A Massachusetts appeals court judge has blocked the auction, scheduled to start next week, of dozens of works of art owned by the Berkshire Museum.
The preliminary injunction issued Friday night followed an appeal earlier in the day by state Attorney General Maura Healey.
Superior Court Judge John Agostini this week denied a request from Healey and other plaintiffs to stop the sale.
"If these objects are sold, there likely will be little if any opportunity to get them back," the AG wrote. "There is no indication that the museum is in immediate financial crisis."
Appeals Court Associate Justice Joseph Trainor granted Healey's request, ruling "the balance of the risk of irreparable harm...weighs in favor of" the attorney general.
According to the court's electronic docket, the Berkshire Museum is prohibited from "selling, auctioning, or otherwise disposing of any of the artworks that have been listed for auction" until at least December 11, while the appeal is considered.
Museum officials have said the proceeds will stabilize its finances and fund a major renovation.
Earlier on Friday, the museum's lawyer, William F. Lee, issued a statement calling the attorney general's appeal "misguided."
"Continuing this litigation jeopardizes vital educational, cultural and economic resources in a struggling community, placing the special interests of a portion of the well-funded arts community over people, especially young people, really in need," the statement read.
