Meng Wanzhou scored a victory in her battle to fight extradition Thursday as the judge overseeing the proceedings agreed to let the Huawei executive’s lawyers pursue their claim that the United States misled Canada about the basics of the case. In a ruling posted online, Associate Chief Justice Heather Holmes said there was an “air of reality to Ms. Meng’s allegations of abuse of process in relation to the requesting state’s conduct.” At a hearing held last month, the chief financial officer’s lawyers said they believed the evidence was strong enough to prove that the United States omitted key components of the case that undermine allegations of fraud against their client.
