§ 331 General powers and duties of grand jury.

A grand jury's job is to look into crimes that happened in their county or that can legally be tried there. They gather information and decide whether there's enough evidence to formally charge someone with a crime.

When the grand jury finds enough evidence, they present their findings to the court in writing. This can happen in one of two ways: through an indictment or through an accusation. Both are formal documents that officially charge a person with a crime and move the case forward in the legal system.

This rule basically sets up the grand jury as an investigative body. Their main task is to review facts about possible crimes and then put those findings into a written charge so the court system can take the next steps.
