The whereabouts programme is used by anti-doping organisations worldwide and requires athletes to regularly log details of their location so they can be located at any time for drug testing. Top level athletes involved in the programme need to specify a one-hour timeslot each day in which they will be available for drug testing.
Under the current rules, if they fail to correctly record their whereabouts or miss a test three times in the space of 18 months it is considered an anti-doping rule violation.
DFSNZ argued that Mr Gemmell had missed two tests and filed incorrect information on another occasion within an 18-month period. The New Zealand Sports Tribunal dismissed the case, saying the first missed test should not be counted because reasonable steps were not taken to locate Mr Gemmell, namely telephoning him to let him know that an official was at his nominated location to test him.
But the CAS did not agree with the tribunal and Steel was pleased to have the procedures outlined for both anti-doping organisations and athletes.
"A telephone call to notify an athlete that a doping control official is present gives those who dope the time and opportunity to alter the integrity of their sample if they so choose. This goes against the very purpose of surprise testing."
CAS noted the case was not one of "an athlete deliberately trying to avoid or circumvent the testing regime", and imposed a lesser ban than the maximum allowable of two years due to mitigating circumstances.
Gemmell's 15-month period of ineligibility is backdated from February 12, 2014.
