Question: What is a motion to suppress evidence?

Answer: A motion to suppress evidence is a written request to a Judge for an order excluding certain evidence from use at trial. In a criminal case, a motion to suppress evidence seeks to keep certain evidence from being used against the defendant.

The Amendments to the United States Constitution that are “fundamental to our concept of ordered liberty” have been applied to the States through the due process clause of the Fourteenth Amendment. Duncan v. Louisiana (1968). That includes the Fourth Amendment prohibition against unreasonable searches and seizures and the exclusionary rule requiring that evidenced gathered in violation of the Fourth Amendment cannot be used as evidence against a Defendant. The Ohio Constitution also contains a protection against unreasonable search and seizure. See, Article I, § 14 OH Const.

The exclusionary rule is a judicial remedy for violations of constitutional rights of the public by those investigating crimes and prosecuting criminals. Other remedies include civil lawsuits and criminal suits of individual law enforcement officers. The United States Supreme Court has said that the only justification for the exclusionary rule is to deter police misconduct. The exclusionary rule gives the judiciary the power to suppress (or exclude) illegally obtained evidence. Judges can apply the exclusionary rule to current cases without being forced to rely on other branches of government to enforce individual constitutional rights.

The exclusionary rule was created by Judges and initially applied only to the federal government. The United States Supreme Court first decided that the Fourth Amendment would prohibit the use of evidence secured through an illegal search and seizure in Weeks v. US (1914). Police entered the home of Fremont Weeks and sized papers that were used to convict him of transporting lottery tickets through the mail. The search was done without a warrant. The United States Supreme Court found that the removal of the documents directly violated Mr. Weeks’ rights; that allowing private documents to be seized and then held used as evidence would mean that the Fourth Amendment protection against that very action is of no value whatsoever. Mr. Weeks’ conviction was overturned.

The exclusionary rule was applied to the States through the Fourteenth Amendment in the United States Supreme Court case of Mapp v. Ohio (1961). In that case, Ms. Mapp was convicted of possessing obscene materials seized during an illegal warrantless search of her home for a fugitive. Ms. Mapp appealed her conviction on First Amendment grounds, which were brushed aside by the United States Supreme Court when it declared “all evidence obtained by searches and seizures in violation of the Constitution is…inadmissible in a State court.” The Mapp decision applied the requirement of excluding illegally obtained evidence to all levels of government.

The exclusionary rule has been limited by the deterrence theory (in short, that there must be something to deter in order for something to be excluded), the good faith exception (relying on an improperly issued warrant is not something to deter); and the independent source and inevitable discovery doctrines. More on those limits to the exclusionary rule another day!
