The 24-year-old World Champion and three team-mates had tested positive for the banned diuretic fur-osemide in May but their national governing body (CBDA) decided against banning them.
Swimming's world governing body FINA appealed that decision to CAS, who dismissed the appeal following a hearing in Shanghai. “The CAS Panel composed of Alan Sullivan QC, Olivier Carrard and Jeffrey Benz decided to dismiss the appeals filed by FINA against Cesar Cielo, Henrique Barbosa and Nicolas Dos Santos and to confirm the CBDA's decision concerning them,” CAS said in a statement.
FINA had asked for three-month suspensions to be imposed on Cielo, Santos and Barbosa and for one year against Vinicius Waked, who had been banned previously.
