People v. Sneed, 2023 IL 127968

Background

Keiron Sneed was charged with two counts of forgery after two forged Dairy Queen paychecks payable to him were cashed via mobile deposit; police seized a phone from Sneed at arrest.
Officers obtained a warrant to search Sneed’s phone, but the phone was passcode‑protected and Sneed refused to provide the passcode.
The State moved to compel Sneed either to provide the passcode or to enter it into the phone so officers could execute the warrant; the trial court denied the motion on Fifth Amendment grounds and rejected the State’s reliance on the foregone‑conclusion exception.
The State filed a certificate of substantial impairment and appealed; the appellate court reversed, holding passcode entry was nontestimonial (and alternatively that the foregone‑conclusion exception applied).
The Illinois Supreme Court affirmed the appellate court’s judgment (on different grounds): it held entering a passcode is testimonial but the foregone‑conclusion exception applies when focused on the passcode itself (not the phone’s contents), and it found the State met the reasonable‑particularity burden.

Issues

Issue	State's Argument	Sneed's Argument	Held
Appealability under Ill. S. Ct. R. 604(a)(1)	The trial court’s denial effectively quashed the warrant and suppressed evidence; prosecutor’s certificate shows substantial impairment.	The order only limited the means to execute the warrant and did not suppress evidence or quash the warrant.	Court: appealable — denial annulled the warrant’s requirement to unlock the phone and suppressed evidence; prosecutor’s good‑faith certificate accepted.
Whether entering the passcode is testimonial	(initially argued non‑testimonial; conceded on appeal) any testimonial aspect is limited to ability to unlock the phone.	Entering the passcode is a testimonial act that delves into the contents of the mind and reveals possession/control of files.	Court: entering the passcode is testimonial to the extent it implicitly asserts ability to unlock the phone (existence, possession/control, authenticity).
Whether the foregone‑conclusion doctrine applies and where focus lies	Foregone‑conclusion applies to the passcode itself (not the phone contents); State can show the passcode’s existence, control, and authenticity with reasonable particularity.	Foregone‑conclusion should focus on phone contents; modern phones hold massive data so the exception should not swallow the privilege.	Court: foregone‑conclusion doctrine applies here; proper focus is the passcode (Spicer overruled).
Whether State met reasonable‑particularity to invoke foregone conclusion	The State knew the phone was passcode‑protected, it was seized from Sneed, Sneed identified the phone number on bond sheet, and a valid passcode is self‑authenticating.	Authenticity can't be shown until the passcode is used; State’s knowledge of contents was speculative.	Court: State met the test — passcode existed, was in Sneed’s possession/control, and is self‑authenticating when it unlocks the phone; exception applies.
