The sole-cause argument
Public entities routinely argue a private third party's conduct was the sole cause, breaking the causal chain to the entity's own negligence.
Dangerous Condition Industrial California Public Entity Claims
Dangerous condition industrial California claims, and public entity liability litigation generally, present procedural and substantive hurdles that do not exist against private defendants. Success depends on early attention to the government-claim deadline, a clear strategy for defeating design immunity, and a thorough investigation into what the entity actually knew about the hazard before the injury.

Government Claim Requirements and Notice
Before suing a California public entity, a claimant must present a formal government claim, usually within six months of the injury. Missing it can be fatal, so every potentially responsible entity and its deadline must be identified at the outset. Under Government Code section 835, the claimant must then show actual or constructive notice of the dangerous condition in time to have protected against it. Investigating notice means securing the entity's complaint logs, prior incident reports, maintenance and inspection records, and internal engineering studies going back as far as retention allows.
Defeating Design Immunity
Design immunity is powerful but limited. The entity must prove a causal relationship between the design and the injury, discretionary approval by an employee with authority, and substantial evidence that the design was reasonable when approved. A claimant defeats it by showing the approval was not truly discretionary, that changed conditions since approval created new dangers the design never anticipated, or that no reasonable official could have approved the design on the evidence then before them.
Building the Case Despite a Third-Party Tortfeasor
California rejects the all-or-nothing framing
An entity can share responsibility for a dangerous condition even when a third party's independent negligence also contributed, provided the dangerous condition was a substantial factor in causing the harm.
Why record retention matters
Notice evidence often depends on historical complaint and incident records, so understanding how far back the entity's records go defines the realistic scope of discovery.

What is the deadline to file a government claim in California?
For most personal injury claims against a California public entity, a formal government claim must be presented within six months of the injury, and missing this deadline can bar the claim entirely.
What must a public entity prove to establish design immunity?
A causal relationship between the design and the injury, discretionary approval of the design by an authorized employee, and substantial evidence supporting the reasonableness of the design at the time it was approved.
Can a public entity be held liable if a third party's negligence also caused the injury?
Yes. California law allows a public entity to share responsibility for a dangerous condition even when a third party's independent negligence contributed to the injury, as long as the dangerous condition was a substantial factor in causing the harm.
