The Jury Services office of the San Diego Superior Court does not call citizens to request payments for failing to appear for jury duty. All requests to be excused from jury service must be submitted in writing prior to Jury Service.Prior to your first reporting date, you MUST always call the 800-998-9035 after 6PM to obtain the status of your excuse request. San Diego County residents can now submit online requests for exclusion from jury service, Superior Court officials announced. Go to the Jury Portal. The site is listed on the paperwork. The grand jury is a body of 19 citizens who are charged and sworn to investigate county matters of civil concern as well as inquire into public offenses. To defer jury service you may either use the Juror Questionnaire Portal or automated phone system at 1-909-884-1858. I've gotten a letter telling me I'm being considered as a juror for US District Court for the Southern District of California. How often must I serve?
