JYJ (previously known as JUNSU/JEJUNG/YUCHUN) is a trio, formed by former members of the South Korean boyband 동방신기 / 東方神起 (TVXQ) : Jaejoong (영웅재중/김재중), Yoochun (믹키유천), and Junsu (시아준수). The three members of TVXQ filed a lawsuit in mid-2009 against their South Korean record label, SM Entertainment, arguing that the 13-year length and structure of their exclusive contracts as well as the terms of profit distribution were unilaterally disadvantageous towards the artists and should be invalidated. The Seoul Central District Court in October, 2009 ruled in their favor on this matter.
