Facts
- Police arrested Dennis Jones and seized a cell phone found on his person.
- Jones was indicted on charges including trafficking a person for sexual servitude and deriving support from the earnings of a prostitute.
- The Commonwealth obtained a search warrant to search the phone for evidence but could not execute it because the phone was encrypted and required a password.
- The Commonwealth moved in Superior Court for an order compelling Jones to enter the phone’s password to permit execution of the warrant.
- The motion judge denied the request, concluding the Commonwealth had not shown that Jones’s knowledge of the password was a “foregone conclusion” under prior Massachusetts precedent.
- The Commonwealth filed a renewed motion with additional factual proffers; the judge again denied relief, partly reasoning the new information should not be considered and, regardless, the standard still was not met.
- The Commonwealth sought interlocutory review, and the Supreme Judicial Court considered whether compelled entry of the password violated protections against self-incrimination and what burden of proof applied.
Issues
- Whether ordering a defendant to enter a password to decrypt a seized cell phone, to enable execution of a valid search warrant, violates the Fifth Amendment or article 12 privilege against self-incrimination.
- Whether the “foregone conclusion” doctrine applies to compelled decryption by requiring the Commonwealth to show the defendant knows the password.
- What burden of proof the Commonwealth must satisfy to establish the foregone-conclusion showing in this context.
Decision
- The Supreme Judicial Court reversed the denial of the Commonwealth’s renewed motion to compel.
- The court held that compelling Jones to enter the password did not violate the Fifth Amendment or article 12 because his knowledge of the password was a foregone conclusion on the record presented.
- The court required the Commonwealth to prove beyond a reasonable doubt that the defendant knows the password before compulsion is permissible under the foregone-conclusion doctrine.
- The case was remanded for entry of an order compelling Jones to enter the password into the phone.
Legal Principles
- The privilege against self-incrimination protects against compelled testimonial communications; an act can be testimonial if it implicitly communicates facts derived from the person’s mind.
- Compelled decryption can be testimonial to the extent it implicitly asserts the defendant’s knowledge of the password and ability to access the device.
- Under the foregone-conclusion doctrine, compulsion is permitted when the government already knows, to the required certainty, the facts the compelled act would communicate; in the decryption setting, this includes the defendant’s knowledge of the password.
- In Massachusetts, the Commonwealth must prove beyond a reasonable doubt that the defendant knows the password to treat that knowledge as a foregone conclusion and to compel password entry consistent with the Fifth Amendment and article 12.
- A valid search warrant and a fact-specific showing of the defendant’s password knowledge are prerequisites to an order compelling decryption.
Conclusion
The Supreme Judicial Court permitted compelled entry of a phone password to execute a lawful warrant, but only where the Commonwealth proves beyond a reasonable doubt that the defendant knows the password, making the testimonial aspect of decryption a foregone conclusion under the Fifth Amendment and article 12.
