May the police, without a warrant, search digital information on a cell phone seized from an individual who has been arrested? This issue has been resolved in the seminal US Supreme Court case of Riley vs. California (No. 13-132 [25 June 2014]). Ruling in the negative, the US Supreme Court declares, thus:
“We cannot deny that our decision today will have an impact on the ability of law enforcement to combat crime. Cell phones have become important tools in facilitating coordination and communication among members of criminal enterprises, and can provide valuable incriminating information about dangerous criminals. Privacy comes at a cost.
Our holding, of course, is not that the information on a cell phone is immune from search; it is instead that a warrant is generally required before such a search, even when a cell phone is seized incident to arrest. Our cases have historically recognized that the warrant requirement is “an important working part of our machinery of government,” not merely “an inconvenience to be somehow ‘weighed’ against the claims of police efficiency.” Coolidge v. New Hampshire, 403 U. S. 443, 481 (1971). Recent technological advances similar to those discussed here have, in addition, made the process of obtaining a warrant itself more efficient. See McNeely, 569 U. S., at ___ (slip op., at 11–12); id., at ___ (ROBERTS, C. J., concurring in part and dissenting in part) (slip op., at 8) (describing jurisdiction where “police officers can e-mail warrant requests to judges’ iPads [and] judges have signed such warrants and e-mailed them back to officers in less than 15 minutes”).
Moreover, even though the search incident to arrest exception does not apply to cell phones, other case-specific exceptions may still justify a warrantless search of a particular phone. “One well -recognized exception applies when ‘“the exigencies of the situation” make the needs of law enforcement so compelling that [a] warrantless search is objectively reasonable under the Fourth Amendment.’” Kentucky v. King, 563 U. S., at ___ (slip op., at 6) (quoting Mincey v. Arizona, 437 U. S. 385, 394 (1978)). Such exigencies could include the need to prevent the imminent destruction of evidence in individual cases, to pursue a fleeing suspect, and to assist persons who are seriously injured or are threatened with imminent injury. 563 U. S., at ___. In Chadwick, for example, the Court held that the exception for searches incident to arrest did not justify a search of the trunk at issue, but noted that “if officers have reason to believe that luggage contains some immediately dangerous instrumentality, such as explosives, it would be foolhardy to transport it to the station house without opening the luggage.” 433 U. S., at 15, n. 9.
In light of the availability of the exigent circumstances exception, there is no reason to believe that law enforcement officers will not be able to address some of the more extreme hypotheticals that have been suggested: a suspect texting an accomplice who, it is feared, is preparing to detonate a bomb, or a child abductor who may have information about the child’s location on his cell phone. The defendants here recognize—indeed, they stress—that such fact -specific threats may justify a warrantless search of cell phone data. See Reply Brief in No. 13–132, at 8–9; Brief for Respondent in No. 13–212, at 30, 41. The critical point is that, unlike the search incident to arrest exception, the exigent circumstances exception requires a court to examine whether an emergency justified a warrantless search in each particular case. See McNeely, supra, at ___
Our cases have recognized that the Fourth Amendment was the founding generation’s response to the reviled “general warrants” and “writs of assistance” of the colonial era, which allowed British officers to rummage through homes in an unrestrained search for evidence of criminal activity. Opposition to such searches was in fact one of the driving forces behind the Revolution itself. In 1761, the patriot James Otis delivered a speech in Boston denouncing the use of writs of assistance. A young John Adams was there, and he would later write that “[e]very man of a crowded audience appeared to me to go away, as I did, ready to take arms against writs of assistance.” 10 Works of John Adams 247–248 (C. Adams ed. 1856). According to Adams, Otis’s speech was “the first scene of the first act of opposition to the arbitrary claims of Great Britain. Then and there the child Independence was born.” Id., at 248 (quoted in Boyd v. United States, 116 U. S. 616, 625 (1886).
Modern cell phones are not just another technological convenience. With all they contain and all they may reveal, they hold for many Americans “the privacies of life,” Boyd, supra, at 630. The fact that technology now allows an individual to carry such information in his hand does not make the information any less worthy of the protection for which the Founders fought. Our answer to the question of what police must do before searching a cell phone seized incident to an arrest is accordingly simple— get a warrant.
We reverse the judgment of the California Court of Appeal in No. 13–132 and remand the case for further proceedings not inconsistent with this opinion. We affirm the judgment of the First Circuit in No. 13–212.
It is so ordered.” (Emphasis supplied)
It is modestly opined that the United States of America case law, particularly on the right to privacy and against unreasonable searches and seizures, pervades Philippine jurisprudence. In fact, former Chief Justice Reynato Puno discussed the subject matter in his separate opinion in the landmark case of Republic of the Philippines v. Sandiganbayan, et. al. (GR No. 104768 ).
Quoting US jurisprudence, Chief Justice Puno stated that the “exclusionary rule” had been incorporated in the state system the US because other means of controlling illegal police behavior had failed. He quoted at length significant US rulings, asserting that they had a significant influence in the exclusionary rule in Philippine jurisdiction:
“. . . Today we once again examine the Wolf’s constitutional documentation of the right of privacy free from unreasonable state intrusion, and after its dozen years on our books, are led by it to close the only courtroom door remaining open to evidence secured by official lawlessness in flagrant abuse of that basic right, reserved to all persons as a specific guarantee against that very same unlawful conduct. . .
… Therefore, in extending the substantive protections of due process to all constitutionally unreasonable searches - state or federal - it was logically and constitutionally necessary that the exclusion doctrine - an essential part of the right to privacy - be also insisted upon as an essential ingredient of the right newly recognized by the Wolf case. In short, the admission of the new constitutional right by Wolf could not consistently tolerate denial of its most important constitutional privilege, namely, the exclusion of the evidence which an accused had been forced to give by reason of the unlawful seizure. To hold otherwise is to grant the right but in reality to withhold its privilege and enjoyment. Only last year the Court itself recognized that the purpose of the exclusionary rule ‘is to deter - to compel respect for the constitutional guaranty in the only available way - by removing the incentive to disregard it.’ (Elkins v. United States, 364 US at 217)
