Opinion

UNITED STATES DISTRICT COURT NORTHERN DISTRICT OF INDIANA SOUTH BEND DIVISION

DOMETIC CORPORATION,

Plaintiff, v. CAUSE NO. 3:24cv537 DRL-AZ

GULF STREAM COACH, INC.,

Defendant.

OPINION AND ORDER When a business relationship soured, Dometic Corporation sued Gulf Stream Coach, Inc. for breach of contract and other theories of recovery, including unjust enrichment. After the pleadings closed, Gulf Stream moved for partial judgment on the pleadings on the contract and unjust enrichment claims under Rule 12(c). The court denies the motion. BACKGROUND The amended complaint offers these facts, taking its well-pleaded allegations as true and drawing inferences in the light most favorable to Dometic, as the court must for today’s motion. Federated Mut. Ins. v. Coyle Mech. Supply Inc., 983 F.3d 307, 313 (7th Cir. 2020). Dometic manufactures products for the recreational vehicle industry [24 ¶ 6]. Gulf Stream manufactures recreational vehicles [id. ¶ 7]. From 2018 to 2023, Gulf Stream purchased thousands of such goods from Dometic [id. ¶ 8; 24-6]. During this period, the parties generally transacted in a consistent manner [24 ¶ 20]. Gulf Stream submitted a purchase order to Dometic, specifying the desired products, quantity, and price [id.; 24-3]. Dometic responded by sending Gulf Stream a sales order confirmation [24 ¶ 20]. The confirmation identified the purchase order and listed the expected shipping date, the unit price for the goods, additional surcharges, and the total cost for the deal [id.; 24-4]. Once the goods were shipped, Dometic sent Gulf Stream an invoice that mirrored information in the confirmation, except that it specifically itemized the cost of delivery [24 ¶ 20; 24-5].

The parties debate the terms of these transactions, particularly price. Dometic’s confirmations contained this clause: All sales of items shown hereon are made conditional upon buyer’s assent to the Dometic prices set forth hereon, and are subject to (1) the terms as reflected hereon, and (2) Dometic’s “terms of sale (B2B)” . . . . Any different or additional prices or terms set forth by buyer on buyer’s purchase order, published on buyer’s website or contained on any writing by buyer (before or after the date of this confirmation) are objected to and rejected. . . . If these Dometic prices or terms are not acceptable, buyer must reject and refuse (or immediately return at buyer’s cost) all shipments of the items reflected on this confirmation from Dometic, or buyer’s assent hereto shall be presumed and established for all purposes.

[24-4 (capitalization altered)]. Dometic’s invoices echoed this same proviso [24 ¶ 12; 24-5]. As relevant today, Dometic’s terms and conditions for business-to-business transactions specified that the “[b]uyer shall purchase the Goods from [Dometic] at the price[s] [] set forth in [Dometic]’s published price list in force as of [Dometic]’s shipping date” [24-1 ¶ 8(a)]. Dometic notified its customers by email of any price increases a month before they took effect and again one week before [24 ¶ 17]. As alleged, Gulf Stream never objected to these emails or confirmations from Dometic [id. ¶ 19, 21]. Gulf Stream sent checks to Dometic’s bank lockbox [id. ¶ 23]. Gulf Stream included “remittance advice” on the checks to identify the invoices they paid and included other notes and markings [id. ¶ 23, 25; 11-8]. When a check arrived, the bank notified Dometic of the payment amount and the pertinent invoice [24 ¶ 25]. Dometic did not receive the actual check or any of the information from the remittance advice [id. ¶ 24]. In 2021, midstream in the business relationship, Dometic offered a rebate program to its customers through which they could receive discounts on their purchases [id. ¶ 13]. To qualify for the program’s benefits, customers were required to provide forecasts to Dometic and sign its

“Seller’s OEM Terms and Conditions for 2021” [id.; 24-2]. Paragraph 9 of the OEM Agreement, titled “other terms and conditions of sale,” stated that “[a]ll sales of Dometic Goods shall be made pursuant to Dometic’s Standard Terms and Conditions of Sale” and explicitly incorporated those terms and conditions [24-2; 24 ¶ 15]. Gulf Stream signed the OEM Agreement on February 23, 2021 [24 ¶ 14; 24-2 at 1]. Over the course of their dealings, it was normal for Gulf Stream to have an outstanding

balance with Dometic because of the high volume of orders and the various discounts, credits, and rebates [24 ¶ 26-27]. At some point in 2022, Dometic noticed that Gulf Stream’s balance was steadily increasing [id. ¶ 33]. After reviewing Gulf Stream’s payments from 2018 to 2023, Dometic identified more than 2,000 invoices that the company alleges Gulf Stream failed to pay in full, leaving an unpaid balance of more than $3 million [id. ¶ 9, 34; 24-6]. When Dometic raised this issue with Gulf Stream, Gulf Stream explained that the

differences in payments related to delivery charges [24 ¶ 36]. By Dometic’s calculations, this only accounted for 598 short-paid invoices, not the rest [id. ¶ 37-38; 24-6]. Dometic’s investigation revealed additional ways Gulf Stream allegedly short-paid the invoices, including by basing its payments on lower prices of goods, paying 90 percent of an invoice, applying a chargeback, only paying a portion of the invoice, or not paying any portion of the invoice [24 ¶ 48-52]. Invoking diversity jurisdiction, Dometic sued Gulf Stream for breach of contract and

other claims. Gulf Stream answered the complaint, filed a counterclaim for a declaratory judgment, and moved for partial judgment on the pleadings. Dometic then filed an amended complaint, mooting Gulf Stream’s original motion. Dometic’s amended complaint asserted five counts: breach of contract (count 1); breach of Uniform Commercial Code (UCC) (count 2); with

alternative claims of unjust enrichment (count 3), account stated (count 4), and prejudgment interest (count 5). Gulf Stream renewed a motion for partial judgment based on this amended pleading and targeted counts 1-3. STANDARD After the pleadings are closed, a party may move for judgment on the pleadings. Fed. R. Civ. P. 12(c). Judgment on the pleadings is appropriate when there are no disputed issues of material fact, and the moving party is entitled to judgment as a matter of law. Unite Here Loc. 1 v.

Hyatt Corp., 862 F.3d 588, 595 (7th Cir. 2017). Save for exceptions not pertinent here, the court is confined to matters addressed in the pleadings and must review allegations in the light most favorable to the nonmoving party. See id. The pleadings include “the complaint, the answer, and any written instruments attached as exhibits.” N. Ind. Gun & Outdoor Shows, Inc. v. City of S. Bend, 163 F.3d 449, 452 (7th Cir. 1998) (citing Fed. R. Civ. P. 10(c)).
