Soon after the House met, three new members -- Congress members from Rajasthan Karan Singh Yadav and Raghu Sharma as well as TMC member from West Bengal Sajda Ahmed -- took oath.
Mr Yadav has been elected from Alwar while Mr Sharma and Mr Ahmed represent Ajmer and Uluberia constituencies, respectively.
After the members took oath, Speaker Sumitra Mahajan made the obituary reference about Hukum Singh, who represented the Kairana constituency in Uttar Pradesh.
79-year-old Singh was also the chairperson of the Standing Committee on Water Resources and a member of the General Purposes Committee of the Lok Sabha.
The House stood in silence for a brief while as a mark of respect for the departed soul before proceedings were adjourned.
