(a)    Procedure. The chief judge of each judicial circuit shall cause a list of those persons whose names have been drawn and certified for jury duty in each of the counties within that circuit to be compiled. The lists shall be taken from the male and female population over the age of 18 years and having the other constitutional and statutory qualifications for jury duty in this state not later than the last day of the first week of December of each year. From the lists so compiled, the chief judge shall cause to be selected, by lot and at random, and by any authorized method including mechanical, electronic, or electrical device, a list of prospective grand jurors from each county whose number shall be determined on the basis of 3 jurors for each 3,000 residents or a fraction thereof in each county. The lists from which the names are drawn may be, but are not required to be, the same lists from which petit and grand juries are drawn in each county and circuit. After compilation, the statewide grand jury lists shall be submitted to the state courts administrator not later than February 15 of each year.

(b)    Population. For the purposes of this rule, the population of each county shall be in accordance with the latest United States Decennial Census as set forth in the Florida Statutes.

(c)    Excuses.

(1)    The judge appointed to preside over the statewide grand jury may issue an order appointing the chief judge of the judicial circuit where a prospective grand juror resides to determine whether service on the statewide grand jury will result in an unreasonable personal or financial hardship because of the location or projected length of the grand jury investigation.

(2)    The chief judge of the circuit shall determine whether a prospective grand juror fails to meet the qualifications of a juror in the county where the person resides. The determination shall be made only for those prospective grand jurors who contact the chief judge and request disqualification.

(3)    The chief judge of the circuit shall excuse any prospective grand juror who requests and is qualified for exemption from grand jury service pursuant to general law, or from service as a juror in the county where the person resides. The chief judge shall inform the judge appointed to preside over the statewide grand jury without delay of any determination.
