The motion means that a Wisconsin circuit court will now re-examine the case, as Avery’s attorney Kathleen Zellner claims some evidence has been mishandled by authorities.
Steven Avery, the subject of the Netflix documentary Making a Murderer, has won a motion to appeal – a development hailed by a lawyer as a “big win” in his case.
The attorney tweeted on Monday: “We are going to have an extraordinary number of constitutional violations when we are done.
The [court of appeals] is letting us create an avalanche of evidence in this record.
