Holzman and another nun - who is now the only remaining member of the Sisters of the Immaculate Heart of Mary - argued they had the right to sell the property, where they had lived since the 1970s until the Archdiocese evicted them in 2011.
Perry agreed to buy the property for $14.5m (£10.4m) in 2015, but the deal turned sour when the former residents objected. There apparently were 2 buyers who wanted the property badly - Katy and a restaurant owner named Dana Hollister.
In 2016, a judge ruled that the nuns' sale to Hollister was invalid, paving the way for Perry to purchase the property.
The sisters said they previously spoke with Archbishop Jose Gomez, who agreed they could choose who would purchase the property, but they could not get a hold of him once they made a decision to move forward with Hollister, The Los Angeles Times previously reported.
THE nun who was locked in a bitter court battle with Katy Perry has died in court - during the middle of a hearing.
ABC reported the sisters pooled their money together to buy the 8-acre property in 1972.
The case has been put on hold following the nun's death, although they had previously appealed to Pope Francis directly to give them their convent back. 'She had nothing to do with forcing herself on us'. According to the Associated Press, the Los Angeles archbishop had approved the star's bid, however official approval on the sale was yet to come through from The Vatican. In November of previous year, a jury found that Hollister had intentionally interfered with the sale to Perry and a judge ordered her to pay millions to the archdiocese and the singer.
Gomez added that he has offered a Mass for "the repose of her soul".
Because the sisters are required to seek permission from the Vatican before selling properties worth over $7.5 million, Katy and the Catholic Church were awarded nearly $10 million in damages, and the battle rolled on. They also disapproved of Perry's sometimes "revealing" outfits on stage.
