Court documents reveal just how complex and unusual a Meng Wanzhou trial could be

As Meng Wanzhou strolls the corridors of Vancouver's downtown B.C. Supreme Court building flanked by advisers and security guards, she moves more like royalty than a woman facing the possibility of prisonin the United States.

The chief financial officer of Chinese telecommunications giant Huaweiwill be in court for a second week on Monday, watching her lawyers as they attempt to access records of what they claim was a "covert criminal investigation" by Canadian authorities on behalf of the FBI.

Lawyers for Canada's attorney general will take their turn in front of Associate Chief Justice Heather Holmes, arguing that Meng'streatment by border officers and RCMP on the day of her arrest was nothing out of the routine.

If they're right, it would be one of the few times that could be accurately said of any part of the Meng Wanzhousaga.

'Well beyond any set of criminal charges'

Documents filed with the court in relation to this week's application which isnot Meng's actual extradition hearing include the U.S. government's outline ofitscase and an expert opinion for the defence, both of which highlight just how extraordinary a trial would be if Meng is ultimately sent to New Yorkto be tried for allegedly violating U.S. sanctions against Iran.

Meng is accused of misleading banks about transactions that would have placed them on the wrong side of American sanctions.

JohnBellinger, a former legal adviser and senior associate counsel to the George W. Bush White House, wrote a 16-page analysis of the case for Meng's legal team.

"I am unaware that the U.S. has sought to prosecute any other person for the conduct for which Ms. Meng has been indicted," wrote Bellinger, who now heads his own international law firm.

"These charges against Ms. Menggo well beyond any set of criminal charges related to violations of U.S. sanctions in Iran of which I am aware."

Huawei and Skycom

Mengwas arrested at theVancouver airport on Dec. 1, 2018, after arriving on a flight from Hong Kong.

She was expecting to travel to Mexico City later that day, with a final destination of Buenos Aires.

The 47-year-old is accused of lyingto an HSBC executive at a 2013 meeting meant toreassure the bank its business with Huawei was not putting HSBC at risk of violating U.S. sanctions against Iran.

According to court documents, HSBC was one of at least four multinational financial institutions alarmed at a series of Reuters stories detailing Huawei's relationship withSkycom, a companythat allegedlyattempted to sell U.S. computer equipment to an Iranian company.

Huawei described Skycom as a "local partner" in Tehran. But the Reuters articles suggested that Skycom was actually a Huawei subsidiary.

Meng, who sat on the board of Skycomin 2008 and 2009, allegedly told the HSBC executive that Huaweiwas in complete compliance with U.S. regulations.

'Intimidating and corrosive'

Bellinger's report details the history of American attempts to police global business with Iran.

In Meng's case, none of the transactions allegedly occurred in the U.S. but prosecutors claim they have jurisdiction becausemoney allegedly passed through the U.S. banking system.

Bellinger writes that he is "not aware of any previous criminal charges levied against a non-U.S. person"for the type of activity alleged ofMeng.

Specifically, he says he's "not aware of a case where a non-U.S. person has been criminally charged solely for having 'caused'another" non-U.S. entity in this case, a bank to violate sanctions.

What's more, Bellinger writes, when charges have been laid, they have normally been levied against institutions, not individuals let alone someone like Meng, daughter of Huawei founder Ren Zhengfei.

Meng's lawyershave also pointed to what they call "intimidating and corrosive" comments by U.S. President Donald Trump, who has suggested that Meng could be used as a bargaining chip in his country'strade war with China.

Trump's comments underpin an argument they hope will ultimately convince a judge to stay proceedings against their client for abuse of process.

Witnesses from around the world

In a record of the case filed with the court, prosecutors map out the types of witnesses a judge or jury might hear from if Meng were to be put on trial in the U.S.

They include former Skycom employees, now living in the U.S., who claim "Huawei and Skycomwere indistinguishable entities."

The documents also say confidential witnesses will testify that all employees at Skycom's Tehran office allegedly had Huawei access badges and communicated using Huawei email addresses.

The HSBC executive who allegedly met with Meng at a Hong Kong restaurant in August 2013 will also testify that Mengspoke through an English interpreter as she gave a PowerPoint presentation on Huawei and Skycom.

Witnesses from other banks are expected to come from outside the U.S. to testify that they relied on Meng's statements as they weighed the risks of continuing to clear millions in transactions for Huawei.

Meng's Vancouver lawyers claim she didn't deceive anybody.

They also say the banksin question have "extensive documentation that accurately described" the relationship between Huawei and Skycom.

A complex case

But the record of the case also hints at how complex a trial might be.

Two of the financial institutions named in the document HSBC and Standard Charter Bank entered into deferred prosecution agreements with U.S. prosecutors in 2012 for their own violations of U.S. sanctions against other countries, including Iran.

As part of those agreements, they would have been placing themselves in legal jeopardy had they had any new sanctions violations.

The deals also required them to work with U.S. prosecutors and provide witnesses for "related inquiries."

Meng's extradition hearing, which is likely to last only a few days,is set to begin in January 2020.

Later in the year, her lawyers will argue to have the extradition casetossed for alleged abuse of process related to the documents they are seeking in this week's hearing.

But any final determination is likely still many court levels of appealaway, provided a solution isn't found in the political arena.

A conclusion could take years.

And if it's like any other element of Meng Wanzhou's story, it will undoubtedly be anything but routine.
