What follows is an opinion from the Supreme Court of the United States. Your task is to determine the bases on which the Supreme Court rested its decision with regard to the legal provision that the Court considered in the case. Consider "judicial review (national level)" if the majority determined the constitutionality of some action taken by some unit or official of the federal government, including an interstate compact. Consider "judicial review (state level)" if the majority determined the constitutionality of some action taken by some unit or official of a state or local government. Consider "statutory construction" for cases where the majority interpret a federal statute, treaty, or court rule; if the Court interprets a federal statute governing the powers or jurisdiction of a federal court; if the Court construes a state law as incompatible with a federal law; or if an administrative official interprets a federal statute. Do not consider "statutory construction" where an administrative agency or official acts "pursuant to" a statute, unless the Court interprets the statute to determine if administrative action is proper. Consider "interpretation of administrative regulation or rule, or executive order" if the majority treats federal administrative action in arriving at its decision.Consider "diversity jurisdiction" if the majority said in approximately so many words that under its diversity jurisdiction it is interpreting state law. Consider "federal common law" if the majority indicate that it used a judge-made "doctrine" or "rule; if the Court without more merely specifies the disposition the Court has made of the case and cites one or more of its own previously decided cases unless the citation is qualified by the word "see."; if the case concerns admiralty or maritime law, or some other aspect of the law of nations other than a treaty; if the case concerns the retroactive application of a constitutional provision or a previous decision of the Court; if the case concerns an exclusionary rule, the harmless error rule (though not the statute), the abstention doctrine, comity, res judicata, or collateral estoppel; or if the case concerns a "rule" or "doctrine" that is not specified as related to or connected with a constitutional or statutory provision. Consider "Supreme Court supervision of lower federal or state courts or original jurisdiction" otherwise (i.e., the residual code); for issues pertaining to non-statutorily based Judicial Power topics; for cases arising under the Court's original jurisdiction; in cases in which the Court denied or dismissed the petition for review or where the decision of a lower court is affirmed by a tie vote; or in workers' compensation litigation involving statutory interpretation and, in addition, a discussion of jury determination and/or the sufficiency of the evidence.

Opinion:
FLIPPO v. WEST VIRGINIA
No. 98-8770.
Decided October 18, 1999
Per Curiam.
Petitioner’s motion to suppress evidence seized in a warrantless search of a “homicide crime scene” was denied on the ground that the police were entitled to make a thorough search of any crime scene and the objects found there. Because the rule applied directly conflicts with Mincey v. Arizona, 437 U. S. 385 (1978), we reverse.
One night in 1996, petitioner and his wife were vacationing at a cabin in a state park. After petitioner called 911 to report that they had been attacked, the police arrived to find petitioner waiting outside the cabin, with injuries to his head and legs. After questioning him, an officer entered the building and found the body of petitioner’s wife, with fatal head wounds. The officers closed off the area, took petitioner to the hospital, and searched the exterior and environs of the cabin for footprints or signs of forced entry. When a police photographer arrived at about 5:30 a.m., the officers reentered the building and proceeded to “process the crime scene.” Brief in Opposition 5. For over 16 hours, they took photographs, collected evidence, and searched through the contents of the cabin. According to the trial court, “[a]t the crime scene, the investigating officers found on a table in Cabin 13, among other things, a briefcase, which they, in the ordinary course of investigating a homicide, opened, wherein they found and seized various photographs and negatives.” Indictment No. 96-F-119 (Cir. Ct. Fayette County, W. Va., May 28, 1997), App. A to Pet. for Cert., p. 2.
Petitioner was indicted for the murder of his wife and moved to suppress the photographs and negatives discovered in an envelope in the closed briefcase during the search. He argued that the police had obtained no warrant, and that no exception to the warrant requirement justified the search and seizure.
In briefs to the trial court, petitioner contended that Mincey v. Arizona, supra, rejects a “crime scene exception” to the warrant requirement of the Fourth Amendment. The State also cited Mincey; it argued that the police may-conduct an immediate investigation of a crime scene to preserve evidence from intentional or accidental destruction, id., at 394, and characterized the police activity in this case as “crime scene search and inventory,” Brief in Opposition 12. The State also relied on the “plain view” exception, Mincey, supra, at 393 (citing Michigan v. Tyler, 436 U.S. 499, 509-510 (1978)), noting only, however, that the briefcase was unlocked.
In denying the motion, the trial court said nothing about inventory or plain view, but instead approved the search as one of a “homicide crime scene”:
“The Court also concludes that investigating officers, having secured, for investigative purposes, the homicide crime scene, were clearly within the law to conduet a thorough investigation and examination of anything and everything found within the crime scene area. The examination of [the] briefcase found on the table near the body of a homicide victim in this case is clearly something an investigating officer could lawfully examine.” App. A to Pet. for Cert., at 3.
After hearing an oral presentation of petitioner’s petition for appeal of this ruling, and with the full record before it, the Supreme Court of Appeals of West Virginia denied discretionary review. No. 982196 (Jan. 13, 1999), App. B to Pet. for Cert.
A warrantless search by the police is invalid unless it falls within one of the narrow and well-delineated exceptions to the warrant requirement, Katz v. United States, 389 U. S. 347, 357 (1967), none of which the trial court invoked here. It simply found that after the homicide crime scene was secured for investigation, a search of “anything and everything found within the crime scene area” was “within the law.” App. A to Pet. for Cert., at 3.
This position squarely conflicts with Mincey v. Arizona, supra, where we rejected the contention that there is a “murder scene exception” to the Warrant Clause of the Fourth Amendment. We noted that police may make war-rantless entries onto premises if they reasonably believe a person is in need of immediate aid and may make prompt warrantless searches of a homicide scene for possible other victims or a killer on the premises, id., at 392, but we rejected any general “murder scene exception” as “inconsistent with the Fourth and Fourteenth Amendments— ... the warrantless search of Mincey’s apartment was not constitutionally permissible simply because a homicide had recently occurred there.” Id., at 395; see also Thompson v. Louisiana, 469 U. S. 17, 21 (1984) (per curiam). Mincey controls here.
Although the trial court made no attempt to distinguish Mincey, the State contends that the trial court’s ruling is supportable on the theory that petitioner’s direction of the police to the scene of the attack implied consent to search as they did. As in Thompson v. Louisiana, supra, at 23, however, we express no opinion on whether the search here might be justified as consensual, as “the issue of consent is ordinarily a factual issue unsuitable for our consideration in the first instance.” Nor, of course, do we take any position on the applicability of any other exception to the warrant rule, or the harmlessness vel non of any error in receiving this evidence. Any such matters, properly raised, may be resolved on remand. 469 U. S., at 21; see also United States v. Matlock, 415 U. S. 164 (1974).
The motion for leave to proceed in forma pauperis and the petition for a writ of certiorari are granted, the judgment of the Circuit Court of West Virginia, Payette County, is reversed, and the case is remanded for further proceedings not inconsistent with this opinion.
It is so ordered.
The photographs included several taken of a man who appears to be taking off his jeans. Hie was later identified as Joel Boggess, a friend of petitioner and a member of the congregation of which petitioner was the minister. At trial, the prosecution introduced the photographs as evidence of petitioner’s relationship with Mr. Boggess and argued that the victim’s displeasure with this relationship was one of the reasons that petitioner may have been motivated to kill her.
The State suggests that the trial court’s finding that the search was “within the law” could be read as premised on the theories of plain view, exigent circumstances, and inventory that the State advanced below. No trace of this reasoning appears in the trial court’s opinion, which instead appears to undermine the State’s interpretation. It seems implausible that the court found that there was a risk of intentional or accidental destruction of evidence at a “secured” crime scene or that the authorities were performing a mere inventory search when the premises had been secured for “investigative purposes” and the officers opened the briefcase “in the ordinary course of investigating a homicide.” Nor does the court’s validation of “investiga[ting] and examin[ing]... anything and everything found within the crime scene area,” including photographs inside a closed briefcase, apparently rest on the plain-view exception. App. A to Pet. for Cert., at 2, 3.
