After announcing that her agency was causing a delay in her comeback late last year, singer Ivy has filed an official lawsuit against them. According to information revealed by the Seoul Central District Court on January 7th, Ivy filed a lawsuit against STOM E&F, and asked to terminate her contract. Through her manager, Ivy revealed, "I signed an exclusive three-year contract with the company back in 2009, but since then, they have decided my entertainment activities without any discussions with me, and have been neglecting my career.� They have yet to calculate the $20,000 USD I've earned in profit from my activities, and they've also failed to pay me the profits made from my third album, which was released October of 2009." She continued, "I've notified everyone that I terminated my account with the company as of June 21, 2010, but music industry representatives will not discuss any activities with me because my exclusive contract is still valid with STOM E&F.� I have filed a lawsuit in order to prove that the contract is invalid." This isn't the first time that STOM E&F celebrities have filed a lawsuit against the agency. Comedians MCs Yoo Jae Suk and�Kim Yong Man, as well as singer Yoon Jong Shin have all notified the company of their contract termination due to their failure in adequately paying their stars.
