We are asked to determine, in this interlocutory appeal by the Commonwealth, whether the windowless rear interior of a cargo van, parked in a lot accessible to the public, is an area whose occupants may entertain a legitimate expectation of privacy. The judge ruled that an intrusion into such an area, made without probable cause and without either a warrant or exigent circumstances, was violative of both the Fourth Amendment to the United States Constitution and art. 14 of the Declaration of Rights of the Massachusetts Constitution. We affirm the motion judge’s order suppressing the evidence. Our narrative draws liberally on the judge’s undisputed findings, with only minor supplementation from the record.
On the afternoon of September 22, 1980, the manager of a clothing store in Canton telephoned the police in that town with a report of certain “suspicious activity” in a blue van parked in the lot at the rear of the store. 2 The officer who took the call dispatched one Officer James Brown to the scene. Brown testified he was told to check “[t]wo men inside a van acting suspicious.” Brown proceeded to the parking lot and observed the van. 3 He approached the van from the side. When he was within ten feet of it, he determined that the sliding cargo door on the passenger side was open approximately fifteen to eighteen inches, and that two people were in the rear of the van. From this vantage point he did not observe either contraband or criminal activity. *387 Nevertheless he walked up to the van and, in his words, “stuck [his] head inside.” Once partially inside the van, he observed the defendants, both of whom he knew. Both men were apparently engaged in cutting and bagging portions of a brown substance, later shown to be hashish, contained in a clear plastic sandwich bag. Officer Brown seized this bag. At that point another officer arrived, and the two men were ordered from the van owned by the defendant Collins. The officers then reentered the van and seized other drugs and paraphernalia. The defendants were charged with possession, with intent to distribute, of a class G controlled substance (G. L. c. 94C, § 31), and with conspiracy to violate G. L. c. 94C, § 32.
Our initial task is to characterize properly Officer Brown’s entry of the van. In arguing that the judge applied an erroneous legal standard by requiring probable cause to search, the Commonwealth urges on us the proposition that Officer Brown’s entry was not a search but rather a “lawful threshold inquiry.”

Adams
v.
Williams,
We must determine whether the defendants’ expectation of privacy in the interior of a windowless van, parked with its sliding door ajar in broad daylight and in a lot to which the public has access, is one which society could recognize as reasonable. See
Rakas
v.
Illinois,
Here, however, the officer did not discover the illegal activity until
after
his warrantless intrusion into the interior of the van. We are aware that a motor vehicle is generally afforded a lesser degree of Fourth Amendment protection than is other property. See
United States
v.
Chadwick,
*390
As we indicated earlier, the Commonwealth contends that the intrusion was a “lawful threshold inquiry,” thus apparently conceding that it was not supported by full probable cause.

The officer’s conduct here was so markedly different from that typically seen in “threshold inquiry” cases that we cannot credit this theory. Compare
Commonwealth
v.
Ferrara,
The Commonwealth challenges the “standing” of the defendant Podgurski, the passenger, to object to the search of the vehicle.
10
The argument as to the defendant Podgurski is based on recent opinions of the United States Supreme Court which have established new principles governing
*391
standing for Federal constitutional purposes. See
Rawlings
v.
Kentucky,
The United States Supreme Court has emphatically rejected the notion that concepts of property law should determine one’s ability to claim Fourth Amendment protec *392 tion. See Rawlings v. Kentucky, supra at 105; United States v. Salvucci, supra at 91-92; Rakas v. Illinois, supra at 143, 149-150 n.17. Instead, ownership of the property searched is but one factor to consider in the expectation-of-privacy analysis. In the circumstances of this case it is a factor of minimal significance. We think that Rakas should not be read to deprive a “mere” passenger of standing to object to a search where, but for his lack of a property interest in the vehicle, his situation is otherwise identical to that of the owner, who has the requisite standing. Accordingly, we affirm the order of the motion judge suppressing the evidence as to both defendants.
Order affirmed.
Notes
The officer who took the call testified that the manager said the two men were “cutting up something they shouldn’t have been cutting.” The judge did not accept this version of the citizen’s call.
The judge made no findings on the point, but it appears from the record that the vehicle was a cargo-type van with windows ip the driver and passenger doors, in addition to the front windshield.
The record before us does not reveal whether this contention was made to the motion judge. The defendants, however, make no claim that the Commonwealth has waived this point.
The expectation-of-privacy inquiry as to whether a search has occurred is preliminary to a determination whether applicable probable cause and warrant requirements have been followed. See
Commonwealth
v.
Ortiz,
In Rakas v. Illinois, supra at 148-149, the Court recognized, by negative implication, that there were circumstances where at least the owner of the vehicle could have a legitimate expectation of privacy in these areas.
According to uncontradicted testimony, it had windows only by the driver and passenger seats, plus the windshield. None of these would appear to offer a ready view of the rear interior from a vantage point on the street level. There is no finding that such a view might be possible.
In Commonwealth v. Ortiz, supra, we utilized the expectation-of-privacy analysis to distinguish between search and nonsearch situations. Id. at 351-353.
We note further that Officer Brown testified that it was not until
after
he had seized the plastic bag that he formed a belief that it contained hashish. Cf.
Sullivan
v.
District Court of Hampshire,
While contending that neither defendant had a reasonable expectation of privacy in the van, the Commonwealth does not challenge the “standing” of the defendant Collins, the owner of the van, to contest the search.
In the wake of these opinions, and particularly in light of the uncertainty engendered by the abolition of the “automatic standing” rule of
