OPINION ON REHEARING EN BANC
Before CHAMBERS, BROWNING, DUNIWAY, ELY, HUFSTEDLER, WRIGHT, TRASK, CHOY, GOODWIN, WALLACE, SNEED and KENNEDY, Circuit Judges.
CHOY, Circuit Judge:The question presented to us on rehearing en banc is whether Almeida-Sanchez v. United States, 413 U.S. 266, 93 S.Ct. 2535, 37 L.Ed.2d 596 (1973), requires the suppression of evidence obtained in searches of private vehicles at permanent traffic checkpoints removed from the border or its functional equivalents, made by border patrol officers without consent or probable cause, after June 21, 1973, the date that Almeida-Sanchez was decided, and before May 9, 1974, when this court announced its decision in United States v. Bowen, 500 F.2d 960 (9th Cir. 1974), affirmed, 422 U.S. 916, 95 S.Ct. 2569, 45 L.Ed.2d 641 (1975). That such searches are unconstitutional is not at issue, for they were specifically so declared in United States v. Ortiz, 422 U.S. 891, 95 S.Ct. 2585, 45 L.Ed.2d 623 (1975), and previously had been so held by us in Bowen.1 The issue is essentially to what extent Ortiz should be applied retroactively to searches prior to our announcement in Bowen.
The facts of this case are stated in the opinion of a panel of this court reversing appellant’s conviction for possessing marihuana with intent to distribute in violation of 21 U.S.C. § 841(a)(1) (1970):
On September 20, 1973, Border Patrol agents at the San Clemente immigration checkpoint on interstate route 5, approximately 66 miles from the Mexican border, made a routine stop of a station wagon *121driven by appellant. The agents searched the station wagon and found 244 pounds of marihuana in the luggage well and spare tire well. No claim is made that the agents had a “founded suspicion” to justify stopping appellant’s vehicle . or probable cause to search the vehicle . ...
Appellant moved to suppress the marihuana. His motion was denied. He then reserved his right to renew the motion, waived jury trial, and proceeded to trial upon stipulated facts. He was convicted of possessing marihuana with intent to distribute in violation of 21 U.S.C. § 841(a)(1) (1970) (citations omitted).
United States v. Juarez-Rodriguez, 498 F.2d 7 (9th Cir. 1974).
The precedents surrounding this case are complicated. In Almeida-Sanehez the Supreme Court held unconstitutional a vehicle search by a roving patrol unit looking for illegal aliens based not on consent or probable cause but simply on the car’s being located in the general vicinity of the border. The following year we held in Bowen, upon en banc consideration, that Almeida-Sanchez applied as well to searches at fixed checkpoints, but also that Almeida-Sanehez should not be applied retroactively, thus ruling that evidence obtained in a 1971 search should not be excluded. Bound by Bowen’s holding that Almeida-Sanehez applied directly to fixed checkpoint searches and faced with a post-Almeida-Sanehez search, the panel that originally heard this case reversed appellant’s conviction and required that evidence obtained by the search be suppressed. Later, however, the Supreme Court vacated that Bowen holding, stating:
As the Court of Appeals correctly decided in this case that Almeida-Sanehez did not apply to a 1971 search, it should have refrained from considering whether our decision in that case applied to searches at checkpoints.
Bowen v. United States, 422 U.S. 916, 920-21, 95 S.Ct. 2569, 2573, 45 L.Ed.2d 641 (1975) (emphasis added). Hence, far from being controlling authority, this court’s “reaching out [in Bowen] to decide that Almeida-Sanehez applied to checkpoint searches in a case that did not require decision of the issue” was error. Id. at 920, 95 S.Ct. [2569] at 2573.
On the same day that it issued Bowen, the Court announced its own determination, in Ortiz, that fixed checkpoint vehicle searches without consent or probable cause were improper under the fourth amendment. Appellant argues that, though our statement to that effect in Bowen no longer applies, Ortiz makes it clear that Almeida-Sanehez is the controlling authority for invalidating the fixed checkpoint searches. Thus even if the Ortiz rule does not extend to pre-Almeida-Sanchez checkpoint searches, since Almeida-Sanchez itself is not retroactive—United States v. Bowen, 422 U.S. 916, 95 S.Ct. 2569, 45 L.Ed.2d 641 (1975); United States v. Peltier, 422 U.S. 531, 95 S.Ct. 2313, 45 L.Ed.2d 374 (1975)—appellant contends that it should apply to all such searches after Almeida-Sanchez.
In Ortiz the Court stated, 422 U.S. at 896-97, 95 S.Ct. at 2588:
We are not persuaded that the differences between roving patrols and traffic checkpoints justify dispensing in this case with the safeguards we required in Almeida-Sanehez. We therefore follow that decision and hold that at traffic checkpoints removed from the border and its functional equivalents, officers may not search private vehicles without consent or probable cause.
Contrary to appellant, we believe that the Supreme Court’s language in Ortiz does not indicate that the Court at any time previously had ruled on checkpoint searches, or had even implied that Almeida-Sanehez itself, and by its terms, held checkpoint searches invalid. Ortiz does not state that Almeida-Sanehez decided the question, but that the Supreme Court follows the principle in Almeida-Sanehez and, for the first time, “holds” that the rule of Almeida-Sanchez applies to traffic checkpoints removed from the border and its functional equivalents. True, Mr. Justice Powell noted in his majority opinion that the Court would at *122that time follow Almeida-Sanchez; but nowhere did he suggest that Almeida-Sanchez itself established the illegality of searches at fixed checkpoints. Had Mr. Justice Powell thought that the issue had been decided in Almeida-Sanchez, he could have readily said so. Instead, he stated the Supreme Court would “follow that decision,” and then he “holds” that such search was unlawful.
This interpretation is also supported, we believe, by the language used by Mr. Justice Powell in writing for the court in Bowen, filed on the same day he filed Ortiz:
We hold today in United States v. Ortiz, ante, p. 891, [95 S.Ct. 2585, 45 L.Ed.2d 641], that the Fourth Amendment, as interpreted in Almeida-Sanchez, forbids searching cars at traffic checkpoints in the absence of consent or probable cause.
422 U.S. at 918, 95 S.Ct. at 2571 (emphasis added). To this court, the Supreme Court’s language above can only mean one thing— Almeida-Sanchez did not hold that its principles applied to searches at traffic checkpoints, but Ortiz did so hold.
Given that the principle of Almeida-Sanchez has since been held to apply to checkpoint searches, the question arises whether evidence from searches conducted after June 21, 1973, but before our opinion in Bowen, on May 9, 1974, should be suppressed. In United States v. Peltier, 422 U.S. 531, 95 S.Ct. 2313, 45 L.Ed.2d 374 (1975), the Court observed:
If the purpose of the exclusionary rule is to deter unlawful police conduct then evidence obtained from a search should be suppressed only if it can be said that the law enforcement officer had knowledge, or may properly be charged with knowledge, that the search was unconstitutional under the Fourth Amendment.
Id. at 542, 95 S.Ct. at 2320.
Contrary to the dissent herein, we believe it is clear that prior to this court’s decision in Bowen, there was no holding which gave law enforcement agencies adequate notice of the unconstitutionality of fixed checkpoint searches conducted without probable cause or consent. The Department of Justice and state law enforcement agencies were not aware that checkpoint searches were constitutionally impermissible. The dissent claims, “The Government was a party to dozens of cases in which the point was made.” Infra at 124. But the dissent does not claim that any one case held, or even implied, that such searches were unconstitutional. Our own sharp division on that issue in Bowen —seven to six — reflects the closeness of the question and the lack of any clear holding or implication prior to the announcement in Bowen itself. We emphasize that Almeida-Sanchez itself only concerned such searches conducted pursuant to roving patrols. That holding did not affect checkpoint searches. It is therefore clear that neither Almeida-Sanchez, nor, for that matter, any other decision, gave the Government, district court judges, or circuit court judges adequate notice that checkpoint searches were prohibited.2
Not until Ortiz and Bowen announced a new constitutional doctrine as to fixed checkpoint searches, and broadened the existing exclusionary rule (as Almeida-Sanchez had previously done as to roving patrols), were there any guidelines for arresting officers to follow. We are thus confronted with a retroactivity question which is similar to the one which the Supreme Court confronted in Peltier. Because the *123Government seized the evidence here reasonably, in good faith, and without knowledge that the search was unconstitutional, we hold that evidence from fixed checkpoint searches without consent or probable cause conducted prior to our holding in Bowen on May 9, 1974, need not be suppressed.
Since the court is evenly divided on this rehearing en banc, the district court’s judgment of conviction stands.
IT IS SO ORDERED.
. As discussed below, that portion of our decision in Bowen was later disavowed by the Supreme Court in affirming our judgment, at 422 U.S. 916, 95 S.Ct. 2569, 45 L.Ed.2d 641 (1975).
. We note that in another opinion filed on the same day as Ortiz and Bowen, the Court declined to apply the same probable cause standard to another variation of the roving patrol searches of Almeida-Sanchez. In United States v. Brignoni-Ponce, 422 U.S. 873, 95 S.Ct. 2574, 45 L.Ed.2d 607 (1975), the Court held that a roving patrol could stop a motorist near the border for a brief inquiry into his residential status based upon the lesser standard of reasonable suspicion.
Most recently, in United States v. MartinezFuerte, 428 U.S. 543, 96 S.Ct. 3074, 49 L.Ed.2d 1116 (1976), the Court held that routine stops for brief questioning could be made at reasonably located fixed checkpoints without any individualized suspicion that the particular vehicle contains illegal aliens.
As it was for Ortiz, Almeida-Sanchez was certainly a relevant precedent for these decisions, but it did not serve to dictate the result.
