Kesha has filed an appeal against the New York Supreme Court ruling last month, that dismissed her request for a preliminary injunction, that would allow her to record music outside of working with producer Dr Luke (real name Lukasz Gottwald). The singer has previously accused her longtime collaborator of drugging and raping her. Luke has also countersued for breach of contract and defamation, while denying the allegations.

Kesha Kesha has filled an appeal over last month’s court ruling in her case against Dr. Luke.

The documents, filled by Kesha’s legal team and obtained by People read: "The court erred in basing its decision on its finding that Kesha could record without interference from Gottwald.” They go on to compare Kesha’s contract with the producer to slavery.

“Although it recognized that 'slavery was done away with a long time ago' and that '[y]ou can't can't force someone to work ... in a situation in which they don't want to work,' the Court's ruling requiring Kesha to work for Gottwald's companies, purportedly without his involvement, does just that As the Court itself recognized, '[i]t's slavery. You can't do that,” the statement continues.

When the ruling was delivered last month by Justice Shirley Kornreich it was said that Kesha was already free to record music without the involvement of Dr Luke and would not need to be in direct contact with the producer.

In response to the appeal Luke's attorney, Christine Lepera, released a statement saying: "The Court repeatedly stated Kesha was already free to record without Dr. Luke, and that she had not presented any facts supporting her claims.”

“That's because all the evidence – including Kesha’s own sworn testimony – show her allegations are false. Her attorneys can continue manufacturing even more false and outrageous claims, but the fact remains that her time would be better spent in a studio than wasting time having her lawyer and mother spin lies in the media."
