This is all I could find.
The 140 rule went to a vote by the University president's of each school. The final vote was a tie, 6 league institutions in favor and 6 against. It came down the vote of the University of Alabama president. Bryant had previously told Dodd that he would convince the president to vote against the ruling. However, when the voting was held, Bryant did not make an appearance, the University of Alabama president voted in favor of the 140 rule. This was the final straw for Dodd and Georgia Tech. Immediately following the ruling, the Georgia Tech president took the podium and announced that Georgia Tech would be officially withdrawing from the league.
This is all I could find on the vote in 1983,
. So when talks began that the Jackets would rejoin the conference, both Mississippi schools would not support a vote to let the storied program back in. In 1983, Georgia Tech retired their independent status and joined the Atlantic Coast Conference.
Not sure who else voted no if those were the only ones.
