Defeating Summary Judgment in Delayed-Care Premises Cases

A practical analysis for plaintiff’s counsel

Delayed-care premises cases are summary judgment magnets. The defense’s playbook is the same in every one of them: no duty, no breach, no causation. The trial court agrees and the case is over before a jury sees a single fact.

The Fourth District Court of Appeal’s treatment of O’Malley v. Diamond Resorts — the case that produced the $60 million Orange County verdict in January 2022, a final paid judgment over $100 million after CCP § 998 enhancements and post-judgment interest, and a unanimous appellate affirmance in November 2023 (G061459) — provides a working roadmap for defeating the defense MSJ. This page lays out the roadmap.

The defense’s standard summary judgment template

In a delayed-care welfare-check case, the defense MSJ almost always has three sections, in this order:

Section I — No duty. “Defendant owed no duty to render aid to plaintiff. There is no special relationship that triggers an affirmative duty to render aid. The phone call from plaintiff’s spouse did not create a duty as a matter of law.”

Section II — No breach. “Even assuming a duty, defendant did not breach it. The staff member entered the room and looked. That is a reasonable response.”

Section III — No causation. “Even assuming duty and breach, plaintiff cannot prove causation. The injury was caused by the underlying medical condition, not by anything defendant did or failed to do. Plaintiff would have suffered the same harm regardless.”

This template loses under the O’Malley roadmap. Here is how.

Section I — Demolishing the “no duty” argument

The defense’s no-duty argument depends on the court accepting that the only available source of duty is a pre-existing special relationship. The plaintiff’s response is to attack this assumption from two directions:

Direction one: special relationship exists. Hotels owe innkeeper duties to their guests. These duties include the duty to render or summon aid when a guest is in known peril. Cite the line of California cases extending back through the 19th century recognizing the innkeeper-guest special relationship.

Direction two: negligent undertaking creates duty independently. Even if no special relationship existed, the hotel voluntarily undertook to perform the welfare check. Under Artiglio v. Corning Inc., 18 Cal. 4th 604 (1998), and Restatement (Second) of Torts § 324A, that voluntary undertaking creates a duty regardless of whether one existed beforehand. The hotel cannot disclaim a duty it created by agreeing to perform the very task at issue.

The O’Malley appellate decision affirms the second approach. A phone call from a family member, accepted by the front desk, with a deployment of staff in response, is a sufficient undertaking to create duty as a matter of law — or, at minimum, to create a triable issue of fact precluding summary judgment.

Section II — Demolishing the “no breach” argument

The defense will argue that what the staff member did was reasonable. The plaintiff’s response is to make the hotel’s own policy the standard, not the staff member’s after-the-fact testimony.

Step one: produce the policy. The welfare-check policy. The training manual. The corporate procedures memorandum. Whatever document the hotel uses internally to describe what a welfare check is supposed to look like.

Step two: catalog the deviations. Every place the actual response departed from the policy. Number of responders. Training of responders. Documentation. Inspection thoroughness. Communication with the requesting party. Escalation triggers.

Step three: brief breach as a matter of fact. “There is at minimum a triable issue of fact as to whether sending [one untrained maintenance worker] to perform a task the written policy explicitly required [two trained employees] to perform constitutes reasonable care.”

Defense counsel will respond that the policy is “aspirational” or “non-binding.” The plaintiff’s reply: corporate designee testimony admitting otherwise (which is almost always obtainable in deposition), or, failing that, the absence of any document calling the policy aspirational. A policy is what it says it is. The defendant has the burden to prove otherwise.

In O’Malley, this is the move the appellate court endorsed. The deviation from the written policy was sufficient to create a triable issue on breach.

Section III — Demolishing the “no causation” argument

This is where most plaintiffs lose if they are not careful. The defense will argue that the underlying medical event caused the injury, and that nothing the defendant did mattered.

The plaintiff’s response is § 324A(a) — increased risk of harm:

The plaintiff need not prove that the defendant caused the original medical event. The plaintiff must prove that the defendant’s conduct increased the risk that the original event would result in the harm ultimately suffered.

This standard is significantly lower than but-for causation. The plaintiff needs to show that timely intervention would have led to a materially better outcome — not that the entire injury would have been prevented.

The supporting evidence:

Treating physician testimony. The neurologist or neurosurgeon who treated the plaintiff can testify, generally, to the time-sensitivity of the condition and the prognosis differential between timely and delayed intervention. This testimony does not require a precise temporal counterfactual; it requires a directional statement of differential outcome.

Retained medical expert. A board-certified expert in the relevant specialty (neuroendovascular surgery, emergency medicine) can testify to the standard of care for the underlying medical condition and the impact of delay on outcomes.

Hospitality standards expert. A hospitality-operations expert can testify to the standard of care for hotel welfare checks and to the deviation in the specific case.

Together, these three create a chain that satisfies § 324A(a) and forecloses summary judgment on causation.

The O’Malley decision implicitly approves this framework by reversing summary judgment on a record that featured exactly this evidentiary structure.

Specific opposition brief structure

A working structure for the opposition brief:

Introduction (1–2 pages). State the case in a sentence — what the defendant did, what the consequence was, why summary judgment is improper.

Statement of Disputed Facts. Track the defendant’s separate statement, but lead with the facts that hurt the defense — the written policy, the deviation from it, the corporate designee admissions, the medical evidence of delay-driven harm.

Argument Section I — Duty. Negligent undertaking framework. Cite Artiglio, § 324A, and O’Malley v. Diamond Resorts, G061459 (4th App. Dist., affirmed November 2023). Even where the appellate opinion’s citability is constrained by publication status, the case caption, the published Daily Journal coverage of both the trial and the affirmance, and the underlying record provide ample persuasive authority. Cite the opinion’s specific holding on Michael O’Malley’s non-undertaking and on comparative negligence.

Argument Section II — Breach. The hotel’s own policy as the standard. Documentary support. Triable issues created by the deviation from the policy.

Argument Section III — Causation. § 324A(a) increased-risk theory. Treating physician testimony, retained expert testimony, hospitality expert testimony. Why this satisfies the summary judgment standard.

Conclusion. Cite the appellate reversal in O’Malley as proof that summary judgment in this fact pattern is reversible error.

Practical tactical notes

File a cross-motion for summary adjudication of duty. In strong cases, the plaintiff can move for summary adjudication of duty as a matter of law, putting the defendant in the position of defending its own policy at the pleading stage. This often produces favorable settlement movement.

Use the corporate designee depositions before opposing the MSJ. Schedule corporate designee depositions on policy interpretation, training, and incident-response protocols early. Use the deposition transcripts as exhibits to the opposition.

Anchor every key fact to a document. Summary judgment is a paper proceeding. Every assertion in the opposition should be backed by a document, not just by plaintiff testimony. The hotel’s own policy is the most powerful document in the file.

Treat the appellate posture as leverage. A defense lawyer who knows the case will go up to the Court of Appeal on a granted MSJ — and that O’Malley was unanimously affirmed at the Fourth District — will think harder about pressing the motion in the first place. Make this clear in meet and confer.

Pair the opposition with a CCP § 998 offer. While the MSJ is pending or being briefed is an opportune moment to lock in pre-judgment interest exposure on the defense. In O’Malley, an early-served § 998 offer added roughly $30 million to the final judgment when the verdict came in above the offer. The § 998 framework is covered in detail in the companion brief on § 998 strategy.

Frequently Asked Questions

What is the defense’s typical summary judgment template in a delayed-care case?

Three sections, in order: (1) no duty, (2) no breach, (3) no causation. The plaintiff’s opposition should attack each section using the O’Malley v. Diamond Resorts framework — negligent undertaking creates duty, the defendant’s own policy supplies the standard for breach, and § 324A(a) increased-risk theory satisfies causation without requiring a precise temporal counterfactual.

How does a plaintiff prove duty in a delayed-care premises case?

Two paths, used together. First, the special-relationship duty owed by hotels (innkeepers) to guests. Second, and more powerful, the negligent undertaking doctrine — once the defendant voluntarily agreed to act, it owed a duty to act with reasonable care. O’Malley v. Diamond Resorts confirms both paths.

How do you defeat the “no causation” argument at summary judgment?

Use § 324A(a) increased-risk theory. The plaintiff doesn’t need to prove the defendant caused the underlying medical event. The plaintiff needs treating-physician testimony plus retained-expert testimony showing that timely intervention would have led to a materially better outcome. This framework survived appellate scrutiny in O’Malley — the Fourth District unanimously affirmed against a direct causation challenge.

Can I file a cross-motion for summary adjudication of duty?

Yes, in strong cases. Moving for summary adjudication of duty as a matter of law puts the defense in the position of defending its own policy at the pleading stage, often producing favorable settlement movement.

Should I pair the MSJ opposition with a CCP § 998 offer?

Often, yes. Serving a § 998 offer while the MSJ is pending starts the pre-judgment interest clock running. In O’Malley, an early-served § 998 offer added roughly $30 million to the final judgment when the verdict came in above the offer. The combination of a strong MSJ opposition plus a § 998 offer can drive substantial settlement movement.
