U.S. District Judge Ann Donnelly of the Eastern District of New York on Thursday rejected a request from attorneys defending the Chinese telecommunications giant Huawei to expand the scope of documents that can be reviewed by Huawei CFO Meng Wanzhou, who is legally classified as a fugitive from justice.

Meng, a co-defendant in the Eastern District case, was arrested in Canada in December 2018. Her extradition proceedings are ongoing and are likely to continue for many more months, Brooklyn federal prosecutors estimated Thursday.

Attorneys from Sidley Austin and Jenner & Block are defending Huawei from allegations that it violated U.S. sanctions against Iran and conspired to steal trade secrets, and they asked Donnelly for authorization to discuss discovery material on a limited basis with Meng, who has so far been allowed to review material she had personally sent or received.
