569 S.W.3d 634
Tex. Crim. App.2019Background
- Decedent Annie Sims was murdered; investigators linked stolen credit-card uses to a 2012 Silver Toyota Highlander and identified Christian Vernon Sims (Appellant) as a suspect.
- Lamar County deputies requested Verizon to "ping" Appellant’s cell phone using an emergency disclosure form rather than obtaining a warrant; Verizon provided near–real-time CSLI that located the phone and led to Appellant’s arrest.
- Appellant moved to suppress the real-time location data, claiming violations of the Fourth Amendment, the federal Stored Communications Act (SCA), Texas Code Crim. Proc. art. 18.21, and Texas’s statutory exclusionary rule (art. 38.23(a)).
- Trial court denied suppression based on exigent-circumstances reasoning under art. 18.21; Appellant pleaded guilty but reserved the right to appeal the suppression ruling.
- Court of Appeals affirmed; Texas Court of Criminal Appeals granted discretionary review on two questions: (1) whether suppression is an available remedy for SCA or art. 18.21 violations, and (2) whether Appellant had a reasonable expectation of privacy in the real-time CSLI.
- The Court held suppression is unavailable for nonconstitutional SCA/art.18.21 violations (their exclusivity clauses prevail over the general art. 38.23(a)), and that under the case facts (less than ~3 hours of tracking, <5 pings), Appellant lacked a reasonable expectation of privacy in the real-time CSLI.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether statutory violations of the SCA or art.18.21 trigger suppression under art.38.23(a) | Sims: art.38.23(a)’s broad language requires suppression for any violation of federal or state law, including SCA/art.18.21 | State: SCA and art.18.21 contain exclusivity clauses—suppression is not an available remedy for nonconstitutional statutory violations | Exclusivity clauses in SCA and art.18.21 control as specific exceptions to general art.38.23(a); suppression unavailable for nonconstitutional statutory violations |
| Whether art.18.21’s remedies preclude art.38.23(a) | Sims: art.38.23(a) should prevail as the broader statute providing greater protection | State: apply general-vs-specific canon; later-enacted, specific statutory remedies prevail | Specific statutes (SCA/art.18.21) prevail as exceptions to art.38.23(a) for nonconstitutional violations |
| Whether accessing real-time CSLI via warrantless pinging is a Fourth Amendment search | Sims: real-time location data is private and should be protected; warrant required | State: exigent circumstances justified pinging; public movements not protected | Case-by-case Fourth Amendment inquiry; here, less than ~3 hours and few pings did not violate a reasonable expectation of privacy—no warrant remedy required |
| Applicability of third-party doctrine and Carpenter to real-time CSLI | Sims: third-party doctrine inapplicable; Carpenter protects CSLI generally | State: relied on Knotts/Smith principles to deny privacy; also argued exigency | Court: Carpenter discredits broad application of third-party doctrine and Knotts; but under facts (short-term, limited pings) no expectation of privacy was shown; Carpenter governs longer-term/higher-invasion scenarios |
