California Civil Jury Instructions CACI

2022 Private Nuisance—Balancing-Test Factors—Seriousness of Harm and Public Benefit


In determining whether the seriousness of the harm to [name of plaintiff] outweighs the public benefit of [name of defendant]’s conduct, you should consider a number of factors.

To determine the seriousness of the harm [name of plaintiff] suffered, you should consider the following:

a.The extent of the harm, meaning how much the condition [name of defendant] caused interfered with [name of plaintiff]’s use or enjoyment of [his/her/nonbinary pronoun] property, and how long that interference lasted.

b.The character of the harm, that is, whether the harm involved a loss from the destruction or impairment of physical things that [name of plaintiff] was using, or personal discomfort or annoyance.

c.The value that society places on the type of use or enjoyment invaded. The greater the social value of the particular type of use or enjoyment of land that is invaded, the greater is the seriousness of the harm from the invasion.

d.The suitability of the type of use or enjoyment invaded to the nature of the locality. The nature of a locality is based on the primary kind of activity at that location, such as residential, industrial, or other activity.

e.The extent of the burden (such as expense and inconvenience) placed on [name of plaintiff] to avoid the harm.

To determine the public benefit of [name of defendant]’s conduct, you should consider:

a.The value that society places on the primary purpose of the conduct that caused the interference. The primary purpose of the conduct means [name of defendant]’s main objective for engaging in the conduct. How much social value a particular purpose has depends on how much its achievement generally advances or protects the public good.

b.The suitability of the conduct that caused the interference to the nature of the locality. The suitability of the conduct depends upon its compatibility to the primary activities carried on in the locality.

c.The practicability or impracticality of preventing or avoiding the invasion.


Directions for Use

This instruction must be given with CACI No. 2021, Private Nuisance—Essential Factual Elements. (See Wilson v. Southern California Edison Co. (2015) 234 Cal.App.4th 123, 160−165 [184 Cal.Rptr.3d 26].) CACI No. 2021 has been found to be inadequate to express the requirement that the plaintiff must suffer serious harm without this additional guidance to the jury on how to determine whether the seriousness of the plaintiff’s harm outweighs the public benefit of the defendant’s conduct (CACI No. 2021, element 8). (See Id. at pp. 162−163.)


Sources and Authority

“ ‘The interference with the protected interest must not only be substantial, but it must also be unreasonable’, i.e., it must be ‘of such a nature, duration or amount as to constitute unreasonable interference with the use and enjoyment of the land.’ The primary test for determining whether the invasion is unreasonable is whether the gravity of the harm outweighs the social utility of the defendant’s conduct, taking a number of factors into account. Again the standard is objective: the question is not whether the particular plaintiff found the invasion unreasonable, but ‘whether reasonable persons generally, looking at the whole situation impartially and objectively, would consider it unreasonable.’ And again this is a question of fact: ‘Fundamentally, the unreasonableness of intentional invasions is a problem of relative values to be determined by the trier of fact in each case in the light of all the circumstances of that case.’ ” (San Diego Gas & Electric Co. v. Superior Court (1996) 13 Cal.4th 893, 938–939 [55 Cal.Rptr.2d 724, 920 P.2d 669], internal citations omitted.)

“Had the jury been instructed on the proper factors to consider when weighing the gravity of the harm against the social utility of [defendant]’s conduct and found [defendant] liable, the statement of these elements would be sufficient because in finding in favor of [plaintiff] the jury necessarily would have concluded that the harm was substantial. Without such instruction, it is not.” (Wilson, supra, 234 Cal.App.4th at p. 163.)

Restatement Second of Torts, section 827 provides:

(a)the extent of the harm involved;

(c)the social value that the law attaches to the type of use or enjoyment invaded;

(d)the suitability of the particular use or enjoyment invaded to the character of the locality; and

(e)the burden on the person harmed of avoiding the harm.

Restatement Second of Torts, section 828 provides:

(a)the social value that the law attaches to the primary purpose of the conduct;

(b)the suitability of the conduct to the character of the locality; and
