The Court of Arbitration for Sport has decided that Hungarian athletes Adrian Annus and Robert Fazekas must forfeit the Olympic gold medals they won in Athens because of doping offenses.

The CAS upheld a decision by the International Olympic Committee to strip them of their medals.  The International Association of Athletics Federations has also filed appeals with the CAS asking that the two Hungarians be banned for two years.

Fazekas was stripped of the discus gold medal after he refused to provide a urine sample in his post competition drug test. The CAS said Fazekas failed to provide any justification for his actions. The gold medal was awarded to Lithuania's Virgilijus Alekna.

Annus lost the medal in the weight hammer throw after the IOC said his samples indicated possible tampering.  Annus did pass two drug tests in Athens, but the Olympic Committee said that his samples appeared to belong to two separate athletes. The Hungarian had previously announced his retirement and Japan's Koji Murofushi was promoted to the gold medal.
