Fifth Amendment

The Fifth Amendment to the U.S. Constitution is the source of some of the most important protections a criminal defendant has. It is what gives you the right to remain silent, the right not to be tried twice for the same crime, and the right to fair procedures before the government can take away your freedom. When someone “pleads the Fifth,” they are invoking the constitutional right not to be a witness against themselves.

How the Fifth Amendment Works in California

The Fifth Amendment applies to California through the Fourteenth Amendment, and many of its protections are also independently guaranteed under Article I, Section 15 of the California Constitution. Five core protections come from the Fifth Amendment: the right against self-incrimination, the protection against double jeopardy, the requirement of grand jury indictment for federal felonies, the guarantee of due process, and the right to just compensation for taken property (which is mostly relevant in civil contexts).

In California criminal cases, the right against self-incrimination is the most frequently invoked. It is the constitutional foundation for Miranda rights, and it protects you not just at the police station but throughout your case — at the grand jury, at trial, at sentencing, and even in some civil proceedings where criminal liability could attach. Under Griffin v. California, the prosecution cannot comment on your decision not to testify, and the jury cannot draw any inference from your silence at trial. CALCRIM 355 explicitly instructs jurors that they may not consider the defendant’s choice not to testify for any reason.

The Fifth Amendment also requires that any statement used against you be voluntary. California courts examine the totality of the circumstances — age, education, intoxication, length of interrogation, threats, promises, deception — to decide whether a confession was truly the product of free will. Statements that are coerced or that follow inadequate Miranda warnings can be suppressed under Penal Code § 1538.5 and related authority, and the resulting suppression often dismantles the prosecution’s case.

The double jeopardy protection of the Fifth Amendment, applied to California through the Fourteenth, prevents a person from being tried twice for the same offense after acquittal or conviction. California’s own double jeopardy statute is Penal Code § 687, and the related California rule in Kellett v. Superior Court generally requires that all charges arising from the same conduct be tried together. There are real exceptions — particularly the dual sovereignty doctrine that allows separate state and federal prosecutions — but the core protection remains a powerful shield in everyday California criminal practice.

Why the Fifth Amendment Matters to Your Defense

Invoking the Fifth Amendment effectively requires clarity. Saying “maybe I shouldn’t talk” or “I think I want a lawyer” has been treated as ambiguous by courts. The strongest invocation is direct: “I am invoking my right to remain silent. I want a lawyer.” Once invoked unambiguously, all interrogation must stop. Defense attorneys regularly review interrogation video frame by frame to identify the moment of invocation and the violations that follow it.

The right also matters at trial. The decision whether a defendant should testify is one of the most consequential in any case. Testifying opens the door to cross-examination on the charged conduct and, in some cases, prior convictions. Not testifying preserves the protection but leaves the prosecution’s narrative unchallenged from the stand. A skilled criminal defense attorney walks through this decision carefully with the client, weighing the specific facts, the strength of the prosecution’s case, and the client’s ability to hold up under cross.

For witnesses, including codefendants and family members, the Fifth Amendment can be invoked in response to specific questions. Witnesses cannot make a blanket refusal to testify, but they can decline to answer questions where a truthful answer might tend to incriminate them. Sometimes this leads to grants of immunity under Penal Code § 1324, which compel testimony in exchange for protection from prosecution. These dynamics are common in California conspiracy and white collar cases and require careful coordination between counsel.

The Fifth Amendment is closely linked to Miranda rights, the right to counsel, the protection against double jeopardy, and the guarantee of due process. It also connects to grand jury practice and immunity grants — concepts central to our criminal defense and federal defense work.
