How do prosecutors use grand jury indictments in federal vs. state court systems?
Executive summary
Federal prosecutors must obtain grand‑jury indictments for most felonies under the Fifth Amendment, while states vary widely — some require grand juries for felonies, others allow prosecutors to proceed by information or use different local practices (see Congressional Research Service summary and Stanford analysis) [1] [2]. Federal grand juries are larger (16–23 members) and require a 12‑member concurrence; state grand juries vary in size and unanimity rules, and state practice can include special prosecutors and local norms that differ from federal procedures [3] [4].
1. How the federal system uses grand juries: the constitutional baseline
The Fifth Amendment creates a constitutional rule that for “capital, or otherwise infamous” federal crimes the government typically must secure a grand‑jury indictment — a citizen panel that the prosecutor presents evidence to and that returns a “true bill” if it finds probable cause [1] [5]. Federal grand juries are statutorily composed of 16–23 members, require a quorum and generally 12 votes to indict, and operate largely under secrecy; the indictment must state the essential facts and elements so the defendant can prepare a defense [3] [5].
2. Federal practice vs. the prosecutor’s alternatives: informations and waivers
Despite the grand jury mandate for serious federal charges, defendants may waive indictment for non‑death‑penalty offenses and the government can prosecute some offenses by information (a charging document filed by prosecutors) under Federal Rule of Criminal Procedure 7, so grand‑jury use is powerful but not absolute in federal practice [1].
3. State systems: diversity, local rules, and special prosecutors
State grand‑jury practices vary dramatically: some states keep grand juries like the federal model, others abolished the grand jury for routine felony charging, and rules such as panel size and whether indictments must be unanimous differ — e.g., Missouri allows 9 of 12 jurors to indict — and state law often permits appointment of special or independent prosecutors in controversial cases [4].
4. Practical prosecutorial use: screening, secrecy, and control
Prosecutors use grand juries as screening tools — presenting evidence, typically without defense witnesses, to secure probable‑cause findings and formal charges; critics argue this gives prosecuting attorneys substantial influence over the process, a point reflected in the oft‑quoted observation that prosecutors can “indict a ham sandwich,” while defenders note the constitutional and procedural safeguards at work [5] [4].
5. Where federal and state use diverge in forum and tactics
Federal grand juries are governed by uniform federal rules and constitutional constraints; state approaches can be more flexible or idiosyncratic. That difference can create tactical choices: recent reporting shows federal prosecutors sometimes sought local grand juries after a federal grand jury declined to indict — a move criticized by a federal magistrate as an “end run” and “forum shopping,” underscoring tensions when prosecutors cross forum lines [2] [6].
6. Controversies and competing viewpoints: independence vs. efficiency
Reform advocates cite concerns about prosecutorial dominance and call for changes to ensure fairness; defenders argue grand juries remain a constitutional shield and practical screen that protect defendants and the public. The Congressional Research Service traces debates about fairness and efficiency in past proposals, and Stanford Law reporting documents contemporary disputes in high‑profile D.C. cases over whether using a state grand jury after a federal refusal erodes norms [3] [2].
7. What this means for defendants and the public
In federal felony cases, defendants generally are entitled to a grand‑jury indictment unless they waive it; in state cases, whether a grand jury will sit — and how it will operate — depends on the state’s laws and local practices, which can affect outcomes, timing, and public scrutiny [1] [4]. The secrecy of grand‑jury proceedings also means much of what prosecutors present is not public, which fuels both calls for transparency and arguments for protecting witnesses and investigations [5].
8. Limitations of available reporting and unanswered questions
Available sources detail constitutional rules, panel sizes, and recent controversies around prosecutors resorting to different grand juries [1] [2] [6], but they do not provide a comprehensive catalogue of every state’s grand‑jury rules or statistical comparisons of indictment rates across federal and state systems; those specifics are not found in the current reporting (not found in current reporting).
