Grand Jury Question

NAFUSA member Peter Vaira has asked that the following question be submitted to our members:

I am testifying before a special Grand Jury Task Force created by the Supreme Court of Pennsylvania to study changes to the state investigating grand jury, and would like to provide the following information. If your state has a grand jury, is there an official grand jury procedural manual, or some document that serves that purpose, and what government entity publishes it.
