Vague Fourteenth Amendment References Cannot Create Federal Jurisdiction Over State-Law Claims Against Private Drug-Testing Providers

1. Introduction

Case: Bobby R. Williams v. Omega Laboratories Inc., No. 25-13436 (11th Cir. June 26, 2026) (per curiam) (not for publication).
Parties: Bobby R. Williams (pro se plaintiff-appellant) sued Omega Laboratories, Inc. (the testing laboratory) and Dr. George E. Platt (physician retained to administer the test).

Williams took a mandatory pre-/initial-employment drug test for a truck-driving job and tested positive. He disputed the accuracy of the result, was terminated, and then filed an administrative complaint with the Florida Medical Board alleging “misconduct” by Dr. Platt. After the Board dismissed his complaint, Williams filed a federal lawsuit asserting only state-law claims: medical negligence and “forgery/alteration of records” against Dr. Platt, negligence/breach of duty against Omega, and a stand-alone request styled as “equitable tolling.”

The central issues on appeal were jurisdictional and procedural:

  • Whether Williams established federal subject-matter jurisdiction (diversity or federal-question).
  • Whether a service issue regarding the magistrate judge’s report and recommendation (R&R) deprived him of a fair opportunity to object.
  • Whether the district court conducted the required de novo review of the R&R and had any basis to apply equitable tolling.

2. Summary of the Opinion

The Eleventh Circuit affirmed the dismissal without prejudice for lack of subject-matter jurisdiction. The court held:

  • Service/objections: Any initial failure to deliver the R&R was cured when the district court extended the objection deadline and resent the R&R; Williams in fact filed objections demonstrating he had read it.
  • De novo review: The district court’s express statement that it reviewed de novo the issues raised by objections was sufficient; it was not required to rewrite the magistrate judge’s analysis.
  • No diversity jurisdiction: The amended complaint failed to allege the defendants’ citizenship.
  • No federal-question jurisdiction: Merely asserting that state-law claims “implicate” Fourteenth Amendment due process interests in “fair and reliable medical testing” was inadequate—particularly where the defendants were private actors and the complaint asserted only state-law causes of action.
  • Equitable tolling: The court lacked power to reach merits issues such as tolling once it determined jurisdiction was absent.

3. Analysis

A. Precedents Cited

1) Jurisdictional pleading and the limits of “federal issue” jurisdiction

  • Merrell Dow Pharms. Inc. v. Thompson, 478 U.S. 804, 813 (1986)
    The panel relied on the foundational principle that “the mere presence of a federal issue in a state cause of action does not automatically confer federal-question jurisdiction.” Here, Williams attempted to constitutionalize his dispute by referencing the Fourteenth Amendment, but his pleaded causes of action remained state-law negligence-type claims. The court treated his federal references as insufficient to convert the case into one “arising under” federal law.
  • Taylor v. Appleton, 30 F.3d 1365, 1367 (11th Cir. 1994)
    The court cited Taylor for the rule that a complaint must affirmatively allege a defendant’s citizenship to invoke diversity jurisdiction. Williams’ original complaint alleged diversity in a conclusory fashion; the magistrate judge granted leave to amend; the amended complaint still failed to supply the necessary citizenship allegations.
  • Univ. of S. Ala. v. Am. Tobacco Co., 168 F.3d 405, 408 (11th Cir. 1999)
    Cited to confirm the standard of review: dismissals for lack of subject-matter jurisdiction are reviewed de novo on appeal—underscoring that jurisdictional defects are not discretionary or curable by equitable considerations alone.
  • Bochese v. Town of Ponce Inlet, 405 F.3d 964, 974-75 (11th Cir. 2005)
    Used for the jurisdiction-first principle: if a court lacks subject-matter jurisdiction, it is “powerless to continue.” The panel invoked this to reject Williams’ request that the federal court proceed to merits-adjacent doctrines like equitable tolling.

2) Pro se construction—helpful but not transformative

  • Campbell v. Air Jam. Ltd., 760 F.3d 1165, 1168 (11th Cir. 2014)
    The court reiterated that pro se pleadings are construed liberally. But it immediately emphasized that liberal construction cannot manufacture a federal cause of action or supply missing jurisdictional allegations.

3) Procedure surrounding magistrate judge reports and district court adoption

  • Stephens v. Tolbert, 471 F.3d 1173, 1175 (11th Cir. 2006)
    Provided the appellate standard of review for how a district court treats a magistrate judge’s R&R: abuse of discretion. Applying that standard, the panel found no error because the district court cured service problems and allowed objections.
  • United States v. King, 849 F.2d 485, 490 (11th Cir. 1988)
    Supported the proposition that a district judge may adopt a magistrate judge’s order, and that adoption “obviates” the need for separate written findings and reasoning—so long as the district court performs the required de novo review of objected-to portions.

4) Issue preservation and abandonment

  • Access Now, Inc. v. Sw. Airlines Co., 385 F.3d 1324, 1330 (11th Cir. 2004)
    Cited for the rule that arguments not raised on appeal are abandoned. The court used it to dispose of any potential challenge to the magistrate judge’s refusal to act on later, unauthorized amendment attempts (filed without leave).

5) Equitable tolling as doctrine, not claim

  • Cabello v. Fernandez-Larios, 402 F.3d 1148, 1156 (11th Cir. 2005)
    The court cited Cabello to clarify equitable tolling’s function: it delays the running of a limitations period under certain circumstances; it is not an independent cause of action. The panel further held tolling was irrelevant on appeal because jurisdiction was absent.

B. Legal Reasoning

1) Service of the R&R and opportunity to object

Williams argued he was never served with the R&R. The panel examined the record and emphasized two procedural points grounded in the Federal Rules:

  • Under Fed. R. Civ. P. 72(b)(1), the clerk must serve the R&R as provided in Rule 5(b).
  • Under Fed. R. Civ. P. 5(b)(2)(C), service by mail to the last known address is “complete upon mailing.”

Even assuming the initial mailing failed (it was returned undeliverable), the district court remedied the issue by resending the R&R and extending the deadline. Importantly, Williams did file substantive objections—demonstrating actual notice of the R&R’s contents. The Eleventh Circuit held that the district court did not abuse its discretion by proceeding after curing the service issue.

2) De novo review does not require a second written opinion

Williams claimed the district court did not conduct de novo review or consider his objections. The panel credited the district court’s express statement that it reviewed de novo the issues raised by objections. Citing United States v. King and 28 U.S.C. § 636(b)(1), the court explained that a district court may adopt the magistrate judge’s reasoning without producing duplicative findings, so long as it performs the required review.

3) Subject-matter jurisdiction: failure of both diversity and federal-question theories

a) Diversity jurisdiction was not pleaded

Under 28 U.S.C. § 1332(a)(1), diversity jurisdiction requires (among other things) complete diversity of citizenship. The amended complaint still did not allege the defendants’ citizenship as required by Taylor v. Appleton. That omission is jurisdictionally fatal: federal courts cannot assume citizenship or infer it from sparse facts.

b) Federal-question jurisdiction was not created by constitutional language

Williams attempted to pivot from diversity to federal-question jurisdiction by asserting that his state-law claims “implicate” Fourteenth Amendment due process rights related to fair and reliable medical testing affecting “liberty and property interests.”

The court rejected that reframing for two reasons that operate together:

  • Pleading reality controls: The complaint asserted only state-law causes of action. The federal Constitution was invoked only as an abstract “implication,” not as a pleaded federal claim.
  • A “federal issue” is not enough: Under Merrell Dow Pharms. Inc. v. Thompson, referencing federal standards within state-law claims does not automatically create § 1331 jurisdiction.

The opinion also highlighted that the defendants were “a doctor and a private lab, neither of whom is a state actor,” which undercuts attempts to characterize the dispute as a Fourteenth Amendment due process case. In practical terms: due process claims generally require government action, and a private employment drug test administered by private entities does not become “state action” by mere allegation.

4) No authority to apply equitable tolling absent jurisdiction

Williams faulted the district court for not considering equitable tolling. The panel responded in two steps:

  • Equitable tolling is not a stand-alone claim (Cabello v. Fernandez-Larios).
  • Once jurisdiction is lacking, the court is “powerless to continue” (Bochese v. Town of Ponce Inlet), and must dismiss (Fed. R. Civ. P. 12(h)(3)).

C. Impact

Although unpublished, the decision is a clear, practice-relevant reminder of several recurring jurisdictional pitfalls—especially in pro se litigation:

  • Jurisdiction must be pleaded with specificity: Conclusory references to “diversity” are inadequate; citizenship allegations are essential, and failing to include them invites dismissal even where underlying facts might support diversity.
  • Constitutional buzzwords do not create § 1331 jurisdiction: A plaintiff cannot convert ordinary state tort claims arising from private employment drug testing into a federal case merely by invoking “due process” and “liberty/property interests,” particularly when defendants are private actors.
  • Courts can and will dismiss early: Rule 12(h)(3) embodies a structural limit on federal judicial power; even potentially sympathetic factual narratives cannot overcome jurisdictional defects.
  • Procedural fairness is satisfied by curing service errors: If a litigant ultimately receives the R&R, obtains an extension, and files objections, appellate courts are unlikely to reverse on service grounds.

4. Complex Concepts Simplified

  • Subject-matter jurisdiction: The federal court’s authority to hear a case. If it is missing, the court must dismiss—regardless of the merits.
  • Diversity jurisdiction (28 U.S.C. § 1332): A basis for federal jurisdiction when opposing parties are citizens of different states and the amount in controversy exceeds $75,000. “Citizenship” is not the same as “residence” and must be affirmatively alleged.
  • Federal-question jurisdiction (28 U.S.C. § 1331): Exists when the plaintiff’s well-pleaded claims arise under federal law. Mentioning federal law as background or as a “standard” within state claims is usually not enough.
  • State actor requirement (Fourteenth Amendment): Due process limits government conduct. Private individuals and companies ordinarily are not bound by the Fourteenth Amendment unless their conduct can legally be treated as governmental action.
  • Report and Recommendation (R&R): A magistrate judge’s recommended ruling. Parties may object; the district judge then reviews the objected-to parts de novo.
  • De novo review: The district judge independently considers the objected-to issues. The judge may adopt the magistrate judge’s reasoning without writing a new opinion.
  • Equitable tolling: A doctrine that can extend a filing deadline under certain conditions; it is not a separate cause of action.
  • Dismissal without prejudice: The case is dismissed, but the plaintiff may refile in a proper court (and in a proper manner), subject to limitations rules and other defenses.

5. Conclusion

The Eleventh Circuit’s decision reinforces a jurisdictional bright line: state-law negligence and record-alteration allegations against private drug-testing participants do not become a federal case by loosely invoking Fourteenth Amendment “due process” interests. The opinion also underscores that diversity jurisdiction demands specific citizenship allegations, and that once a court determines subject-matter jurisdiction is absent, it must dismiss and cannot proceed to merits-related doctrines such as equitable tolling. Procedurally, the court confirmed that any initial service mishap concerning an R&R is not reversible error where the district court cures the defect and provides a meaningful opportunity to object.
