We turn first to the question of whether a row of trees can be a "fence or other structure in the nature of a fence" within the meaning of section 841.4.
[1] [2] [3] *1306 "Our fundamental task in construing a statute is to ascertain the intent of the lawmakers so as to effectuate the purpose of the statute. [Citation.] We begin by examining the statutory language, giving the words their usual and ordinary meaning. [Citation.] If there is no ambiguity, then we presume the lawmakers meant what they said, and the plain meaning of the language governs. [Citations.] If, however, the statutory terms are ambiguous, then we may resort to extrinsic sources, including the ostensible objects to be achieved and the legislative history." (Day v. City of Fontana (2001) 25 Cal.4th 268, 272, 105 Cal.Rptr.2d 457, 19 P.3d 1196.)
In construing the spite fence statute, we are bound by the rule of liberal construction that applies to the Civil Code. "The rule of the common law, that statutes in derogation thereof are to be strictly construed, has no application to this code. The code establishes the law of this state respecting the subjects to which it relates, and its provisions are to be liberally construed with a view to effect its objects and to promote justice." (Civ.Code, § 4.) Thus, the question for us to decide is whether, liberally construing the spite fence statute with a view to effecting its objects, a row of trees may be deemed a "fence or other structure in the nature of a fence" within the meaning of that statute.
[4] The Handleys take the position, which the trial court apparently adopted, that a row of trees cannot be a "structure in the nature of a fence" because "[t]rees are not a 'structure.' " According to the Handleys, "[a] structure, by definition, is a **267 'thing built or constructed, as a building or dam,' " and trees are grown, not built or constructed. We do not dispute that trees grow. The question, however, is not whether a single growing tree can be a structure, but whether a row of growing trees can be a structure. We conclude that it can.
Defined broadly, a "structure" is "something arranged in a definite pattern of organization." (Merriam-Webster's Collegiate Dict. (10th ed.2000) p. 1163, col. 2.) Under this broad definition, a row of trees, arranged in a line by the person who planted them, could easily constitute a "structure." The Handleys would have us apply a narrower definition of the word "structure," as "something constructed or built." (Webster's New International Dict. (2d. ed 1938) p. 2501, col. 1.) Even if we apply that narrower definition, however, we conclude a row of trees may be a "structure."
To "construct" something is to "put together [its] constituent parts ... in their proper place and order." (Webster's New International Dict. (2d. ed 1938) p. 572, col. 3.) Although, to paraphrase a famous poem, only God can construct a *1307 tree, [FN2] any enterprising individual with a shovel and some saplings can construct a row of trees by simply planting the saplings in their proper place and order--in other words, in a row. Because a row of trees can be constructed, a row of trees can be a "structure" even within the narrower definition of that word the Handleys advocate.
FN2. Kilmer (1914) "Trees."
The question that remains is whether a row of trees can be a structure "in the nature of a fence." The Handleys suggest it cannot because "[a] line of unconnected trees cannot prevent intrusion nor straying from within." While it is true one definition of the word "fence" is "an enclosing structure ... intended to prevent intrusion from without or straying from within" (Black's Law Dict. (5th ed.1979) p. 556, col. 2), a "fence" can also be a "structure ... erected ... to separate two contiguous estates" (ibid.) or "a barrier intended ... to mark a boundary" (Merriam-Webster's Collegiate Dict. (10th ed.2000) p. 428, col. 1). In light of the history and purpose of the spite fence statute, we conclude these latter definitions more accurately express what constitutes a "fence or other structure in the nature of a fence" within the meaning of section 841.4.
The rise of spite fence statutes in the United States stems from the general repudiation in this country of the English doctrine of "ancient lights," under which a landowner could acquire an easement over adjoining property for the passage of light and air. (See Western etc. Co. v. Knickerbocker (1894) 103 Cal. 111, 113, 37 P. 192; Venuto v. Owens-Corning Fiberglas Corp. (1971) 22 Cal.App.3d 116, 127, 99 Cal.Rptr. 350.) "Such a doctrine was ill-suited to conditions existing in the early part of this century in a new and rapidly growing country. At that time society had a significant interest in encouraging unrestricted land development. Moreover a landowner's rights to use his land were virtually unlimited; it was thought that he owned to the center of the earth and up to the heavens. In contrast, light had little social importance beyond its value for aesthetic enjoyment or illumination." (Sher v. Leiderman (1986) 181 Cal.App.3d 867, 876, 226 Cal.Rptr. 698.)
Under American common law, it was said that "a man has a right to build a fence on his own land as high as he pleases, however much it may obstruct his neighbor's light and air." **268 (Rideout v. Knox (1889) 148 Mass. 368, 372, 19 N.E. 390, 391.) Thus, in the 1870's, when Charles Crocker sought to purchase an entire city block on San Francisco's Nob Hill on which to build a mansion, and a local undertaker named Yung would not sell his small lot to Crocker, Crocker bought the remainder of the block and built a fence 40 feet high on his property around Yung's lot. (Lewis, The Big Four (1951) pp. 111, 118-119.) Eventually, Yung sold out and Crocker procured the entire block.
*1308 In the 1880's, however, courts and legislatures began addressing the issue of whether a fence like Crocker's, built unnecessarily high, simply to spite a neighbor, could be deemed a private nuisance subject to abatement. (See Comment, Torts: Spite Fence (1917) 5 Cal. L.Rev. 177.) In 1887, Massachusetts enacted one of the earliest "spite fence" statutes in the United States, expressly declaring such fences a private nuisance. (See Rideout v. Knox, supra, 148 Mass. 368, 19 N.E. at p. 391, citing Mass. Gen. Laws ch. 348, § 1 (1887) [now codified as Mass. Ann. Laws ch. 49, § 21] (Law. Co-op 1993).) Other states followed suit. (See, e.g., Ind.Code Ann. § 32-10-10- 1 (West 2001); Me.Rev.Stat. Ann. tit. 17, § 2801 (West 1964); N.H.Rev.Stat. Ann. § 476:1 (1955); R.I. Gen. Laws § 34-10-1 (1956); Wis. Stat. Ann. § 844.10 (West 1994).) Meanwhile, beginning in 1888, courts in some states began to hold that a fence erected for no purpose except to harm a neighbor could be abated as a nuisance under the common law. (See Burke v. Smith (1888) 69 Mich. 380, 37 N.W. 838; Annot., Spite fences and other spite structures (1941) 133 A.L.R. 691, 692-697, § II.a., and cases cited.)
In California, a predecessor to the current spite fence statute regulating the height of division fences and partition walls in cities and towns was enacted in 1885. (Stats.1885, ch. XXXIX, p. 45.) Under this earlier law, a landowner could not build a fence or partition wall more than 10 feet high without obtaining a permit from the board of supervisors or the city council, and the governmental entity could not grant the permit unless the landowner secured the written consent of the owner or occupant of the adjoining property affected by the proposed fence or wall. (See Western etc. Co. v. Knickerbocker, supra, 103 Cal. at p. 114, 37 P. 192.) The California Supreme Court concluded that if the Legislature intended the law to apply to a structure built entirely on the landowner's property, it was unconstitutional because it was not "competent for the legislature to vest in [a landowner] the power to prevent his neighbor from building such structure as he pleases, provided it is not a nuisance, and it is not such merely because it obstructs the passage of light and air." (Id. at p. 115, 37 P. 192.) Accordingly, to render the law constitutional, the court construed it as applying only to fences built on the boundary line and thus resting partly on the land of the adjoining owner. (Id. at p. 116, 37 P. 192.)
In 1913, the Legislature joined a growing number of states and adopted the current spite fence statute, which was likely drawn from the Massachusetts statute, declaring it a private nuisance to maliciously erect or maintain "[a]ny fence or other structure in the nature of a fence, unnecessarily exceeding ten feet in height ... for the purpose of annoying the owner or occupants of adjoining property, ..." (Stats.1913, ch. 197, § 1, p. 342.) The statute was upheld against constitutional challenge in 1920. (Bar Due v. Cox (1920) 47 Cal.App. 713, 716, 190 P. 1056.) The spite fence statute *1309 remained uncodified until 1953, when it was codified as section 841.4 of the Civil Code. (Stats.1953, ch. 37, § 2, p. 674.)
