Hong Kong's national security law (NSL), introduced in 2020, has sparked ongoing concerns about civil liberties in the city. The law was enacted by China following the 2019 protests and criminalises secession, subversion, terrorism, and collusion with foreign forces. Critics argue it has created a climate of fear and eroded the autonomy promised under the 'one country, two systems' principle.
The NSL allows for life imprisonment for the four main crimes and gives Beijing authority over interpretation, overriding Hong Kong's judicial bodies. Suspects can be tried in mainland China, and the law applies to non-permanent residents and those outside the city. As of July 2023, about 260 people had been arrested, with 79 charged. The high-profile 'Hong Kong 47' trial involves pro-democracy figures accused of subversion over an unofficial primary.
The law has led to the closure of pro-democracy media outlets, including Apple Daily. Journalists report a 'feeling of fear,' and many Hongkongers have left the city, with tens of thousands relocating to the UK under a special visa. Even overseas activists face arrest warrants, such as Nathan Law.
Supporters say the NSL maintains stability and deny it weakens autonomy, but observers note its chilling effect on dissent. The law was introduced after Hong Kong's failed attempt to enact its own security legislation under Article 23 of the Basic Law, following the 2019 extradition bill protests.
