Dozens of protesters marched from Legco to the Law Society's office in Central on Wednesday calling on the professional body to hold a disciplinary hearing into one of its members, Junius Ho.
Ho, who’s also a lawmaker, called at the weekend for people who advocate Hong Kong independence to be killed.
The protesters, including members from Demosisto, the League of Social Democrats and People Power, said if the authorities fail to take action against Ho for his remarks, the public will be left with the impression that the rich and powerful can get away with anything, while those who take part in civil disobedience movements are prosecuted.
Ousted League of Social Democrats lawmaker Leung Kwok-hung said the Law Society should ensure the professional conduct of its members.
“Mr Ho’s case is another example to the Law Society to make sure that their members are capable to uphold the justice and rule of law, instead of [advocating] murdering,” he said.
Pro-democracy lawmaker Claudia Mo said the opposition camp would seek to condemn Ho in Legco, which could lead to his disqualification as a lawmaker.
Earlier in the day, Security Secretary John Lee confirmed that the police were looking into complaints made about Ho's comments.
Ho was previously a president of the Law Society but lost his bid for re-election to the post earlier this year.
The pro-Beijing lawmaker has berated those who've been openly critical of his comments at the weekend, saying their level of Chinese is so poor they must have misunderstood what he meant.
