The trial of a Hong Kong newspaper publisher who was arrested in a crackdown on the city’s pro-democracy movement was postponed on Thursday after the territory’s leader asked China to effectively block him from hiring a British defense lawyer.Jimmy Lai, 74, faces a possible life sentence if convicted under a National Security Law imposed by China’s ruling Communist Party on the former British colony.The Hong Kong government objected after judges on Monday approved Lai’s plan to hire Timothy Owen, a veteran human rights lawyer.Chief Executive John Lee asked China’s ceremonial legislature to decide whether foreign lawyers who didn’t normally practice in Hong Kong could be rejected for national security cases.Beijing imposed the security law after pro-democracy protests that started in 2019. If Beijing intervenes, it would mark the sixth time the Communist-ruled national government has stepped into the city’s legal affairs.Lai, the founder of the now-defunct Apple Daily, is accused of conspiring together with others to call for an imposition of sanctions or blockade, or engage in hostile activities against Hong Kong or China.He also faces a charge of collusion with foreign forces to endanger national security, and a separate sedition charge under a colonial-era law that is increasingly used to snuff out dissent.As of late November 25 people have been convicted under the law, which prohibits subversion, pro-independence activity, collusion with “foreign forces” and terrorism, according to the security bureau.
