Before MELLOY, BOWMAN, and SMITH, Circuit Judges.
                         ___________

MELLOY, Circuit Judge.

      The United States appeals from several of the district court’s adverse holdings
following a bench trial on claims against the Government under the Federal Tort
Claims Act (“FTCA”). Specifically, the Government appeals the district court’s
holding on conversion, its award of prejudgment interest, and its determination of
non-economic damages based on intentional infliction of emotional distress. We
reverse with respect to liability and damages on the conversion claim and the award
of prejudgment interest; we affirm the emotional-distress damages award.

                                           I.

       This case has been before us once before, and its earlier history can be found
in more detail in our prior opinion, Wilkinson v. United States, 

(8th Cir.
2006). Briefly, the facts are as follows. Ernest and Mollie Wilkinson1 owned several
descendable possessory interests on allotted Indian land held in trust by the Bureau
of Indian Affairs (“BIA”). During the 1970s and 1980s, the Wilkinsons mortgaged
their allotments to what is now known as the Farm Service Administration (“FSA”).
The Wilkinsons defaulted, and in 1990 the FSA wrote down their debt to the fair
market value of the land. The Wilkinsons defaulted again and stopped making
payments in 1992.

       Mollie died in 1991, Ernest suffered a heart attack and a stroke in 1993, and one
of their sons died in 1994. As a result, the Wilkinsons were generally unable to
continue farming their land. In 1996, the FSA sent a letter to the BIA asking for aid
in collecting on the Wilkinsons’ debt. In response, the BIA advertised for lease bids
for the Wilkinsons’ land in February 1997. The Wilkinsons, however, asked the BIA
not to lease the land because they intended to resume farming it that year. The BIA
refused and leased out 315 of the Wilkinsons’ 750 acres on five-year terms. With
nearly half of their land leased against their will, the Wilkinsons abandoned their




      1
        Ernest and Mollie Wilkinson had six children that joined in their farming
operations, as well as other children who did not. The named plaintiffs in this case are
the surviving four of those six. For convenience, we refer to the family generally,
rather than by the individual relevant for any particular point of the proceedings.

                                          -2-
remaining land and their farm equipment.2 At no point did the BIA take possession
of the farm equipment or of the particular land upon which it was located.

       The Wilkinsons had appealed the decision to lease their lands to the BIA’s
Superintendent for the Reservation, but their appeal had been denied. The Wilkinsons
appealed further, and in July 1998 the Interior Board of Indian Appeals (“IBIA”)
concluded that the BIA lacked authority to lease the allotments. The BIA and the
local superintendent ignored this ruling, however, and took no action to effectuate the
IBIA’s decision. In 2002, the BIA leased out the allotments again, this time for two-
year terms.

       The Wilkinsons sued, claiming trespass, conversion, intentional infliction of
emotional distress, and wrongful death of Ernest, who had died in 1998. The district
court granted summary judgment for the United States, holding that the Wilkinsons
did not have standing to sue. We reversed and outlined two issues for remand:
“whether the initial actions of BIA personnel, taken without legal authority, comprised
a federal tort or constitutional violation, and whether those actions remained devoid
of authority for the entire term of the BIA’s seizure.” 

n.6.

      After a bench trial on remand, the district court held that the BIA was without
authority and that it trespassed from 1997 to 2003.3 Although there was some
evidence that the BIA leased the land again after 2003, the district court found that the
land was not leased and that it sat idle in 2004, 2005, and 2006. The district court

      2
       The singular exception appears to be one of the remaining allotments, for
which the Wilkinsons negotiated a lease with a third party.
      3
       Pursuant to 25 C.F.R. § 162.601(a)(3), the BIA does have authority to lease an
allotment on behalf of the “undetermined heirs of a decedent’s estate.” Several
members of the Wilkinson family died during the relevant period, and the Government
argued that some of the leases were proper under this authority. The district court
held otherwise, and the Government does not raise this issue on appeal.

                                          -3-
held, however, that the BIA’s trespass continued through 2006, because even though
the land may not have been leased after 2003, there was no evidence that the BIA
informed the Wilkinsons of this fact, and thus it was the BIA’s fault the land remained
idle. The district court also determined that lands the BIA never leased were not
trespassed on. The district court further held that the BIA had converted the farm
equipment through its trespass on the leased farm lands and the consequent
“paralyzing” of the Wilkinsons’ farming operations.

       The district court also held that the BIA intentionally inflicted emotional
distress on the Wilkinsons through its “extreme and outrageous disregard for our
government’s conflict resolution system” and by its continued defiance of the IBIA
and of the Wilkinsons’ rights, even while seeing the “great emotional angst” the BIA’s
actions caused the Wilkinsons. Finally, however, the district court found that the BIA
was not responsible for the death of Ernest Wilkinson.

       The district court assessed damages on the successful claims and adjusted the
trespass and conversion damages to “present value” by using a 5% rate of return,
resulting in a sum of $232,407.4 The district court then reduced the total amount by
$4,838 that the BIA had already paid to the Wilkinsons, resulting in a sum of
$227,569 in economic damages. In determining non-economic damages for the
intentional infliction of emotional distress claim, the district court awarded an
additional “$232,407 for their emotional distress, an amount equal to the economic
damages the Wilkinsons have endured.”




      4
       There is some discrepancy regarding whether the district court intended
$72,000 or $78,000 to be the base figure for conversion damages. Because we reverse
with respect to the conversion claim and the damages thereon, we need not consider
which figure is appropriate.

                                         -4-
                                           II.

       We note at the outset that the Government does not appeal the district court’s
finding that the BIA trespassed on the Wilkinsons’ property. Nor does it appeal the
district court’s holding that the court should assess non-economic damages for
intentional infliction of emotional distress. The district court’s finding as to the fair
rental value for the trespass is not at issue, but the Government has appealed the
adjustment of that amount to present value, contending that it is a prohibited award
of prejudgment interest. In addition, the Government appeals the finding of
conversion of the Wilkinsons’ personal property as well as the amount of non-
economic emotional-distress damages the court awarded.

A. Conversion

       The district court concluded that the BIA’s leasing of the Wilkinsons’
allotments “had a paralyzing effect on their farming operation” and was therefore a
conversion of the Wilkinsons’ farming equipment. Under North Dakota law, “the trial
court’s determination about whether a conversion has been committed is a finding of
fact.” Paxton v. Wiebe, 

, 79 (N.D. 1998). We review the district
court’s factual findings for clear error. Fed. R. Civ. P. 52(a)(6); Chapa v. United
States, 

, 889 (8th Cir. 2007).

       “Conversion consists of a tortious detention of personal property from the
owner, or its destruction, or a wrongful exercise of dominion or control over the
property inconsistent with or in defiance of the rights of the owner.” 

(quotation omitted); see also Restatement (Second) of Torts § 222A(1)
(1965) (“Conversion is an intentional exercise of dominion or control over a chattel
which so seriously interferes with the right of another to control it that the actor may
justly be required to pay the other the full value of the chattel.”). North Dakota courts
have long recognized that conversion does not require that the defendant assert
dominion over the property for his own benefit; rather, the defendant need only

                                          -5-
interfere with the owner’s interests to a sufficient degree. See, e.g., Christensen v.
Farmers State Bank of Richardton, 

, 357 (N.D. 1968) (“The gist of
conversion is not in acquiring the complainant’s property, but in wrongfully depriving
him of it . . . and it is of little [relevance] that the converter received no benefit from
such deprivation.”). “[I]t is the degree of such interference which makes a
conversion,” William L. Prosser, The Nature of Conversion, 42 Cornell L.Q. 168, 172
(1956–57), and there is no conversion without “interfere[nce] with an owner’s use to
an actionable degree.” Harwood State Bank v. Charon, 

, 603 (N.D.
1991) (emphasis added). To reach an actionable degree, the interference must be “of
such a degree as to require a forced sale of the plaintiff’s interest in the goods to the
defendant.” Dairy Dep’t v. Harvey Cheese, Inc., 

, 144 (N.D. 1979).

      As the underlying facts are not contested, the question before us is whether the
BIA’s leasing of the Wilkinsons’ allotments, alone, was sufficient to constitute an
“actionable degree” of interference rising to the level of a “forced sale” of the farm
equipment to the BIA. The Restatement (Second) of Torts informs us that:

      In determining the seriousness of the interference and the justice of
      requiring the actor to pay the full value, the following factors are
      important: (a) the extent and duration of the actor’s exercise of dominion
      or control; (b) the actor’s intent to assert a right in fact inconsistent with
      the other’s right of control; (c) the actor’s good faith; (d) the extent and
      duration of the resulting interference with the other’s right of control; (e)
      the harm done to the chattel; (f) the inconvenience and expense caused
      to the other.

Restatement (Second) of Torts § 222A(2). Here, the BIA exercised no control over
the farm equipment; the BIA did not assert any right over the farm equipment; the
BIA did no harm to the farm equipment; and the BIA did not detain or directly
interfere with the farm equipment, either physically or through the legal process. The
inconvenience and expense caused were limited to the Wilkinsons’ inability to use the
equipment on the leased farm land. Even accepting the district court’s conclusion that

                                           -6-
leasing half of the land “paralyzed” all of the farming operations, such indirect and
incomplete interference cannot support a claim of conversion.

       The Wilkinsons cite no case where a court found conversion based solely on an
indirect interference with a specific use of property and without interference with
physical possession of that property. See generally W. Page Keeton et al., Prosser and
Keeton on the Law of Torts § 15 (5th ed. 1984) (hereinafter Prosser and Keeton).
While there may be instances where interference with an owner’s right to use his
property may completely “deprive[] [the owner] of the possibility of any enjoyment
thereof or benefit therefrom” even without interference with possession, Leach v.
Kelsch, 

, 364 (N.D. 1960) (quotation omitted), conversion is
primarily “an offense against possession of property” that “consists of an act in
derogation of the plaintiff's possessory rights.” 

(quotations omitted)
(emphasis added); see Dairy 

(“Conversion is a tort having
its origin in the old common law of trover” and “is generally committed by an
unauthorized transfer or disposal of possession of goods to one who is not entitled to
them.”). Thus, few interferences will amount to conversion if they do not interfere
with the possessory interest, and it remains the case that “where there is no denial of
plaintiff’s property, and no claim of property in the defendant, there can be no
conversion.” Nye v. Johnson, 

, 821 (N.D. 1942); cf. 

–80 (“Even where the tenant alleges that he was wrongfully evicted, the
landlord is not liable in conversion for taking from the premises personalty belonging
to the tenant, where the landlord in no way exercises dominion over the personal
property in derogation of the tenant’s rights.” (quotation omitted)).

       At common law, there is a separate claim for “trespass to chattel” that is
generally regarded as differing from conversion only in degree, and where
interference is not complete, trespass to chattel may be a more appropriate claim. See
Pearson v. Dodd, 

, 706 (D.C. Cir. 1969) (“Where the intermeddling falls
short of the complete or very substantial deprivation of possessory rights in the

                                         -7-
property, the tort committed is not conversion, but the lesser wrong of trespass to
chattels.”); Restatement (Second) of Torts § 222A cmt. a (explaining that “the present
rule . . . regards conversion as an exercise of the defendant’s dominion or control of
the chattel, as distinguished from a mere interference with the chattel itself, or with
possession of it”). Compare N.D. Cent. Code § 32-03-23 (regarding damages for
conversion) with 

(regarding damages for injury to property).

        Because a conversion must be the equivalent of a forced sale to the defendant,
the tort of conversion is more severe than the tort of trespass to chattel, which
generally is something less than a forced sale justifying payment of full value of the
chattel. See Restatement (Second) of Torts § 222A cmt. c (“Usually, although not
necessarily, [trespass to chattel] damages are less than the full value of the chattel
itself. In conversion the measure of damages is the full value of the chattel, at the time
and place of the tort.”). The “forced sale” nature of conversion emphasizes the
essential distinction between conversion and trespass to chattel; namely, in a
conversion, the interference is so severe as to justify the serious remedy of payment
of the full value of the chattel. See Buri v. Ramsey, 

, 625 (N.D. 2005)
(describing the statutory “presumption that the detriment caused by the conversion
equals the value of the property” (quotation omitted)). It follows, then, that a claim
of conversion cannot stand where the interference is too incomplete to totally deprive
the plaintiff of the chattle. Prosser, The Nature of 

(“Conversion has been confined, in effect, to those major interferences which are so
important, or serious, as to justify the forced judicial sale of the chattel to the
defendant which is the distinguishing feature of the action.”).5


      5
        As to a claim for the lesser-interference tort of trespass to chattel, a theory not
argued here, we note that where there has been no dispossession of the property,
“liability for trespass to chattels exists only on a showing of actual damage to the
property interfered with.” 

(citing F. Harper & F. James, The
Law of Torts § 2.3 (1956)); Prosser and Keeton, § 14 at 87 (“[I]n the absence of any
actual damage the action will not lie.”). The Wilkinsons were not dispossessed of

                                           -8-
       Our conclusion that no conversion occurred is further supported by the fact that
the district court did not appear to consider ownership of the equipment to pass to the
BIA (as it would if converted for full value), because, under North Dakota law, a
plaintiff may be awarded either the value of the property or the return of the property.
See N.D. Cent. Code § 32-03-23; 

(“If the owner elects a
return of the converted property, the present value of that property must be considered
in mitigation of damages . . . .”). Allowing the Wilkinsons to both retain the farm
equipment and receive the full value of the farm equipment would be contrary to the
notion of a “forced sale” and inconsistent with North Dakota law.

       We cannot justifiably expand the scope of North Dakota’s law of conversion
to treat the interference here as being so complete so as to be a forced sale requiring
additional damages equal to the full value of the farm equipment. See Ashley County
v. Pfizer, Inc., 

, 673 (8th Cir. 2009) (“It is not the role of a federal court
to expand state law in ways not foreshadowed by state precedent, and our review of
related [state] case law does not foreshadow such an expansion.” (alteration and
citations omitted)). In considering the district court’s holding that the BIA’s trespass
had the secondary effect of converting the farm equipment, we are “left with a definite
and firm conviction a mistake has been made.” 

(standard
of review).

B. Prejudgment Interest

       The Government also contests the district court’s increase of damages to reflect
“present value,” because the United States cannot be held liable for prejudgment
interest on claims under the FTCA. 28 U.S.C. § 2674. The Wilkinsons do not deny
that the present-value adjustment is an award of prejudgment interest; rather, they



their farm equipment, and the BIA caused no damage to the farm equipment;
therefore, no trespass to chattel claim could stand.

                                           -9-
contend that such interest is allowed as “just compensation” under the Fifth
Amendment. See U.S. Const. amend V. Despite the Wilkinsons’ claims, the district
court did not “make clear that this case involved taking of private property by the
Government.” To the contrary, the Wilkinsons do not argue a Fifth Amendment
claim, and there is no indication that the district court considered a constitutional
violation. The damages were clearly based on North Dakota tort law under the FTCA,
and accordingly no prejudgment interest may be awarded. Cf. Washington v. Drug
Enforcement Admin., 

, 873 (8th Cir. 1999) (“[C]onstitutional wrongs
cannot be remedied through the FTCA.”).

C. Non-Economic Damages

       Finally, the Government argues that the district court determined the non-
economic damages simply by doubling the economic damages, with no independent
basis for its calculation, and therefore the non-economic damages must be revised
downward to reflect all reductions from the initial $232,407 economic-damages
calculation. We review a district court’s calculation of non-economic damages under
the FTCA for abuse of discretion, and “we must defer to the district court’s
assessment of damages unless there is plain injustice or a monstrous or shocking
result.” St. John v. United States, 

, 678 (8th Cir. 2001) (internal
quotations omitted). Damages are determined according to the relevant state law,
except that punitive damages are not allowed under the FTCA. 28 U.S.C. § 2674; St.

.

       The Government’s argument rests primarily on the underlying assertion that
“non-economic damages were calculated solely as a function of economic damages”
with “no independent basis in the record.” We disagree with this fundamental premise
of the Government’s argument. The district court’s comment that the non-economic
damages were “an amount equal to the economic damages the Wilkinsons have
endured” was not a holding that emotional damages were to be determined by the

                                        -10-
economic damages. The emotional distress damages were not based on the economic
loss of the trespass and alleged conversion. See Dahlen v. Landis, 

,
68 (N.D. 1981) (“[T]he determination of damages for pain and suffering and
comparable losses is not susceptible of an arithmetical calculation.”). Rather, the
district court based the damages on the “stress, frustration, and anger the Wilkinsons
must have felt towards the BIA, an agency that is supposed to act as their fiduciary”
but instead “openly ignored what may have been in the best interests of the family”
and “demonstrate[d] a completely willful and arrogant defiance of our country’s
administrative and judicial process.” The district court properly based the non-
economic damage award on the ongoing anguish the BIA caused the Wilkinsons,
anguish amplified by the BIA’s position of power over the family. See Swenson v.
N. Crop Ins., Inc., 

, 185 (N.D. 1993) (“The position of the parties is
relevant when examining the facts for instances of extreme and outrageous conduct.”);
see also Zuger v. State, 

, 622 (N.D. 2004) (“[T]he degree of
outrageousness of a defendant’s conduct may itself be important evidence of severe
emotional distress necessary to support a claim for intentional infliction of emotional
distress.” (quotation omitted)). Our reversal of the district court’s conversion holding
in no way changes the “stress, frustration, and anger” the BIA caused.

      Similarly, the Government’s argument that the emotional-distress damages must
be reduced by the amount of rent the BIA paid to the Wilkinsons must also fail.
Although it may be that receiving some small portion of the amount owed reduced the
emotional distress by a like amount, such a reduction is not, as the Government
argues, “mandated by law and logic.”

      Given the prolonged and obstinate abuse of power by the Wilkinsons’ fiduciary,
the BIA, we cannot say that the district court abused its discretion or assessed a
“shocking” level of non-economic damages, even after a portion of the related
economic damages are removed from consideration.



                                         -11-
                                    * *       *

       For the foregoing reasons, we reverse the district court with respect to the
conversion claim, damages thereon, and the calculation of prejudgment interest, and
we affirm the emotional-distress damages award. Accordingly, the economic-
damages award is reduced from $227,569 to $85,904, resulting in the total damages
award being reduced from $459,976 to $318,311. We remand the case to the district
court for entry of an amended judgment consistent with this opinion.
