National Security (Legislative Provisions) Bill 2003 (Chinese: 2003年國家安全(立法條文)條例草案) was a proposed bill which aimed to amend the Crimes Ordinance, the Official Secrets Ordinance and the Societies Ordinance pursuant to the obligation imposed by Article 23 of the Basic Law of the Hong Kong Special Administrative Region of the People's Republic of China and to provide for related, incidental and consequential amendments. The proposed bill caused considerable controversy in Hong Kong and a massive demonstration on 1 July 2003. In the aftermath, James Tien resigned from the Executive Council and the bill was withdrawn after it became clear that it would not get the necessary support from the Legislative Council for it to be passed. The bill was then shelved indefinitely.
