Embedded Objects as “Defects in the Sidewalk”: Michigan Supreme Court Clarifies MCL 691.1402a in Mann v. City of Detroit
Case: Kenneth Mann v. City of Detroit
Court: Michigan Supreme Court
Date: June 11, 2025
Docket: SC 166619 (COA 361637; Wayne CC 21-003705-NO)
Introduction
In a precedential order issued in lieu of granting leave, the Michigan Supreme Court held that a metal stub embedded in and protruding from a paved public sidewalk is a “sidewalk defect” under MCL 691.1402a. The ruling clarifies that, for purposes of the Governmental Tort Liability Act’s (GTLA) sidewalk exception, a hazard can be both:
- a “vertical discontinuity defect of 2 inches or more in the sidewalk” (MCL 691.1402a(3)(a)), and
- a “dangerous condition in the sidewalk itself” (MCL 691.1402a(3)(b)).
The plaintiff, Kenneth Mann, tripped over a five-inch-tall, four-inch-wide metal stub paved into the middle of a sidewalk. The City of Detroit sought summary disposition under MCR 2.116(C)(7), arguing governmental immunity. The Court of Appeals agreed with the City, reasoning that the protruding signpost remnant was not part of the sidewalk. The Supreme Court reversed, concluding the object fell squarely within MCL 691.1402a(3). The case is remanded for further proceedings.
Summary of the Opinion
The Court reversed Part II(B)(2) of the Court of Appeals’ judgment and remanded, holding that Detroit was not entitled to summary disposition under MCR 2.116(C)(7) because the metal stub was a sidewalk defect under MCL 691.1402a. Specifically:
- The five-inch protrusion constituted a “vertical discontinuity defect of 2 inches or more in the sidewalk” under MCL 691.1402a(3)(a).
- Because the stub was embedded in the concrete and located in the pedestrian pathway, it also constituted a “dangerous condition in the sidewalk itself” under MCL 691.1402a(3)(b).
- The statutory phrase “paved public sidewalk” in MCL 691.1401(f) does not restrict liability to defects in pavement material alone; it identifies the sidewalks to which the duty applies (paved public, not unpaved or private).
- The Court criticized the Court of Appeals for relying on factually distinguishable cases rather than the text of MCL 691.1402a(3).
- The holding is consistent with the Legislature’s intent to impose a duty to maintain sidewalks in reasonable repair (2012 amendments) and to permit municipalities to assert premises defenses including open and obvious (2016 amendments).
Justice Welch concurred, emphasizing that the object is plainly a “defect in the sidewalk” of the sort the Legislature intended to address. Justice Zahra dissented, arguing the signpost remnant was not part of the sidewalk and warning that the majority’s approach risks expanding municipal liability beyond the statute’s narrow exception to immunity. Justice Hood did not participate.
Analysis
Precedents Cited and Their Roles
-
Ray v. Swager, 501 Mich 52 (2017). Cited for the standard of review: the Court reviews de novo both summary disposition decisions and the application of governmental immunity. This underscores that the legal question—whether the sidewalk exception applies—is for the Court to decide anew.
-
Sunrise Resort Ass’n, Inc. v. Cheboygan Co. Rd. Comm’n, 511 Mich 325 (2023). Clarifies that, on an MCR 2.116(C)(7) motion, the complaint’s allegations are accepted as true unless contradicted by the movant’s documentation. This procedural backdrop supports denying immunity-based dismissal where the record shows a qualifying sidewalk defect.
-
Ross v. Consumers Power Co. (On Rehearing), 420 Mich 567 (1984). Reinforces that governmental immunity is broad and exceptions are narrowly construed. The majority’s analysis adheres to this principle by rooting its holding in the precise text of MCL 691.1402a(3) and the object’s embedded location within the walking surface.
-
Robinson v. City of Lansing, 486 Mich 1 (2010). Discusses the historical “two-inch rule” and the prior linkage between sidewalks and the highway exception. The Court uses this history to explain the post-2012 shift: the Legislature moved sidewalk claims into a dedicated provision (MCL 691.1402a) with an affirmative duty on municipalities.
-
Rouch World, LLC v. Dep’t of Civil Rights, 510 Mich 398 (2022). Cited for the interpretive directive to ascertain and effectuate legislative intent through statutory text. The majority faults the Court of Appeals for relying on factually distinct cases instead of the controlling statutory language “in the sidewalk” and the defined rebuttal pathways in MCL 691.1402a(3).
-
LaMeau v. City of Royal Oak, 490 Mich 949 (2011) (reversing COA). The earlier case involved a guy wire attached to an anchor cemented near the sidewalk; the plaintiff was injured by the wire suspended above the walkway. The majority distinguishes LaMeau because the embedded anchor did not directly interact with the pedestrian, whereas here the embedded metal stub in the walking path caused the fall. The dissent views LaMeau as supportive of excluding fixtures from “the sidewalk.”
-
Weaver v. Detroit, 252 Mich App 239 (2002), and Ali v. Detroit, 218 Mich App 581 (1996). Both Court of Appeals cases construe the highway exception and treat fixtures (a streetlight pole; a bus shelter) as outside the “highway” despite attachment to or proximity with sidewalks. The dissent cites these as persuasive; the majority finds them factually distinguishable and, in any event, less probative given the Legislature’s later, specific treatment in MCL 691.1402a.
-
Plunkett v. Dep’t of Transp., 286 Mich App 168 (2009). Quoted by the dissent to emphasize broad governmental immunity, framing the sidewalk exception as a narrow carve-out.
Legal Reasoning
The Court anchors its reasoning in the text of MCL 691.1402a, as amended in 2012 and 2016. Three aspects of the statutory framework are central:
-
Affirmative Duty and Presumption of Reasonable Repair (Subsections (1) and (3)).
Municipalities must “maintain the sidewalk in reasonable repair,” but enjoy a presumption that they have done so. A plaintiff may rebut that presumption only by showing that a proximate cause of the injury was:
- a vertical discontinuity of at least two inches in the sidewalk, or
- a dangerous condition in the sidewalk itself of a particular character other than solely a vertical discontinuity.
The Court held that the five-inch protruding stub simultaneously satisfies both routes: it is a vertical discontinuity greater than two inches and a dangerous condition in the sidewalk itself, because it is embedded into and protrudes from the walkway where pedestrians step.
-
Meaning of “in the sidewalk” and “paved public sidewalk.”
The City argued that “paved public sidewalk” in MCL 691.1401(f) limits liability to flaws in the pavement material. The Court rejected that reading. The definitional phrase delineates the sidewalks to which the duty applies (paved, public, pedestrian), not the types of hazards covered. The operative text in subsection (3)—“in the sidewalk” and “in the sidewalk itself”—does not confine coverage to cracks or holes in concrete; it encompasses hazards physically embedded in and part of the walking surface that disrupt pedestrian travel.
-
Simultaneous Applicability of Subsections (3)(a) and (3)(b).
The statute expressly permits rebuttal of the presumption by “1 or both” conditions. The dissent objected that the majority’s reasoning blends the two paths without identifying a non-discontinuity danger. The majority answered that the embedded metal stub is both a discontinuity (height change) and a distinctive dangerous condition located in the sidewalk itself, and the statute authorizes overlap.
The majority also addressed a practical concern raised by the dissent: would this logic expose municipalities to liability if a pedestrian walked into a typical sign mounted high above the walkway? The Court said no. “Vertical discontinuity” connotes an irregularity or lack of continuity in the walking surface; a standard sign seven feet in the air is not such a discontinuity. By contrast, a five-inch metal stub embedded in the sidewalk is an abnormal, irregular obstruction in the pedestrian pathway.
Finally, the Court clarified that the Court of Appeals erred by relying on factually different “fixture” cases that either predate the 2012 restructuring of sidewalk liability or involve hazards not in the walking surface itself (e.g., suspended wires or adjacent poles).
Impact and Practical Implications
The decision significantly clarifies the reach of MCL 691.1402a and will influence both municipal risk management and litigation strategy in sidewalk-injury cases.
Key Impacts
- Embedded hazards are actionable. Objects physically embedded in the paved surface and protruding into the walking path—such as cut-off signposts, pipe stubs, valve or utility boxes that protrude, or similar embedded obstructions—may qualify as defects “in the sidewalk” under MCL 691.1402a(3).
- Not every object near a sidewalk is a “sidewalk defect.” The Court’s reasoning distinguishes normal, elevated fixtures (e.g., a standard-height signpost) and adjacent fixtures from hazards embedded in the walking surface. The focus is on hazards in the pedestrian pathway, not above or alongside it.
- Both statutory rebuttal routes may apply. Plaintiffs can invoke subsection (3)(a) and (3)(b) together when the condition is both a ≥2-inch vertical discontinuity and a distinct danger in the sidewalk itself.
-
Municipal defenses remain. On remand, the City may still raise:
- Notice under MCL 691.1402a(2): plaintiff must show the city knew or should have known of the defect at least 30 days before the injury;
- the open and obvious defense and other premises-liability defenses under MCL 691.1402a(5); and
- causation and comparative fault issues.
- Municipal risk management. Cities should audit sidewalks for embedded protrusions and adopt removal or mitigation protocols (e.g., flush-cutting or capping signpost remnants, leveling utility boxes) because such hazards now more clearly fall within MCL 691.1402a.
Effects on Future Cases
- Litigants will pivot from debating whether fixtures are “part of the sidewalk” to whether an object is embedded “in the sidewalk itself” and within the pedestrian pathway.
- Trial courts will more frequently resolve the presumption-rebuttal question as a matter of law (MCL 691.1402a(4)) when measurement and location (e.g., a five-inch stub in the walking surface) are undisputed.
- Cases involving hazards above the walkway or adjacent to it (wires, elevated signs, poles alongside the slab) will remain less likely to qualify under MCL 691.1402a(3) absent an embedded or integrated condition in the walking surface.
Understanding the Dissent
Justice Zahra would have affirmed the Court of Appeals. The dissent’s core points:
- Not “part of the sidewalk.” The protruding signpost remnant stood on top of the sidewalk, and therefore, in the dissent’s view, was distinct from the sidewalk itself. If it is not part of the sidewalk, the analysis should end: the sidewalk exception does not apply.
- Fixture cases and statutory exclusions. The dissent relies on pre-2012 highway-exception cases (Weaver, Ali) and LaMeau to argue that fixtures attached to or near sidewalks are not “sidewalks.” The dissent also points to the definitional exclusion of “utility poles” from the “highway” definition (MCL 691.1401(c)) as a signal that poles and similar fixtures are outside the exception.
- Scope-creep concern. The dissent warns the majority’s approach could eliminate immunity whenever a pedestrian collides with an embedded or attached object, including ordinary signposts, and criticizes the majority for not identifying a danger other than “vertical discontinuity” to satisfy subsection (3)(b).
The majority answers that “vertical discontinuity” concerns the walking surface; normal, elevated signage is plainly not a discontinuity, whereas a five-inch embedded stub is an abnormal interruption in the path. The majority also stresses the text of the post-2012 sidewalk statute over fixture cases arising under the older, more generalized highway exception.
Complex Concepts Simplified
- Governmental immunity (GTLA): Michigan law broadly shields governmental entities from tort suits. Plaintiffs can proceed only if an exception applies. The sidewalk exception is one such exception.
-
MCL 691.1402a (Sidewalk exception):
- Municipalities must maintain public sidewalks in reasonable repair.
- They are presumed to have done so unless a plaintiff shows the injury was caused by either (or both) a ≥2-inch vertical discontinuity in the sidewalk or another dangerous condition in the sidewalk itself.
- Whether that presumption is rebutted is a question of law for the court.
- Municipalities may still raise premises defenses, including “open and obvious.”
- “Vertical discontinuity”: A sudden change in elevation or interruption in the smooth, continuous plane of the walking surface (for example, a height differential at a seam or a protrusion sticking up from the slab). In this case, a five-inch protrusion easily met the ≥2-inch threshold.
- “Dangerous condition in the sidewalk itself”: A hazardous condition located in the walking surface, beyond a mere height differential. An embedded metal stub in the pedestrian path is such a condition.
- MCR 2.116(C)(7): A procedural rule allowing dismissal where a claim is barred by immunity. Courts accept complaint allegations as true unless contradicted by the movant’s evidence. Here, immunity did not bar the claim because the object qualified as a sidewalk defect.
- Notice requirement (MCL 691.1402a(2)): Even if a defect exists, a city is not liable unless it knew or should have known of the defect at least 30 days before the injury. This is a separate, critical element for plaintiffs on remand.
- Open and obvious defense (MCL 691.1402a(5)): Municipal defendants may assert common-law premises defenses, including open and obvious. The statute preserves this defense in sidewalk cases, even as the contours of open and obvious have evolved generally in Michigan tort law.
What Remains on Remand
- Whether plaintiff has rebutted the presumption of reasonable repair as a matter of law, given the Court’s classification of the hazard; the statutory text (MCL 691.1402a(4)) makes this a question of law for the court.
- Whether the City had actual or constructive notice of the defect at least 30 days before the incident (MCL 691.1402a(2)).
- Applicability and effect of premises defenses, including open and obvious (MCL 691.1402a(5)), causation, and comparative fault.
- Any damages and remaining factual disputes relevant to liability and defenses.
Conclusion
Mann v. City of Detroit establishes a clear, text-driven rule for sidewalk injuries: an object embedded in and protruding from a paved public sidewalk within the pedestrian pathway constitutes a “defect in the sidewalk” under MCL 691.1402a(3). Such a condition may simultaneously be a ≥2-inch vertical discontinuity and a dangerous condition in the sidewalk itself. The Court’s reading of “paved public sidewalk” confirms that municipal liability is not confined to flaws in pavement material; it extends to embedded hazards that disrupt the walking surface.
While municipalities retain potent defenses—especially the 30-day notice requirement and statutory premises defenses—the opinion meaningfully broadens clarity, if not necessarily liability: embedded protrusions in the path are squarely within the statute. The decision moves Michigan sidewalk law away from fixture-based formalism and toward a functional, pedestrian-safety-focused inquiry grounded in statutory text. For courts and litigants, the touchstones are integration into the walking surface and disruption of pedestrian continuity—not the object’s label as a “fixture.”
In the broader legal context, the ruling aligns with the Legislature’s post-2012 framework imposing a duty to maintain sidewalks and providing defined pathways to rebut the presumption of reasonable repair, while preserving municipalities’ traditional premises defenses. The guidance is practical: if it is embedded in the slab and in the way, it is “in the sidewalk” for MCL 691.1402a.
