Massachusetts Consent-Refusal of Magistrate Judge Jurisdiction is a process that allows parties involved in civil litigation to decide whether the case is heard by a Magistrate Judge or a District Judge. The parties can either agree to have the case heard by a Magistrate Judge or refuse to have the case heard by a Magistrate Judge. In either case, the parties must submit a formal written document to the court, either consenting to or refusing the Magistrate Judge's jurisdiction. There are two types of Massachusetts Consent-Refusal of Magistrate Judge Jurisdiction: voluntary and mandatory. Voluntary Consent-Refusal allows the parties to agree to have the case heard by a Magistrate Judge or to refuse the Magistrate Judge's jurisdiction without the court's involvement. Mandatory Consent-Refusal requires the court to determine if the parties agree to have the case heard by a Magistrate Judge or to refuse the Magistrate Judge's jurisdiction. The court can then make a decision whether to accept or reject the parties' Consent-Refusal.
