Totally agree with Whale and Jimmy’s posting.
As no agenda was provided to all the owners prior to any meeting, and no minutes of said meeting was again provide to all owners within the 7 days of the meeting, none of the decisions made were valid (these are required to enable owners to see what the EC are doing on their behalf and to keep the EC honest)
At the very least you should inform your SM NOT to accept any instructions from these 2 cowboys until the OC has decided what to do about recovering any illegal spending authorized by these 2.
Because the SM would not have been in the loop to receive EC agenda or minutes they most likely paid the bills on instructions from the 2 EC members not realizing that the procedures hadn’t been followed.
Maybe speak to the SM about recovering said money from the 2 members who illegally authorized it. I believe ANY owner would be entitled to do this if EC spends money without owners knowledge.
If they had sent out Agenda and minutes to all owners then the action of the 2 would have been legal. Do you have a SM or do you self manage.
