The World Anti-Doping Agency (WADA) announced on Tuesday that it has referred both Nigeria and Venezuela to the Court of Arbitration for Sport (CAS) regarding their lack of compliance.

A WADA statement read, “two separate requests for arbitration with the Court of Arbitration for Sport” in the two cases last week. The two national agencies were sanctioned in November for failing to address what the Montreal-based doping watchdog called a number of “critical requirements” in their anti-doping programs.

Being non-compliant results in losing the right to host international events or fly the national flag at events.

Both countries protest the accusations and resultant sanctions. The sanctions are suspended pending the outcome of the CAS decisions and the potential impact on Nigeria and Venezuela.

Compliance is essential for clean international sport, WADA said.
