A high-profile subversion trial is currently taking place in Hong Kong, where some of the city's most prominent pro-democracy activists are facing charges under a law imposed by China's ruling Communist Party. The trial is considered the biggest prosecution yet under the national security law, and if convicted, the activists could face life imprisonment. The defendants, among the 47 activists arrested in 2021, are accused of attempting to paralyze the government and overthrow the city's leader by securing a majority to veto budgets. The trial involves well-known activists such as legal scholar Benny Tai, former student leader Joshua Wong, and former opposition party leaders Wu Chi-wai and Alvin Yeung.

Prosecutors argue that unlawful means to subvert state power do not necessarily require force or physical violence, as social media and easy communication channels can be manipulated to endanger national security. The defense lawyers argue that the activists were seeking to hold those in power accountable and were pushing for democratic elections to allow residents to choose the city's leader and lawmakers, which should not be considered subversion. The trial is widely seen as part of China's crackdown on Hong Kong's pro-democracy movement, which has faced increasing restrictions since the introduction of the national security law.

Many pro-democracy politicians and activists have been jailed, gone into self-exile, or disappeared from the city's political scene. The erosion of Western-style civil liberties and the Chinese government's crackdown have led to a significant number of young professionals and middle-class families emigrating from Hong Kong. The national security law criminalizes secession, subversion, collusion with foreign forces, and terrorism. In addition to the activists on trial, pro-democracy publisher Jimmy Lai is also facing collusion charges under the law. The court's final verdict is expected to be delivered in the coming months, with tensions high and pro-democracy supporters rallying outside the court, carrying placards calling for the release of the 47 activists and waving the British flag as a show of support.
