Contador's clenbuterol case in brief

Alberto Contador, Giro d'Italia 2011

On November 21, 2011, Alberto Contador's positive test for banned substance clenbuterol at the 2010 Tour de France was brought before a panel at the Court of Arbitration for Sport (CAS) in Lausanne, Switzerland, to determine whether the Spaniard should be suspended from competition.

As positive dope tests go, the case has been a complicated one. Contador tested positive for a minute dose of clenbuterol and has staunchly maintained that he must have ingested the substance unwittingly via a beef steak tainted with the substance.

However, clenbuterol is not a naturally-occurring substance and is banned at any level by the World Anti-Doping Agency (WADA). Currently, the onus is also on the athlete to be responsible for any substance that enters their body.

Although originally suspended by cycle sport's governing body, the Union Cycliste Internationale (UCI), pending an investigation, Contador was eventually cleared by the Spanish cycling federation (RFEC) and returned to racing in February. 

He has since won the 2011 Giro d'Italia, Vuelta a Murcia and Volta a Catalunya, and placed fifth overall at the Tour de France.

The CAS panel will study all of the supporting material put in front of them by the UCI and WADA on one side, and RFEC and Contador's defence team on the other to decide whether Contador should be suspended for the positive test.

If the suspension is back-dated to the time of the positive test in July 2010, Contador stands to lose all results obtained since then.

Here we present a timeline of the case, with links to relevant news articles.
