The Presumption That Changed Everything — And Then Disappeared

For more than three decades, personal injury attorneys in Louisiana — and their counterparts watching in states across the country — relied on a powerful evidentiary tool known as the Housley Presumption.

Named for the Louisiana Supreme Court's 1991 decision in Housley v. Cerise, the rule was elegant in its simplicity: if a plaintiff was in good health before an accident, developed symptoms shortly after, and no other cause was evident, the court would presume the accident caused the injury. The burden then shifted to the defense to rebut it.

For plaintiffs' attorneys, this was a cornerstone. For defense counsel, it was a wall they had to climb every time.

On May 28, 2025, that wall came down.

WHAT WAS THE HOUSLEY PRESUMPTION?
Under Housley v. Cerise, 579 So.2d 973 (La. 1991), a causation presumption arose when a plaintiff could show all three of the following: 1. They were in good health prior to the accident 2. Symptoms appeared after the accident and continuously manifested thereafter 3. There was a reasonable possibility of causation as established by medical evidence, circumstantial evidence, or common knowledge Once those three elements were met, the burden flipped to the defense. The plaintiff did not need expert testimony proving the accident caused the injury — the law presumed it. Translation: A soft-tissue client with no prior back problems who complains of pain after a rear-end collision? Presumed caused by the crash. Defense had to work to prove otherwise.

How It Unraveled: A Timeline

▶ 1991
Housley v. Cerise Decided
Louisiana Supreme Court establishes the causation presumption. For over three decades, it becomes a bedrock tool for plaintiffs' attorneys statewide — and a closely watched doctrine nationally.
▶ 2020–2024
Repeated Repeal Attempts — All Fail
Louisiana legislators try multiple times to eliminate Housley. Each attempt either stalls or is vetoed. Plaintiffs' attorneys successfully defend the presumption session after session.
▶ April 2025
House Bill 450 Passes Both Chambers
Rep. Michael Melerine (R-Shreveport) introduces HB 450, explicitly designed to overrule Housley. Governor Jeff Landry signals support. The bill passes.
▶ May 28, 2025
Governor Landry Signs HB 450 Into Law
Louisiana Code of Evidence Article 306.1 is enacted. The Housley Presumption is eliminated. The law states: "The lack of a prior history of an illness, injury, or condition shall not create a presumption that an illness, injury, or condition was caused by the act that is the subject of the claim."
▶ May 28, 2025 (SAME DAY)
South Carolina Follows
Governor Henry McMaster signs H. 3430 — South Carolina's sweeping Tort Reform and Liquor Liability Act — eliminating a comparable causation presumption. Effective January 1, 2026.
▶ April 21, 2025
Georgia Joins the Movement
Governor Brian Kemp signs SB 68 and SB 69. SB 68 mandates affirmative expert-supported causation proof, restricts medical damages to amounts actually paid, and allows bifurcated trials separating liability and damages.

What the New Standard Actually Means in Practice

Under the old Housley framework, a plaintiff with no prior history of an injury who developed symptoms after an accident was presumed to have been injured by that accident. The case could often be built around temporal proximity — the timing of symptoms relative to the event.

That is no longer enough.

Under Louisiana's new Article 306.1, the same plaintiff must now present: ✔ Expert medical testimony directly linking the accident to the condition ✔ Diagnostic test results and clinical documentation from early in the treatment timeline ✔ Post-accident medical records showing a documented, continuous progression of symptoms ✔ Affirmative proof of causation — not merely the absence of a prior condition

Temporal proximity alone is no longer enough to carry the burden or defeat summary judgment. Defense counsel can now challenge causation aggressively from the very first filing. In soft-tissue cases, delayed-onset injuries, and claims where the client did not seek immediate care, the exposure gap widens significantly.

IMPORTANT: WHAT ABOUT WORKERS' COMPENSATION?
Louisiana's Article 306.1 carves out workers' compensation claims entirely. The new law expressly does not apply to personal injury claims brought pursuant to the Louisiana Workers' Compensation Law. Workers' comp cases retain their traditional causation standards — for now. However, personal injury attorneys handling third-party claims alongside workers' comp matters need to be acutely aware of where Article 306.1 applies. The standards now diverge, and a claim crossing both tracks requires careful navigation of which evidentiary framework governs which component.

This Isn't Just a Louisiana Story

Louisiana is the most high-profile example — but it is not alone. The erosion of plaintiff-favorable causation presumptions is a national trend, playing out through different mechanisms in different states.

■ Louisiana (2025) | HB 450 / Article 306.1 — Housley Presumption formally eliminated. Effective May 28, 2025. ■ South Carolina (2025) | H. 3430 — Causation presumption eliminated as part of sweeping tort reform. Effective January 1, 2026. ■ Georgia (2025) | SB 68 — Mandates affirmative expert-supported causation proof; restricts medical damages to amounts actually paid; allows bifurcated trials. Effective April 21, 2025. ■ Arkansas (2025) | HB 1204 — Restricts phantom damages and tightens how causation-linked medical expenses are recovered. ■ Florida (2023) | HB 837 — Shifted to modified comparative fault; medical damages tied to amounts actually paid with major causation strategy implications. ■ Iowa / Montana / North Carolina | Earlier-generation reforms restricting causation-linked damage recovery — the blueprint others are now following.

The "Double Whammy" Every PI Attorney Needs to Understand

Louisiana did not just eliminate the Housley Presumption in isolation. It paired that change with another major reform happening simultaneously across the country: the restriction of medical damages to amounts actually paid rather than amounts billed.

THE DOUBLE WHAMMY
1. Causation is harder to prove Expert testimony required from the outset. No presumption to lean on. Temporal proximity alone no longer carries the burden or defeats summary judgment. 2. Medical damages are lower Even when causation is established, the damages ceiling is tied to negotiated insurance rates — not billed totals. The ceiling dropped. The floor got harder to reach. In soft-tissue cases, delayed-onset injury claims, and matters where the client had any prior related condition at all, the combined effect of these two reforms compresses case value from both ends simultaneously.
CRITICAL FOR ATTORNEYS: THE TRANSITION DATE MATTERS
Article 306.1 applies prospectively only. Claims arising before May 28, 2025 may still invoke the Housley Presumption. For cases involving: • Multiple accidents crossing the May 28, 2025 effective date • Progressive symptoms that developed over time • Course of treatment beginning before and continuing after the effective date ...courts will need to determine whether the injury is divisible and which standard governs which component. This transitional landscape is actively being litigated. Attorneys with cases in this gray zone should monitor developing case law closely and document every phase of the injury timeline with precision.

What This Means for How You Build Cases Right Now

Here is the bottom line for every personal injury attorney, regardless of which state you practice in: the evidentiary safety net is gone in a growing number of jurisdictions — and where it still exists, it is under active legislative threat.

What replaces it is documentation. Specifically, the kind that cannot be reconstructed six months after the fact: ■ Dated, consistent records of symptoms appearing shortly after the incident ■ Documented functional limitations and daily life disruption in the client's own words ■ A continuous, uninterrupted timeline that makes the causal link impossible to credibly dispute ■ Real-time evidence of pain patterns, sleep disruption, activity restriction, and emotional impact

Defense counsel's new first move in a post-Housley world is to find the gaps — the weeks where your client didn't see a doctor, the periods with no recorded symptoms, the inconsistencies between what the client says now and what the record shows from then.

MyInjuryTracker was built specifically for this moment. Every weekly check-in your client completes creates a dated, time-stamped, legally defensible entry in the record. Pain levels. Sleep disruption. Activity limitations. Mood. Medication. Daily life impact. All documented in real time, in the client's own words, through a process they can actually complete.

When the defense attorney looks for gaps, they won't find them. When the expert needs a continuous symptom history to support their opinion, it's already there. When the case goes to trial and opposing counsel tries to argue that the plaintiff's complaints are recent fabrications, you have 52 weeks of contemporaneous documentation that says otherwise.

The Bottom Line

The Housley Presumption gave Louisiana plaintiffs' attorneys a procedural advantage for 34 years. That advantage is gone. Georgia and South Carolina followed. More states are watching.

The attorneys who adapt fastest will be the ones who understand that documentation is no longer just a good practice — it's the new foundation of a viable personal injury case.

The evidentiary net is gone. The documentation has to replace it.
