Damon Jerome Richardson, Appellant v. the State of Texas, Appellee

Summary

The Court vacated the Court of Appeals' categorical holding that a pen register is never a search under the Texas Constitution and remanded for further determination of whether the pen register constitutes a search and, if so, whether it is unreasonable without probable cause. The dissent argued that the appellant, as a pre‑trial detainee, had no reasonable expectation of privacy in the numbers dialed and therefore affirmed the lower court's denial of the suppression motion.
