K-pop boy band B.A.P members filed a lawsuit against TS Entertainment on Thursday, demanding termination of their contracts, a local news outlet reported.

All six members of B.A.P -- Yongguk, Himchan, Daehyun, Youngjae, Jongup, Zelo -- submitted legal documents to the Seoul Western District Court on Wednesday to nullify the exclusive contracts that they had signed with the agency in March 2011.

The idols cited the unfair contract that only benefits the label as the reason behind their decision to sue the agency. They called the contract as “slave contract.”

They mainly took issue with the unreasonably long seven-year contract, invasion of privacy, exploitation of basic rights, and unjust distribution of profits from their work.

The group claimed that since their debut in January 2012, each member has brought back 18 million won home though they made about 10 billion won for their activities at the K-pop scene.

TS Entertainment has yet to announce its stance on the group’s legal action.
