(I may be overlooking any number of things here; if I am, please let me know.)
Per Rule 879, quorum on these decisions was N-2, where N was the number of players who voted on the last proposal decision before they were initiated (not resolved). * They were initiated on July 15 * Last proposal decision resolved before that was 8057 on July 1 * Players voting on that decision were Murphy, Aris, V.J. Rada, twg, PSS, ATMunn, and possibly Trigon and Corona (either both effective or both ineffective) * V.J. Rada's loss of voting power didn't start till July 15 Thus, I believe the statement is FALSE; N was either 6 or 8, so quorum on 8066 et al was either 4 or 6.
