RIO DE JANEIRO, Aug. 31 (Xinhua) -- The International Federation of Association Football (FIFA) on Friday said that it will appeal against the decision taken by Brazil's Superior Court of Sports Justice (STJD) to acquit football club Botafogo and its striker Dodo over the player's doping offense.

FIFA's Director of Legal Division Marco Villiger and Deputy Secretary to the Disciplinary Committee Wilma Ritter faxed the Brazilian Football Confederation (CBF), stating that the international entity analyzed the case and decided to take it to the Court of Arbitration for Sports (CAS), headquartered in Lausanne, Switzerland.

According to CBF, FIFA was notified on the acquittal on Tuesday, 21 days after the decision was announced by the STJD. On Thursday, STJD President Rubens Approbato Machado said that the Court will resume the case in order to investigate the possibility of forgery in the evidences provided by Botafogo.

In July, tests held on caffeine capsules, which Dodo would take before each game, showed that they were contaminated with fenproporex, an appetite suppressor banned by the World Anti-doping Agency (WADA). STJD accepted the argument that the player and the club were not aware of the contamination, once the capsules were manufactured by an external lab.

The lab, which was threatened to be closed down, released its sales records to a local newspaper. According to the records, Botafogo sent more capsules to the tests than it had purchased from the lab, which aroused suspicion over authenticity of the evidences.
