I think it's up to the countries involved (USA and Canada in this case) how they want to go about their extradition agreement.
Here, I found this:
Huawei executive to be extradited to the U.S.: Here’s how it works - National | Globalnews.ca
For an update, you might want to read "
Huawei executive's case in limbo after judge adjourns court".
The situation is not quite as simple as the media tries to make it sound for the consumers of its media output. (Mind you, I did find the description from the Canadian media source to be somewhat LESS bowdlerized than the description from the American media source.
You might also not be aware that the CANADIAN Minister of Justice has the absolute discretion to REFUSE to issue the necessary extradition papers REGARDLESS of what the court finds with respect to whether the US government has a potentially triable case (and that one of the reasons that the CANADIAN Minister of Justice has the unquestioned right to use to justify REFUSING to issue the requisite documents [regardless of the strength of the REQUESTING country's case and also REGARDLESS of whether the actions were - in fact - illegal in both countries at the time they were undertaken] is if the extradition is being sought for [in the Minister's opinion] "political reasons").
You might want to consider whether or not Mr. Trump's (
strongly implied) "If China does what we want it to do with regard to trade then we won't continue to try and extradite Ms. Meng." could potentially be enough to justify a determination that the extradition is being sought for "political reasons".
There is also the concurrent court activity with respect to whether the RCMP and the American law enforcement agencies acted illegally in the way that they went about arresting Ms. Meng. Should Ms. Meng win that case (i.e. should she be able to prove that "more likely than not" her civil rights were violated) then everything subsequent to that arrest becomes "fruit of the forbidden tree" and that, too, would justify the Minister in refusing to issue the requisite extradition documents.
Canada isn't trying to stop the extradition - she is!
Since, under the laws of Canada the government of the United States of America has the right to REQUEST that Ms. Meng be extradited, why would you be surprised that the government of Canada is complying with the laws of Canada?
Please don't tell me that that is because you find it a novel experience to see the government of a country complying with its own laws.
She's exhausting the process to fight it through the Justice system.
Indeed, and that is what the laws of Canada provide for.
PS - Canadian judges are NOT "elected". They are selected from a list of qualified lawyers prepared by the relevant provincial bar association and they are rated (on that list) for their breadth of legal knowledge, their probity, and the soundness of their legal work to date. That means that Justice Holmes (the Canadian system does not make any distinction between male and female judges) is free to make her decision completely free of any political pressure from anyone
EVEN FROM THE PRIME MINISTER OF CANADA OR FROM
THE PRESIDENT OF THE UNITED STATES OF AMERICA without fear of repercussions.
