The question of whether law enforcement can compel a person to unlock their cell phone has been the subject of legal debate and court rulings. While the Fourth Amendment allows law enforcement to search a device with a warrant, the Fifth Amendment grants individuals the right to remain silent, raising questions about whether unlocking a device constitutes compelled speech or self-incrimination. Courts have disagreed on this issue, with some finding that unlocking a device only communicates knowledge of the password, while others argue it implies control over the device and its contents. In recent cases, law enforcement has forced individuals to unlock their phones using facial recognition, thumbprints, and fingerprint identification, with courts ruling that these methods are permissible as they do not disclose knowledge. However, a California judge ruled that individuals have a right to privacy, preventing police from forcing the unlocking of a device using biometrics. As technology advances, the law is still catching up, creating uncertainty about the limits of law enforcement's powers in this area.

What You'll Learn
The Fifth Amendment and self-incrimination
The Fifth Amendment protects criminal defendants from having to testify if they may incriminate themselves through their testimony. The Fifth Amendment grants persons the "'right to remain silent'. This right is not limited to criminal defendants; any witness may "plead the Fifth" and refuse to answer if they believe their answer may incriminate them.
In the 1966 landmark case Miranda v. Arizona, the United States Supreme Court extended the Fifth Amendment protections to encompass any situation outside of the courtroom that involves the curtailment of personal freedom. This means that any time law enforcement takes a suspect into custody, they must make the suspect aware of their Miranda rights, which include the right to remain silent, the right to have an attorney present during questioning, and the right to have a government-appointed attorney if the suspect cannot afford one.
The Fifth Amendment also contains the Double Jeopardy Clause, which provides the right of defendants to be tried only once in federal court for the same offense. The Self-Incrimination Clause provides various protections against self-incrimination, including the right of an individual not to serve as a witness in a criminal case in which they are a defendant.
The Fifth Amendment right does not extend to an individual's voluntarily prepared business papers because the element of compulsion is lacking. The privilege against self-incrimination does not protect an individual from being suspended from membership in a non-governmental, self-regulatory organization (SRO), such as the New York Stock Exchange (NYSE), where the individual refuses to answer questions posed by the SRO.
The law is still catching up with technology when it comes to law enforcement unlocking cell phones. Courts have near-uniformly determined that requiring a person to unlock a device is compelled speech, which violates the Fifth Amendment. However, under the "foregone conclusion" doctrine, law enforcement can compel speech if they can independently prove that the person knows the password, controls the device, and controls the content of the device.
Additionally, police officers can force individuals to unlock their cell phones using facial recognition or fingerprint identification, as these are considered nontestimonial acts that do not disclose any knowledge. However, a California judge has ruled that individuals have a right to keep the contents of their phones private, and law enforcement cannot force individuals to unlock their phones using biometric recognition.

Warrants and the right to privacy
The question of whether law enforcement can have a company unlock a cell phone is a complex one and depends on various factors, including the method of unlocking and the jurisdiction.
In the United States, the Fifth Amendment protects individuals from being compelled to incriminate themselves. This has been interpreted to include the "right to remain silent" and the right to not be forced to perform a "testimonial act" that discloses the contents of one's mind. However, courts have differed in their interpretation of whether unlocking a device with a passcode or biometric data, such as a fingerprint or facial recognition, constitutes a testimonial act.
Some courts have held that unlocking a device with a passcode is a testimonial act, as it communicates knowledge of the password and control over the device and its contents. Therefore, law enforcement would need to independently establish that the individual knows the password, controls the device, and controls the content of the device to compel the unlocking of the device.
On the other hand, courts have generally held that unlocking a device with biometric data, such as a fingerprint or facial recognition, is not a testimonial act, as it does not disclose any knowledge beyond mere access to the device. In these cases, law enforcement can force individuals to unlock their devices with their fingerprints or facial recognition, as seen in the United States v. Jeremy Travis Payne case.
It is worth noting that the law is still catching up with technology, and there may be differences in how these cases are handled across jurisdictions. For example, a California judge has ruled that individuals have a right to keep the contents of their phones private and prevented police from forcing people to unlock their phones using biometric recognition.
To protect one's right to privacy, it is advisable to use a strong passcode or password on one's cell phone, as this provides more protection against forced unlocking by law enforcement compared to biometric unlocking methods.
In summary, while law enforcement may be able to compel the unlocking of cell phones in certain circumstances, the specific method of unlocking and the jurisdiction will play a crucial role in determining the legality of such actions. Individuals should be aware of their rights and understand the basic laws surrounding these situations.

Nontestimonial acts and biometrics
The Fifth Amendment of the U.S. Constitution protects individuals from self-incrimination, ensuring that people cannot be forced to provide evidence that could incriminate them. This protection extends to various forms of testimony and evidence, but its application to biometric data is a complex issue.
Biometric data, such as fingerprints and facial recognition, has been used by law enforcement to unlock individuals' cell phones. In 2018, a suspect in an FBI investigation was forced to unlock his phone with his face. This incident sparked a debate over the rights of individuals concerning biometric data access and law enforcement's use of technology in investigations.
The distinction between testimonial and nontestimonial acts is crucial in this discussion. Testimonial acts involve revealing personal knowledge or information, while nontestimonial acts do not. Providing a password or PIN is considered a testimonial act because it involves revealing knowledge that could incriminate the person. On the other hand, using a fingerprint or facial recognition is considered a nontestimonial act as it does not involve disclosing any knowledge but rather a physical characteristic.
Courts have been addressing cases involving biometric data, balancing law enforcement's needs with individual privacy rights. However, the legal landscape is evolving, and there is no consistent guidance from the Supreme Court on how to navigate this complex issue. Some courts have held that requiring biometric information is a testimonial act, while others have concluded that it is a nontestimonial act.
The method of locking a cell phone is essential. Police officers cannot force an individual to unlock their phone by a testimonial act that reveals the contents of their mind. However, they can be forced to unlock their phone by a nontestimonial act, such as using facial recognition or fingerprint identification.

Circuit splits and the Supreme Court
The question of whether law enforcement can compel a person to unlock their cell phone has resulted in a circuit split, with courts divided on how the Fifth Amendment applies to the act of unlocking a device. This circuit split increases the likelihood that the United States Supreme Court will issue a definitive ruling to resolve the conflicting interpretations.
The Fifth Amendment of the United States Constitution protects individuals from being compelled to act as a witness against themselves in a criminal case. Courts have generally agreed that requiring a person to unlock a device constitutes compelled speech under the Fifth Amendment. However, the "foregone conclusion" doctrine provides an exception to this protection. Under this doctrine, law enforcement can compel speech if the content of the speech is already independently known to them.
Courts have formed two distinct camps when interpreting what is communicated when a person is compelled to unlock a device. The first camp holds that unlocking a device only communicates knowledge of the password, and law enforcement can require unlocking if they can establish that the person knows the password. The second camp argues that unlocking a device implies not just knowledge of the password but also control of the device and its contents. Therefore, courts in this camp permit law enforcement to compel unlocking only if they can independently prove that the individual knows the password, controls the device, and controls the content of the device.
The Indiana Supreme Court, the highest state court in Indiana, has sided with the second camp, creating a split from other jurisdictions. This circuit split increases the chances that the United States Supreme Court will intervene to provide a definitive ruling on the correct interpretation of the law. The Supreme Court's role in resolving circuit splits is crucial to ensuring that individuals' rights under the United States Constitution are applied equally across the nation, regardless of location.
In the case of United States v. Jeremy Travis Payne, the 9th Circuit Court of Appeals ruled that the Fifth Amendment's protection against self-incrimination does not prohibit police officers from forcing a suspect to unlock a phone with a thumbprint scan. The court determined that this action was similar to fingerprinting an individual at a police station and did not violate the Fourth Amendment's protection against unreasonable search and seizure. This ruling, however, does not apply to all cases involving the use of biometrics to unlock electronic devices.
As technology advances, the law is still catching up and adapting to new challenges. The Supreme Court's intervention in this circuit split will provide much-needed clarity on the rights of individuals and the authority of law enforcement in the digital realm.

The law catching up with technology
The law is often playing catch-up with technology, and this is particularly true when it comes to law enforcement accessing locked cell phones. The Fifth Amendment states that:
> “No person shall be held to answer for a capital, or otherwise infamous crime, nor shall any person be subject for the same offence to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.”
This means that in a criminal case, a person cannot be forced to be a witness against themselves. However, this has become a grey area when it comes to unlocking cell phones, as the method of locking the phone can make the difference between being required to unlock it for law enforcement or not.
Courts have generally determined that requiring a person to unlock a device is compelled speech, and therefore violates the Fifth Amendment. However, under the "foregone conclusion" doctrine, law enforcement can compel speech if they can independently prove that the person knows the password, has control of the device, and controls the content of the device. This has been interpreted differently by different courts, with some finding that unlocking a device only communicates that the person knows the password, and others finding that it communicates more than this.
The distinction between testimonial and nontestimonial acts has also been used to determine whether law enforcement can force a person to unlock their phone. Nontestimonial acts, such as facial recognition or fingerprint identification, do not disclose any knowledge and so can be forced by law enforcement. However, testimonial acts that reveal the contents of a person's mind cannot be forced.
The law in this area is still evolving, with some courts ruling that law enforcement can physically make a person unlock their phone with their thumbprint, while others have ruled that people have a right to keep the contents of their phones private. As technology advances, it is important for individuals to know their rights and understand the basic laws surrounding these situations.
