The Cossijurah case from 1779-1780 highlighted conflicts between the Supreme Court and the Supreme Council in Bengal. A zamindar named Raja Sundernarain owed a debt but avoided paying. When the Supreme Court issued a writ for his arrest, the Council protected the Raja and arrested the sheriff. This caused a power struggle over jurisdiction and authority between the two bodies. The case increased tensions and helped lead to reforms that clarified their powers through an Act of Parliament in 1781.
