LOS ANGELES (Reuters) – An attorney for Britney Spears on Monday stepped up demands for the swift suspension of the singer’s father from his role as her guardian, saying he had “crossed unfathomable lines” by reportedly bugging her phone and bedroom.

Mathew Rosegart filed a court document ahead of Wednesday’s hearing. He stated that the Friday television documentary “deeply concerning allegations” made it necessary to immediately suspend Spears.

A former employee of the security company Jamie Spears hired to monitor Britney Spears’ phone calls and texts, according to the New York Times documentary Controlling Britney Spears. The employee claimed that a listening device had been placed in the bedroom of her daughter.

Jamie Spears lawyers didn’t discuss the specific accusations, but stated last week that his actions were in his power as conservator. They “were made with Britney, Britney’s court-appointed lawyer and/or her consent.”

Jamie Spears is the father of his daughter since 2008. After she had a severe mental breakdown, he established a conservatorship to manage her business affairs. She has been under the conservatorship for her financial, personal and medical affairs.

To end her conservatorship, “Stronger,” she increased her efforts to do so in June. Jamie Spears made a surprising statement in September that he supports ending conservatorship, but said that there was no reason to suspend him.

Los Angeles Superior Court will hold a hearing in the matter on Wednesday.

Rosengart filed Monday’s statement stating that Rosengart should suspend Rosengart on September 29 and then terminate the conservatorship promptly.
