While I think there could be grounds to challenge the interpretation of the meaning of the word “present”, I do not believe that such a challenge would result in any changes to the decisions undertaken at the AGM.
This is because an overwhelming majority of the Society participated in the decisions (~75%), and the outcomes therefore reflect the will of the Membership in general.
So, Ryan’s suggestion is a pragmatic one aimed at allowing us all to get on with executing the purposes of the Society (i.e. larping) without getting unnecessarily bogged down in pointless constitutional minutiae.
However, if 20% of the Membership feel strongly about this approach, they can call for an SGM. This is a large minority, and I would be happy to attend an SGM if that many members feel it is the right thing to do.
