In 2003, following a petition by the Centre for Public Interest Litigation (CPIL), the Supreme Court of India restrained the Central government from privatising Hindustan Petroleum and Bharat Petroleum without the approval of Parliament. As counsel for the CPIL, Rajinder Sachar and Prashant Bhushan said that the only way to disinvest in the companies would be to repeal or amend the Acts by which they were nationalised in the 1970s. As a result, the government would need a majority in both houses to push through any privatisation.[6]
