The border officer who led the examination of Huawei executive Meng Wanzhou at Vancouver's airport before her arrest two years ago says he can't recall whose idea it was to collect the passcodes to her phones.

Sowmith Katragadda told a B.C. Supreme Court hearing he asked another officer to collect the codes from Meng but can't remember if the order came from one of his supervisors or if it was his own idea.

Katragadda is testifying as part of an evidence-gathering hearing in Meng's extradition case.

Her lawyers are collecting information to support an abuse of process argument in court next year alleging Canadian officers gathered evidence to aid American officials under the guise of a routine border exam.

Meng is wanted in the United States on charges of fraud and conspiracy to commit fraud related to American sanctions against Iran based on allegations that both she and Huawei deny.

Katragadda testified on Wednesday that he wanted to end the customs and immigration exam as quickly as possible so as not to unduly delay Meng's arrest by the RCMP.
