Generally, a lawful search warrant may not be procured by the use of illegally obtained information. E.g., State v. Cuong Phu Le, 463 S.W.3d 872, 877 (Tex. Crim. App. 2015), cert. denied, 136 S. Ct. 819 (2016). As a matter of first impression, however, the Texas Court of Criminal Appeals held that the Texas good-faith exception to the statutory exclusionary rule applied to a search executed pursuant to a search warrant that was based on information obtained from an illegal drug sniff. McClintock v. State, No. PD-1641-15,2017 WL 1076289 (Tex. Crim. App. Mar. 22, 2017). The drug-sniffing dog had been brougcrimcht by police to the door of the defendant's upstairs residence, where the dog alerted police to the presence of drugs. This information was used as the basis for a search warrant for the residence, and there would have been no probable cause without the information. Execution of the warrant resulted in the seizure of marijuana. While the case was pending on appeal, the United States Supreme Court held that such dog sniffs constituted an unconstitutional search under the Fourth Amendment. See Florida v. Jardines, 133 S. Ct. 1409 (2013). Prior to the holding in Jardines, according to McClintock, it was not clear that the dog sniff used in McClintock was illegal.
