LOS ANGELES -- A jurisdictional issue delayed Monday's scheduled start of a trial focusing on whether Donald Sterling's estranged wife had the authority under terms of a family trust to unilaterally negotiate a $2 billion sale of the Los Angeles Clippers.
Lawyers for Donald Sterling moved late last week to shift the case to federal court due to alleged medical privacy violations.
Los Angeles Superior Court Judge Michael Levanas delayed the start of the trial while Donald Sterling's lawyers sought a decision from a federal judge on whether to take the case.
The motion was assigned to a U.S. District Court judge to consider and Levanas ordered parties to return to his court at 2:30 p.m. PDT. "It may very well be this is not going to be in my hands," Levanas said.
Shelly Sterling was present for the day's initial court session but her husband was not.
"Unfortunately the case is in procedural limbo," said her attorney, Pierce O'Donnell.
Shelly Sterling struck the deal to sell the Clippers to former Microsoft CEO Steve Ballmer after Donald Sterling's racist remarks to a girlfriend were publicized and the NBA moved to oust him as team owner.
A court must find that Shelly Sterling acted in accordance with the trust and that the deal still applies - even though the trust has since been revoked by Donald Sterling - for the sale to proceed.
Donald Sterling's attorneys say that his wife "blindsided" him and he submitted to examinations under false pretenses. They allege there was undue influence in the doctors' findings, and that the exams and letters regarding his mental capacity were defective and incomplete.
But Shelly Sterling's attorney said that Donald Sterling voluntarily went to take scans of his brain and there was no requirement to remind Donald Sterling, who is an attorney, or his legal team of the trust's conditions.
Last month, Shelly Sterling's lawyers alleged that Donald Sterling and his attorneys threatened her legal team and the doctors who assert that he is mentally incapacitated.
In May, Donald Sterling's attorney told CBS News the diagnosis of the 80-year-old being mentally incapacitated is a "vast overstatement" and that Sterling only has a "modest mental impairment" and is "slowing down."
Also at issue is the question of what happens to a deal that hasn't been closed when a trust is revoked. Donald Sterling revoked the trust on June 9 - weeks after Shelly Sterling negotiated the deal with Ballmer.
Shelly Sterling's attorneys also contend that finishing the deal is part of "winding down" the trust's affairs and that she has an obligation to close or Ballmer will sue.
Donald Sterling's attorneys argue that the probate court lacks jurisdiction and that winding down affairs refers to passive actions, not a sale that markedly changes the assets in the trust and its value.
On Sunday night, lawyers for Shelly Sterling and Ballmer filed an emergency brief in federal court opposing Donald Sterling's motion to remove the trial to federal jurisdiction. They argued that no federal issue has been raised by him and he waived his right to move the case when he participated in the probate case with numerous motions. They argued that Levanas should order the trial to go forward in probate court.
Whatever happens, timing is tight. NBA owners must approve what would be a record-breaking deal and are scheduled to meet July 15 to vote. The brief filed Sunday said any delay will deny Shelly Sterling the chance to close the deal with Ballmer "without ever having had an opportunity for a hearing on the matter."
July 15 is the same day Ballmer's offer is set to expire - and there is no deal without the judge's approval of the sale.
