Kesha's attorneys are seeking to overturn a judge's decision to dismiss her efforts to void her recording contract.

The We R Who We R star is fighting to terminate her recording contract with Sony Music and its subsidiary, Kemosabe Records, which is owned by producer Dr. Luke, real name Lukasz Gottwald. Kesha has accused the hitmaker of subjecting her to years of sexual and emotional abuse.

She had her efforts shut down in a Big Apple court last month (Feb16), but her lawyers have now filed a motion to overturn the ruling. According to the New York Post, the 29-year-old's attorneys have equated the judge's decision to slavery.

"The Court's ruling requiring Kesha to work for Gottwald's companies, purportedly without his involvement... (forces her to work against her will)," attorney Mark Geragos writes. "As the Court itself recognised, 'It's slavery.' You can't do that."

Geragos also insists if Kesha continues to work under Dr. Luke it will cause serious damage to her career.

"Kesha submitted affidavits by individuals with over 100 years of collective personal experience in the music industry, each of whom attested to the fact that a young pop star's fame will fade quickly, and permanently, due to a loss of momentum," he continues.

It is unclear when the judge will rule on Kesha's motion.

Dr. Luke has strenuously denied all accusations against him. In a series of tweets last month (Feb16), he wrote: "I didn't rape Kesha and I have never had sex with her. Kesha and I were friends for many years and she was like my little sister."

Dr. Luke filed a countersuit against Kesha and her mum for defamation and extortion, alleging the mother-daughter duo threatened to go public with sexual assault claims unless he released her from the management contract the star, who is now 28 years old, signed with him when she was 18.

"Kesha and I made a lot of songs together and it was often good but there were creative differences at times," he added.
