New York’s Appellate Division sent a clear message in People v Butler (July 3, 2025): officers cannot press a drug-sniffing dog against your clothing or skin unless they already have probable cause. The justices threw out a heroin conviction because a trooper let a canine push its snout into the defendant’s waistband during a traffic stop. That intrusion, the court ruled, crossed the line from a minimal sniff to a search so personal that it triggered the highest constitutional protections. If you ever face a roadside dog search, this decision can shape your options, your motions, and your leverage at every stage of the case.
The Decision Raises the Bar for Personal Privacy
The court compared a quick sniff around a car’s exterior with a dog’s nose pressed into intimate areas of a human body and concluded the two encounters are worlds apart. A vehicle sniff affects property; a body sniff affects dignity, autonomy, and personal security. Because the intrusion targets the “most private sphere,” the judges placed it in the top tier of the People v De Bour framework, which requires probable cause rather than mere reasonable suspicion. From now on, officers must point to concrete, verifiable facts suggesting you actually possess contraband before directing a dog toward your person.
