Human rights protection is enshrined in the Basic Law and its Bill of Rights Ordinance (Cap.383). By virtue of the Bill of Rights Ordinance and Basic Law Article 39, the International Covenant on Civil and Political Rights (ICCPR) is put into effect in Hong Kong. Any local legislation that is inconsistent with the Basic Law can be set aside by the courts. This does not apply to national legislation that applies to Hong Kong, such as the National Security Law, even if it is inconsistent with the Bills of Rights Ordinance, ICCPR, or the Basic Law. Hong Kong is generally perceived to enjoy a moderate level of civil liberties.

The police has been occasionally accused of using heavy-handed tactics towards protestors and questions are asked towards the extensive powers of the police.

There are also comments regarding a lack of protection for labour rights.

This is occasionally used as a yardstick by commentators to judge whether the People's Republic of China has kept its end of the bargain of the "One Country, Two Systems" principle granted to the Hong Kong Special Administrative Region by its current mini-constitution, the Basic Law, under the Sino-British Joint Declaration.
