It is debatable whether he excelled as a lawyer, defending many eminent persons, including Sheikh Abdullah, the then Chief Minister of Jammu and Kashmir state, when he was arrested in 1958, or an academic scholar chronicling facts and paying attention to the details of the subject he was working on. He produced scholarly works and wrote books, including Savarkar and Hindutva (2002); The Babri Masjid Question 1528–2003: ‘A Matter of National Honour’, in two volumes (2003); Constitutional Questions and Citizens’ Rights (2006); The RSS and the BJP: A Division of Labour (2008); Jinnah and Tilak: Comrades in the Freedom Struggle (2010); Article 370: A Constitutional History of Jammu and Kashmir (2011); Islam, South Asia and the Cold War (2012); The Destruction of Hyderabad (2014). His last book, published by Tulika was Destruction of the Babri Masjid, A National Dishonour. He was a defender of the Constitutional principles, whether in Constitutional courts or through his writings. He wrote brilliant articles in The Frontline, Economic and Political Weekly, and other publications.
