UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF TEXAS FORT WORTH DIVISION

MATTHEW LOBDELL, ET AL.,

Plaintiffs,

v. No. 4:26-cv-00919-P

UNITED STATES OF AMERICA, ET AL.,

Defendants.

MEMORANDUM OPINION & ORDER Before the Court is Plaintiffs’ Motion for Preliminary Injunction (“Motion”), filed on August 1, 2026. ECF No. 10. In their Motion, Plaintiffs request a preliminary injunction, asking the Court to enjoin Defendants from enforcing Lock-In Orders pursuant to 26 C.F.R. § 31.3402(f)(2)-1(g) (the “Regulation”) against Plaintiffs and their respective employers. However, at this stage Plaintiffs fail to establish that they suffered the irreparable injury necessary to justify the extraordinary remedy of a preliminary injunction. Accordingly, for the reasons set forth herein, after reviewing the Motion, the docket, the evidence, and the applicable law, the Court will DENY Plaintiffs’ Motion. BACKGROUND Plaintiffs are two wage earners whose employers received IRS “lock- in letters” under Treas. Reg § 31.3402(f)(2)-1(g). ECF No 11-1 at 2–21. A lock-in letter directs an employer to disregard the employee’s W-4 and instead withhold at a rate specified by the IRS. Here, the lock-in letters directed Plaintiffs’ employer to withhold at the maximum “Single 0-0” rate because it determined they were overclaiming on exemptions. ECF. No 11-1 at 2–7; see also ECF No. 15 at 5–6. This resulted in additional withholding of roughly $1,100 per paycheck and $950 per paycheck for Lobdell and Gibson, respectively. ECF No. 15 at 4. The lock-in letters were issued in November of 2024. ECF No. 11 at 7–8. Plaintiffs received notice of this determination by letter. ECF No. 11-1 at 18–21. Plaintiffs claim they made formal objections by mail and phone to the lock-in letters but that their withholding status was not reconsidered. ECF No. 11 at 2–3. On July 7, 2026, they filed a complaint seeking to enjoin and set aside the Regulation on the grounds that it violates the Administrative Procedure Act, exceeds statutory authority, and runs afoul of the procedural guarantees of the Fifth Amendment’s Due Process Clause. ECF No. 1. Then, on August 1, 2026, they sought a preliminary injunction to immediately enjoin enforcement against Plaintiffs and their respective employers and requested an expedited hearing on the matter. ECF. No 10. On August 20, 2026, The Court heard arguments from the parties and accordingly this Motion is now ripe for review. LEGAL STANDARD To merit a preliminary injunction, a movant must establish: (1) a substantial likelihood of success on the merits; (2) a substantial threat of irreparable injury; (3) the threatened injury if the injunction is denied outweighs any harm that will result if the injunction is granted; and (4) the grant of an injunction will not disserve the public interest. Healthy Vision Ass’n v. Abbott, 138 F.4th 385, 402 (5th Cir. 2025) (citing Canal Auth. v. Callaway, 489 F.2d 567, 572 (5th Cir. 1974)). If a party fails to satisfy any one of the four essential elements, a district court may not grant a preliminary injunction. Miss. Power & Light Co. v. United Gas Pipeline Co., 760 F.2d 618, 621 (5th Cir. 1985). A preliminary injunction is an “extraordinary and drastic remedy” that is to be granted “only when the movant, by a clear showing, carries the burden of persuasion” as to each element. Digital Generation, Inc. v. Boring, 869 F. Supp. 2d 761, 772 (N.D. Tex. 2012) (quoting Holland Am. Ins. Co. v. Succession of Roy, 777 F.2d 992, 997 (5th Cir. 1985)). As set forth below, Plaintiffs cannot demonstrate their entitlement to a preliminary injunction. ANALYSIS For the reasons noted in the record, the Court’s analysis proceeds in three parts. First, the Court concludes that irreparable injury is not likely in the absence of an injunction. Second, the Court concludes that Plaintiffs are unlikely to succeed on the merits. Third, the Court concludes that the balance of equities and public interest do not warrant a preliminary injunction. The Court must consider each of the preliminary injunction factors, on balance, and determine if all four collectively favor the injunction. Picker Intern., Inc. v. Blanton, 756 F. Supp. 971, 979 (N.D. Tex. 1990). If the plaintiff fails to carry its burden on any one of these four factors, a preliminary injunction cannot be granted. Enterprise Int’l, Inc. v. Corporacion Estatal Petrolera Ecuatoriana, 762 F.2d 464, 472 (5th Cir. 1985). “The decision to grant an injunction is within the sound discretion of the trial court,” Kern River Gas Trans. Co. v. Coastal Corp., 899 F.2d 1458, 1462 (5th Cir. 1990), including a preliminary injunction. Siders v. City of Brandon, 123 F.4th 293, 300 (5th Cir. 2024). The Court’s determination as to each of the four elements are mixed questions of fact and law, which will be left undisturbed unless clearly erroneous. Kern River Gas Trans. Co., 899 F.2d at 1462. A. Plaintiffs Have Not Shown That Irreparable Harm Will Result To satisfy the “irreparable harm” prong of the preliminary injunction test, a movant must show an “irreparable injury is likely in the absence of an injunction.” Winter v. Nat. Res. Def. Council, Inc., 555 U.S. 7, 22 (2008); Pendergest–Holt v. Certain Underwriters at Lloyd’s of London, 600 F.3d 562, 569 (5th Cir. 2010). Generally, “a harm is irreparable where there is no adequate remedy at law[.]” Janvey v. Alguire, 647 F.3d 585, 600 (5th Cir. 2011).1 See Chacon v. Granata, 515 F.2d 922, 925 (5th Cir. 1975). Further, the threatened harm must be “more than mere speculation.” Id. at 601. It must be proven separately and convincingly,
