Kesha's lawyer is pleading with a New York judge to approve their request for a preliminary injunction to allow the singer to start work on a new album without producer Dr. Luke.

The pop star has been locked in litigation with Dr. Luke since last year (14), when she accused the producer of alleged sexual assault and battery, sexual harassment, gender violence, emotional abuse, and violation of California business practices over their 10-year collaboration. She also claimed Dr. Luke repeatedly drugged her and that his abuse caused her eating disorder, which forced her into rehab at the beginning of 2014.

She subsequently added Sony Music bosses to her lawsuit, alleging they supported his reported behavior by doing nothing to stop it. The producer's Kemosabe Records is a subsidiary of Sony.

Dr. Luke is countersuing Kesha for defamation, claiming she fabricated the allegations in a bid to get out of her Kemosabe contract, while Sony chiefs insist they have been "caught in the crossfire", blasting Kesha's actions as nothing but a "transparent and misguided attempt to renegotiate her contracts".

In September (15), Kesha's legal representatives called on the New York judge to grant the injunction and make a decision about whether or not she has enough evidence to push to end her recording contract with Dr. Luke.

The lawyers alleged that without the preliminary injunction, their client "can't work with music producers, publishers, or record labels to release new music" - because she's tied to Sony.

On Friday (30Oct15), Kesha's attorney Mark Geragos filed new court papers, revealing the singer had written to both defendants seeking permission to record a new album for Sony without the involvement of Dr. Luke or his label - but the proposal was snubbed, according to Billboard.com.

"The letters in response indicated both Sony and Dr. Luke believe the exclusivity clauses remain in effect, they will not agree to refrain from enforcement, and Sony specifically will not work with Kesha unless she agrees to work with Kemosabe and Dr. Luke's company, KMI," Geragos writes.

He continues, "Kesha now faces an abysmal decision: work with her alleged abuser... or idly and passively wait as her career tick-tocks away. She is precluded from working in perpetuity because the term of her contract can only be satisfied if she records three more albums. Kesha needs the Court's assistance."

Dr. Luke's lawyer, Christine Lepera, previously insisted Kesha only had herself to blame for the music ban.

A statement released to WENN at the time read: "If Kesha now regrets her career being mired in legal proceedings, it's entirely her making. It was Kesha who chose to file a lawsuit falsely alleging abuse to gain advantage in contract negotiations, and now she must accept the consequences of her improper actions.

"As long as she continues to stand by her false claims of abuse against Dr. Luke and remains in breach of her contracts, he will continue to protect his professional and personal reputation, as well as his contractual rights, in a court of law. He looks forward to obtaining judgments in his favor."
