These rules will be absolute until changes have been passed by the Stock Hatch Steering Committee. It is envisaged that rule changes will only take place at the end of a racing season and will be available in good time for winter build projects.
These Rules and Regulations have been drawn up from the original Stock Hatch rules, taking into account any input from drivers and scrutineers so as to give every Stock Hatch driver within NASA an equal chance wherever they may race at and whoever they may race against.
Any Stock Hatch car not complying with these Rules and Regulations will race in its standard NASA Class. Drivers will be expected to maintain their cars in a tidy and presentable condition. Cars arriving at Scrutineering with obvious body damage will be turned away.
It is accepted that these rules may need amending or defining, however it should be noted that the principal of no modification remains absolute. Drivers are welcome to ask the Stock Hatch Steering Committee for a change or definition of the rules. Details of any such changes or definitions will be made available to all Stock Hatch drivers.
Any car attempting to defeat the spirit of the Class will be deemed illegal. If you are in any doubt at all, please ask first.. we would rather spend a few minutes on the phone that have to fail you.
"SHSC" refers to the Stock Hatch Steering Committee
New or amended 2017 rules are in bold
1) Cars must be front wheel driver, hatchback vehicles with the engine capacity between 1131 and 1600cc with only two valves per cylinder.

Same Make / Model TRIAL for 2016
1) For 2016, you are permitted to use any component from the same manufacturer of the vehicle you are using. For example, any Vauxhaull component may be used in any Vauxhaull shell. No modifications are permitted to allow the fitting of any of these components, however the geometry of the vehicle must not be altered. The caster camber, wheel base etc must follow the rules as described below or in the NASA class rulebook. This does not apply to the engine / gearbox / ECU.
1) All cars should have engines and ECUs sealed for the start of the season. Please contact the SHSC if you have any problems in getting your car sealed.

1) It is recognised that incidents giving rise to potential disciplinary proceedings may be reported in a number of ways, including reports from the Stock Hatch Steering Committee or from NASA Officials. Complaints from individual members or members of the public should be submitted in writing to the Secretary. Such individual complaints will investigated, but if it is found that the complaint was frivolous or malicious in nature, action may be taken against the person making the complaint. NASA will take no action arising from the anonymous communications; neither are the Stock Hatch Steering Committee expected to do so.
2) Only the NASA Board of Directors, at a disciplinary hearing can remove a members' licence to prevent nationwide racing. Clubs; Leagues and the Stock Hatch Steering Committee have the ability to impose a local ban regarding attending their specific meetings.
3) If a complaint is received by the NASA Board of Directors that indicates that there may be grounds for disciplinary action, the Board will act as follows:
a) One or more Directors will carry out an initial investigation to ascertain whether there is sufficient evidence of a disciplinary offence to justify formal proceedings, and will report findings to the Board.
b) The Directors(s) carring out this investigation will have the discretion to withdraw the accused person's licence or place other restrictions on the accused person while the investigation is in progress.
c) If, on the completion of the initial investigation it is considered by the Board that there are insufficient grounds for formal disciplinary action, all parties concerned will be notified in writing.
d) If the Board considers that formal disciplinary action is required, the case will; by default, be referred for action to the Club or League within those jurisdiction the alleged offence took place, and that Club or League will be expected to carry out disciplinary proceedings in accordance with 5) below.
e) If it is considered that the alleged offence is not appropriate to be dealt with by a Club or League, the case will be dealt with by the board in accordance with 6) below.
4) If a senior NASA Official witnesses and act of actual violence or a serious threat of violence or severe and aggressive abuse at a race meeting, or is satisfied that such an act has taken place, then any of these specific officials may immediately suspend the licence of the offender(s). They will subsequently report the facts of the incident to the NASA Secretary for a formal investigation to begin.
5) Disciplinary proceedings to be followed by Clubs and Leagues and Stock Hatch Steering Committee: The NASA Board will support Clubs and Leagues in their attempts to enforce a reasonable level of conduct and discipline at their race meetings. However, it is unable to do this and for them to be able to extend, with fairness, local penalties into Nationwide penalties then Clubs; Leagues and the Stock Hatch Steering Committee must follow a correct procedure.
a) Clubs; Leagues and the Stock Hatch Steering Committee must follow procedures laid down in their internal rules, constitution or by-laws.
b) Notwithstanding a) above, any disciplinary proceedings must comply with the following guidelines:
i) Do not allow anybody to sit on a disciplinary committee who has a vested interest or may be biased for any reason.
ii) Be clear about the nature of the complaint against the the accused person.
iii) Have the facts written down correctly and accurately.
iv) Obtain witness statements to support the allegations.
v) Invite a written statement from the accused person, and from any witnesses identified by the accused person.
vi) Conduct a formal disciplinary hearing as soon as possible after the incident. The accused person and / or their chosen representative should have the right to attend this hearing.
vii) Where penalties are imposed at a local level, they should be consistent with the national "Disciplinary Tariffs" outlined within the members handbook.
viii) The decision of the hearing should be communicated clearly in writing to the accused person.
ix) The accused person has the right to appeal against the decision and should be allowed 14 days to do so.
x) If they appeal, consider their fresh argument with an open mind. It is recommended that appeals should be heard by a different panel to the original hearing.
d) The Club; League or Stock Hatch Steering Committee, having followed this procedure request additional action from NASA. They have seven days after the expiry of the initial appear period to notify NASA of this request. The request for further action is to be in writing, supported by copies of all relevant documentation, and sent to the NASA Secretary.
6) Approved Championships / Series' will have the right to implement their own disciplinary procedures. In this case:
a) The jurisdiction of the Championship / Series will only extend to dealing with the disciplinary offences that have taken place at events forming part of that Championship / Series or peripheral activities organised by the Championship / Series.
b) The disciplinary procedures of the Championship / Series must be documented in the Championship / Series Regulations and will apply to all competitors who, by entry in to an event forming part of that Championship / Series, will be deemed to have signed their agreement to these regulations.
c) These procedures will be expected to follow the guidelines laid down for the Clubs and Leagues to follow.
d) Any penalties imposed by the Championship / Series will be enforceable at events forming part of that Championship / Series and may be extended to other events specified in the Championship / Series Regulations.
e) The Championship / Series will have the same rights as a Club or League to refer series disciplinary cases to the NASA Board for consideration of further action.
7) It is entirely up to the local League / Club and / or NASA whether a person may continue to race, officiate or attend events in any capacity, while a disciplinary hearing is awaited or an appeal is taking place.
