AFTER REMAND
MICHAEL J. KELLY, P.J.
This case is again before this Court following a remand to the trial court to determine whether evidence seized pursuant to a federal search warrant was obtained through the joint activity of state and federal officers. People v Pipok, unpublished opinion per curiam of the Court of Appeals, decided March 7, 1991 (Docket No. 126052). The trial court's supplemental opinion was entered on stipulated facts on April 19, 1991.
*671 In remanding, this Court held that when evidence challenged in a state prosecution is obtained in a search involving the joint activity of state and federal officers, the search is scrutinized under state standards. On remand, the trial court found that the search in this case did involve the joint activity of state and federal officers. We agree with the trial court's finding. The next inquiry is whether the search was valid under Michigan law. Defendants argue that the warrant was invalid and that the trial court improperly denied defendants' motion to suppress the evidence seized during the search. Defendants' appeal is by leave granted.
It is uncontested that the search warrant in this case did not comply with MCL 780.654; MSA 28.1259(4), which, in relevant part, requires that a search warrant provide on its face or in an attached affidavit the grounds on which the warrant is issued. The search warrant in this case failed to state the grounds for probable cause and did not have a supporting affidavit attached. The warrant was issued pursuant to federal law, for which there is no state counterpart to the precise statutory provision at issue here. A copy of the affidavit used to support the warrant was made available to the defendants before their preliminary examinations.
Defendants contend that noncompliance with § 4 rendered the search warrant invalid and, as a result, the evidence seized pursuant to the warrant should be suppressed. In support of their position, defendants rely on the cases of People v Galnt, 235 Mich 646; 209 NW 915 (1926), People v Bules, 234 Mich 335; 207 NW 818 (1926), and People v Moten, 233 Mich 169; 206 NW 506 (1925).
Contrary to the law then in effect, 1917 PA 338, § 27, the search warrants challenged in Galnt, *672 Bules, and Moten failed to recite all the material facts alleged in the supporting affidavits. In each case the Supreme Court found the warrant invalid and suppressed the evidence seized pursuant thereto. The Court in Moten quoted with approval the following from United States v Kaplan, 286 F 963, 969-970 (D Ga, 1923):
"The commissioner or judge having become satisfied by proven facts `of the existence of the grounds of the application or that there is probable cause to believe their existence,' he must not only issue the warrant, but must state therein `the particular grounds or probable cause for its issue.' The mandate is clear. Why should there not be an exact compliance? Is not the protective purpose of congress most definite  that the proof should be in writing, that facts, and not opinions, should be relied on, that the judgment should be on the proven facts and that a record of such judgment should be recorded in the warrant, of which a copy should be furnished the accused?" [233 Mich 173-174. Citations omitted.]
The Moten Court thus concluded that the primary purpose for requiring that a warrant recite the material facts alleged in the affidavit was to make a record of the judgment of probable cause in order to assure that the determination was made on proven facts and not opinions. The Court found the recital to be an "essential requirement" of a valid warrant and held that evidence seized pursuant to a warrant lacking such a recital must be suppressed.
Since the court's decision in Moten, statutory law in this state has changed to permit a supporting affidavit to be attached to the warrant in place of stating the material facts, or grounds for issuance, on the warrant itself. Again, the provision is designed to guarantee that a record of probable *673 cause is established. The Legislature has apparently recognized that the affidavit alone is sufficient to establish a record of probable cause and that it is not necessary to transcribe the material facts from the affidavit onto the warrant.
In this case, there is an affidavit setting forth the facts on which the federal magistrate's determination of probable cause was based. Defendants do not argue that the affidavit was insufficient to establish probable cause, and they do not articulate any prejudice that resulted from the noncompliance with § 4. Furthermore, defendants were furnished copies of the affidavit before the preliminary examinations and had the opportunity at those hearings to challenge probable cause supporting the search warrant. We therefore conclude that the failure of the warrant to state the grounds for issuance or to have the supporting affidavit attached did not abrogate the purpose of the statute and that the error was one of procedure not requiring suppression of the evidence. See People v Myers, 163 Mich App 120; 413 NW2d 749 (1987); People v Tennon, 70 Mich App 447; 245 NW2d 756 (1976).
Affirmed.
