Henson v. SCDC: No Interlocutory Appeal of Class-Certification Orders; “Predominance” and a Qualitative Commonality Test Are Inherent in Rule 23(a)

Court: Supreme Court of South Carolina
Date: July 22, 2026
Disposition: Reversed and remanded

I. Introduction

Calvin Henson, Daniel James Collins, Jason Robinson, Russell Taylor and All Those Similarly Situated (collectively, “Henson”) sued the South Carolina Department of Corrections (SCDC) and the South Carolina Department of Juvenile Justice (SCDJJ) alleging negligence in prison management—principally, failures to implement/enforce protective policies and to provide sufficient staffing—resulting in sexual assaults.

The circuit court certified two sweeping classes: all individuals in SCDC custody and all individuals in SCDJJ custody “from 2012 until present” who were “victims of a nonconsensual sexual battery.” The court of appeals dismissed the agencies’ attempt to appeal the certification order as interlocutory. The Supreme Court of South Carolina then issued a common-law writ of certiorari directly to the circuit court and took up two foundational questions:

  • Appellate procedure: whether class certification orders can ever be immediately appealed to the court of appeals; and
  • Class action standards: how South Carolina’s Rule 23(a) should handle the balance between classwide issues and individualized issues (including whether “predominance” is effectively required).

II. Summary of the Opinion

Justice Few, writing for a unanimous Court, held:

  • Immediate appealability: “an interlocutory order granting or denying class certification is never immediately appealable to the court of appeals. There are no exceptions.”
  • Certiorari remains extraordinary: the Court reiterated it will entertain a petition for a common-law writ of certiorari to review an interlocutory class-certification order only in “rare and exceptional circumstances.”
  • Rule 23(a) requires qualitative commonality and inherent predominance: South Carolina’s Rule 23(a) demands a qualitative showing that common issues are “determinative” and “overshadow” individualized issues—embracing as “inherent” what federal practice labels “predominance.”
  • Overruling: “To this extent only, we overrule Littlefield v. S.C. Forestry Comm'n,” rejecting the notion that omission of federal Rule 23(b)/(c) made South Carolina class actions more expansive.
  • Application: these rape/sexual-assault negligence claims would require overwhelming individualized mini-trials on (1) class membership, (2) proximate cause, and (3) damages (and possibly negligence standards over time), defeating Rule 23(a)’s efficiency rationale. Certification was reversed and the case remanded for discovery and trial only on the named plaintiffs’ individual claims.

III. Analysis

A. Precedents Cited (and How They Shaped the Result)

1. Interlocutory review and certiorari

  • Hensley v. S.C. Dep't of Soc. Servs. — Previously used flexible language (“ordinarily not immediately appealable”) and avoided merits because the class order was interlocutory. Henson resolves the ambiguity by announcing a categorical rule: class certification orders are never immediately appealable to the court of appeals.
  • Salmonsen v. CGD, Inc., Ferguson v. Charleston Lincoln Mercury, Inc., and Eldridge v. City of Greenwood — Earlier cases contained “general rule”/“usually”/“only in certain circumstances” phrasing. Henson recharacterizes the field: those formulations no longer imply any exception for immediate appeal of certification orders.
  • Hughes ex rel. Estate of Hughes v. Bank of Am. Nat'l Ass'n — Mentioned to clarify that part of Ferguson had been “overruled in part on other grounds,” underscoring the Court’s careful housekeeping of class-action doctrine.
  • Roberts v. Recovery Bureau, Inc. and Hite v. Thomas & Howard Co. of Florence — Preserved as a distinct, discretionary doctrine: if an appealable issue is already before the appellate court, the court may consider an otherwise unappealable ruling to avoid unnecessary litigation. Henson expressly states this principle survives and is not an “exception” to the non-appealability of certification orders.
  • State v. Price and Laffitte v. Bridgestone Corporation — Define the narrow lane for common-law certiorari: correcting errors of law where the trial court exceeded authority, and only in “exceptional circumstances,” not as a substitute for appeal. These cases justify the Court’s unusual decision to reach the merits here while warning litigants not to treat certiorari as routine class-certification review.

2. Rule 23(a): commonality, rigorous analysis, and “predominance” (in substance)

  • Gardner v. South Carolina Department of Revenue — The Court’s anchor for a qualitative commonality requirement. Although some issues were common, certification failed because individualized “prejudice” proof meant no “determinative critical issue” overshadowed others. Henson extends that logic to prison sexual-assault negligence: individualized class-membership, causation, and damages questions swamp any alleged common negligence issue.
  • Stott v. Haworth — Quoted in Gardner for the “determinative critical issue” formulation. Henson reaffirms this as the operative meaning of commonality in South Carolina.
  • McGann v. Mungo — Early appellate interpretation of Rule 23(a) emphasizing efficiency: issues must be “sufficiently similar so that the class action will be a more efficient means” of resolution. Henson revives this efficiency-centered view as the rule’s animating principle.
  • Waller v. Seabrook Island Prop. Owners Ass'n — Reinforces the need for “rigorous analysis” at certification. Henson models that approach by walking through how a class trial would actually unfold (mini-trials, juries, notice/opt-out, then liability, then causation/damages).
  • Littlefield v. S.C. Forestry Comm'n — Had stated omission of federal Rule 23(b) requirements made South Carolina more expansive. Henson rejects that implication and overrules Littlefield to that extent, aligning South Carolina’s functional approach with stricter, efficiency-protecting limits.

3. Persuasive federal authority and due-process guardrails

  • Wal-Mart Stores, Inc. v. Dukes — Central to Henson’s reframing of “commonality” as a qualitative inquiry: class procedure must generate “common answers apt to drive the resolution of the litigation.” The Court uses Dukes to explain why “common questions” in abundance are insufficient if factual dissimilarities block common answers.
  • Tyson Foods, Inc. v. Bouaphakeo and Amchem Prods., Inc. v. Windsor — Provide modern descriptions of “predominance” as cohesion and the relative importance of common vs. individual issues. Henson adopts these concepts in substance while insisting they are already inherent in South Carolina’s Rule 23(a).
  • Phillips Petroleum Co. v. Shutts — Cited for due process: absent class members must be adequately represented. Henson connects this to practical trial burdens and to counsel’s fiduciary duties when the putative class could be enormous.
  • Premium Inv. Corp. v. Green — South Carolina authority recognizing fiduciary obligations to absent class members; used to underscore why counsel cannot simply “pare down” to a manageable subset without implicating duties to the whole.

4. Negligence elements and individualized proof

  • Hurd v. Williamsburg Cnty. — Proximate cause is essential in negligence.
  • J.T. Baggerly v. CSX Transp., Inc. and Bramlette v. Charter-Med.-Columbia — Proximate cause includes “causation-in-fact,” proved by “but for” causation. Henson uses these to show why each assault would require individualized causation proof: even “perfect compliance” with standards cannot prevent all misconduct, so a classwide causation finding is implausible.

5. “Fail-safe” class concerns (acknowledged, but resolved through Rule 23(a))

  • EQT Prod. Co. v. Adair and Messner v. Northshore Univ. HealthSystem — Cited to define “fail-safe” classes: membership depends on having a valid claim. The Court did not formally adopt an independent “ascertainability” doctrine or decide fail-safe doctrine as a standalone ground; instead it treated these concerns as symptoms of the deeper Rule 23(a) defect—individualized trials to determine who is even in the class.

6. Rule interpretation method

  • Swing v. Swing and Whitfield v. Schimpf — Reflect the Court’s recent insistence on anchoring procedural decisions in the Rules’ text. Henson harmonizes text with purpose: while focusing on Rule 23(a)’s words, the Court insists efficiency is “inescapable” in class certification analysis.

B. Legal Reasoning

1. A categorical appellate rule for class certification orders

The Court announces a bright-line rule: interlocutory orders granting or denying class certification are never immediately appealable to the court of appeals. This eliminates prior ambiguity created by “ordinarily”/“usually” language in earlier decisions and forces class-certification disputes into one of two channels: (1) review after final judgment, or (2) in truly extraordinary cases, a discretionary common-law certiorari petition to the Supreme Court.

The Court simultaneously preserves the narrow Roberts v. Recovery Bureau, Inc./Hite v. Thomas & Howard Co. of Florence pathway: an appellate court may, in its discretion, address an unappealable ruling if doing so is necessary to resolve an appealable issue already before it and avoid unnecessary litigation. But that doctrine does not convert certification orders into appealable orders; it is merely an efficiency tool when jurisdiction otherwise exists.

2. Certiorari: available, but intentionally difficult

Applying State v. Price and Laffitte v. Bridgestone Corporation, the Court stresses that common-law certiorari is not an “appeal by another name.” It will be used only rarely to correct errors of law—especially where a trial court exceeded authority—and litigants should not “lightly” seek it. The Court treats this case as exceptionally suitable for intervention because the certification order, if left unreviewed, would impose massive, court-overwhelming trial mechanics inconsistent with Rule 23’s design.

3. Rule 23(a) in South Carolina: qualitative commonality plus inherent predominance

The Court reframes South Carolina class certification around a single practical demand: class procedure must actually deliver efficiency. That requires more than identifying any shared question. Drawing from Gardner v. South Carolina Department of Revenue, McGann v. Mungo, and Wal-Mart Stores, Inc. v. Dukes, the Court holds that common questions must be:

  • Significant and genuinely capable of producing classwide “common answers,”
  • Determinative of the claims’ validity “in one stroke,” and
  • So central that they overshadow the individualized questions the court would otherwise have to try.

This is, in substance, a “predominance” requirement. The Court expressly “embrace[s] the ‘inherent’ requirement of predominance” described by Lightsey & Flanagan, while insisting it is not new law but a clarification of what Rule 23(a) has always demanded when properly applied.

4. Why this particular class action fails Rule 23(a)

The Court’s “rigorous analysis” focuses on how the case would be tried:

  • Class membership itself requires mini-trials: because the class is limited to those who were actually victims of nonconsensual sexual battery, a jury would have to decide, inmate-by-inmate, whether each person was “raped” before that person can be included in the class. With at least 1,768 reports (and potentially far more), this is unmanageable as a threshold matter.
  • Negligence may not yield a single common answer: the alleged standard of care and compliance are not static “from 2012 until present.” The Court uses PREA’s evolving federal standards, reporting regimes, and audit/certification variations—plus differences across facility types—to show that negligence could vary materially by time, place, and prison category. That variability undercuts the premise that one classwide negligence finding can “drive the resolution” for everyone.
  • Proximate cause is inherently individualized: under Hurd, J.T. Baggerly, and Bramlette, plaintiffs must prove “but for” causation. The Court views it as “obvious” that even perfect prison management cannot prevent all sexual misconduct, making inmate-specific causation proof unavoidable.
  • Damages are individualized: each assault claim requires personal evidence and individualized valuation.
  • Due process and fiduciary duties exacerbate manageability problems: because counsel owes fiduciary duties to absent class members (citing Phillips Petroleum Co. v. Shutts and Premium Inv. Corp. v. Green), counsel cannot simply litigate a small, convenient subset and ignore weaker claims without implicating obligations to the whole putative class.

On these premises, any “common question” is overwhelmed. The class device would multiply, not reduce, adjudicative labor—precisely the opposite of Rule 23(a)’s purpose.

C. Impact

1. Appellate practice: a bright-line jurisdictional shift

  • No immediate appeals: parties can no longer attempt to appeal class certification orders to the court of appeals under any “limited circumstances” theory.
  • Certiorari petitions will be scrutinized: the Court invites petitions only in “rare and exceptional circumstances,” signaling that most certification disputes must await final judgment.
  • Strategic consequences: defendants facing class certification must focus on building a record at the circuit court and, if necessary, pursue later review; plaintiffs must anticipate that certification will be evaluated under a strict efficiency-centered framework.

2. Substantive class-action doctrine: South Carolina aligns functionally with “predominance”

  • Predominance is now explicit in substance: while Rule 23(a) remains unchanged textually, trial courts must apply an “inherent” predominance requirement—common issues must be determinative and must overshadow individualized issues.
  • Littlefield’s “more expansive” statement is no longer reliable: by overruling Littlefield v. S.C. Forestry Comm'n “to this extent only,” the Court rejects arguments that South Carolina’s omission of federal Rule 23(b)/(c) expands class availability.
  • Manageability and fail-safe concerns are folded into Rule 23(a): even without adopting a standalone “ascertainability” test, the Court’s approach effectively demands objective, workable class definitions because unworkable membership determinations will defeat commonality/predominance.

3. Tort claims with individualized elements face higher certification headwinds

Claims requiring individualized proof of injury occurrence, causation-in-fact, and damages—particularly where membership turns on proving a contested event—will be difficult to certify. Henson is especially significant for institutional negligence suits (schools, hospitals, detention facilities) alleging systemic failures but involving individualized incidents.

IV. Complex Concepts Simplified

  • Interlocutory order: a non-final ruling made while the case is ongoing. Ordinarily, appellate courts review only final judgments; Henson holds class certification orders are not immediately appealable, period.
  • Common-law writ of certiorari: an extraordinary, discretionary tool allowing the Supreme Court to correct certain legal errors when ordinary appeal routes are inadequate—used only in exceptional circumstances.
  • Rule 23(a) “commonality”: not merely that everyone shares some question, but that class treatment can produce a single answer that meaningfully advances everyone’s claims in a way that justifies aggregation.
  • “Predominance” (as used here): common issues must be more important than individual issues; if a case will devolve into many individual trials, class treatment is improper even if some legal questions are shared.
  • Fail-safe class: a class defined so that membership depends on winning (e.g., “all people who were unlawfully harmed”); it forces the court to decide merits just to know who is in the class and can unfairly shield class members from losing.
  • Proximate cause / “but for” causation: the plaintiff must show the harm would not have happened without the defendant’s negligence; Henson treats this as inevitably individualized for assault incidents.
  • Opt-out class and notice: South Carolina uses an “opt-out” procedure (discussed via Salmonsen v. CGD, Inc.), requiring notice to absent members and a chance to be excluded—adding practical burdens when class membership cannot be determined without trials.

V. Conclusion

Henson is a major procedural decision with two durable holdings. First, class certification orders—grants or denials—are never immediately appealable to the court of appeals, eliminating prior uncertainty and channeling challenges into post-judgment review or rare Supreme Court certiorari. Second, the Court crystallizes South Carolina’s Rule 23(a) into a strict, efficiency-driven standard: common issues must be qualitatively determinative and must predominate in substance by overshadowing individualized issues. Applying that framework, the Court found that individualized trials over class membership, causation, and damages would swamp any shared negligence issue in prison sexual-assault claims, making class treatment incompatible with Rule 23(a)’s purpose.
