After four days of arguments, Canadian Judge Heather Holmes has decided to reserve judgement for a later date on the topic of double criminality in the extradition case of Huawei senior executive Meng Wanzhou.

As the first formal stage of the extradition process, the four-day hearing was held to determine if Meng's alleged conduct would amount to the principle of so-called "double criminality" for extradition.

If the judge rules the legal test of double criminality has not been met, Meng will be free to leave Canada.

If she finds there is double criminality, the hearing will proceed to a second phase in June.

The extradition hearing of Huawei Chief Financial Officer Meng Wanzhou will hinge on the legal issue of double criminality, meaning the United States' allegations could be dismissed if they are not considered a crime in Canada, but if they are, she could be extradited to the US, according to experts.

Her defense team and lawyers for Canada's attorney general will debate the double criminality question before Associate Chief Justice Heather Holmes.

"If the judge finds no dual criminality conditions, it could end the trial.

If there is dual criminality found by the judge, then the trial will proceed but will take a long time, two years, maybe," Tiberghien told China Daily.
