Police received an unverified tip that marijuana was being grown in Jardines' home. About a month later, detectives approached his home with a trained drug-sniffing dog, brought the dog onto the front porch, and allowed it to sniff around the base of the front door until it alerted. Based on what was learned at the home, police obtained a warrant, searched the residence, and found marijuana plants. Jardines argued that the canine investigation on the porch was an unconstitutional search.
Issue
Whether using a trained drug-sniffing dog on a homeowner's front porch to investigate the contents of the home is a search within the meaning of the Fourth Amendment.
Rule
When officers physically enter and occupy the home's curtilage to gather information, and do so for conduct not explicitly or implicitly permitted by the homeowner, they conduct a Fourth Amendment search. The customary implied license to approach a home permits a visitor to approach by the front path, knock promptly, wait briefly, and then leave, but it does not permit entry onto the curtilage to conduct a search.

One of 10 multiple-choice questions for this case. Pick an answer to see why.
In Columbus, Ohio, officers investigating an anonymous drug tip walked up Nina Patel's front path to her porch with a trained narcotics dog. Without knocking, the handler let the dog sniff around the front door seam and porch columns until it alerted to odors coming from inside the house.
Under the majority's rule, was the officers' conduct a Fourth Amendment search?
Explanation. Yes. The front porch is part of the home's curtilage, which the majority treated as part of the home itself. Although visitors may ordinarily approach by the front path, knock promptly, wait briefly, and leave, that implied license is limited by purpose as well as place. Bringing a trained police dog onto the porch to explore for incriminating evidence is an unlicensed physical intrusion to gather information, so it is a search.
