Evidence used by the United States to justify the extradition of Huawei Technologies chief financial officer Meng Wanzhou is “unreliable and defective” and should not be considered by a Canadian court, Meng’s lawyers argued in documents released to the media on Friday.

Meng, 48, was arrested in December 2018 on a warrant from the United States which alleges that she misled the bank HSBC about Huawei’s business dealings in Iran.
