SMISA voting rules can be quite fluid and change to suit the situation when it suits them
eg, Last year Xmas meal failed to get picked in 3 monthly, soon arranged an online vote to sanction a donation, which was passed.
A 3 monthly vote was considered good enough to sanction ring fenced fund to be breached (Debatable)
As posted earlier Section 105 may facilitate a new procedure or change but may or may not need ratified by members.
If SMISA wants SMISA gets.
