Nine people admitted contempt of court on Tuesday over the clearance of the Mong Kok Occupy protest site in November 2014.
The nine, who were among 15 defendants appearing at the High Court, admitted they had not complied with a court injunction ordering protesters to leave the Occupy area by Nathan Road in the dying days of the pro-democracy movement.
Four others decided to contest the allegation against them and their trial will begin next week.
The court postponed proceedings against two of the defendants over concerns about their legal fees, before they could enter pleas. One of them, Lai Yu-sing, also alleged that prosecutors had fabricated facts to push for harsher sentences, denying he had bitten a policewoman's finger.
The judge warned Lai he would incur substantial legal costs should he contest the prosecution's version of events by calling witnesses and eventually not be successful.
A number of pro-democracy activists have already admitted or been found guilty of contempt, with almost all being given fines or suspended prison sentences.
However, Demosisto's Joshua Wong was jailed for three months and Raphael Wong from the League of Social Democrats for four and half months. Joshua Wong was later released on bail pending an appeal.
