Grand Jury Investigations Aren’t Trials – Here’s What You Need to Know

Being subpoenaed for a grand jury might seem like an opportunity to clear things up, but it’s much more serious. If you’ve received a subpoena, don’t take it lightly. A grand jury isn’t a trial, and it’s not a place where witnesses get to tell their side of the story. 

It’s a calculated investigative machine designed to determine whether charges should proceed. Unlike other legal proceedings, the threshold for bringing charges is extremely low, and your lawyer can’t be present in the room while you’re being questioned. 

Knowing exactly how a grand jury works can help you avoid making your situation worse and giving the prosecution an advantage.

A grand jury isn’t a trial

Grand juries don’t weigh guilt or innocence. They exist only to establish probable cause. However, the bar for probable cause is exceptionally low compared to the standards required during a trial. That’s why the government secures indictments at extremely high rates (over 99% in federal cases).

“Most people don’t realize it takes less evidence to secure an indictment than a search warrant,” says an attorney from SBBL Law. “In my xx years of handling federal investigations, I’ve watched clients get indicted for answering a question too confidently. They didn’t realize a single inconsistent detail can open the door to charges.”

This reality can be shocking if you believe grand jurors scrutinize every claim like they do in a trial court. But a grand jury operates in secret and there is no defense attorney to challenge assumptions or misleading framing. The prosecutor presents all the evidence, controls the entire narrative, and doesn’t have to show anything exculpatory. They determine which witnesses to call, what documents to show, and offer a one-sided perspective. That’s why grand juries secure so many indictments.

A grand jury doesn’t trigger Double Jeopardy protections

When a grand jury chooses not to indict you, your case can be revisited at a later time and another grand jury can issue a criminal indictment.

What a grand jury actually does

Grand juries often start their investigations months or years before charges are brought. A target won’t know they’re under investigation until the prosecutor has gathered enough evidence. For example, they’ll subpoena documents from businesses, banks, employers, and third parties long before the target knows they’re being investigated. By the time you’re informed, they’ve already made their case.

There are between 16 and 23 members who sit on a grand jury, but only 12 must concur to indict. Most grand juries sit for no longer than 18 months, but the process can take up to 36 months in some districts.

Know your rights

Your Fifth Amendment rights apply while you’re being questioned, and it’s important to invoke this right when your answer might be misinterpreted or contradicted. A lot of indictments are obtained from simple inconsistent statements, not actual crimes.

The prosecutor will craft questions designed to trap you, and it’s critical to know when to stay silent. Invoking your Fifth Amendment right to remain silent won’t be treated as an admission of guilt.

What prosecutors are looking for

Prosecutors don’t have to prove your guilt to secure an indictment. They only need enough evidence to build a plausible narrative. They will ask questions designed to highlight inconsistencies and suggest motives. Unfortunately, even innocent witnesses can become targets when their answers conflict with other evidence.

They’ll also ask questions they know the answer to, and if your replies even slightly differ from documents or prior statements, they’ll use that against you. If they don’t have enough evidence for an indictment, they’ll press you until you make a contradictory statement and use that to secure the indictment. 

For example, Martha Stewart wasn’t convicted of insider trading. She was suspected of insider trading but was convicted of lying to investigators and obstruction based on statements she voluntarily offered. Prosecutors couldn’t prove the underlying crime, but she still did time anyway.

With a grand jury, intent is usually inferred rather than proven. A poor choice of words or oversimplified answer can be interpreted as concealment and that alone can be enough to secure an indictment.

Some indictments get dismissed

Despite the high rate of indictments, many end up getting dismissed. In most cases, indictments are dismissed when they’re found to have been obtained through constitutional rights violations. But it’s not something you can do on your own. It’s critical to work with a federal defense attorney when you’re after a dismissal.

Protect yourself now

A grand jury investigation isn’t an opportunity to tell your side of the story. It’s a process stacked against you from the start, and even innocent people can get pulled into charges. If you receive a subpoena, don’t wait to contact a federal defense attorney to minimize your risks and keep you from making careless mistakes.
