Rejecting a dissenting justice who said the nature of trash has changed, the Minnesota Supreme Court today ruled that you should have no expectation of privacy when putting your trash at the curb, saying the Minnesota Constitution does not provide greater privacy protection of trash than the U.S. Constitution.

The court ruled in the case of David McMurray of Hutchinson, whose trash was searched by police after their daughter told a mandated reporter she saw her mother with a pipe used for drugs.

They found several plastic bags containing white residue, which later tested positive as methamphetamine, drug paraphernalia and documents belonging to McMurray and his wife. Armed with a search warrant for the home, police discovered meth inside.

McMurray argues that the search of the trash violates the Minnesota Constitution, which says “The right of the people to be secure in their persons, houses, papers, and effects against unreasonable searches and seizures shall not be violated; and no warrant shall issue but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched and the person or things to be seized.”

Today, the Supreme Court upheld a Court of Appeals ruling denying the search was unconstitutional. It said the U.S. Supreme Court has ruled consistently that trash is public. But the Minnesota court considered whether Minnesota’s Constitution affords greater protection than the U.S. Constitution on the matter.

It doesn’t, Justice Wilhelmina Wright wrote in today’s opinion (pdf).

“Garbage is placed at the curb with the expectation that a third-party trash collector will take it, and the trash collector could sort through the garbage or permit others to do so,” she said. “It is not reasonable to expect the contents of garbage bags placed on the side of a public street for collection to remain private.”

But Justice David Lillehaug disagreed and says the Minnesota Constitution affords greater privacy rights than its U.S. counterpart. “Our basic rights and liberties are at risk if government can seize and search Minnesotans’ household waste without a search warrant and, apparently, without even a reasonable articulable suspicion of wrongdoing,” he wrote in a dissent.

Household waste contains a great deal of personal information that most of us expect will remain private. As the New Jersey Supreme Court put it, “Clues to people’s most private traits and affairs can be found in their garbage.” One who examines garbage carefully can learn about the household members’ physical and mental health, sexual activities, financial status, consumer preferences, political affiliations, and personal relationships. At different times, people dispose of drug bottles, birth control devices, sanitary products, printouts of emails, check registers, photos, and whatever they have recently read or eaten. It is the very privacy—the intimacy—of this personal information that makes it of great interest to others, ranging from law enforcement officers to private investigators to neighborhood snoops. Until a person’s garbage “ ‘ha[s] lost its identity and meaning by becoming part of a large conglomeration of trash elsewhere,’ ” we “ ‘can readily ascribe many reasons why residents would not want their . . . telltale refuse and trash to be examined by neighbors or others.’ ”

Lillehaug said the nature of our trash has changed and ” so has government’s ability to analyze it. Investigative tools are much more sophisticated and their probing capacity now extends well beyond the curtilage,” he said.

And, besides, he said, there’s no alternative for most people than putting it by the side of the road because “burying it on the back forty is no longer a viable option.”

Justice Wright was unmoved by what she described as Lillehaug’s assertion that “this is not your grandfather’s garbage.”
