Hall & Oates are embroiled in a confidential legal battle that has led to Daryl Hall getting a restraining order against his former music partner John Oates.

Little information about the lawsuit is publicly available, as the court documents are sealed, but based on court records, Hall filed an undisclosed complaint against Oates on Nov. 16, as well as a motion for a temporary restraining order. The following day, the court officially issued a temporary restraining order to begin Nov. 30.

Hall disparaged Oates on Bill Maher’s “Club Random” podcast last year, saying, “You think John Oates is my partner? … He’s my business partner. He’s not my creative partner.”
