Hong Kong Basic Law Handbook continues to be the definitive work for anyone interested in understanding the operation of the Basic Law. A number of significant developments in constitutional law have taken place since the publication of the first edition in 2015. These include the interpretive power of the Standing Committee of the National People’s Congress under Article 158, the oath-taking requirement under Article 104, freedom of expression, the rights of prisoners, the ability of same-sex partners in civil relationships recognised in other jurisdictions to obtain a dependent visa, and more. Included are useful appendices on cases: (a) declaring legislation unconstitutional; (b) suspending declaration of unconstitutionality; and (c) cited from other jurisdictions.
