Stars management is believed to have failed to respond to Cricket Australia's code of conduct charge and call for the leg-spinning champion to attend a tribunal hearing on Monday in Melbourne.
Warne was hit with a Code 5 charge for bringing the Big Bash League into disrepute in his side's gut-wrenching last-ball loss to the Perth Scorchers at the WACA Ground on Wednesday ngiht.
Warne was charged as Stars captain for his second offence of slow over-rate in this summer's tournament.
He has been instructed by national game authorities to attend Monday's hearing in person.
But by close of business at 5pm (EDT) on Friday it is believed that the Stars' only response was a text message declaring that Warne would not be in attendance at the hearing.
Warne is understood to have already told his Stars teammates that he will not play again in the annual Big Bash series, after two years with the high-profile Melbourne franchise.
It is believed that Monday's hearing from Cricket Australia offices in Melbourne and coordinated by a chairman from teleconference in Perth, will go ahead whether Warne attends or not.
The legendary spin champion faces an automatic one-game ban and potentially more, as well as a heavy cash fine for his over-rate breach.
Warne is also certain to be hit with misconduct charges following his decision to claim in Perth on Wednesday night he was not his side's official captain.
His failure to communicate with cricket authorities on Friday, as well as poor communications from his team management could also add to any sanction.
