possessed, in violation of the laws of this
state, such justice of the peace . . . or judge
shall issue his warrant to any officer having
power to serve criminal processes, and cause the
premises designated in such affidavit to be
searched. . . .46
That statutory procedure was employed in 1925, when a
search warrant application was submitted to a justice of
the peace in Henry County, Indiana. The application con-
sisted of a single affidavit, which stated that "the
undersigned affiant . . . has reason to believe and does
believe that James Wallace has in his possession intoxi-
cating liquor . . . in violation of the laws of this
state."47 On that information alone, a warrant was issued,
and then served at Wallace's residence. Wallace was pros-
ecuted and convicted of violating the liquor laws of
Indiana on the basis of incriminating evidence discovered
at his home. But he appealed his case to the state
supreme court, arguing that the search of his home had
been unconstitutional.
The Supreme Court of Indiana agreed with Wallace's
argument, finding the affidavit procedures prescribed by
the state legislature to violate the state constitution.
Here is how the court explained its ruling:
If it was intended by this statute to declare
that an allegation in the affidavit, such as
therein prescribed, shall be sufficient to show
probable cause, and that an affidavit embodying
such allegation alone is proof sufficient to war-
rant the magistrate to determine the question of
probable cause, then in our opinion the
Legislature, in that respect, exceeded its power.
. . . The averment in the affidavit amounts
solely to the possibility, not the probability,
that affiant's belief will prove to be a fact,
rather than a belief, upon the execution of the
warrant, and not before. The affidavit, if
untrue, would not subject affiant to prosecution
for perjury, unless it can be proved that affi-
ant, at the time he made the affidavit, knew
that there was no intoxicating liquor at the
place described.48
As that passage suggests, the whole purpose of the oath
requirement is to help deter false or frivolous charges by
making a sworn complaint against one's neighbor a matter
of some risk.49 Filing a complaint is supposed to be an
act of some moment--for once the complaint is filed with
