A Garrity warning is the notice a government employer gives a public employee before a compelled interview: you must answer questions about your job or face discipline, including termination, but your truthful answers cannot be used against you in a criminal prosecution. The warning takes its name from Garrity v. New Jersey, a 1967 Supreme Court decision that struck down convictions built on statements officers had given under threat of losing their jobs.1Justia U.S. Supreme Court Center. Garrity v. New Jersey, 385 U.S. 493 (1967) The protection is real, but it is narrower than most people assume, and knowing where it stops matters as much as knowing what it covers.
Who Gets a Garrity Warning
Garrity applies to public employees. Police officers, firefighters, teachers, government administrators, and anyone else working for a federal, state, or local government agency can receive one when their employer opens an internal investigation. The Supreme Court was explicit that the protection was not limited to law enforcement; it “extends to all, whether they are policemen or other members of our body politic.”1Justia U.S. Supreme Court Center. Garrity v. New Jersey, 385 U.S. 493 (1967)
The reason the doctrine works this way is constitutional. The Fifth Amendment prevents the government from compelling self-incrimination, and the Fourteenth Amendment extends that prohibition to state and local governments. When your employer is the government, an order to answer questions that could produce criminal evidence puts the government on both sides of the same case. Garrity resolves the conflict by removing the criminal use of the answers.
Private-sector employees do not get Garrity protection, even those working under government contracts. A private employer questioning you about possible criminal conduct is not the government compelling you to speak, and the constitutional shield does not reach that relationship.
What the Warning Actually Protects
The core protection is called use immunity. A statement you give after receiving a Garrity warning cannot be introduced as evidence against you in a criminal case. The federal use immunity statute goes further: neither the compelled testimony “nor any information directly or indirectly derived from such testimony” may be used against you criminally.2Office of the Law Revision Counsel. United States Code Title 18 – 6002 That second half is derivative use immunity. If you mention during the compelled interview that you were at a certain location, prosecutors cannot use that lead to pull surveillance footage and then use the footage against you.
In Kastigar v. United States (1972), the Supreme Court held that when prosecutors want to use evidence in a case where the defendant previously gave compelled testimony, the government bears the burden of affirmatively proving that its evidence “is derived from a legitimate source wholly independent of the compelled testimony.” Courts take that obligation seriously. Prosecutors have to show a clean evidence trail that never touched the compelled statements.
What the Warning Does Not Protect
The immunity has hard limits, and this is where public employees get themselves into trouble.
It does not stop your employer from disciplining you. Garrity blocks criminal use of your statements. It does nothing to prevent your agency from suspending, demoting, or firing you based on exactly what you said during the compelled interview. That is the whole design: the warning trades criminal exposure for the ability to compel administrative testimony. A well-worded Garrity advisement makes this clear on its face.1Justia U.S. Supreme Court Center. Garrity v. New Jersey, 385 U.S. 493 (1967)
It does not cover civil lawsuits. The federal immunity statute is limited by its own text to “any criminal case.”2Office of the Law Revision Counsel. United States Code Title 18 – 6002 If a member of the public later sues you in civil court, for example under Section 1983, your compelled statements from an internal investigation could potentially come in as evidence.
It does not protect lies. The immunity statute carves out “a prosecution for perjury, giving a false statement, or otherwise failing to comply with the order.”2Office of the Law Revision Counsel. United States Code Title 18 – 6002 Your truthful answers are shielded from criminal use. False answers can be prosecuted as perjury or false statements, and Garrity provides no defense.
Garrity Warning Versus Miranda Warning
People routinely mix these up. They point in opposite directions.
A Miranda warning, required during custodial police interrogation, tells you that you have the right to remain silent and that anything you say can be used against you in court.3LII / Legal Information Institute. Miranda v. Arizona (1966) Miranda protects your right to say nothing. Garrity tells you the opposite: you must speak, and in exchange your words cannot be used to prosecute you.
The settings are different too. Miranda applies when law enforcement is questioning a suspect in custody. Garrity applies when a government employer questions its own employee during an internal administrative investigation. The same underlying incident can produce both. An officer might receive a Miranda warning from outside criminal investigators and a Garrity warning from internal affairs, at different stages of the same matter.
The practical difference that matters most: under Miranda, silence cannot be held against you at a criminal trial. Under Garrity, silence can cost you your job. That is the trade at the heart of the doctrine. You do not have the option to stay quiet, but the price of speaking is capped at administrative consequences.
When Criminal and Internal Investigations Run at the Same Time
The hardest situations arise when the same conduct triggers both a criminal investigation and an internal review. This is common in law enforcement. An officer involved in a shooting can face potential criminal charges and an administrative review of whether the use of force followed policy.
The tension is obvious. If the agency compels a Garrity statement before the criminal investigation concludes, prosecutors risk contamination of their case. Even if they never read the compelled statement, a court may question whether evidence gathered afterward was truly independent under Kastigar. Agencies usually handle this by running both investigations in parallel while delaying the compelled interview until the criminal side has concluded or prosecutors have declined to file. The administrative investigation can still gather physical evidence, interview witnesses, and review recordings. What waits is the order to sit the subject employee down and compel answers.
Asking for a Union Representative
If you are a unionized public employee, you have a separate right to have a union representative present during an investigatory interview. In the federal sector, the statute requires the exclusive representative to be given the opportunity to attend “any examination of an employee in the unit by a representative of the agency in connection with an investigation” when the employee reasonably believes the examination could result in discipline and asks for representation.4Office of the Law Revision Counsel. United States Code Title 5 – 7114
These are often called Weingarten rights. You have to ask; the agency is not required to remind you the right exists. Once you ask, questioning should pause until your representative arrives and has a chance to consult with you privately. The representative can speak with you during the interview, raise facts the investigator hasn’t considered, and take an active role in the discussion. In the federal system, the representative must come from the exclusive union that represents your bargaining unit.5U.S. Federal Labor Relations Authority. Part 3 – Investigatory Examinations State and local rules vary, but the basic principle is broadly the same for unionized public employees.
What To Do When You Receive One
Read or listen to the warning carefully. A proper Garrity advisement tells you two things: that you are required to answer questions about your job duties, and that your answers cannot be used against you in a criminal prosecution. If the warning is vague, or if you are unsure whether your statement is being compelled, say so on the record. Whether a statement is voluntary or compelled controls everything that follows. A statement you give voluntarily, with no threat of discipline for refusing, does not carry Garrity protection.
If you belong to a union, ask for your representative before you answer substantive questions. Requesting representation is not insubordination. If you are not unionized, ask whether you can consult an attorney. Counsel can tell you whether the warning is properly worded and whether any parallel criminal matter changes your calculus.
Then answer truthfully. Garrity shields honest answers from criminal use; it does not license false ones.2Office of the Law Revision Counsel. United States Code Title 18 – 6002 If you don’t remember something, say so. If a question falls outside your duties, your representative or attorney can raise that objection. Stonewalling gets you fired. Fabricating gets you prosecuted. Answering honestly is what the immunity is built to protect.
