What is the function of a grand jury?

The function of a grand jury is primarily to evaluate evidence and bring charges. In the legal system, grand juries serve as a mechanism to assess whether there is sufficient evidence to proceed with criminal charges against an individual. This involves examining evidence presented by the prosecution and determining whether it supports the belief that a crime has been committed. If the grand jury finds that enough evidence exists, it issues an indictment, formally charging the individual with a crime. This process is a critical step in protecting individuals from unfounded criminal charges, ensuring that there is a threshold of evidence before someone faces prosecution.

In contrast, options related to deciding civil case outcomes, administering oaths, or detaining individuals in custody are functions typically handled by other legal entities, such as trial juries or judges, rather than by a grand jury.
