                      NATURE OF CASE
   Thomas Kalkowski donated 159 acres of land to the
Nebraska National Trails Museum Foundation (NNTM).
At the time of the donation, NNTM leased the land back
to Kalkowski and allowed Kalkowski to farm the land.
Kalkowski’s upgrades to the land ultimately caused the num-
ber of certified irrigated acres (CIAs) assigned to the land
to almost double. Hoping to transfer the CIAs to a nearby
property, Kalkowski filed suit, claiming that he was entitled
to the CIAs and that NNTM had been unjustly enriched. After
a bench trial, the district court found in favor of NNTM and
Gregory J. Beal, a lienholder of the property. Kalkowski now
appeals that decision. We determine that Kalkowski is not
entitled to the CIAs either under the lease agreement or under
the theory of unjust enrichment.
   In addition, while this case was pending before the judge,
Kalkowski contacted the general manager of another natural
resources district and inquired about the water rights associated
with property owned by the judge hearing the case. After the
conversation with Kalkowski, the general manager contacted
the judge and the two had a discussion regarding Kalkowski.
The judge then disclosed the conversation pursuant to Neb.
Rev. Code of Judicial Conduct § 5-302.9(B).
   Kalkowski filed a motion to recuse, arguing that the judge
should have ended the conversation after Kalkowski’s name

was brought up and also that the judge’s status as an owner of
irrigated farmland which was being leased to a farmer created
a conflict of interest or at least the appearance of a conflict of
interest. The district court denied the motion to recuse, and
Kalkowski now also appeals that order. We hold that the dis-
trict court did not abuse its discretion in denying the motion
to recuse.

                        BACKGROUND
Removal of CIAs.
   In 2000, Kalkowski agreed to donate 159 acres of land
located in Keith County, Nebraska, to NNTM. Due to a prob-
lem with a tax form, the land was not actually deeded to
NNTM until 2003. A warranty deed granting NNTM the prop-
erty in fee simple absolute and a quit claim deed were both
filed with the Keith County register of deeds. This is not the
first dispute between Kalkowski and NNTM concerning this
parcel of land.1
   At the time the gift was made, Kalkowski and NNTM
entered into a lease agreement. Under the lease agreement,
Kalkowski agreed to pay the annual taxes on the property and
$500 per year in exchange for the right to farm the land. The
lease will terminate if and when NNTM constructs a museum
of at least 5,000 square feet which would be open to the public.
A museum has yet to be built on the property.
   The lease also provides that Kalkowski owns all of the
irrigation equipment on the property and is responsible for all
expenses related to the farming operations conducted on the
real estate. With regard to improvements, Kalkowski has “the
right to make any and all improvements he deems necessary.”
Kalkowski must “pay for and maintain these improvements,”
and Kalkowski has “the right to remove any and all improve-
ments.” The term “improvements” is not defined under the
lease agreement.

   This dispute is over the ownership of the CIAs associated
with the land. In 2004, the Nebraska Legislature granted natu-
ral resources districts more authority and autonomy in regulat-
ing ground water within their respective districts.2 In particular,
the legislation provided that each natural resources district
could craft its own rules on how to best regulate the use of
ground water.3
   The Twin Platte Natural Resources District (TPNRD), where
the relevant parcel of land is located, settled on a CIAs sys-
tem of water management. A TPNRD representative testified
that this system works by designating a finite number of acres
within the district which are approved for irrigation by ground
water, in conjunction with instituting a moratorium on the
creation of new wells within the district. The representative
testified that any acre of land within the district that had been
irrigated for at least 1 year between 2001 and 2005 would be
designated as a CIA by TPNRD.
   The legislation also provides that subject to district approval,
CIAs can be transferred “between parcels or tracts under the
control of a common landowner or other person.”4 The initial
certification of the CIAs by TPNRD was recorded with the
register of deeds of the county where the land was located. Any
subsequent transfers of the CIAs to another parcel must also be
recorded with the county’s register of deeds.5
   The CIAs were assigned by TPNRD to specific parcels of
land, and individual CIAs are under the control of the owner
of those specific parcels of land. Unless reserved, the CIAs
assigned to a particular parcel would run with the land in the
event of a transfer of the real estate. The district court deter-
mined that the market value of a single CIA within the area in
question is approximately $2,000 to $2,500.
   Kalkowski testified that in anticipation of the impending
certification process, he commenced irrigation activities on

the NNTM land and cleared out shrubs and trees to increase
the number of CIAs prior to the certification date. The dis-
trict court determined that as a result of Kalkowski’s actions,
the number of CIAs on the NNTM land increased from 75.9
to 152.9. A representative from TPNRD testified that had
Kalkowski done nothing between 2000 and 2005, those addi-
tional CIAs would have been lost forever and the parcel would
have been certified with only 75.9 CIAs.
   In 2010, Kalkowski purchased 78 acres of land near the
NNTM land. Although Kalkowski had received preliminary
approval from TPNRD to transfer the CIAs from the NNTM
land to the newly purchased land, the NNTM board of direc-
tors refused to complete the necessary transfer documents.
Kalkowski filed a complaint in the district court for Keith
County alleging that NNTM would be unjustly enriched if it
were allowed to maintain possession of the CIAs. Kalkowski
requested that the district court either direct NNTM to execute
the transfer documents or award Kalkowski the value of the
benefit accrued by NNTM.
   After a bench trial, the district court determined that NNTM
was not unjustly enriched by Kalkowski’s upgrades to the
land. The district court stated that Kalkowski’s “sole reason
in improving the condition of the subject real estate was to
benefit himself in raising crops through the implementation
of irrigation on the subject real estate” and that while NNTM
certainly did receive a benefit, “NNTM did nothing to encour-
age [Kalkowski] to remove trees or shrubbery, or to utilize
his own equipment, labor, or irrigation wells located on adja-
cent real estate to irrigate the subject property between 2000
and 2005.”

Recusal.
   Kalkowski also assigns that the district court judge who
heard the case erred in not recusing himself from the proceed-
ings after the judge had a telephone conversation with the man-
ager of another natural resources district regarding Kalkowski.
While this case was pending before the judge, Kalkowski
contacted the general manager of another natural resources
district and inquired about the water rights on property owned
                     Nebraska Advance Sheets
	          KALKOWSKI v. NEBRASKA NAT. TRAILS MUSEUM FOUND.	803
	                          Cite as 290 Neb. 798

by the judge. The general manager then contacted the judge
and indicated to the judge that Kalkowski represented himself
as a prospective buyer of the judge’s property within that dis-
trict. The judge notified the general manager that the judge did
not intend to sell his property. Kalkowski denies representing
himself as a prospective buyer. Pursuant to § 5-302.9(B), the
judge later notified the parties of the conversation with the
general manager.
   Kalkowski filed a motion to recuse, contending that the
judge should not have had any further conversation with the
manager after Kalkowski’s name was brought up. Kalkowski
also argued that the fact the judge was leasing irrigated farm-
land located in another natural resources district to a farmer
created a conflict of interest. Finally, Kalkowski suggested that
at the very least, the judge’s ownership of the property created
the appearance of impropriety.
   The judge denied the motion to recuse. The judge ruled that
Kalkowski presented no evidence that the two natural resources
districts had similar rules or that the judge’s tenant paid or
provided the labor for the irrigation system on the judge’s
property. Additionally, the judge noted that it was Kalkowski’s
own actions which caused the general manager to contact the
judge and that Kalkowski could not use his own conduct as an
opportunity to “‘judge-shop.’”
                 ASSIGNMENTS OF ERROR
  Kalkowski assigns, reordered and restated, that the district
court erred in (1) ruling that Kalkowski was not entitled to the
CIAs or compensation for the CIAs in lieu of transfer and (2)
overruling the motion to recuse the trial judge.

                          ANALYSIS
Removal of CIAs.
   Kalkowski assigns that the district court erred in ruling that
Kalkowski was not entitled to the additional CIAs or to com-
pensation for the CIAs. Kalkowski set forth two different argu-
ments as to why he is entitled to recovery: First, Kalkowski
argues that under the lease agreement, he is entitled to remove
the CIAs, and second, Kalkowski argues he is entitled to resti-
tution, because NNTM was unjustly enriched.
Recovery Under Lease
Agreement.
   [6,7] The lease agreement provides that Kalkowski is entitled
to remove improvements from the parcel of land. Kalkowski
argues that the CIAs should be treated as improvements under
the lease, which would legally entitle Kalkowski to remove the
CIAs. The lease agreement does not define the term “improve-
ments”; therefore, we give the term its plain and ordinary
meaning.12 “Trade terms, legal terms of art, numbers, common
words of accepted usage and terms of a similar nature should

be interpreted in accord with their specialized or accepted
usage unless such an interpretation would produce irrational
results or the contract documents are internally inconsistent.”13
Our interpretation of the term “improvements,” as a legal term
of art, should be informed by its typical usage within farm
lease agreements.
   This court has previously defined improvements, generally,
as “‘everything that enhances the value of premises perma-
nently for general uses.’”14 This includes “‘not only buildings
and fixtures, but also many other things which are not build-
ings or fixtures.’”15 An improvement has also been defined as
a “permanent addition to or betterment of real property that
enhances its capital value and that involves the expenditure of
labor and money and is designed to make the property more
useful or valuable as distinguished from ordinary repairs.”16
A CIA, in the sense that its attachment to a piece of prop-
erty increases the value of said property, may fall within this
broad definition.
   However, it appears that the term “improvement,” within
the context of a lease, has never traditionally included intan-
gible property like CIAs. The few courts to have addressed the
issue have limited the definition of improvement to tangible
property only.17 Furthermore, this court’s own list of “‘the
most common illustrations of improvements’” all involved
the addition of tangible property to the real estate.18 The plain
and ordinary definition of the term “improvement” does not
include CIAs.

   Although Kalkowski did the work that resulted in TPNRD’s
assigning the CIAs to the property, Kalkowski did not actually
transfer the CIAs to the land. Under TPNRD rules, NNTM,
as the owner of the real estate, is entitled to legal ownership
of the additional CIAs. Kalkowski is arguably entitled to the
tangible property (i.e., irrigation equipment) that he installed
which led to the creation of the additional CIAs, but the CIAs
themselves are a different matter. The CIAs are intangible
property legally owned by NNTM, and the lease agreement
does not permit Kalkowski to remove the CIAs. The argument
that Kalkowski is entitled to the CIAs under the terms of the
lease agreement is without merit.

Recovery Under Unjust
Enrichment Theory.
   [8,9] Kalkowski argues, in the alternative, that NNTM was
unjustly enriched by Kalkowski’s work on the property. There
is no doubt that NNTM was enriched by Kalkowski’s work
on the property, but we must determine whether NNTM was
enriched unjustly. “The fact that a recipient has obtained a
benefit without paying for it does not of itself establish that
the recipient has been unjustly enriched.”19 It is a “bedrock
principle of restitution” that unjust enrichment occurs when
there has been a “‘transfer of a benefit without adequate
legal ground.’”20
   [10] Unjust enrichment is a malleable concept and avail-
able in a variety of situations. However, the Restatement
(Third) of Restitution and Unjust Enrichment21 makes it clear
that restitution is not available “for an unrequested benefit
voluntarily conferred, unless the circumstances of the trans-
action justify the claimant’s intervention in the absence of
[a] contract.” For example, restitution is not available on an

assumpsit claim when the payments were voluntarily made to
the recipient.22
   [11,12] Similarly, restitution is unavailable if it would “sub-
ject an innocent recipient to a forced exchange.”23 The idea of
avoiding a “forced exchange” through restitution stems from
the concept that the parties should usually be free to enter—or
not enter—into contracts according to their own free will.24
Therefore, subject to various exceptions,25 restitution will not
be available “if the effect of payment would be to complete an
exchange that—had it been proposed as a contract—the recipi-
ent would have been free to reject.”26
   Kalkowski had no reasonable grounds to expect compensa-
tion from NNTM in the form of the CIAs or their fair market
value for the upgrades made to the property. NNTM in no way
indicated that it wished for Kalkowski to undertake the work.
Although in hindsight Kalkowski’s work appears reasonable
and a good investment, he was not actually compelled to carry
out the work in a way that made his actions involuntary. In
addition, NNTM should have been free to decide whether it
wished to enter into an agreement where NNTM compensated
Kalkowski in some way in exchange for Kalkowski’s perform-
ing work on the land which was aimed at increasing the num-
ber of CIAs assigned to the parcel. Had Kalkowski made the
offer before he undertook his work, NNTM certainly would
have been free to refuse. An award of restitution in this case
would result in a classic forced exchange. Because the benefits
were voluntarily conferred by Kalkowski and NNTM would
have been free to reject Kalkowski’s offer had it been made,
NNTM was not unjustly enriched.
   Kalkowski’s assignment of error is without merit.

Recusal.
   [13] Kalkowski assigns that the trial judge erred in failing to
recuse himself from the proceedings after the judge had a dis-
cussion with the general manager of another natural resources
district concerning Kalkowski. A trial judge should recuse
himself or herself when a litigant demonstrates that a reason-
able person who knew the circumstances of the case would
question the judge’s impartiality under an objective standard
of reasonableness, even though no actual bias or prejudice
is shown.27
   [14] A party may not rely on his or her own conduct as
a way to force a judge to recuse himself or herself from the
proceedings. For instance, in State v. Ellefson,28 a criminal
defendant, after his conviction, professed his innocence in
several letters to the judge who presided over the defendant’s
trial. We held that the judge was not required to recuse him-
self from hearing the defendant’s motion for postconviction
relief.29 To hold otherwise would mean that “all any party in
a legal proceeding would have to do in order to disqualify
a judge would be to write a series of nasty letters, and then
claim ‘foul.’”30
   In this case, the only reason the judge had any contact with
the general manager of the natural resources district was due
to Kalkowski’s own actions. Kalkowski could have avoided
the entire situation by simply refraining from contacting the
other natural resources district concerning the judge’s property.
The fact that the judge owns and leases irrigated farmland in
another natural resources district would not lead a reason-
able person to question the judge’s impartiality. There is no
evidence in the record before us to indicate that the natural
resources district where the judge’s land is located even regu-
lates its water supply in the same way TPNRD does. The dis-
trict court did not abuse its discretion in denying Kalkowski’s

                          Filed May 1, 2015.      No. S-14-367.

 1.	 Summary Judgment: Appeal and Error. An appellate court will affirm a lower
      court’s grant of summary judgment if the pleadings and admissible evidence
      offered at the hearing show that there is no genuine issue as to any material facts
      or as to the ultimate inferences that may be drawn from those facts and that the
      moving party is entitled to judgment as a matter of law.
 2.	 Courts: Dismissal and Nonsuit: Appeal and Error. The exercise of the power
      to dismiss a matter for lack of prosecution rests in the sound discretion of the trial
      court, whose ruling will not be disturbed on appeal in the absence of a showing
      of an abuse of discretion.
 3.	 Appeal and Error. Appellants are required to point out the factual and legal
      bases that support their assignments of error.
  4.	 ____. An argument that does little more than restate an assignment of error does
      not support the assignment, and an appellate court will not address it.
  5.	 ____. An appellate court will not address arguments that are too generalized or
      vague to be understood.
 6.	 Actions: Parties: Standing: Jurisdiction. Before a party is entitled to invoke a
      court’s jurisdiction, that party must have standing to sue, which involves having
      some real interest in the cause of action.
 7.	 Actions: Parties: Standing. To have standing to sue, a plaintiff must have some
      legal or equitable right, title, or interest in the subject matter of the controversy.
 8.	 ____: ____: ____. The purpose of an inquiry as to standing is to determine
      whether one has a legally protectable interest or right in the controversy that
      would benefit by the relief to be granted.
 9.	 Declaratory Judgments. Where declaratory relief is sought, an actual contro-
      versy must be present.
10.	 Standing: Claims: Parties. Standing requires that a plaintiff show his or her
      claim is premised on his or her own legal rights as opposed to rights of a
      third party.
