What was the outcome of the California vs. Greenwood case regarding the legality of warrantless searches and seizures of garbage left outside a person's home?

In the California vs. Greenwood case, the Supreme Court ruled that warrantless searches and seizures of garbage left outside a person's home are legal. This means that law enforcement can search through someone's trash without a warrant because there is no expectation of privacy once the garbage is placed outside for collection.
