Upon the consent of the parties, pursuant to their specific written request, any other part-time magistrate judge may exercise such jurisdiction, if such magistrate judge meets the bar membership requirements set forth in section 631(b)(1) and the chief judge of the district court certifies that a full-time magistrate judge is not reasonably available in accordance with guidelines established by the judicial council of the circuit.

The consent of the parties allows a magistrate judge designated to exercise civil jurisdiction under paragraph (1) of this subsection to direct the entry of a judgment of the district court in accordance with the Federal Rules of Civil Procedure. Nothing in this paragraph shall be construed as a limitation of any party’s right to seek review by the Supreme Court of the United States.
