Schellenberg, 36, was arrested in 2014 and was later sentenced to a 15-year prison term for smuggling methamphetamine. During a recent retrial prosecutors said new evidence implicated him in a drug trafficking operation. The Chinese Government even invited foreign media to attend his appeal hearing - prompting speculation that Beijing wanted to use the case to exert pressure on Ottawa to free Meng.
"The procedures in Mr Schellenberg's case would be unusual even if he was a Chinese national," said Margaret Lewis, a law professor at Seton Hall University. "The fact that he is a Canadian, combined with the welcoming of foreign media to view court proceedings, makes it downright suspicious."
The Dalian Intermediate People's Court said Schellenberg conspired with three others to pack more than 200kg of methamphetamine in tyres to ship to Australia. Schellenberg has said he was framed. He has the option of appealing again within 10 days. His case is expected to be reviewed by higher courts.
