In 2008, following agitation against Biharis and other north Indians travelling to Maharashtra to take civil service examinations for the Indian Railways due to an overlimit of the quota in their home provinces, Thackeray also said of Bihari MPs that they were "spitting in the same plate from which they ate" when they criticised Mumbaikars and Maharashtrians. He wrote: "They are trying to add fuel to the fire that has been extinguished, by saying that Mumbaikars have rotten brains." He also criticised Chhath Puja, a holiday celebrated by Biharis and those from eastern Uttar Pradesh, which occurs on six days of the Hindu month of Kartik. He said that it was not a real holiday. This was reportedly a response to MPs from Bihar who had disrupted the proceedings of the Lok Sabha in protest to the attacks on North Indians. Bihar Chief Minister Nitish Kumar, upset with the remarks, called on the prime minister and the central government to intervene in the matter. A "Saamna" editorial prompted at least 16 MPs from Bihar and Uttar Pradesh, belonging to the Rashtriya Janata Dal, Janata Dal (United), Samajwadi Party and the Indian National Congress, to give notice for breach of privilege proceedings against Thackeray. After the matter was raised in the Lok Sabha, Speaker Somnath Chatterjee said: "If anybody has made any comment on our members' functioning in the conduct of business in the House, not only do we treat that with the contempt that it deserves, but also any action that may be necessary will be taken according to procedure and well established norms. Nobody will be spared.'"
