 Twenty-four U.S. States, the federal government, and two U.S. territories filed briefs in support of Florida as amici curiae.Oral argument in this case – and that of another dog sniff case, "Florida v. Jardines" – was heard on October 31, 2012.The Court unanimously held that if a bona fide organization has certified a dog after testing his reliability in a controlled setting, or if the dog has recently and successfully completed a training program that evaluated his proficiency, a court can presume (subject to any conflicting evidence offered) that the dog's alert provides probable cause to search, using a "totality-of-the-circumstances" approach.
