Transactional Immunity for Witnesses
A lower-level member of a suspected organized crime ring is arrested and charged with armed robbery and extortion. Prosecutors have a solid case against him, but they're really trying to take down the head honcho, who's suspected of operating a multimillion-dollar racket throughout the city for the past 15 years. The defendant, who was the crime boss's personal driver and overheard a lot of high-level discussions, has information that could possibly take down the whole organization.
While the defendant isn't talking, prosecutors have their eyes on the prize and decide it's in everyone's best interests to cut a deal. They want all the details, so they grant him transactional immunity from all charges in exchange for his complete testimony.
Below is a summary look at transactional immunity for witnesses, including the differences between immunity and the right against self-incrimination.
Immunity and the Right Against Self Incrimination
You may be familiar with the right against self-incrimination. We often see it invoked by a person in a crime show or other legal drama. Grounded in the Fifth Amendment to the U.S. Constitution, it allows a witness to refuse to answer questions that would lead to criminal liability. We’ve seen dramatic displays of “taking the Fifth” in sensationalized criminal trials, like that against O.J. Simpson. One of the police investigators in that case refused to answer questions on the witness stand when asked about planting evidence at the crime scene by uttering that famous line, “I wish to assert my Fifth Amendment privilege.”
While this is one aspect of evidence and testimony, another is a grant of immunity. Even if a person asserts his or her right to refuse to testify, a prosecutor can offer a grant of immunity in exchange for that testimony. This can happen in a number of settings including:
- A court or grand jury of the United States;
- An agency of the United States; and
- Either House of Congress, a joint committee of the two Houses, or a committee or a subcommittee of either House.
Who Grants Immunity?
A federal or state prosecutor decides who will receive immunity, which can be granted for a variety of crimes from something as minor as theft to the more serious crime of murder. The prosecutor can do it by obtaining a formal court order, by writing a letter, or by making an oral commitment. When used correctly, it's a useful tool to help aide investigations and get information that a witness wouldn’t otherwise be willing to provide for fear of prosecution.
Why would a prosecutor do this in the first place? Think about the concept of “getting the biggest fish.” If you want to get to the mastermind of a crime, you often need witnesses. Why not get the mastermind’s associates to testify in exchange for immunity from prosecution for more minor crimes committed by the associates?
What Is Transactional Immunity?
There are two different types of immunity that a prosecutor can offer to a witness: "transactional immunity" (also known as “total immunity”) and "use immunity," i.e. immunity that prevents the prosecution from using the witness's own testimony or any evidence derived from the testimony against the witness.
Here, we're focused on transactional immunity. Transactional immunity is the most complete immunity that can be offered to a witness. Also known as “blanket immunity,” it protects a person from prosecution of the crime involved.
Let’s say Sally sold drugs in a certain neighborhood. While the crime of selling narcotics is serious, law enforcement might decide they would rather arrest Charlie Kingpin, the drug supplier, not Sally the small-time dealer. If Sally is offered transactional immunity from the district attorney for her participation in drug sales which helps prosecute Charlie Kingpin, Sally can’t be charged with a crime stemming from her immunized testimony.
Limitations on Transactional Immunity for Witnesses
While transactional immunity is the broadest type of immunity, it doesn’t prevent prosecution for criminal activities that are unrelated to something discussed in the immunized testimony. So if it comes out during testimony that Sally committed a robbery while dealing drugs for Charlie Kingpin, she likely won’t receive protection for that crime.
