INTRODUCTION
In this case we are asked to revisit our decision in
People v Goff,
I. FACTS
Verneida Mitchell was charged with the second-degree murder 1 of Richard Williams. A warrant to search defendant’s house was secured by Sergeant Lloyd Clemons of the Detroit Police Department. A subsequеnt search revealed evidence indicating that the murder took place in defendant’s home.
Defendant moved to suppress thе evidence, contending that the search warrant was invalid under Goff because the affiant, Sergeant Lloyd Clemons, did not sign the affidavit that supported issuance of the search warrant. The trial court, relying on Goff, granted defendant’s motion to suppress the evidence.
The Court of Appeals granted the prosecutor’s appliсation for leave to appeal, reversed the decision of the trial court, and remanded the case to the trial court for an evidentiary hearing to determine whether there was an adequate basis for issuance of the search warrant. 2
In lieu of granting lеave to appeal, we remanded this case to the Detroit Recorder’s Court for an evidentiary hearing to determine whethеr the affidavit in support of the search warrant was made on oath to a magistrate. We retained jurisdiction. 3
At the hearing held in Detroit Recorder’s Court, Sergeant Lloyd Clemons testified that he was the investigator in charge of this case and the affiant on the warrant to search defendant’s home. He *367 further testified that on March 11, 1983, after preparing the search warrant and affidavit, he took the documents tо Judge George Crockett, III, of the Detroit Recorder’s Court. He met Judge Crockett on the first floor of the Frank Murphy Hall of Justice and prеsented the search warrant to him. Judge Crockett administered an oath to Sergeant Clemons, having him attest to the information submitted in support of the search warrant.
Judge Crockett testified at the hearing that on March 11, 1983, he was assigned magistrate duties in Detroit Recorder’s Court. These duties required him to authorize search warrants. He testified that the signature on the warrant that authorized the search of defendant’s hоme was his, but that he had no independent recollection of authorizing that specific search warrant. He testified that it was his habit, from whiсh he never deviated, to have the affiant attest to the facts supporting the search warrant prior to authorizing it.
The trial court found that the affidavit in support of the search warrant was made under oath to a magistrate.
We granted defendant’s application for leave to appeal. 4
II. DISCUSSION
The United States and Michigan Constitutions require search warrants to be based upon probable cause, supported by oath or affirmation. US Const, Am IV; Const 1963, art 1, § 11. The Legislature has enаcted MCL 780.651; MSA 28.1259(1) to implement this constitutional mandate. This statute provides:
*368 When an affidavit is made on oath to a magistrate authorized to issuе warrants in criminal cases and when the affidavit establishes the grounds for issuing a warrant pursuant to this act, the magistrate, if he is satisfied that there is reasonable or probable cause therefor, shall issue a warrant to search the house, building or other location or plаce where the property or thing which is to be searched for and seized is situated.
The statute requires that an affidavit be made on oath to a magistrate. In Goff, supra, while recognizing that neither the statute nor Michigan case law explicitly requires the affiant’s signature on the affidаvit, we held that an affidavit in support of a search warrant must be signed by the affiant, or the search warrant is invalid. We rested our decision on policy grounds. 5 Goff, supra, 413-414.
However, rather than invalidating the search warrant in Goff, we remanded that case to the Recorder’s Court for further proceedings to determine whether the affidavit was mаde on oath to a magistrate. Goff, supra, 414. Our holding, invalidating search warrants based on unsigned affidavits, was limited to search warrants issued after the datе of that opinion. Goff, supra, 413-414.
We are now persuaded that a search warrant should not necessarily be invalidated by the failure of the affiаnt to affix his signature to the affidavit. The Michigan and United States Constitutions require that search warrants must be supported by oath or affirmation. MCL 780.651; MSA *369 28.1259(1), quoted abovе, requires the affidavit to be made on oath to a magistrate. The requirement of an oath or affirmation is designed to guarantee thаt the information submitted to support a finding of probable cause to issue a search warrant is sworn to by the affiant. 6 An affidavit given under oаth assures that the information submitted in support of the search warrant is sworn to by the affiant. Therefore, we hold that a search warrant bаsed upon an unsigned affidavit is presumed invalid, and any evidence seized pursuant to that search warrant must be excluded. However, the prosecution may rebut this presumption of invalidity by a showing that the affidavit was made on oath to a magistrate.
In this case, the trial court, аfter an evidentiary hearing, found that the affidavit was made on oath to a magistrate. Findings of fact by a trial court will not be set aside on appeal unless clearly erroneous. MCR 2.613(C). We do not find that the trial court was clearly erroneous in finding that the affidavit was made on оath to a magistrate. Therefore, the search warrant was valid, and the evidence seized pursuant to the warrant is admissible in defendаnt’s trial. The trial court’s order suppressing the evidence seized pursuant to the search warrant is reversed.
Although the Court of Appeаls panel in this case correctly anticipated our holding, we disapprove of the manner in which the panel indicated its disagreement with
Goff.
An elemental tenet of our jurisprudence, stare decisis, provides that a decision of the majority of justices of this Court is binding upon lower courts. See

People v Mitchell,
People v Mitchell,
People v Mitchell,
Assuring that affidavits are sworn and that police departments carefully comply with warrant requirements, as well as considerations of the efficient administration of justice, supports requiring an affiant to sign the affidavit. An unsigned affidavit wastеs scarce judicial resources by requiring an evidentiary hearing on the question whether the affidavit was made on oath to a magistrate. These considerations apply with equal force now as they did then.
