                                             Order

   In 2005 Don Leis acquired agricultural property in Randolph County, Indiana. The
farm grew corn and beans. By 2007 Leis and entities he controlled had converted the
property to a pig farm with 2,800 hogs. Neighbors who objected to the stench filed this
nuisance suit under the diversity jurisdiction. 28 U.S.C. §1332. The district court granted
summary judgment for the defendants, ruling that the Indiana Right to Farm Act, Ind.
Code §32-30-6-9, blocks their claim. 2012 U.S. Dist. LEXIS 130773 (S.D. Ind. Sept. 13,
2012).

   Here is the text of §32-30-6-9:

     (a) This section does not apply if a nuisance results from the negligent opera-
     tion of an agricultural or industrial operation or its appurtenances.
No. 12-3339                                                                          Page 2

     (b) The general assembly declares that it is the policy of the state to conserve,
     protect, and encourage the development and improvement of its agricultural
     land for the production of food and other agricultural products. The general
     assembly finds that when nonagricultural land uses extend into agricultural
     areas, agricultural operations often become the subject of nuisance suits. As a
     result, agricultural operations are sometimes forced to cease operations, and
     many persons may be discouraged from making investments in farm im-
     provements. It is the purpose of this section to reduce the loss to the state of
     its agricultural resources by limiting the circumstances under which agricul-
     tural operations may be deemed to be a nuisance.
     (c) For purposes of this section, the continuity of an agricultural or industrial
     operation shall be considered to have been interrupted when the operation
     has been discontinued for more than one (1) year.
     (d) An agricultural or industrial operation or any of its appurtenances is not
     and does not become a nuisance, private or public, by any changed condi-
     tions in the vicinity of the locality after the agricultural or industrial opera-
     tion, as the case may be, has been in operation continuously on the locality for
     more than one (1) year if the following conditions exist:
       (1) There is no significant change in the type of operation. A significant
       change in the type of agricultural operation does not include the following:
          (A) The conversion from one type of agricultural operation to another
          type of agricultural operation.
          (B) A change in the ownership or size of the agricultural operation.
          (C) The:
              (i) enrollment; or
              (ii) reduction or cessation of participation;
          of the agricultural operation in a government program.
          (D) Adoption of new technology by the agricultural operation.
       (2) The operation would not have been a nuisance at the time the agricul-
       tural or industrial operation began on that locality.

Plaintiffs’ main argument in the district court was that the conversion of the land from
crops to a “concentrated animal feeding operation” (which is what Indiana’s regulatory
officials call the defendants’ business) was a “significant change” for the purpose of
paragraph (d)(1). The district court rejected this because subparagraph (d)(1)(A) says
that a change from one type of agricultural operation to another is not “significant”.

   Plaintiffs do not renew that argument on appeal. Instead they contend that the rec-
ord does not show “any changed conditions in the vicinity of the locality after the agri-
cultural … operation … has been in operation continuously” for a year, as subsection
No. 12-3339                                                                            Page 3

(d) requires. Citing Wendt v. Kerkhof, 594 N.E.2d 795, 798 (Ind. App. 1992), and TDM
Farms, Inc. v. Wilhoite Family Farm LLC, 969 N.E.2d 97 (Ind. App. 2012), plaintiffs main-
tain that the Act’s function is to change the common-law rule that a person “coming to
the nuisance” could sue to abate it. See also Toftoy v. Rosenwinkel, 2012 IL 113569 (Nov.
29, 2012) (same reading of the comparable statute in Illinois). They did not come to the
pig farm, they observe; the pig farm came to them.

    The problem with this argument—beside the fact that it was not made in the district
court and has been forfeited—is that the land appears to have been in agricultural use
since 1956, long before plaintiffs bought their parcels, if not earlier. The exact date is not
in the record, nor does the record show whether the agricultural use has been interrupt-
ed for a year or more. That shortcoming may be attributable to plaintiffs’ decision not to
present this argument in the district court, but no matter. Plaintiffs make nothing of
these details. Instead they say that “the agricultural … operation” for the purpose of
subsection (d) means the pig farm, not the prior use of the land. That argument won’t
fly. Subsection (d) says “the agricultural operation”, not “the current agricultural opera-
tion” or anything similar. Subparagraph (d)(1)(B) illustrates the difference by providing
that a change in ownership or size is not “significant.” If, as plaintiffs assert, a change in
ownership restarts the clock for the purpose of subsection (d), then subparagraph
(d)(1)(B) would be useless. So would subparagraph (d)(1)(A), which says that a change
in the type of agricultural operation is not significant. We read these subparagraphs to
show that subsection (d) as a whole starts the one-year clock from the time any agricul-
tural use began on a parcel of land. Only a “significant” change starts a new clock.

   Plaintiffs do not contend that a pig farm would have been a nuisance in the 1950s,
before non-farmers moved to the vicinity. Thus paragraph (d)(2) does not help them.
They pin their remaining hopes on subsection (a), which provides that the entire Act
“does not apply if a nuisance results from the negligent operation of an agricultural …
operation”. They insist that defendants have operated their pig farm negligently.

   The district judge wrote that “ample evidence” (when viewed favorably to plaintiffs)
shows that the defendants operated several aspects of the pig farm negligently. His
opinion (at *16) gives ten examples. But the judge added that the record would not
permit a reasonable trier of fact to conclude that these shortcomings cause the stench
that aggrieves plaintiffs. Id. at *16–21. The judge concluded that every farm with 2,800
hogs, no matter how well operated, emits odors that plaintiffs would find obnoxious.

    Plaintiffs contend that the district judge erred because the Act lacks a causation re-
quirement. We don’t understand this. Here’s subsection (a) again, with emphasis: the
Act “does not apply if a nuisance results from the negligent operation of an agricultural …
operation”. Unless the nuisance “results from” the negligence, and not just from the ag-
ricultural operation, the Act applies and defeats plaintiffs’ claim. See Lindsey v. DeGroot,
898 N.E.2d 1251 (Ind. App. 2009). What’s more, causation is an ingredient of every fed-
No. 12-3339                                                                              Page 4

eral suit; otherwise there’s no standing. See, e.g., Steel Co. v. Citizens for Better Environ-
ment, 523 U.S. 83, 102–03 (1998).

    According to plaintiffs, several of the defendants’ shortcomings in operating the pig
farm contribute to odors. That suffices to show causation, plaintiffs insist—enough, at
least, to create a material dispute whose resolution belongs to a jury. But if the odor
from a well-operated pig farm would make plaintiffs’ land unlivable (as they insist it
has become), a small increment is irrelevant. Plaintiffs’ experts did not make any at-
tempt to quantify the extent of the odor-enhancing effects of the defendants’ shortcom-
ings. Indeed, they did not offer even a rough qualitative estimate, such as the difference
between “a lot” and “a little.” Plaintiffs have not attempted to identify any large, well-
run pig farm that avoids emitting the sort of noxious odors that plaintiffs say makes this
farm a nuisance. Without any effort to show that a well-run pig farm is not a nuisance,
or even any effort to show that the shortcomings plaintiffs see in defendants’ operations
contribute materially to how surrounding landowners perceive the farm’s odors, there
is nothing for a jury to determine.

   Plaintiffs may believe that at a trial they could present the sort of information that
the district judge found missing from this record. But summary judgment is the time
when litigants must assemble the admissible evidence. Like the district court, we must
evaluate the record as it stands. On this record, a reasonable jury could not find that the
shortcomings plaintiffs’ experts found in defendants’ operations make the difference
between a nuisance and a good neighbor. The judgment therefore is affirmed.
