Waiver
Miranda custody, warnings, waiver, and invocation
Waiver
The warnings covered above are the first half of what Miranda demands. In Miranda v. Arizona the Court held that a statement obtained through custodial interrogation is inadmissible unless the police first give the required warnings and also obtain a valid waiver.1 A waiver is the suspect's own decision to give up the rights just described and to answer questions anyway. The analysis therefore has two gates. The first asks whether adequate warnings preceded the questioning, and the second asks whether the suspect, having heard them, validly gave up the rights. A statement that clears only the first gate is still excluded from the prosecution's case.
The reason for the second gate follows from what Miranda is trying to do. The rule does not forbid confessions, and a suspect remains free to talk to the police. What it insists on is that the decision to speak be a real choice, made by someone who knows that silence is available. Without a waiver requirement, the warnings would shrink to a formality, because officers could recite them and then proceed on the strength of the pressure that the custodial setting already supplies. The waiver standard asks two things of the suspect's choice. It must be voluntary, meaning the product of free choice and not of coercion. It must also be knowing and intelligent, meaning made with awareness of the right being given up and of what giving it up will cost.2
The same structure explains who must prove the waiver. Because the statement is inadmissible unless a valid waiver exists, the party that wants to use the statement, the prosecution, is the party that has to establish one. The allocation also fits the facts of the setting. Custodial interrogation usually takes place in a room the police control, with no one present except the officers and the suspect, so the officers hold the evidence of what was said and done. A suspect who had to prove that no waiver occurred would be trying to disprove an account of events that only the officers witnessed.
Students lose points on this issue when they treat complete warnings as the end of the analysis, because warnings that were flawlessly delivered still leave open whether the suspect gave up the rights. The next subsection sets out the voluntary, knowing, and intelligent standard in detail and the burden the government carries. The one after it takes up whether a waiver must be spoken or can be implied from a warned suspect's decision to answer.
The Valid Waiver Standard
Once adequate warnings have been given, the remaining question is whether the suspect validly gave up the rights they describe, and the law answers it with two separate requirements. The waiver must be voluntary, and it must also be knowing and intelligent.6 Each requirement guards against a different way in which a decision to talk can fail: the decision can be forced by pressure, or it can be made by someone who does not grasp what is being surrendered. A waiver defective in either respect cannot support use of the statement in the prosecution's case.7 Both requirements are judged on the particular facts of each case, including the suspect's background, experience, and conduct, and the government carries a heavy burden of proving them.8
Voluntariness asks whether the suspect's decision to speak was the product of a free and deliberate choice rather than intimidation, coercion, or deception.9 The reason follows from what the warnings are for. They exist to offset the pressure built into custodial questioning, so a decision to talk that grows out of that pressure, or out of a fresh threat added to it, is the very thing the warnings were meant to prevent and cannot count as the suspect's own choice. That is why the threat to arrest a suspect's relatives, in the example above, defeats the waiver even though the warnings were flawless. Courts judge voluntariness on the totality of the circumstances, weighing the length and conditions of the detention, the attitude the police showed toward the suspect, the suspect's physical and mental condition, and the other pressures that sap or sustain the ability to resist.10 Because the inquiry aims at coercion, a claim of involuntariness needs coercive police conduct behind it.11
Two decisions show how far the voluntariness requirement reaches. In Colorado v. Connelly, a man with a history of psychiatric hospitalization approached an off-duty officer on the street and confessed to murder, and he later explained that auditory hallucinations had driven him to do it.12 The Court held that the pressure to confess came from his own mind and not from government coercion, so no police overreaching was present and the waiver was voluntary.13 The prong therefore measures what the government did, and a suspect's internal state, however extreme, does not satisfy it alone.
Colorado v. Spring presents the opposite kind of gap. The police did not tell the suspect, before the waiver, that they planned to ask about an old murder as well as the unrelated crime for which he had been arrested, and the Court held that this silence about the subject of the questioning was not the kind of trickery that makes a waiver involuntary, in part because the suspect had been warned that anything said could be used against him.14 The Court left open whether an affirmative misrepresentation about the scope of the questioning would call for a different result.15 The two cases therefore answer different questions. Connelly puts pressure with no governmental source outside the voluntariness requirement, while Spring treats a police omission about the topic of questioning, standing alone, as something short of the deception the requirement forbids.
The second requirement concerns understanding. A waiver is knowing and intelligent when it is made with full awareness of both the nature of the right being abandoned and the consequences of abandoning it.16 The logic is the logic of any surrender of a right: a person cannot give up what the person does not know is there, and cannot weigh a choice whose cost is hidden. For that reason the inquiry looks to the particular suspect. In Edwards v. Arizona the Court said that a waiver of the right to counsel must be a knowing and intelligent relinquishment of a known right, a matter that depends on the particular facts and circumstances, including the background, experience, and conduct of the accused.17 The Court also pointed out that the trial court had found the confession voluntary without separately asking whether Edwards had knowingly and intelligently relinquished that right.18
That omission shows why the two requirements have to be kept apart, because a waiver can pass one and fail the other. A suspect whom nobody pressured has made a free choice, yet if the suspect did not understand the right, the waiver is still not knowing and intelligent. Mental illness and intellectual disability are relevant factors in assessing a waiver, but many people with those conditions are able to waive validly, and the condition alone does not make a suspect incapable of doing so.19
The same attention to the facts explains why the form of a waiver does not decide the issue. Miranda itself identified the paradigm case: an express statement that the individual is willing to make a statement and does not want an attorney, followed closely by a statement, could constitute a waiver.22 A signature is not required. In Duckworth v. Eagan the suspect twice refused to sign the waiver form, yet he told the detective that he understood his rights, that he did not want a lawyer, and that he wished to make a statement.23 The Court held that the refusal to sign did not invalidate the waiver, because the trial court had found that he was fully advised of his rights, understood them, and voluntarily waived them.24 A refusal to sign is therefore one fact among others. Where the other signs of willingness are at all ambiguous, though, the refusal weighs heavily against finding a waiver.25
The prosecution carries the burden of establishing all of this. Miranda stated that when interrogation continues without an attorney present and a statement is taken, a heavy burden rests on the government to demonstrate that the defendant knowingly and intelligently waived the privilege against self-incrimination and the right to counsel.26 The allocation rests on the fact that the State is responsible for establishing the isolated circumstances of the interrogation and alone has the means of producing corroborated evidence of what occurred during it.27 Two corollaries follow. A valid waiver will not be presumed from the suspect's silence after the warnings or from the fact that a confession was eventually obtained, and a lengthy interrogation or incommunicado detention before the statement is strong evidence that the suspect did not validly waive, since a statement at the end of such an ordeal is consistent with the pressure having finally forced it.28 The burden is tested at the pretrial hearing on a motion to suppress, where the prosecution must demonstrate the warnings and the waiver before the statement can be used.29
The waiver question is also separate from whether the suspect invoked a right. Even when warnings were given and the suspect never invoked anything, the statement is not admissible in the prosecution's case until the prosecution demonstrates a knowing and intelligent waiver.30 The next subsection shows how that burden is met when a warned suspect answers questions without ever saying words of waiver, and the invocation sections later in this chapter take up the suspect's power to cut off questioning.
Students lose this issue when they treat mental illness by itself as proof that a waiver was involuntary, because a coercion claim needs coercive police conduct behind it and the suspect's condition is only one factor in the totality.31 A second error treats a refusal to sign a form as a refusal to waive. The first error overlooks the police-conduct requirement, and the second confuses the paperwork of a waiver with its substance.
Implied Waiver
The valid waiver standard describes what a waiver must contain, but it leaves open what form a waiver must take. No particular form is required. The rule that results is implied waiver: a suspect who has received and understood the warnings and then answers questions can be found to have waived the right to remain silent through that conduct, and even a single incriminating answer can support the finding.33 The leading decision is Berghuis v. Thompkins, which applied the earlier rule of North Carolina v. Butler that a court may infer waiver from the actions and words of the person interrogated.34
The reason for the rule follows from where Miranda places its main protection. The warnings themselves are the primary safeguard for a suspect in custody, and the Miranda requirements are met when the suspect receives adequate warnings, understands them, and has an opportunity to invoke the rights before giving any answer.35 A rule demanding a spoken or signed waiver before the first question would add a ritual on top of that safeguard, and a suspect who has heard the warnings and decided to talk gains nothing from it. The suspect who wants to stop is not left unprotected, because the suspect can end the questioning by saying so. Treating a knowing, uncoerced decision to answer as a waiver therefore respects the choice the suspect actually made.
Thompkins was arrested after a shooting outside a shopping mall, and at the station a detective read him the warnings. The interrogation lasted about three hours. He was largely silent, offering only occasional answers such as “yeah,” “no,” or “I don’t know” and nodding his head, and he declined to say in writing that he understood his rights.36 Near the end, after persistent questions about God and religion, Thompkins said he “prayed to God to forgive me for shooting that boy.”37 The Court held that this answer, given after the warnings and without coercion, waived his right to remain silent.38
The Court reached that result by finding three things. The first was understanding: no one contended that Thompkins failed to grasp his rights, which indicated that he knew what he gave up when he spoke.39 The second was conduct. His answer about praying for forgiveness was a “course of conduct indicating waiver,” because a suspect who wants silence can say nothing or can say plainly that questioning should stop.40 That the answer came about three hours after the warnings did not change this, since police are not required to repeat the warnings from time to time, and his sporadic earlier answers pointed the same way.41
The third finding was the absence of coercion. Thompkins did not claim that police threatened or injured him or that he was afraid, the room was standard in size, and the questioning took place in the middle of the afternoon.42 Three hours in a straight-backed chair is not inherently coercive, because the decisions that condemned longer interrogations involved added facts such as sedation, sleep and food deprivation, or threats.43 The religious framing of the question did not make the answer involuntary either, since the privilege against self-incrimination does not reach moral and psychological pressure that comes from sources other than official coercion.44 That echoes the voluntariness discussion above, where the question was what the government did to produce the decision to talk.
Thompkins also argued that even if his answer could amount to a waiver, the police had no right to question him until they first obtained one. The Court rejected the argument because a requirement of waiver at the outset cannot coexist with the principle that waiver may be inferred from what the suspect later says and does.45 After giving the warnings, police may therefore question a suspect who has neither invoked nor waived the rights.46 Two features keep that arrangement safe for the suspect. Any waiver, express or implied, can be contradicted by an invocation at any time, and once the suspect invokes either the right to counsel or the right to remain silent, further interrogation must cease.47 And as questioning continues, the suspect learns more about the situation and can reassess whether to insist on silence or to cooperate, which supports treating a later answer as a considered choice.48
This doctrine can look as if it conflicts with the earlier point that a waiver is not presumed from silence after the warnings or from the fact that a confession was eventually obtained. The two fit together once you see what the answer supplies. The prosecution must still establish that adequate warnings were given and that the suspect understood them, and once that is shown, the suspect's uncoerced statement is itself the course of conduct that establishes the waiver.49 Silence alone supplies no such conduct, and a statement taken without warnings, or from a suspect who did not understand them, has no foundation to build on.
Students lose this issue when they assume police must obtain a waiver before asking the first question, or that a suspect who will not sign a form has refused to waive. Neither assumption holds. Officers may question a warned suspect who has not invoked, and Thompkins himself declined to say in writing that he understood his rights yet still waived by answering.52 The refusal to sign remains one fact among others, and where the other signs of willingness are ambiguous, it weighs against finding a waiver.53
Berghuis has two halves, and this section has taught only the first. The waiver half is complete: a warned suspect who understands the rights and then answers without coercion has waived. The invocation half runs the other direction and returns in the section on invoking silence. Thompkins's long silence did not invoke his right, so a suspect who wants questioning to stop has to say so clearly.54
