Aman Lekhi was appointed as an
Additional Solicitor General of India in the Supreme Court in February 2018. Since his appointment, his arguments have aided the Supreme Court in clarifying the law concerning the Narcotics Drugs and Psychotropic Substances Act, 1985. The Supreme Court accepted his arguments that in determining the punishment under the legislation, the deciding factor would be the quantity and not the purity of the narcotic drug. Additionally, his arguments were also accepted by the Supreme Court to expand the scope of the
Prevention of Corruption Act, 1988 for it to apply to deemed universities, which is seen as a departure from the
plain meaning rule of interpreting criminal law. Lekhi also appeared for the
Central Bureau of Investigation before the Supreme Court on their plea to investigate the sacrilege cases in Punjab. Lekhi represented the Central Bureau of Investigation to oppose the bail granted to
Upendra Rai. He is also currently assisting the Supreme Court in a Public Interest Litigation concerning the reforms of prisons in India. As Additional Solicitor General, Lekhi has appeared before the
Armed Forces Tribunal to defend the challenge to the appointment of the
Chief of Naval Staff (India), filed by Vice-Admiral
Bimal Verma. The Armed Forces Tribunal dismissed the plea while agreeing that the Government of India was justified in superseding Verma. He has represented the
Enforcement Directorate in the cases relating to the
2013 Indian helicopter bribery scandal, where he was successful in getting the dismissal of the anticipatory bail plea filed by
Ratul Puri and the bail plea of Deepak Talwar. Lekhi was also the Senior Advocate for the Maharashtra Police in the plea challenging the arrest of the journalist -
Gautam Navlakha. He has represented the Delhi Police in the case related to the assault of the Chief Secretary of Delhi and represented the Special Investigation Team in the 1984 anti-Sikh riots case. Lekhi was the counsel for the Government of Uttar Pradesh in the alleged "hate speech" case against Chief Minister
Yogi Adityanath, successfully arguing for the plea challenging the order of the Allahabad High Court dismissed. He represented the administration of the
Jawaharlal Nehru University when the students blocked access into the varsity's administrative building. Lekhi represented the Lieutenant Governor of Pudducherry,
Kiran Bedi in the appeal to the petition moved by a Congress MLA K Lakshminarayan challenging the communications issued by the Ministry of Home Affairs vesting powers with the Lieutenant Governor. In a major success for the Central Government, the appeal was allowed clearing the Lieutenant Governor to administer the day-to-day functioning of the Union Territory. He was engaged by the Department of Customs in the proceedings against the wife of
All India Trinamool Congress Member of Parliament
Abhishek Banerjee, Rujira Naroola for obstructing officers from checking her baggage at the Kolkata Airport. Lekhi successfully defended the ordinance banning the sale and import of e-cigarettes in India before the
