A Hong Kong court will convene Thursday morning to deliver verdicts in the city's biggest case against pro-democracy campaigners since China imposed a national security law to crush dissent.
Three High Court judges are expected to take up to two days to deliver the verdicts, with the 47 defendants facing life in jail on subversion charges.
Beijing imposed a national security law on Hong Kong in 2020 after huge and sometimes violent pro-democracy protests brought the finance hub to a standstill.
Authorities then charged the 47 opposition figures from across the political spectrum with "conspiracy to subversion", saying their political activities were aimed at bringing down the government.
Sixteen defendants -- including activists, former lawmakers and district councillors -- have contested the charges and will receive verdicts this week.
The other 31 pleaded guilty, hoping for lenient sentences.
Most of the defendants have been kept behind bars since they were first brought to court in March 2021.
Thursday's verdict will show whether Hong Kong considers non-violent political participation a crime, according to Eric Lai, a research fellow at Georgetown University's Center for Asian Law.
The defendants are "significant leading figures in Hong Kong's opposition movement," Lai told AFP, calling it "a trial of the pro-democracy movement of Hong Kong."
The 16 people who will receive verdicts include veteran pro-democracy ex-lawmakers Ray Chan and "Long Hair" Leung Kwok-hung, as well as former journalist Gywneth Ho.
The trial was held without a jury and the judges were chosen from a pool of jurists handpicked by Hong Kong's leader.
If convicted, the campaigners are expected to be sentenced this year.
Prosecutors said the group of 47 had conspired to subvert state power by holding unofficial primary polls, as part of their plan to coordinate an electoral takeover of the legislature.
Once in power, they would use their majority to veto government budgets and force the city's leader to accede to five key demands raised by protesters in 2019, the court heard.
Defence lawyers have argued Hong Kong's mini-constitution had laid out mechanisms for such a plan, and that the matter was "a purely political issue rather than a legal matter".
The case has been closely watched by the international community.
The United States and other Western nations have criticised China for cracking down on democracy in Hong Kong and curtailing freedoms promised when the former British colony was handed over to Chinese rule in 1997.
In response to the 2021 arrests of the defendants, the United States had sanctioned six Chinese and Hong Kong officials.
The US consul general in Hong Kong, Gregory May, this month said Washington will be "closely watching the expected verdicts... and their sentencing".
