iwas not at the event so cannot comment on what did or did not happen, as for quoting the rules i usually find very few people actually know them.
below is the section on cancelling events.
19. CURTAILMENT OF EVENTS
19.1
National Championship events can only be abandoned by a majority vote of the Committee members
present, after consultation with the Race Director. Other Sanctioned events may be abandoned by the
Race Director in consultation with the Organisers.
19.2
At abandoned events, scores from any Rounds or Finals can only be used if all heats in the
respective Rounds or all Finals have been completed. The overall qualifying positions after the last
completed round at the time of abandonment, will count as final positions with the corresponding points
being counted towards the Championship, providing a minimum of two rounds have been completed.
Where Round-by-Round qualifying has been chosen the positions will be determined as per. rule 15.25.
19.3
At abandoned events where less than two rounds of qualifying have been completed, the event will
be declared null and void and no results declared. National events will not be re-scheduled and any
relevant championship qualification will be reduced accordingly (i.e. if there were 4 rounds to count from 6,
then one abandoned event would mean there are 3 rounds to count from 5, etc.).
Regional events can be rescheduled (subject to 6.5) at the discretion of the Regional Rep. If an event is
rescheduled to use a date not originally specified for any Class, then the number of events to count for the
Regional Championship in that Class will be reduced accordingly, to allow competitors to achieve the
minimum number of events using the original dates only.
If the normal Tie Deciding system of highest points does not achieve a result, then the highest Qualifying
position at the last event in the Series for the Class will be used to decide the tie.
As darren says there is little point having a reserve date if you are not going to use it, if there was any doubt that you could complete two rounds then the race director should have stopped the meeting before it even started, equally once two rounds are complete its a meeting and therefor scores for the series.
as for voting to cancel that only happens at nationals and voting is the committee only, at a regional it is the race directors decision after consultation with the organisors, the racers do not get a choice!, so i am not sure why any voting took place.
bottom line is it is up to the race director to race or not because if it all goes horribly wrong he is carrying the can or the lawsuit.
