The six defendants in two cases, were charged with endangering national security by colluding with foreign forces, and appeared in West Kowloon Magistrates' Courts on Thursday.
The prosecution applied to adjourn the case to October 12, which was approved by principal magistrate Peter Law Tak-chuen. The case will then be transferred to the High Court.
None of them applied for bail and they will be remanded in custody until then.
The first case involved former CEO Cheung Kim-hung, editor-in-chief Ryan Law Wai-kwong, Apple Daily Limited, Apple Daily Printing Limited, and AD Internet Limited.
They were charged with conspiring to ask foreign forces to sanction Hong Kong alongside founder Jimmy Lai Chee-ying from July 1 last year to April 3 this year.
The second case involved writers Yeung Ching-kee and Fung Wai-kong, executives Chan Pui-man and Lam Man-chun. They faced the same charge as well.
