Lawyers for Kesha have said that the court hearing for her long-running defamation legal battle with producer Dr Luke – currently scheduled for next February – can’t go ahead until the New York Court Of Appeal has ruled on some side disputes. And, they claim, Luke’s legal team are responsible for delays in the appeals court making it less likely that those matters will be addressed before next February.Luke’s defamation lawsuit against Kesha is all that remains of a long running dispute between the former collaborators, which began when Kesha accused Luke of rape.
