"There's no doubt he had a great season last year. But I'm sure that everything that needs to get done will get done," Cheika said. "But it's pretty important that I stay out of it and let it take its course."
Cheika said he spoke to Beale earlier this week, while ARU chief Bill Pulver admitted during his unveiling of the new Wallabies coach that the pair had discussed the backline ace during contract negotiations.
Cheika is privately very concerned about the ramifications of the Waratahs losing Beale should he be found guilty of misconduct and not be offered a new ARU contract.
Apart from that dreaded scenario leaving the Waratahs impossibly short of time to find a quality replacement ahead of their Super Rugby title defence commencing in February, Cheika fears losing Beale would also impact on the franchise's ability to recruit other stars.
Patston resigned earlier this month citing stress following the ordeal which triggered one of the most tumultuous fortnights in Australian rugby history.
The saga also claimed the scalp of coach Ewen McKenzie, who stood down after Saturday's Bledisloe Cup loss to New Zealand.
It is unclear whether McKenzie or Patston, due to no longer being employees of the ARU, will give evidence at tonight's hearing when Beale faces a charge of breaching section 7.3 of the ARU's Member Protection policy, which relates to anti-discrimination and harassment.
Even if Beale, who has a long rap sheet, is cleared of misconduct, Cheika said that didn't necessarily mean he'd be on the next plane to Europe for the Wallabies' showdowns with the Barbarians, Wales, France, Ireland and England on successive Saturdays in November.
"I wouldn't put it that way just yet," Cheika said. "You've got to just let it pan out."
