Mehta was elected to Bihar Legislative Assembly twice in 2015 and 2020 from Bihariganj Assembly constituency. This constituency is a part of Madhepura Lok Sabha constituency and veteran leader Sharad Yadav used to represent this region in Lok Sabha. In 2020, Mehta defeated daughter of Yadav, Subhashini Yadav with a fair margin to clinch the victory for the second time.[6] Mehta raised the issue of unfair prices of maize crop, at which the farmers of Madhepura region were forced to sell their surplus maize. He advocated fixation of fair price for the farmers in order to benefit them during surplus production of maize in his constituency. He also worked for reconstruction of Uda-Madhuban roadway, which was made during the tenure of legislator Singheswar Prasad Mehta between 1980-85.[7]
Mehta is also associated with Kushwaha Rajnaitik Vichar Manch, an organisation working for political rights of Koeri caste.[8]
Controversies
An audio clip of Mehta was aired in 2017, in which he was found involved in telephonic conversation with a person, who was alleging him of taking bribe in name of helping him get a government job. A complaint was also made by a person named Nandan Mehta against him in this regard.[9]
