After the devastating result of her court case last month, Kesha has filed an appeal to overturn the ruling on her contract.
The songstress pleaded for a temporary break from working with Dr Luke – who she claims raped her – but the judge ruled that she has to remain in her contract with Sony.
Yesterday, Kesha went to court in Manhattan with her lawyer to overturn the case, E! News has reported.
In the documents , Kesha's lawyer claims that forcing the singer to work with Dr Luke is akin to "slavery."
"First, the Court erred in basing its decision on its finding that Kesha could record without interference from Gottwald [Dr Luke]," the paperwork states.
"Although it recognised that "slavery was done away with a long time ago" and that 'you 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 recognised, 'It's slavery. You can't do that'."
But Dr Luke's lawyer has already responded saying that Kesha's allegations are "false."
