Britney Spears’ lawyer has taken Jamie Spears to task in the wake of new allegations of intrusive and possibly illegal surveillance.

Attorney Mathew Rosengart brought down the hammer in an L.A. County Superior Court filing Monday after the recent release of the FX/Hulu documentary “Controlling Britney Spears” and a report by the New York Times published in concert with the film.

“Mr. Spears was, of course, never fit to serve, for all of the many compelling reasons already contained in the record, ranging from his lack of financial acumen, to his bankruptcy, to his reported alcoholism, to the trauma he caused his daughter since childhood, to the Domestic Violence Restraining Order recently issued against him,” Rosengart wrote in a third supplement to a petition seeking removal of Jamie Spears as conservator of his daughter’s estate.

“But now, the chickens have truly come home to roost,” he continued. The New York Times “reported that Mr. Spears engaged in horrifying and unconscionable invasions of his adult daughter’s privacy. Specifically, the Times reported that he and others ‘ran an intense surveillance apparatus that monitored [Ms. Spears’] communications’ and also evidently captured attorney-client communications with her prior lawyer … a sacrosanct part of the legal system.”
