Challenge Bathurst organisers intend to appeal a decision from the Confederation of Australian Motor Sport which effectively bans GT3 cars from competing at its event.

The Mount Panorama sprint meeting, held in November, is seen as an unofficial test for Bathurst 12 Hour teams, attracting several GT3 crews aiming to accrue valuable track miles ahead of the February showpiece.

However, this is now under threat following a decision by the Australia’s motorsport governing body to reclassify FIA GT3 cars.

Effective immediately, these cars are now only eligible to compete in the Bathurst 12 Hour and Australian GT Championship events in Australia.

The directive issued last month reads: “National Championships are sanctioned by CAMS to encourage, develop and recognise professional competition and provide a place or pathway for similar racing cars to compete fairly.

“Similarly Club Level, or grass roots competition is to provide a pathway for entry to the sport and for those who wish to compete in events where the focus is more on participation and enjoyment of the sport and not necessarily with a single desire to be performing at the highest levels of the sport.

“Therefore, CAMS must restrict certain vehicles from racing in certain events. In order to apply such a restriction, CAMS will be re-classifying applicable 2GT vehicles to a revised CAMS Category Classification code of 2GT CHAMP.

“For clarity, CAMS will only permit a vehicle defined by CAMS as a 2GT (FIA/ASN Homologation GT) CHAMP Log Booked vehicle eligible to compete in the Australian GT Championship, and other Australian GT permitted events.

“Accordingly, these 2GT CHAMP vehicles will not be eligible for any other competition. All other CAMS Classified 2GT vehicles will remain eligible for other competition events, whereby they are accepted for competition at such events.

“Included with this communication is a document detailing the CAMS 2GT CHAMP classification and a defining list of vehicles that will be classified as 2GT CHAMP regardless of the existing classification applied in a CAMS Vehicle Log Book.

“CAMS will be working with Australian GT, CAMS stakeholders and relevant competitors to update each CAMS Vehicle Log Book as appropriate. This will be undertaken during relevant Australian GT events and where necessary with direct communication with Log Book holders.”

The decision has sparked Challenge Bathurst event director James O’Brien to fight the ban.

“The recent statements by CAMS, issued on 24 May and 5 June 2017 respectively, aim to restrict certain FIA homologated GT3 automobiles (2GT) from competing at any CAMS sanctioned events other than Australian GT Championship or other Australian GT permitted events,” read a statement from O’Brien.

“CAMS intend to achieve these restrictions by re-classifying applicable 2GT automobiles to a code of 2GT CHAMP. CAMS have produced a list of automobiles to be re-classified as 2GT CHAMP, all of which would be ineligible to compete at the Event.

“We have reviewed the CAMS eligibility restrictions in conjunction with the International Sporting Code, CAMS Constitution and the National Competition Rules. It is our opinion that CAMS does not have jurisdiction to make a rule that restricts the participation of FIA homologated GT3 vehicles at the Event and consequently the vehicle eligibility restrictions which were announced on 24 May and 5 June 2017 are void.”

“The draft Supplementary Regulations (“the Regulations”) for the 2017 Event were submitted to CAMS for comment in late April. The final Supplementary Regulations were submitted to CAMS for approval on 26 June 2017.

“These Regulations include the eligibility of all FIA GT3 automobiles, as approved by CAMS at the 2016 Event, regardless of any domestic re-classification by CAMS. On 28 June 2017, CAMS refused to approve the Regulations without the restrictions above.

“We intend to appeal this decision through the Australian Motor Sport Appeal Court however are unable to provide a date for this Appeal.

“The date for entries to open in the Supplementary Regulations was 3 July 2017. Without approval of the Supplementary Regulations by CAMS, we are unable to accept entries to the Event.

“Once the Appeal has been heard, we will be able to advise the outcome and a revised date for entries to open.”

CAMS CEO Eugene Arocca says his organisation is prepared to deal with O’Brien’s appeal.

He admits the new directive is unlikely to be received positively by all competitors, but backs the call he believes is for the good of GT racing in the country.

“Inevitably there are going to be individuals whether they are vehicle owners or organisers that may not understand, accept or like that directive, but we always fall back on the responsibility we have for the sport,” Arocca told Speedcafe.com.

“We have been in discussions with James (O’Brien) and we confirmed yesterday that he would not be able to permit GT3 under the regulations in his event.

“Like anything there is always two sides to a story. If James feels aggrieved and wants to take this further then we will obviously deal with that when and if it arrives.

“We take our responsibility very seriously and we look at the sport as a whole.

“I feel sorry for those people that thought this was the position (that they would be able to race GT cars at State level) and then told it has been changed, but rules often change in sports on a regular basis.

“All I can say to those people is we made the decision based on the information we have and believe is right for the sport.”
