PRS Legislative Research's Chakhu Roy explained that defecting AAP MPs, including Raghav Chadha, may not be disqualified from Rajya Sabha. Roy reminded that ex-Chairman Venkaiah Naidu had approved merger of 2/3rd of TDP members with BJP. Former Lok Sabha secretary general PDT Achary said the Chairman's decision to either approve the merger or disqualify them could be challenged in court.
