About Susan

Susan Horst is a specialist in writs of mandamus and prohibition in the California appellate courts. For more than 31 years, Susan served as the writ attorney for the California Court of Appeal for the First District, Division One, in San Francisco. Susan is one of the only practicing attorneys in California to have devoted virtually her entire career to appellate writs. As writ attorney in the First District, Susan evaluated thousands of pre- and post- trial writ petitions in all types of civil and criminal matters. In the process, she learned precisely what the justices on the Court of Appeal look for before taking the extraordinary step of granting writ relief — and what an opposing party needs to highlight to have the best shot at getting a petition denied.
