California Demurrer — Other Claims

IIED requires conduct so extreme and outrageous that it exceeds all bounds of decency tolerated in a civilized society. The standard is high but the Garcia ruling illustrates that surveillance combined with physical threats, attempted kidnapping, and ongoing harassment clears the bar at the pleading stage — the court's job on demurrer is only to assess whether, if true, the conduct would qualify.

If you're the moving party: Argue that the alleged conduct, even if true, is not qualitatively different from ordinary harassment, dispute conduct, or aggressive business tactics that California courts have refused to characterize as "outrageous." The strongest demurrer targets are standalone verbal confrontations or single-incident claims without a course of conduct.

If you're the opposing party: Plead the course of conduct with specificity: duration, escalation, multiple incidents, the power differential between parties, the defendant's knowledge of plaintiff's vulnerability, and any contemporaneous threat of physical harm. Pattern conduct over time is consistently more vulnerable to the outrageous-conduct finding than isolated incidents.

When the contractual obligation is triggered by the landlord's knowledge of a condition — e.g., a duty to repair that arises only after notice — the complaint must allege actual or constructive notice. A complaint that pleads breach of a knowledge-contingent duty without pleading that defendant knew or should have known of the triggering condition is facially deficient.

If you're the moving party: Identify the specific contractual provision at issue and argue that it is knowledge-contingent. Show that the complaint alleges the breach without alleging how or when the defendant became (or should have become) aware of the condition. This is particularly strong in cases involving latent defects or conditions requiring specific inspection.

If you're the opposing party: Plead the notice facts: when the condition arose, when plaintiff first observed it, how and when plaintiff communicated it to the landlord (demand letter, oral notice, maintenance request), and that defendant had sufficient time to respond before the breach occurred. Where constructive notice is the theory, plead the facts that should have triggered the landlord's awareness (e.g., visible water damage, repeated complaints from other tenants).

Private nuisance requires more than a technical interference — the complaint must plead substantial actual damage and facts showing the interference was unreasonable in nature, duration, and amount. San Diego Gas & Electric sets the floor: a trivial annoyance is not actionable.

If you're the moving party: Challenge both elements. "Substantial damage" requires more than the general allegation that plaintiff was "disturbed" or "inconvenienced" — the complaint must identify the harm in terms the court can assess. "Unreasonable interference" requires facts about the nature, duration, and severity of the condition.

If you're the opposing party: Plead the specific harm (health impacts, property damage, inability to use portions of the premises), duration (continuous vs. sporadic), and the qualitative nature of the interference. Dollar amounts for property damage or medical treatment strengthen the substantial-damage showing.

Whether a state-law claim against a licensed health care service plan is preempted by Knox-Keene, which provides no general private right of action.

Knox-Keene (Health & Safety Code § 1340 et seq.) comprehensively regulates health care service plans in California. A common-law or UCL claim that is effectively an enforcement action for a Knox-Keene violation is preempted by the Act's administrative enforcement scheme. Knox-Keene does not provide a general private right of action; the remedies are those the statute itself specifies.

If you're the moving party: Identify the Knox-Keene provision the defendant allegedly violated and argue the common-law claim is governed exclusively by the administrative scheme. Blue Cross of California v. Superior Court and California Medical Ass'n v. Aetna support the preemption framework. Show the claim is essentially asking a court to enforce a Knox-Keene obligation through tort or UCL rather than through the DMHC.

If you're the opposing party: Distinguish claims within Knox-Keene's scope from claims resting on independent legal duties. A reimbursement claim grounded in Welfare and Institutions Code provisions governing Medi-Cal managed care — or a contractual obligation arising outside Knox-Keene — is not preempted. County of Santa Clara v. Superior Court (2023) holds that Medi-Cal managed care reimbursement obligations are independent of Knox-Keene. Plead the independent statutory or contractual basis clearly.

Primary sources: Health & Safety Code § 1340 et seq.; Blue Cross of California v. Superior Court (1998) 67 Cal.App.4th 42; County of Santa Clara v. Superior Court (2023) 84 Cal.App.5th 1.

Corpus signal: moderate — Quickmed v. L.A. Care Health Plan (LA Superior, Mosk Dept 515, May 5, 2026) sustained negligence count and several others on Knox-Keene preemption grounds; quantum meruit overruled on independent Santa Clara statutory basis.

ERISA preempts state-law claims that "relate to" an employee benefit plan. On demurrer, however, preemption must be apparent from the face of the complaint — the court looks at what the plaintiff alleged, not at what the defendant asserts about the plan's structure. A complaint that does not reference an ERISA plan, employer-sponsored benefits, or ERISA-governed claims is not subject to ERISA preemption on demurrer.

If you're the moving party: Show that the complaint itself references ERISA-plan benefits, employer-sponsored coverage, or ERISA-governed claims processing. If the plaintiff has carefully avoided those references, ERISA preemption is not available at the pleading stage — it becomes a summary judgment issue after discovery.

If you're the opposing party: Draft the complaint without reference to the ERISA plan structure where the theory does not require it (e.g., plead the statutory reimbursement obligation directly; avoid language like "employer-sponsored plan" or "plan benefits"). ERISA preemption is a fact-intensive inquiry and does not belong on demurrer absent facial allegations that establish plan status.

The duty of loyalty is a recognized employee obligation during employment — disclosure of trade secrets, solicitation of co-workers during employment, and working for a competitor without consent can all constitute a breach. Breach-of-loyalty claims fare better on demurrer than interference claims in the cross-complaint context because they do not require a contract to interfere with.

If you're the moving party: The challenge is usually damages: a breach-of-loyalty claim requires the employer to plead and eventually prove actual damages from the breach, not merely that the employee was disloyal. Target the damages pleading if the complaint only alleges disloyalty without specifying harm.

If you're the opposing party: Distinguish the time period: the duty of loyalty runs only while employed, not after. Post-employment solicitation or competition is governed by the non-solicitation/non-compete framework (and in California, post-employment non-solicitation of customers is unenforceable under Bus. & Prof. Code § 16600 post-Edwards). Narrow the demurrer to the post-employment conduct if the complaint conflates the two.
