Confession Admissibility — Three Gates
Miranda · Voluntariness · Corpus Delicti
Three Gates to Admissibility
| Gate | Standard / Burden | What to Show |
|---|---|---|
| Gate 1 — Miranda | Government must prove waiver by a preponderance of the evidence | No custodial interrogation without Miranda warnings, OR valid waiver of Miranda rights, OR exception applies (spontaneous statement, public-safety, non-interrogation) |
| Gate 2 — Voluntariness | Government must prove voluntary by a preponderance of the evidence | The statement was the product of the defendant's free will — no police coercion overcoming the defendant's will; totality of circumstances |
| Gate 3 — Corpus Delicti | Government's burden — independent corroboration of the crime | A confession alone is insufficient to convict; independent evidence must establish that the crime occurred (not necessarily that this defendant committed it) |
1. Gate 1 — Miranda Triggers
Miranda warnings are required only when TWO conditions are simultaneously met: (1) CUSTODY — the defendant is in custody or otherwise deprived of freedom of action in a significant way; AND (2) INTERROGATION — the defendant is subjected to express questioning or its functional equivalent (words or actions the officer should know are reasonably likely to elicit an incriminating response). Miranda v. Arizona, 384 U.S. 436 (1966).
Custody Indicators
- Formal arrest Always custody.
- Traffic stop Generally not custody — Berkemer v. McCarty. However, if the stop escalates to an arrest or a reasonable person would not feel free to leave, custody may attach.
- Terry stop Generally not custody — brief investigative detention is not custody for Miranda purposes. If the stop elevates to a restraint of freedom of movement akin to arrest, custody attaches.
- Interrogation at the police station Not automatically custody — Beckwith v. United States. Examine whether a reasonable person would have felt free to leave. Voluntary presence at the station ≠ custody.
- Handcuffs / locked in a patrol car Strong custody indicator. A reasonable person in handcuffs in a locked patrol car is in custody.
- Confrontational / accusatory questioning Relevant to the objective 'free to leave' analysis — not determinative alone.
What Is NOT Interrogation
- Spontaneous statements Volunteered statements not in response to questioning are not the product of interrogation. Rhode Island v. Innis. Document that the officer did not ask a question or take any action designed to elicit the statement.
- Routine booking questions Name, address, date of birth — administrative booking questions are not interrogation even in custody. Pennsylvania v. Muniz (narrow exception for booking).
- Public safety exception Questions reasonably prompted by a concern for public safety (e.g., 'where is the gun?') do not require Miranda warnings before the question is asked. New York v. Quarles. The answer and any physical evidence found as a result are admissible.
2. Waiver & Invocation of Miranda Rights
Waiver — Moran v. Burbine / Berghuis v. Thompkins
A valid waiver must be: (1) KNOWING — the defendant understood the nature of the rights being waived; and (2) VOLUNTARY — the waiver was the product of free will, not coercion. Moran v. Burbine, 475 U.S. 412 (1986). The waiver need not be express — implied waiver from conduct (answering questions after being warned) is sufficient. Berghuis v. Thompkins, 560 U.S. 370 (2010): a suspect who is advised of Miranda rights, who makes no invocation, and who then makes incriminating statements after 2+ hours of silence has impliedly waived. The waiver burden is on the government by a preponderance.
- Express waiver Defendant signs a Miranda waiver form or verbally states they understand their rights and wish to speak. The gold standard — always use a waiver form.
- Implied waiver Defendant receives Miranda warnings, does not invoke, and then voluntarily answers questions. Berghuis. Document the sequence precisely.
- Waiver vulnerabilities to anticipate Intellectual disability / low IQ; mental illness; intoxication; youth; English as a second language; lengthy prior interrogation before warnings given (Missouri v. Seibert).
Invocation — Clear and Unambiguous
| Type | Standard | Effect |
|---|---|---|
| Right to silence | Defendant must invoke unambiguously — Berghuis. 'Maybe I should stop talking' is ambiguous and does not invoke. 'I don't want to talk to you' invokes. | Officers must 'scrupulously honor' the invocation (Michigan v. Mosley). May re-approach after a significant interval on a different crime with fresh warnings. |
| Right to counsel | Unambiguous request for an attorney — Edwards v. Arizona. 'I think I might need a lawyer' is ambiguous (Davis v. United States) and may not invoke. | All interrogation MUST CEASE once counsel is invoked. May not re-approach without the attorney present unless defendant re-initiates. Edwards. |
3. Gate 2 — Voluntariness
Separate from Miranda: even a validly Mirandized statement must be voluntary — the product of the defendant's free will, not police coercion overcoming the defendant's resistance. The totality test comes from Schneckloth v. Bustamonte, 412 U.S. 218 (1973) — ⚠️ a consent-to-search case that borrowed the test from the confession line, so cite it for the test, not as a confession holding. The absence of police coercion is essential — Colorado v. Connelly, 479 U.S. 157 (1986) holds that a confession is not involuntary absent some coercive police conduct; the defendant's own mental illness does not render a confession involuntary without coercion.
Voluntariness Factors — Totality Analysis
| Factor | Coercion Weight |
|---|---|
| Duration of interrogation | Extended interrogation (hours without break) weighs toward involuntary |
| Physical condition of defendant | Intoxication, injury, exhaustion weighs toward involuntary if severe; mild intoxication alone insufficient |
| Threats or promises | Explicit threats of harm, or promises of leniency, are classic coercion; a general statement that cooperation helps is not a promise |
| Deprivation of food/water/sleep | Prolonged deprivation weighs toward involuntary |
| Age and experience of defendant | Juvenile and first-time offenders receive more protection; prior criminal experience weighs toward voluntary |
| Miranda warnings given | Warnings given and understood weighs toward voluntary |
| Waiver form signed | Written waiver weighs significantly toward voluntary |
| Mental disability | Alone insufficient (Connelly); only relevant with accompanying coercive police conduct |
Police Tactics — Permissible vs. Not
| Tactic | Permissible? |
|---|---|
| Lies about evidence ('we have your DNA') | Generally permissible — Frazier v. Cupp. Courts weigh the deception in the totality; extreme deception may weigh toward involuntary. |
| Downplaying the seriousness of the offense | Generally permissible — but explicit false promises of leniency are not |
| Good cop / bad cop | Generally permissible — emotional appeals and sympathy are not coercion |
| Explicit promises of a specific benefit (e.g., 'cooperate and you won't be charged') | Not permissible — a specific, unconditional promise of leniency renders a confession involuntary |
| Physical coercion / pain | Never permissible — automatic involuntary |
| Threatening harm to the defendant or family | Never permissible — automatic involuntary |
| Sleep deprivation over extended period | Extreme sleep deprivation may render a statement involuntary — document rest periods |
4. Gate 3 — Corpus Delicti
Virginia Rule: a defendant may not be convicted on the basis of their confession alone — there must be independent corroboration establishing that the crime actually occurred. Watkins v. Commonwealth, 238 Va. 341 (1989). The corroboration need not prove the defendant's identity as the perpetrator — it need only establish the corpus delicti (the body of the crime: that a crime was committed). Cherrix v. Commonwealth, 257 Va. 292 (1999). ⚠️ But note what Watkins adds: where the accused has fully confessed, only SLIGHT corroboration is required, and the confession is itself competent evidence tending to prove the corpus delicti.
Corroboration Evidence — 9 Sources
| Source | What It Establishes |
|---|---|
| Physical evidence of the crime | A victim with injuries consistent with assault; a scene consistent with burglary; a body consistent with homicide |
| Medical examiner / forensic evidence | Manner and cause of death in homicides; injury documentation in assaults |
| Victim testimony | The victim's account that a crime occurred — independent of the confession |
| Witness testimony | Third parties who observed the crime or its aftermath |
| Scene evidence | Damage, trace evidence, position of body, forced entry — the scene itself corroborates the crime's occurrence |
| Recovery of stolen property | In theft cases, recovery of the item corroborates that a theft occurred |
| Electronic evidence | Cell records, GPS data, surveillance footage showing the event |
| Forensic analysis | DNA, fingerprints, bloodstain patterns, fire investigation — independent scientific proof of the event |
| Co-defendant / cooperating witness | Independent testimony about the crime's occurrence (distinct from the defendant's own statement) |
5. Direct Exam — Admitting the Confession
A. Officer Background
- What is your current assignment? How long have you been with this agency?
- Describe your training in interview and interrogation techniques.
B. Custody — Establishing (or Negating)
- When and where did you first make contact with the defendant?
- Were you in uniform? Was your weapon visible?
- At the time of the interview, was the defendant free to leave? How do you know — was that communicated to the defendant?
- Was the defendant handcuffed, restrained, or in a locked location?
- Was the defendant under arrest at the time you began the interview?
C. Miranda Warnings (if applicable)
- Before questioning the defendant, did you advise them of their Miranda rights?
- How did you do that — from memory, from a card, or using a printed form?
- Did the defendant indicate they understood their rights? How?
- Did the defendant invoke their right to remain silent or request an attorney?
- Did the defendant sign a waiver form? [Introduce the form as an exhibit.]
D. The Statement — Circumstances
- Describe the setting — where was the interview conducted? How long did it last?
- Who was present during the interview?
- Was the defendant given food, water, or breaks during the interview?
- Was the defendant's physical or mental condition affected by any substance, injury, or illness during the interview?
- Was the interview recorded? [Introduce the recording.]
- Did you make any promises or threaten the defendant in any way?
E. The Content of the Statement
- In your own words, describe what the defendant told you. [If recorded, play the relevant portion and allow the officer to authenticate before playing.]
- Did the defendant describe how, when, where, and why [the crime occurred]?
- Did the defendant identify any other participants?
- Were there any details in the confession that only the perpetrator would know — details that were not made public or shared with the defendant before the interview?
F. Corpus Delicti Anchor
- Setting the confession aside, what physical evidence or other independent evidence confirmed that [the crime] had occurred?
- [This establishes the independent corroboration on the record before the confession comes in.]
G. Post-Statement Actions
- After the statement, did the defendant take investigators to any location or lead them to any evidence?
- What did investigators find as a result? [Fruit of the confession — admissible if voluntarily given.]
6. Recorded vs. Unrecorded Statements
| Issue | Recorded | Unrecorded |
|---|---|---|
| Admissibility | Same rules — recording does not automatically make it admissible | Same rules — unrecorded statements are not automatically inadmissible in Virginia |
| Authentication | Authenticate by officer who made or preserved the recording; may also use chain of custody; confirm no editing | Officer testifies to the substance and verbatim words if possible; contemporaneous notes are helpful |
| Defense attacks | Selective editing, incomplete recording, audio quality | Coercion, misremembering, fabrication — harder to defend without a recording |
| Jury perception | Powerful — the jury hears the defendant's voice and words; demeanor evidence | Officer's credibility is the foundation — cross-examination will focus on whether the officer accurately recounted the statement |
| Best practice | Record all interviews; authenticate carefully; disclose the recording in discovery | If not recorded, prepare the officer on the exact words used and the circumstances |
7. Special Scenarios
| Scenario | Key Rule |
|---|---|
| Juvenile confession | § 16.1-247: in a custodial interrogation of a juvenile, the juvenile's parent/guardian must be notified and given the opportunity to be present before the juvenile is interrogated (with limited exceptions). Failure may render the confession inadmissible. |
| Statement made to private person (not law enforcement) | Miranda does not apply to private interrogations — not state action. Voluntariness still applies as a weight issue, not an admissibility question. |
| Statement made after unlawful arrest | Fruit of the poisonous tree (Wong Sun): statement made following an unlawful arrest may be suppressed if it is the product of the illegality. A subsequent Miranda warning does not automatically purge the taint — see Brown v. Illinois. |
| Mid-stream Miranda (Missouri v. Seibert) | Two-step interrogation: officers question without Miranda, obtain a confession, then give Miranda warnings and re-question. The post-warning confession may be suppressed as a continuation of the pre-warning interrogation. |
| Foreign national — Article 36 Vienna Convention | Failure to advise a foreign national of their right to consular notification is a Vienna Convention violation — no automatic suppression, but a factor in the voluntariness analysis and can affect extradition. |
| Statement made to a cellmate / jail informant | No Miranda issue (not law enforcement) but Fifth Amendment right to counsel (Massiah v. United States) applies — if a formal proceeding has begun, deliberately eliciting statements through a government informant without counsel present violates Massiah. |
| Defendant's silence after Miranda warnings | Post-Miranda silence may not be used as substantive evidence of guilt (Doyle v. Ohio) — it can be used to impeach prior inconsistent statements only. |
| Pre-arrest silence | Jenkins v. Anderson: pre-arrest silence (before Miranda warnings) may be used to impeach if the defendant later testifies. Salinas v. Texas: pre-arrest, pre-warning silence in a non-custodial interrogation may be used against the defendant at trial. |
| Statement made in violation of Sixth Amendment | After formal proceedings begin, the Sixth Amendment right to counsel attaches on the charged offense — deliberate elicitation without counsel present violates Massiah. The remedy is suppression. |
| Impeachment use of suppressed statements | A statement suppressed under Miranda for use in the government's case-in-chief may still be used to impeach the defendant if they testify inconsistently at trial — Harris v. New York. |
8. Key Cases
Miranda v. Arizona 384 U.S. 436 (1966)
binding
Foundational — Miranda warnings required before custodial interrogation; without warnings or valid waiver, statements are inadmissible in the prosecution's case-in-chief.
Berghuis v. Thompkins 560 U.S. 370 (2010)
binding
Implied waiver — a suspect who receives Miranda warnings, does not invoke, and then makes incriminating statements after hours of interrogation has impliedly waived. Burden on government to prove waiver by preponderance.
Edwards v. Arizona 451 U.S. 477 (1981)
binding
Right to counsel — once a suspect invokes the right to counsel, all interrogation must cease; police may not re-initiate questioning without the attorney present unless the suspect re-initiates.
Davis v. United States 512 U.S. 452 (1994)
binding
Invocation must be unambiguous — 'Maybe I should talk to a lawyer' is an ambiguous remark that does not invoke the right to counsel.
Moran v. Burbine 475 U.S. 412 (1986)
binding
Waiver is knowing and voluntary — failure to inform the suspect that an attorney was trying to reach them does not vitiate an otherwise knowing and voluntary waiver.
Missouri v. Seibert 542 U.S. 600 (2004) (plurality)
binding
⚠️ A PLURALITY — Souter, joined by three; Kennedy concurred in the judgment on narrower grounds and is therefore the controlling opinion in most courts. Kennedy's test: where a deliberate two-step strategy is used, post-warning statements related to the substance of the pre-warning ones must be excluded UNLESS CURATIVE MEASURES ARE TAKEN before the post-warning statement.
New York v. Quarles 467 U.S. 649 (1984)
binding
Public safety exception — where the officer has a reasonable concern for public safety (e.g., locating a discarded weapon), Miranda warnings need not precede the question; the answer is admissible.
Berkemer v. McCarty 468 U.S. 420 (1984)
binding
"[P]ersons temporarily detained pursuant to such stops are not 'in custody' for the purposes of Miranda." ⚠️ But the sheet's summary used to stop there: "If a motorist who has been detained pursuant to a traffic stop THEREAFTER IS SUBJECTED TO TREATMENT THAT RENDERS HIM 'IN CUSTODY' for practical purposes, he will be entitled to the FULL PANOPLY of protections prescribed by Miranda."
Colorado v. Connelly 479 U.S. 157 (1986)
binding
Voluntariness — a confession is not rendered involuntary solely by the defendant's mental illness; coercive police conduct is required.
Schneckloth v. Bustamonte 412 U.S. 218 (1973)
binding
Totality of the circumstances; the subject's characteristics and the police conduct are both relevant. ⚠️ READ THE CAPTION — Schneckloth is a FOURTH AMENDMENT CONSENT-TO-SEARCH case, not a confession case. It borrows its totality test from the confession cases, so it reads across, but do not cite it as if it decided confession voluntariness.
Harris v. New York 401 U.S. 222 (1971)
binding
Impeachment use — a statement obtained in violation of Miranda may be used to impeach the defendant if they testify inconsistently at trial.
Watkins v. Commonwealth 238 Va. 341, 385 S.E.2d 50 (1989)
binding
THE RULE IS NARROWER THAN IT SOUNDS, AND IT FAVOURS THE COMMONWEALTH. Corroboration is not required of "all the contents of the confession, or even of all the elements of the crime" — it is limited to the facts constituting the corpus delicti. And "where . . . the accused has fully confessed the crime, ONLY SLIGHT CORROBORATIVE EVIDENCE IS NECESSARY". The confession is itself competent evidence tending to prove the corpus delicti.
Cherrix v. Commonwealth 257 Va. 292, 513 S.E.2d 642 (1999)
binding
Corpus delicti is "the fact that the crime charged has been actually perpetrated", and "if the accused has fully confessed . . . then only slight corroboration of the confession is required to establish corpus delicti beyond a reasonable doubt". ⚠️ This is the Supreme Court of Virginia, not the Court of Appeals — the sheet formerly said Va. App.
Jackson v. Commonwealth 255 Va. 625, 646, 499 S.E.2d 538, 551 (1998)
binding
The slight-corroboration rule in the form Cherrix quotes it. ⚠️ Replaces a "Jefferson v. Commonwealth, Va. App. (various)" entry that carried no citation and could not be verified; the proposition it stated is carried by Watkins, Clozza and this case.
9. Pre-Trial Checklist
- Custody determination made — was the defendant in custody at the time of the statement?
- If in custody: Miranda warnings given before questioning? Waiver obtained (express or implied)?
- Miranda form signed and preserved — introduce as an exhibit
- Invocation checked — any indication of invoking silence or counsel? If so, was questioning properly halted?
- Voluntariness assessed — no threats, promises, coercion; document rest breaks and defendant's condition
- Corpus delicti corroboration identified independently of the confession — physical evidence, witnesses, or scene
- Statement recorded? Recording preserved and authenticated through chain of custody
- Spontaneous statement? Document the exact context — what the officer said/did before the statement was made
- Juvenile defendant? § 16.1-247 parental presence requirements met
- Foreign national? Article 36 Vienna Convention notification given
- Fruit of the confession (evidence found as a result) preserved and disclosed
- Missouri v. Seibert two-step issue assessed — was there any pre-warning questioning?
11. Annotated Authority
Annotated authority — research layer, not printed on the PDF
Watkins v. Commonwealth 238 Va. 341, 385 S.E.2d 50, Va., 1989
THE VIRGINIA CORPUS DELICTI RULE, AND IT IS NARROWER THAN THE SHORTHAND SUGGESTS. "It is NOT NECESSARY, however, that there be independent corroboration of ALL THE CONTENTS OF THE CONFESSION, OR EVEN OF ALL THE ELEMENTS OF THE CRIME. The requirement of corroboration is LIMITED TO THE FACTS CONSTITUTING THE CORPUS DELICTI." Further, "where, as here, the accused has FULLY CONFESSED the crime, ONLY SLIGHT CORROBORATIVE EVIDENCE IS NECESSARY to establish the corpus delicti." And "THE CONFESSION IS ITSELF COMPETENT EVIDENCE TENDING TO PROVE THE CORPUS DELICTI, and all that is required of the Commonwealth in such a case is to present evidence of such circumstances as will, WHEN TAKEN IN CONNECTION WITH THE CONFESSION, establish the corpus delicti beyond a reasonable doubt."
Practical value: The sheet used to state only the defence-facing half of this rule — that a confession alone will not convict. Every other sentence runs the Commonwealth's way. After a full confession the bar is SLIGHT corroboration, of the corpus delicti only, and the confession itself counts toward it. ⚠️ Note the condition: "where, as here, the accused has FULLY CONFESSED". A partial or equivocal admission does not obviously buy the slight-corroboration standard, and that is where the argument will be.
Cherrix v. Commonwealth 257 Va. 292, 513 S.E.2d 642, Va., 1999
"In EVERY criminal prosecution, the Commonwealth must prove the element of corpus delicti, THAT IS, THE FACT THAT THE CRIME CHARGED HAS BEEN ACTUALLY PERPETRATED." And "if the accused has FULLY CONFESSED that he committed the crime, then ONLY SLIGHT CORROBORATION of the confession is required to establish corpus delicti beyond a reasonable doubt."
Practical value: The cleanest one-sentence definition of corpus delicti in the Virginia reports, and the modern restatement of Watkins. ⚠️ TWO CORRECTIONS TO WHAT THIS SHEET USED TO SAY. It listed Cherrix as a COURT OF APPEALS decision; it is the SUPREME COURT OF VIRGINIA. And it carried no citation at all. ⚠️ Read the caption too: Cherrix was charged with CAPITAL MURDER, forcible sodomy and use of a firearm — it is on this sheet for the corpus delicti rule, which is general.
Maughs v. City of Charlottesville 181 Va. 117, 120, 23 S.E.2d 784, 786, Va., 1943
The source Cherrix cites for the definition itself: the corpus delicti is THE FACT THAT THE CRIME CHARGED HAS BEEN ACTUALLY PERPETRATED, and the Commonwealth must prove it in every criminal prosecution.
Practical value: Worth citing when the defence tries to expand corpus delicti into a requirement that the corroboration prove the defendant did it. It is about the crime, not the criminal.
Jackson v. Commonwealth 255 Va. 625, 646, 499 S.E.2d 538, 551, Va., 1998
The slight-corroboration rule as Cherrix quotes it: if the accused has FULLY CONFESSED, ONLY SLIGHT CORROBORATION of the confession is required to establish corpus delicti beyond a reasonable doubt.
Practical value: ⚠️ This entry REPLACES a "Jefferson v. Commonwealth, Va. App. (various)" entry that carried no citation and could not be verified as written. The proposition Jefferson was offered for — that the corroborating evidence need not itself be sufficient to convict — is carried by Watkins, Clozza and this case.
Campbell v. Commonwealth 194 Va. 825, 833-34, 75 S.E.2d 468, 473-74, Va., 1953
The authority Watkins cites for the LIMIT on what must be corroborated: the requirement reaches the facts constituting the corpus delicti, NOT all the contents of the confession and NOT all the elements of the crime.
Practical value: The answer to a motion to strike that lists each element and demands independent proof of each. That is not the rule.
Clozza v. Commonwealth 228 Va. 124, 133, 321 S.E.2d 273, 279, Va., 1984
The authority Watkins cites for the SLIGHT-CORROBORATION standard following a full confession.
Practical value: ⚠️ READ THE CAPTION: Clozza is a CAPITAL MURDER case (cert. denied, 469 U.S. 1230). It is on this sheet for the corroboration standard, which is general.
Epperly v. Commonwealth 224 Va. 214, 229, 294 S.E.2d 882, 891, Va., 1982
"[C]orroborative facts supporting the corpus delicti may be furnished by CIRCUMSTANTIAL EVIDENCE AS READILY AS BY DIRECT EVIDENCE."
Practical value: The case that makes the no-body prosecution possible, and it earns its place twice over: it is also on the ARSON sheet for the proposition that circumstantial evidence "is not an inferior species of evidence" and is "entitled to the same weight". The two holdings work together — corroboration may be circumstantial, and circumstantial proof is not second class.
Missouri v. Seibert 542 U.S. 600, U.S. (plurality), 2004
⚠️ A PLURALITY. Justice Souter "announced the judgment of the Court and delivered an opinion, in which STEVENS, GINSBURG, and BREYER, JJ." joined — four Justices. JUSTICE KENNEDY CONCURRED IN THE JUDGMENT on narrower grounds, which makes his the controlling opinion in most courts under Marks. KENNEDY'S TEST: where "a DELIBERATE two-step strategy has been used, postwarning statements that are RELATED TO THE SUBSTANCE of prewarning statements MUST BE EXCLUDED UNLESS CURATIVE MEASURES ARE TAKEN before the postwarning statement is made." The plurality's own test is different — whether the "relevant facts . . . objective measure reveal a police strategy adapted to undermine the Miranda warnings."
Practical value: ⚠️ THE SHEET USED TO STATE THIS FLATLY AS A HOLDING. It is not one, and the difference is operational. Under Kennedy the question is whether the two-step was DELIBERATE, and — the part worth knowing — CURATIVE MEASURES CAN SAVE THE SECOND STATEMENT. A substantial break in time and circumstances, or an express explanation that the earlier statement is likely inadmissible, is the argument.
Schneckloth v. Bustamonte 412 U.S. 218, U.S., 1973
Voluntariness is judged on the TOTALITY OF THE CIRCUMSTANCES: "account must be taken of SUBTLY COERCIVE POLICE QUESTIONS, as well as the POSSIBLY VULNERABLE SUBJECTIVE STATE of the person who consents." Knowledge of the right to refuse is one factor, not a prerequisite.
Practical value: ⚠️ READ THE CAPTION BEFORE CITING IT ON THIS SHEET. Schneckloth is a FOURTH AMENDMENT CONSENT-TO-SEARCH case — the question was whether a consent to search was "constitutionally valid as a relinquishment of his Fourth Amendment rights", not whether a confession was voluntary. It borrows its totality test FROM the confession line, so it reads across, but cite it for the test and not as a confession holding. The sheet formerly listed it flatly under voluntariness.
Berghuis v. Thompkins 560 U.S. 370, U.S., 2010
TWO HOLDINGS. INVOCATION: an accused who wants to invoke the right to remain silent must do so UNAMBIGUOUSLY — "Thompkins DID NOT SAY that he wanted to remain silent or that he did not want to talk with the police," and "[h]ad [he] said" either, "he would have invoked his right to end the questioning." WAIVER: "Where the prosecution shows that A MIRANDA WARNING WAS GIVEN AND THAT IT WAS UNDERSTOOD by the accused, an accused's UNCOERCED STATEMENT ESTABLISHES AN IMPLIED WAIVER of the right to remain silent."
Practical value: The two things to prove are narrow and provable: the warning was given, and it was understood. Get the understanding on the recording — an express "do you understand?" and an audible answer is what carries the implied-waiver argument.
Davis v. United States 512 U.S. 452, 458-59, U.S., 1994
The source of the unambiguous-invocation requirement, which Berghuis extended from the right to counsel to the right to silence. The requirement "results in an OBJECTIVE INQUIRY that 'avoid[s] difficulties of proof and . . . provide[s] guidance to officers' on how to proceed IN THE FACE OF AMBIGUITY."
Practical value: Note the reason the rule exists — it is there to tell the officer what to do when the words are unclear, which is why the answer is that he may keep going. Clarifying questions are permitted but not required.
Berkemer v. McCarty 468 U.S. 420, U.S., 1984
"[P]ersons temporarily detained pursuant to such stops are NOT 'IN CUSTODY' for the purposes of Miranda", because the atmosphere of an ordinary traffic stop "is substantially less 'POLICE DOMINATED'" than stationhouse interrogation. BUT THE SECOND HALF MATTERS AS MUCH: "If a motorist who has been detained pursuant to a traffic stop THEREAFTER IS SUBJECTED TO TREATMENT THAT RENDERS HIM 'IN CUSTODY' FOR PRACTICAL PURPOSES, he will be entitled to THE FULL PANOPLY OF PROTECTIONS prescribed by Miranda."
Practical value: ⚠️ The sheet used to give only the first half, which is the half that loses statements. A roadside stop can BECOME custody — being handcuffed, put in the back of a cruiser, or held while others are searched. Fix the moment custody began and warn before the next question.
Colorado v. Connelly 479 U.S. 157, U.S., 1986
"[C]OERCIVE POLICE ACTIVITY IS A NECESSARY PREDICATE to the finding that a confession is not 'voluntary' within the meaning of the Due Process Clause of the Fourteenth Amendment."
Practical value: A NECESSARY predicate, not a sufficient one — the defence must point to something the police did. Mental illness, intoxication and low IQ go to the totality once coercion is on the table; they do not get there on their own.
Miranda v. Arizona 384 U.S. 436, 445-58, U.S., 1966
The concern the whole doctrine is built to answer, in the form Berkemer quotes it: the danger that a person questioned in a "POLICE DOMINATED" atmosphere will be induced "to speak WHERE HE WOULD NOT OTHERWISE DO SO FREELY."
Practical value: Useful because it names the test the custody cases actually apply. Berkemer decides the traffic stop by measuring it against police domination, not by counting minutes. ⚠️ PROVENANCE IS THINNER HERE THAN ELSEWHERE ON THIS SHEET — see the verified field. This entry states only what two later opinions print, not a reading of Miranda itself.
⚠️ TWO KEY CASES ENTRIES WERE CORRECTED ON 2026-08-24 and three citation placeholders replaced. See the revision notes.
