Dollree Mapp, etc., Appellant v. Ohio
367 US 643, 6 Led 2d 1081, 81 S Ct 1684 [No. 236] (1961)

Facts

Cleveland Police Officers were given information that a person was hiding out in a home that was wanted for questioning in regard to a recent bombing. Police arrived at Appellant Mapp's home and demanded entrance. Defendant Mapp denied entry on advice of counsel, and the police, after advising headquarters, undertook surveillance. Some three hours later, the police again demanded entry. When Appellant Mapp did not come to the door, the police forcibly gained entry. There, they showed Appellant Mapp what was purportedly a warrant, and after arresting her, searched the premises. There they found lewd, leviscious book and pictures. Appellant Mapp was convicted in trial court of knowingly having these materials.

Question

Does the Weeks Exclusionary Rule (excluding evidence from trial obtained during unconstitutional searches and seizures) apply to states through the Due Process Clause of the Fourteenth Amendment?

Holding

The Court held that the Weeks Exclusionary Rule did apply to the states through the Due Process Clause of the Fourteenth Amendment.

Reasoning

In its decision, the Court mainly cites the cases of Weeks v. The United States, and Wolf v. Colorado. In Weeks, the court found that evidence obtained through unconstitutional searches and seizures was inadmissable in Federal Trials. The courts reasoning was that the people's right to be secure in their persons, houses and effects against unreasonable searches and seizures was a set of meaningless words if the Courts allowed evidence found in violation of the Fourth Amendment to be admitted in trial. In Wolf, the Court held that the Fourth Amendment's guarantee was a right, "implicit in the concept of ordered liberty," as per Palko v. Connecticut, and thus included in the Due Process Clause of the Fourteenth Amendment. However, the court did not find that the Exclusionary Rule was so implicit, stating that states could find other ways to insure the guarantees of the Fourth Amendment.

In this case, the Court cites People v. Cahan in the California Supreme Court, which forced that state to follow the Weeks Rule, since other remedies have completely failed to secure the Fourth Amendment Guarantees. The Court essential argues that all other remedies have also, failed to guarantee the rights, and in fact cannot but fail.

The Court also reasons that without applying the Weeks Rule, the Court would grant the right, but withhold it's privileges, making it a useless jumble of words.

The Court finally reasoned that instituting the Weeks Rule in states was common sense not inconsistent with the Constitution. Without holding states accountable to the Exclusionary Rule, Federal Officers could literally go across the street to have the case prosecuted by a state prosecutor, even though, both Federal and State Prosecutors are subject to the same rule.
