630, 6 S.Ct. 524. Having equated compulsory process
with actual searches and seizures and having melded the
Fourth Amendment with the Fifth, the Court then found
the order at issue unconstitutional because it compelled
the production of property to which the Government did
not have superior title. See id., at 622–630, 6 S.Ct. 524.
In a concurrence joined by Chief Justice Waite, Justice
Miller agreed that the order violated the Fifth
Amendment, id., at 639, 6 S.Ct. 524, but he strongly
protested the majority’s invocation of the Fourth
Amendment. He explained: “[T]here is no reason why
this court should assume that the action of the court
below, in requiring a party to produce certain papers ...,
authorizes an unreasonable search or seizure of the house,
papers, or effects of that party. There is in fact no search
and no seizure.” Ibid. “If the mere service of a notice to
produce a paper ... is a search,” Justice Miller concluded,
“then a change has taken place in the meaning of words,
which has not come within my reading, and which I think
was unknown at the time the Constitution was made.” Id.,
at 641, 6 S.Ct. 524.
Although Boyd was replete with stirring rhetoric, its
reasoning was confused from start to finish in a way that
ultimately made the decision unworkable. See 3 W.
LaFave, J. Israel, N. King, & O. Kerr, Criminal Procedure
§ 8.7(a) (4th ed. 2015). Over the next 50 years, the Court
would gradually roll back Boyd ‘s erroneous conflation of
compulsory process with actual searches and seizures.
That effort took its first significant stride in Hale v.
Henkel, 201 U.S. 43, 26 S.Ct. 370, 50 L.Ed. 652 (1906),
where the Court found it “quite clear” and “conclusive”
that “the search and seizure clause of the Fourth
Amendment was not intended to interfere with the power
of courts to compel, through a subpoena duces tecum, the
production, upon a trial in court, of documentary
evidence.” Id., at 73, 26 S.Ct. 370. Without that writ, the
Court recognized, “it would be ‘utterly impossible to
carry on the administration of justice.’ ” Ibid.
Hale, however, did not entirely liberate subpoenas duces
tecum from Fourth *2254 Amendment constraints. While
refusing to treat such subpoenas as the equivalent of
actual searches, Hale concluded that they must not be
unreasonable. And it held that the subpoena duces tecum
at issue was “far too sweeping in its terms to be regarded
as reasonable.” Id., at 76, 26 S.Ct. 370. The Hale Court
thus left two critical questions unanswered: Under the
Fourth Amendment, what makes the compulsory
production of documents “reasonable,” and how does that
standard differ from the one that governs actual searches
and seizures?
The Court answered both of those questions definitively
in Oklahoma Press Publishing Co. v. Walling, 327 U.S.
186, 66 S.Ct. 494, 90 L.Ed. 614 (1946), where we held
that the Fourth Amendment regulates the compelled
production of documents, but less stringently than it does
full-blown searches and seizures. Oklahoma Press began
by admitting that the Court’s opinions on the subject had
“perhaps too often ... been generative of heat rather than
light,” “mov[ing] with variant direction” and sometimes
having “highly contrasting” “emphasis and tone.” Id., at
202, 66 S.Ct. 494. “The primary source of misconception
concerning the Fourth Amendment’s function” in this
context, the Court explained, “lies perhaps in the
identification of cases involving so-called ‘figurative’ or
‘constructive’ search with cases of actual search and
seizure.” Ibid. But the Court held that “the basic
distinction” between the compulsory production of
documents on the one hand, and actual searches and
seizures on the other, meant that two different standards
had to be applied. Id., at 204, 66 S.Ct. 494.
Having reversed Boyd ‘s conflation of the compelled
production of documents with actual searches and
seizures, the Court then set forth the relevant Fourth
Amendment standard for the former. When it comes to
“the production of corporate or other business records,”
the Court held that the Fourth Amendment “at the most
guards against abuse only by way of too much
indefiniteness or breadth in the things required to be
‘particularly described,’ if also the inquiry is one the
demanding agency is authorized by law to make and the
materials specified are relevant.” Oklahoma Press, supra,
at 208, 66 S.Ct. 494. Notably, the Court held that a
showing of probable cause was not necessary so long as
“the investigation is authorized by Congress, is for a
purpose Congress can order, and the documents sought
are relevant to the inquiry.” Id., at 209, 66 S.Ct. 494.
Since Oklahoma Press, we have consistently hewed to
that standard. See, e.g., Lone Steer, Inc., 464 U.S., at
414–415, 104 S.Ct. 769; United States v. Miller, 425 U.S.
