The Court of Final Appeal ruled Thursday that the case raised a legal question of “great and general importance” and scheduled a hearing for Nov 22.
The decision came days after the 34th anniversary of the 1989 Tiananmen Square crackdown on Sunday.
Chow faces further prosecutions, including charges under the national security law that carry sentences of up to a decade in jail.
She was arrested the morning of Jun 4, 2021, when her articles published on social media and in a newspaper called on residents to “light candles to seek justice for the dead”.
At the time, police said that the vigil was banned due to the COVID-19 pandemic and that thousands of officers would be on standby to halt any “unlawful assemblies”.
Hong Kong was once the only Chinese city that could commemorate the incident of Jun 4, 1989, when the government sent troops to crush demonstrations in Tiananmen Square calling for political change.
While the commemoration is forbidden in mainland China, tens of thousands would gather every year in Hong Kong’s Victoria Park to hold a candlelight vigil.
But public mourning for the victims of the Tiananmen crackdown has been driven underground since Hong Kong outlawed the vigil in 2020.
On Sunday, the area around Victoria Park saw heavy police presence, with officers searching people and briefly detaining some who carried flowers or held a candle – which were taken as signs of mourning.
