"The ongoing uncertainty and secrecy of this process continues to do unprecedented damage to the reputation of the game and has placed unacceptable distress on players and their families.
"In every Australian team there are players and staff whose livelihoods and wellbeing have been compromised through this protracted process."
It is unknown whether the special General Meeting could see a spill of the ARU board and under-fire directors such Bill Pulver and Cameron Clyne turfed out.
RUPA, who have consistently backed the retention of five teams, said if it was made clear there was no way to cut a team and make the savings that the ARU have justified the cull on, they should withdraw from the 15-team model.
"If there is no clear way forward for Australian Rugby that provides the necessary cost savings to justify altering our current professional Rugby footprint in the middle of this broadcast cycle, then it's about time we stopped uppercutting ourselves, backed the retention of five Super Rugby teams and got on with fighting our common enemies outside the tent," Xenos said.
Amid reports the ARU are negotiating with Melbourne Rebels owner Andrew Cox about buying his licence back and shutting the franchise down, Xenos said that option didn't line up with the ARU's narrative about the financial problems the game is facing.
"Axing an Australian team and disenfranchising a Rugby community was justified five weeks ago by the ARU based on financial savings," Xenos said.
"Now, anywhere between six to ten million dollars promised to be invested into the game, including at the grassroots level, could be burned so that the ARU can cull a team and save face around the SANZAAR table.
"Why are we are cutting a team at all and limiting Australian Rugby's future if there are such discretionary funds within the game that ARU can afford to buy a license, only to scrunch it up and throw it away?"
