Under New York State law, unless the defendant consents, all felony cases must be presented to the Grand Jury. Grand Juries are empowered to hear evidence presented by prosecutors, and to take various actions regarding the evidence and legal charges they are to consider. The Grand Jury can also conduct independent investigations. Grand Juries sit for a term of approximately one month. Each Grand Jury is comprised of 23 citizens who hear and examine evidence concerning offenses and take action based on such evidence.
