While Gemmell's failures for which he had been sanctioned all occurred within an 18-month period, they fell outside a 12-month period.
Therefore, if his failures had occurred within the same relative time frame but after January 1, 2015, he would not have committed a whereabouts anti-doping violation.
The tribunal felt it had jurisdiction under the relevant rule to decide the application and decided a reduction in the suspension was appropriate.
The tribunal noted that while today Gemmell's conduct would not result in a whereabouts violation, he had been found to have committed an anti-doping violation of the whereabouts rule as it existed at the time.
The tribunal stated: "What the tribunal has to decide is whether it is appropriate to modify the sanction which CAS saw fit to impose for that violation on the basis that the WADA sporting community has decided that the earlier rule was too onerous. An athlete today who replicated Gemmell's circumstances would commit no violation and face no sanction."
In the tribunal's view the fact that the WADA sporting community has decided the rule under which Gemmell is presently subject to a 15-month period of ineligibility was too onerous does justify some reduction in that period of ineligibility.
Gemmell's period of ineligibility commenced on February 12, 2014. The tribunal is satisfied that with the overlay of the DFSNZ appeal to CAS that Gemmell has suffered detriment in pursuing career opportunities since the date the violation charges were laid. He has also suffered the stress, publicity and cost consequences of three hearings. As the tribunal has noted the fact of a violation remains.
Weighing all the factors, the tribunal decided it was appropriate to reduce the suspension to a 12-month period equivalent to the minimum period that could have been imposed under the old rules and ordered Gemmell's suspension to expire at midnight on February 12, 2015.
Kiwi golfer Ben Campbell told the Herald last week that Gemmell would caddy for him during a series of tournaments throughout Australasia during the next two months. Gemmell first caddied for Campbell at the New Zealand Open in 2011.
