The party against whom a citation is issued may, within 20 days of the date of the citation, sign the request for a hearing found on the back of the citation, and mail it to the Registrar at the address indicated on the citation.  The Registrar will notify the Clerk Magistrate of the District Court for the judicial district in which the infraction occurred of the request for hearing, and the Clerk Magistrate will schedule a hearing on the matter.  Any party may appeal the Clerk Magistrate's decision to a justice of the District Court, who will hear the case de novo.  The party must notify the Clerk Magistrate of its intent to appeal to a justice prior to the conclusion of the Clerk Magistrate's hearing, unless the Clerk Magistrate allows additional time to do so.   Within 10 days of the justice's decision, any party may appeal questions of law to the Appellate Division of the District Court by filing a "claim of appeal" form in the District Court Clerk's Office.  Within 30 days of the Appellate Division's decision, any party may appeal to the Appeals Court by filing a notice of appeal in the District Court Clerk's Office.
