"Instead of adhering to the warrant requirement," Ginsburg wrote, "today's decision tells the police they may dodge it, nevermind ample time to secure the approval of a neutral magistrate." Tuesday's ruling, she added, "shrinks to petite size our holding in Georgia v. Randolph."

Georgia v. Randolph was a similar case the Supreme Court addressed in 2006, in which a domestic violence suspect would not allow police to enter his home, though his wife did offer police consent. The police ultimately entered the home. The Court ruled in the case that the man's refusal while being present in the home should have kept authorities from entering.

"A physically present inhabitant's express refusal of consent to a police search [of his home] is dispositive as to him, regardless of the consent of a fellow occupant," the majority ruled in that case.
