reacts-to-contadors-doping-ban) 

Andy Schleck has reacted to the news that Alberto Contador has been handed a two year sanction by the CAS. Schleck finished second to Contador during the controversial Tour de France in 2010, in which traces of clenbuterol were found in one of Contador’s test samples.

"There is no reason to be happy now”, Schleck said in a RadioShack-Nissan press release

“First of all I feel sad for Alberto. I always believed in his innocence. This is just a very sad day for cycling. The only positive news is that there is a verdict after 566 days of uncertainty. We can finally move on.”

Contador faces all race results being stripped from him since and including the Tour title in 2010, meaning Schleck, who has never won a stage race, will become the official race winner.

“I trust that the CAS judges took all things into consideration after reading a 4,000 page file. If now I am declared overall winner of the 2010 Tour de France it will not make me happy. I battled with Contador in that race and I lost. My goal is to win the Tour de France in a sportive way, being the best of all competitors, not in court. If I succeed this year, I will consider it as my first Tour victory.”
