Pebe had alleged an “intentional and negligent infliction of emotional distress based on the alleged abuse" on Dr. Luke's part, after he had sued her for defamation in the ongoing legal battle, which started when Kesha claimed her longtime producer had sexually abused her and therefore wanted out of her contract with his record label.
The suit is just one of the several going on in New York, Los Angeles and Tennessee. Earlier this month, a judge dismissed Kesha's lawsuit against Sony in New York. In the meantime, Dr. Luke (a.k.a. Lukasz Gottwald) has had to "downsize" some departments at his Kemosabe Records label, handing off some responsibilities to parent Sony.
After announcing the project, Zedd took to Twitter to clarify that they had gotten permission from Dr. Luke, who thanked him publicly for the clarification.

We didn't use any loop holes. Kemosabe / RCA gave us permission to release this song!
