Jarrod Bannister with Commonwealth Games gold medalAugust 9 - Australia's Commonwealth Games javelin champion Jarrod Bannister will not be able to defend his title in Glasgow next year after being banned for 20 months for missing a series of anti-doping tests it was confirmed here today.

The 28-year-old from Townsville in Queensland had revealed on his Facebook page that an appeal to the Court of Arbitration for Sport (CAS) had been unsuccessful.

The decision has now been confirmed by Athletics Australia officials here, preparing for the International Association of Athletics Federations (IAAF) World Championships, which is due to start tomorrow.

Bannister had been charged by the Australian Sports Anti-Doping Authority (ASADA) for an offence under article 6.4 of the Athletics Australia Anti-Doping Policy concerning his availability for out-of-competition testing.

Bannister subsequently admitted to an Athlete Whereabouts Violation after missing out-of-competition testing on three occasions within an 18-month period.

The CAS found however that with regard to the third of those missed tests there was no deliberate attempt by Bannister to avoid it, and subsequently determined that a ban shorter than the maximum possible sanction of two years was appropriate.

The CAS has determined that Bannister's suspension should run from June 19, 2013, through until February 18, 2015.

"Within the court reasons , it was found that there was no deliberate action by myself to avoid being tested, that finding is consistent with my defence submissions at the hearing on the 21 June 2013," said Bannister, who won the Commonwealth Games javelin at New Delhi with a throw of 81.71 metres.

"I respect the award issued by Mr Alan Sullivan SC , naturally I am still deeply disappointed at receiving the period of ineligibility," Bannister wrote on Facebook.

Bannister urged other athletes to be "vigilant when dealing with Athletics Australia and ASADA" when giving whereabouts information, to check room lists daily when being accommodated by Athletics Australia and to maintain written correspondence with the national body rather than relying on verbal approval.

Dallas O'Brien, chief executive of Athletics Australia defended their procedures and claimed it was down to the athlete to ensure that they were available for out-of-competition testing.

"Athletics Australia is a signatory to the WADA (World Anti-Doping Agency) Code because we are committed to ensuring that those athletes who breach our anti-doping policy are dealt with in the manner appropriate to the circumstances of their case and any violation with which they should be charged," he said.

"For that reason it's vitally important that all Australian athletes understand the range of obligations they have under the WADA code and strictly adhere to them.

"That includes ensuring that the details of their whereabouts are always updated so that out of competition testing can be conducted by the IAAF, ASADA or WADA.

"Alongside their counterparts in a small number of other Olympic sports, our high-end participants are particularly obligated to be meticulous about their compliance with the whereabouts aspects of the sport's policies - especially given the frequency of out-of-competition testing through the extensive programs of ASADA, WADA and the IAAF which may make them more likely to be accountable in this area than athletes in other sports.

"We are disappointed that Jarrod did not meet his obligations as one of our top performing athletes and this case demonstrates the need for all athletes to be diligent and responsible.

"Part of this is that it is the individual athlete's responsibility to notify the World Anti-Doping Agency of all international travel arrangements and precise accommodation arrangements.

"We acknowledge this can be challenging once the athlete is already overseas and perhaps we need to look at how we can do a little more to assist the athletes in those circumstances to fulfil their requirements.

"Athletics Australia will reinforce to its athletes the message that this decision brings and at the same time provide additional education and assistance in order to maximise compliance with the sport's strict and wide ranging anti-doping policy."
