With a monitoring bracelet on her ankle, Huawei Technologies Chief Financial Officer Meng Wanzhou returned to the Supreme Court of British Columbia on Monday to argue that her extradition to the United States should be halted.

During scheduled hearings in Vancouver, Meng's lawyers will argue that US officials omitted details that undermine the fraud charges against her, on the basis that information provided to Canadian officials was misleading and contained "material omissions and misrepresentations".

Canadian police detained Meng at Vancouver International Airport on Dec 1, 2018, following an arrest warrant issued by the US government concerning fraud allegations. She was later released on bail and remains in the Canadian city.

Meng is accused of violating US sanctions against Iran. The US used a presentation she made to the British multinational bank HSBC in 2013 to allege that she lied about Huawei's relationship with Skycom, a Hong Kong tech firm, putting HSBC at risk of breaking US sanctions against Iran.

Meng's defense team argued that the US cherry-picked information from a PowerPoint presentation that Meng gave to HSBC. The summary omitted slides from the presentation where Meng described Huawei as having a "normal and controllable" relationship with Skycom, they said, adding that the summary of allegations provided to Canada is "manifestly unreliable "and "seriously misleading".

The defense hopes to convince the court that the accusations against Meng lack an "air of reality" and it will allow them to argue additional allegations of US abuse of process in the case.

"After she's informed HSBC that its commerce with Skycom is in Iran, HSBC is on full notice in terms of measuring the sanctions risk," defense lawyer Scott Fenton told Associate Chief Justice Heather Holmes on Monday.

"Where the court finds there are material misstatements and omissions going to the heart of the record of the case, then the court may intervene, find an abuse of process and fashion an appropriate remedy," Fenton said.

He told the judge that the "elephant in the room" was that Meng and Huawei had not lied and instead had given HSBC all the information needed to assess the risk, contrary to US claims.

Meng's defense team also said that past comments US President Donald Trump made about China prove Meng's arrest was politically motivated.

The preliminary hearing on Monday came ahead of a fuller hearing scheduled for February and will determine the legal defenses that Meng's lawyers will be allowed to use to fight her extradition.

Gary Botting, an extradition lawyer based in Vancouver, said the defense's success "depends entirely on the nature of the evidence … and whether or not there is any substance to... (the US) allegations".

In a statement issued by Huawei Canada on Monday, the company said Meng's position is that the extradition proceedings against her constitute an "abuse" of the Canadian judicial process and should therefore be "stayed".

"As expressed consistently, Huawei has confidence in Ms Meng's innocence and we trust in the Canadian judicial system to reach that conclusion. Accordingly, Huawei will continue to support Ms. Meng's pursuit of justice and freedom," the statement said.
