The US Supreme Court has decided to review Florida v. Jardines, a case that addresses whether a dog sniff at the front door of a home is a search that requires probable cause. This case follows Illinois v. Caballes, a 2005 case in which the Court held that a dog sniff around a car during a routine traffic stop was not a search. The Florida Supreme Court ruled that Caballes was inapplicable in the case, and that a dog sniff in front of a home is a Fourth Amendment search. This case also implicates the government's use of "enhanced" investigative techniques that are designed to detect contraband. Because these techniques are imperfect and also allow the government to search for material that is not illegal, EPIC has argued that a Fourth Amendment probable cause standard should apply.
