If you have served as a juror in a New York State or Federal Court within the past six years, please submit your completed questionnaire or juror summons. The questionnaires are used to determine who is qualified to serve jury duty.Jurors who do not sit on a jury trial may serve for as little as 12 days. You can get information about jury duty for City, State, and Federal courts in New York City, including State Supreme Courts. You are going to testify about some information you have about a criminal case. Your honest and complete testimony about the case is very important. The grand jury decides whether there is sufficient evidence to bring charges against someone, or indict someone with criminal charges. I served on the grand jury of the Bronx County Court House from midSeptember to midOctober this year. You are going to testify about some information you have about a criminal case. Your honest and complete testimony about the case is very important.
