A delegation of BSP leaders met Governor B L Joshi and handed him a memorandum, stating that the move was in violation of High Court and Supreme Court orders.
"The use of land in Dalit memorials for marriage and other events is in violation of High Court and Supreme Court's order, which means state government is deliberately doing it.
"It has no right to continue and we have demanded from the Governor to impose President's rule in the state,"BSP National General Secretary Satish Chandra Mishra told reporters.
The Samajwadi Party government had recently allowed holding marriage ceremonies and other events at various Dalit memorials in the state, claiming that the land there was "unutilised".
