Federal prosecutors looking to conscript Apple into their decryption efforts are asking for an “extraordinary relief,” the company said Friday, even though the government cannot show any likely evidentiary value from the locked phone or point to legislative authorization for the compelled assistance.

In court papers filed in the Eastern District of New York, Apple urged Eastern District Judge Margo Brodie to stand by Magistrate Judge James Orenstein‘s February decision, which “soundly rejected” the prosecution’s bid for assistance under the All Writs Act of 1789.
