opportunity to comment on the suspected or alleged ineligibility. 3.2.2 Any comment so made may be recorded by the CTD, and subsequently may be presented at any Stewards’ Hearing Inquiry and/or to the Category Technical Panel. 3.2.3 Should the CTD fail to receive an adequate comment on the suspected or alleged ineligibility, which the CTD alone has sole discretion to consider as adequate or satisfactory, the CTD may require the Car to be impounded and examined, including such dismantling as may be necessary, to determine the points of eligibility in

question. 3.2.4 At the direction of the Stewards, any components or parts of a Car may be sealed by the CTD for examination by the Category Technical Panel or by the CTD. C 3.3 Disputes In the case of a dispute about a Car’s compliance with any of the provisions of Division C: 3.3.1 Any technical issue, including the eligibility, of Cars will be referred to the Stewards by the IPO CTD for determination 3.3.2 The Stewards will conduct an Hearing Inquiry into the issue and may make any

decision thereon. 3.3.3 If, during any such Hearing Inquiry, the Stewards determine that the matter is of a technically complex nature the Stewards may: 3.3.3.1 refer only the technical issue to the Category Technical Panel for a determination; 3.3.3.2 adjourn the Hearing Inquiry until the determination of the Category Technical Panel is received; and 3.3.3.3 subsequently resume and complete the Hearing Inquiry and make a decision taking into account the determination of the Category Technical Panel.

3.3.4 The determination of the Category Technical Panel will be unconditionally binding on any V8 Supercar National Court of Appeal hearing or Stewards’ Hearing Inquiry in regard to that issue. 3.3.5 Any dispute regarding the compliance of a Car with this Division C will be assessed, where appropriate, by the inspection of random samples of the relevant Family of a Vehicle. C 3.4 Minor Non-Compliance © AVESCO –2005 Division “C” Page C 5 3.4.1 The CTD, having noted an area of minor non-compliance, may endorse the Car’s

CAMS Log Book with an entry regarding rectification of the non-compliance. 3.4.2 Having so endorsed the Car’s CAMS Log Book, before the Car is permitted on to the race track, the CTD must send to the Stewards the Log Book and a note in the following form: "In my view, the minor non-compliance noted in the Log Book of this Car does not improve the performance to such an extent that the Car should be excluded from this Meeting, and thus it may compete in this condition for this Meeting only."

3.4.3 Upon receipt of the note referred to in Rule C 3.4.2, the Stewards may then permit the Car to participate in the Meeting subject to the endorsement being countersigned by the Stewards in the Car’s Log Book. 3.4.4 If the Stewards have specifically approved the participation of a Car notwithstanding an endorsement in its CAMS Log Book pursuant to Rule C 3.4.1, then no protest or complaint on that ground by any other person will be accepted in respect of that Meeting. © AVESCO –2005 Division “C”
