When RJD member and state minister Shivchander Ram stood up to answer questions on the Health department, the BJP members protested the absence of Yadav.
As part of the protest, three BJP members refused to ask questions related to the Health department.
Leader of Opposition in the Council Sushil Kumar Modi and senior minister Bijendra Prasad Yadav also had a heated exchange over the minister's absence from the House.
Former chief minister Rabri Devi attacked BJP for "unnecessarily" making an issue in the House.
"If the Health minister faces difficulty in answering questions, BJP will assist him," he said in a lighter vein.
