Mumbai, Oct. 18 -- US-born actor Imran Khan on Saturday filed a petition before the Bombay high court challenging the leave India notice (LIN) issued by the Foreigners Regional Registration Office (FRRO) in Mumbai, calling it arbitrary and issued in haste. The petition comes two days after the FRRO ordered him to leave the country by October 28 for demanding Chief Election Commissioner Gyanesh Kumar's ouster during a demonstration in the city on October 10. The petition is likely to be mentioned for urgent hearing on Monday before a bench of chief justice Mahesh Chandra Tripathi and justice Advait Sethna. In his petition, filed through MZM Legal, the 43-year-old actor contended that he had not breached any provision of the Immigration and Foreigners Act, 2025 or the Citizenship Act, which governs his rights and duties as an Overseas Citizen of India (OCI) and neither does the notice cite any specific breach. "The petitioner has resided peacefully in India since the age of two, has deep-rooted familial, marital, educational and professional ties to the country, and has no criminal antecedents," his plea stated. "By disregarding these material facts, the LIN reflects non-application of mind and the arbitrary targeting of the petitioner as a public figure." On October 10, police detained the actor and several other protesters, at the August Kranti Maidan after they joined activist Tushar Gandhi (Mahatma Gandhi's great grandson) in supporting the Cockroach Janta Party's (CJP) New Delhi-led campaign for the CEC's resignation. After police rounded up hundreds of protesters, BJP leader Kirit Somaiya sought action against Khan for participating in a political activity despite being a foreign national which led the FRRO to issue the LIN to Khan on October 15. The plea called the LIN "ex-facie arbitrary, illegal, unconstitutional and legally unsustainable", urging the court to strike it down. The actor has also invoked provisions of the Citizenship Act related to OCI cardholders supporting his claims, arguing that an OCI cardholder is not an ordinary foreigner and belongs to a different statutory class. He said the only allegation against him was a brief presence near the site from which he was turned away immediately after the police told him that the ground was closed. Meanwhile, shortly after filing the petition, Khan received a show cause notice from FRRO, asking him why his OCI registration should not be cancelled. "Not only is the show cause notice contradictory to the same FRRO's previous LIN, it just appears to be an attempt to correct the legal infirmity previously committed," MZM Legal said in a press statement....
