On December 11, 1982, defendant Episcopal Community Services in Arizona (ECS) opened the St. Martin’s Center (Center) in Tucson. The Center’s only purpose is to provide one free meal a day to indigent persons. Plaintiff Armory Park Neighborhood Association (APNA) is a non-profit corporation organized for the purpose of “improving, maintaining and insuring the quality of the neighborhood known as Armory Park Historical Residential District.” The Center is located on Arizona Avenue, the western boundary of the Armory Park district. On January 10, 1984, APNA filed a complaint in Pima County Superior Court, seeking to enjoin ECS from operating its free food distribution program. The complaint alleged that the Center’s activities constituted a public nuisance and that the Armory Park residents had sustained injuries from transient persons attracted to their neighborhood by the Center.
The superior court held a hearing on APNA’s application for preliminary injunction on March 6 and 7, 1984. At the commencement of the hearing, the parties stipulated that
... there is no issue concerning any State, County, or Municipal zoning ordi *3 nance, or health provision, before the Court. And, the Court may find that defendants are in compliance with the same.
The residents then testified about the changes the Center had brought to their neighborhood. Before the Center opened, the area had been primarily residential with a few small businesses. When the Center began operating in December 1982, many transients crossed the area daily on their way to and from the Center. Although the Center was only open from 5:00 to 6:00 p.m., patrons lined up well before this hour and often lingered in the neighborhood long after finishing their meal. The Center rented an adjacent fenced lot for a waiting area and organized neighborhood cleaning projects, but the trial judge apparently felt these efforts were inadequate to control the activity stemming from the Center. Transients frequently trespassed onto residents’ yards, sometimes urinating, defecating, drinking and littering on the residents’ property. A few broke into storage areas and unoccupied homes, and some asked residents for handouts. The number of arrests in the area increased dramatically. Many residents were frightened or annoyed by the transients and altered their lifestyles to avoid them. 1
Following the hearing, ECS filed a motion to dismiss the complaint based on three grounds: 1) that compliance with all applicable zoning and health laws constituted a complete defense to a claim of public nuisance; 2) that there had been no allegation or evidence of a violation of a criminal statute or ordinance, which it argues is a prerequisite to a finding of public nuisance; and 3) that APNA lacked standing to bring an action to abate a public nuisance because it had neither pled nor proved any special injury differing in kind and degree from that suffered by the public generally.
Based on the hearing testimony, the trial court granted the preliminary injunction and denied ECS’ motion to dismiss. In its order, the court noted that ECS could be enjoined because its activities constituted both a public and a private nuisance. After its motion for reconsideration was denied, ECS filed a special action 2 in the court of appeals, and shortly thereafter filed a notice of appeal from the order granting the injunction. The court of appeals consolidated the proceedings and stayed enforcement of the trial court’s order pending a final decision.
A divided court of appeals reversed the trial court’s order. In the view of the majority, a criminal violation was a prerequisite to a finding of public nuisance; because plaintiff had alleged no criminal violation, the injunction was improperly granted. The majority also concluded that the trial court abused its discretion by finding both a public and a private nuisance when the plaintiff had not alleged a private nuisance. Finally, the court held that compliance with zoning provisions was a complete defense. The court vacated the order for preliminary injunction and remanded the matter to the trial court with directions to grant ECS’ motion to dismiss. We have jurisdiction pursuant to Rule 23, Ariz.R. Civ.App.P., 17A A.R.S., A.R.S. § 12-120.24, and Rule 8(b), Ariz.R.P.Sp.Act; 17A A.R.S. We granted review in this case because of the importance of the following questions:
1) When does a voluntary association have standing to bring an action for public nuisance on behalf of its members?
2) May a lawful business be enjoined for acts committed off its premises by clients who are not under its control or direction?
3) Is it necessary to plead and prove a zoning or criminal violation by the defendant, or may a lawful activity be enjoined because the manner in which it is conducted is unreasonable and therefore constitutes a public nuisance?
*4 THE CONCEPT OF “NUISANCE”
Now considered a tort, a public nuisance action originated in criminal law. Early scholars defined public nuisance as “an act or omission ‘which obstructs or causes inconvenience or damage to the public in the exercise of rights common to all her Majesty’s subjects.’” PROSSER, W. AND W.P. KEETON, HANDBOOK ON THE LAW OF TORTS, § 90, at 643 (5th ed. 1984), quoting Stephen, General View of the Criminal Law in England 105 (1890). The sole remedy was criminal prosecution. PROSSER, supra, § 86, at 618.
Historically, the remedy for a private nuisance was an action “upon the case,” as it was an injury consequential to the act done and found its roots in civil law. PEARCE, E. AND D. MESTON, HANDBOOK ON THE LAW RELATING TO NUISANCES 2 (1926). A private nuisance is strictly limited to an interference with a person’s interest in the enjoyment of real property. The Restatement defines a private nuisance as “a nontrespassory invasion of another’s interest in the private use and enjoyment of land.” RESTATEMENT (SECOND) OF TORTS § 821D. A public nuisance, to the contrary, is not limited to an interference with the use and enjoyment of the plaintiff’s land. It encompasses any unreasonable interference with a right common to the general public. RESTATEMENT, supra, § 821B. Accord, PROS-SER, supra, § 86, at 618.
We have previously distinguished public and private nuisances. In
City of Phoenix v. Johnson,
The defendant contends that the trial court erred in finding both public and private nuisances when the plaintiff had not asserted a private nuisance claim. The defendant has read the trial court’s minute entry too strictly. While we acknowledge that public and private nuisances implicate different interests, we recognize also that the same facts may support claims of both public and private nuisance. As Dean Prosser explained:
When a public nuisance substantially interferes with the use or enjoyment of the plaintiff’s rights in land, it never has been disputed that there is a particular kind of damage, for which the private action will lie. Not only is every plot of land traditionally unique in the eyes of the law, but in the ordinary case the class of landowners in the vicinity of the alleged nuisance will necessarily be a limited one, with an interest obviously different from that of the general public. The interference itself is of course a private nuisance; but is none the less particular damage from a public one, and the action can be maintained upon either basis, or upon both. (Citations omitted.)
Prosser, Private Action for Public Nuisance, 52 Va.L.Rev. 997, 1018 (1966).
Thus, a nuisance may be simultaneously public and private when a considerable number of people suffer an interference with their use and enjoyment of land.
See Spur Industries,
STANDING TO BRING THE ACTION
1. Do the residents have standing?
Defendant argues that the Association has no standing to sue and that, therefore, the action should be dismissed. The trial court disagreed and defendant claims it erred in so doing. Two standing questions are before us. The first pertains to the right of a private person, as distinguished from a public official, to bring a suit to enjoin the maintenance of a public nuisance. The original rule at common law was that a citizen had no standing to sue for abatement or suppression of a public nuisance since
such inconvenient or troublesome offences [sic], as annoy the whole community in general, and not merely some particular persons; and therefore are indictable only, and not actionable; as it would be unreasonable to multiply suits, by giving every man a separate right of action, by what damnifies him in common only with the rest of his fellow subjects.
IV BLACKSTONE COMMENTARIES 167 (1966). It was later held that a private individual might have a tort action to recover personal damages arising from the invasion of the public right. Y.B. 27 Hen. VIII, Mich, pi. 10, cited in RESTATEMENT, supra, § 821C comment a. However, the individual bringing the action was required to show that his damage was different in kind or quality from that suffered by the public in common. PROSSER, supra, § 90, at 646; HARPER & JAMES, THE LAW OF TORTS § 1.23, at 64-5 (1956).
The rationale behind this limitation was two-fold. First, it was meant to relieve defendants and the courts of the multiple actions that might follow if every member of the public were allowed to sue for a common wrong. Second, it was believed that a harm which affected all members of the public equally should be handled by public officials. RESTATEMENT,
supra,
§ 821C comment a.
See also Engle v. Clark,
We hold, therefore, that because the acts allegedly committed by the patrons of the neighborhood center affected the residents’ use and enjoyment of their real property, a damage special in nature and different in kind from that experienced by the residents of the city in general, the residents of the neighborhood could bring an action to recover damages for or enjoin the maintenance of a public nuisance.
2. May the Association bring the action on behalf of its members?
We have not previously decided whether an association or other organization has standing to assert the claims of its members in a representational capacity. The federal courts, confined by the “case or
*6
controversy” requirements of article III, § 2, cl. 1 of the United States Constitution, have enunciated a three part test. The United States Supreme Court has held that an association has standing to sue on behalf of its members when (a) its members would have standing to sue in their own right; (b) the interests which the association seeks to protect are relevant to the organization’s purpose; and (c) neither the claim asserted nor the relief requested requires the participation of individual members.
Warth v. Seldin,
We have previously determined that the question of standing in Arizona is not a constitutional mandate since we have no counterpart to the “case or controversy” requirement of the federal constitution.
State v. B Bar Enterprises,
DEFENDANT’S DERIVATIVE RESPONSIBILITY
Defendant claims that its business should not be held responsible for acts com *7 mitted by its patrons off the premises of the Center. It argues that since it has no control over the patrons when they are not on the Center’s premises, it cannot be enjoined because of their acts. We do not believe this position is supported either by precedent or theory.
In
Shamhart v. Morrison Cafeteria Co.,
Under general tort law, liability for nuisance may be imposed upon one who sets in motion the forces which eventually cause the tortious act; liability will arise for a public nuisance when “one person’s acts set in motion a force or chain of events resulting in the invasion.” RESTATEMENT, supra, § 824 comment b. We hold, therefore, that defendant’s activity may be enjoined upon the showing of a causal connection between that activity and harm to another.
The testimony at the hearing establishes that it was the Center’s act of offering free meals which “set in motion” the forces resulting in the injuries to the Armory Park residents. Several residents testified that they saw many of the same transients passing through the neighborhood and going in and out of the Center. We find the testimony sufficient to support the trial judge’s finding of a causal link between the acts of ECS and the injuries suffered by the Armory Park residents. The court of appeals thus erred by holding that there was no evidence from which the trial court could have concluded that ECS had engaged in conduct which would render it causally responsible for the interferences. The question is not whether defendant directly caused each improper act, but whether defendant’s business operation frequently attracted patrons whose conduct violated the rights of residents to peacefully use and enjoy their property.
REASONABLENESS OF THE INTERFERENCES
Since the rules of a civilized society require us to tolerate our neighbors, the law requires our neighbors to keep their activities within the limits of what is tolerable by a reasonable person. However, what is reasonably tolerable must be tolerated; not all interferences with public rights are public nuisances. As Dean Prosser explains, “[t]he law does not concern itself with trifles, or seek to remedy all of the petty annoyances and disturbances of everyday life in a civilized community even from conduct committed with knowledge that annoyance and inconvenience will result.” PROSSER, supra, § 88, at 626. Thus, to constitute a nuisance, the complained-of interference must be substantial, intentional and unreasonable under the circumstances. RESTATEMENT, supra, § 826 comment c and § 821F. Our courts have generally used a balancing test in deciding the reasonableness of an interference. See McQuade v. Tucson Tiller *8 Apartments, supra. The trial court should look at the utility and reasonableness of the conduct and balance these factors against the extent of harm inflicted and the nature of the affected neighborhood. We noted in the early case of MacDonald v. Perry:
What might amount to a serious nuisance in one locality by- reason of the density of the population, or character of the neighborhood affected, may in another place and under different surroundings be deemed proper and unobjectionable. What amount of annoyance or inconvenience caused by others in the lawful use of their property will constitute a nuisance depends upon varying circumstances and cannot be precisely defined.
The trial judge did not ignore the balancing test and was well aware of the social utility of defendant’s operation. His words are illuminating:
It is distressing to this Court that an activity such as defendants [sic] should be restrained. Providing for the poor and the homeless is certainly a worthwhile, praisworthy [sic] activity. It is particularly distressing to this Court because it [defendant] has no control over those who are attracted to the kitchen while they are either coming or leaving the premises. However, the right to the comfortable enjoyment of one’s property is something that another’s activities should not affect, the harm being suffered by the Armory Park Neighborhood and the residents therein is irreparable and substantial, for which they have no adequate legal remedy.
Minute Entry, 6/8/84, at 8. We believe that a determination made by weighing and balancing conflicting interests or principles is truly one which lies within the discretion of the trial judge.
State v. Chappie,
The common law has long recognized that the usefulness of a particular activity may outweigh the inconveniences, discomforts and changes it causes some persons to suffer. We, too, acknowledge the social value of the Center. Its charitable purpose, that of feeding the hungry, is entitled to greater deference than pursuits of lesser intrinsic value. It appears from the record that ECS purposes in operating the Center were entirely admirable. However, even admirable ventures may cause unreasonable interferences.
See e.g., Assembly of God Church of Tahoka v. Bradley,
ZONING
ECS argues that its compliance with City of Tucson zoning regulations is a conclusive determination of reasonableness. We agree that compliance with zoning provisions has some bearing in nuisance eases. We would hesitate to find a public nuisance, if, for example, the legislature enacted comprehensive and specific laws concerning the manner in which a particular activity was to be carried out.
Accord
RESTATEMENT,
supra,
§ 821B comment f. We decline, however, to find that ECS’ compliance with the applicable zoning provisions precludes a court from enjoining its activities. The equitable power of the judiciary exists independent of statute. Although zoning and criminal provisions are binding with respect to the type of activity, they do not limit the power of a court acting in equity to enjoin an unreasonable, albeit permitted, activity as a public nuisance.
Accord State ex rel. Carlson v. Hatfield,
The determination of the type of business to be permitted in a particular neighborhood, therefore, may be left to administrative agencies or legislative bodies. However, the judgment concerning the manner in which that business is carried out is within the province of the judiciary. RESTATEMENT, supra, § 821B comment f. See also J. JOYCE, TREATISE ON THE LAW GOVERNING NUISANCES § 73, at 115 (1906). Zoning provisions may permit one’s neighbor to operate a business. This does not give him license to use one’s yard, nor permit his customers to do so.
In so far as
Desruisseau v. Isley,
CRIMINAL VIOLATION
Occasionally we have indicated that conduct which violates a specific criminal statute is an element of public nuisance for civil tort claims.
See, e.g., State v. B Bar Enterprises, Inc., supra; Spur Industries, supra; State ex rel. Sullivan v. Phoenix Savings Bank & Trust Co.,
In MacDonald v. Perry, supra, we indicated that the inquiry in a nuisance claim is not whether the activity allegedly constituting the nuisance is lawful but whether it is reasonable under the circumstances. The Restatement states that a criminal violation is only one factor among others to be used in determining reasonableness. That section reads:
(1) A public nuisance is an unreasonable interference with a right common to the general public.
(2) Circumstances that may sustain a holding that an interference with a public right is unreasonable include the following:
(a) Whether the conduct involves a significant interference with the public health, the public safety, the public peace, the public comfort or the public convenience, or
(b) whether the conduct is proscribed by a statute, ordinance or administrative regulation, or
(c) whether the conduct is of a continuing nature or has produced a permanent or long-lasting effect, and, as the actor knows or has reason to know, has a significant effect upon the public right. (Emphasis supplied.)
RESTATEMENT, supra, § 821B. Comment d to that section explains:
It has been stated with some frequency that a public nuisance is always a criminal offense. This statement is susceptible of two interpretations. The first is that in order to be treated as a public nuisance, conduct must have been already proscribed by the state as criminal. This is too restrictive____ [Tjhere is clear recognition that a defendant need not be subject to criminal responsibility.
*10 RESTATEMENT, supra, § 821B comment d, at 89.
Our earlier decisions indicate that a business which is lawful may nevertheless be a public nuisance. For example, in
Spur Industries, supra,
we enjoined the defendant’s lawful business. We explained that “Spur is required to move not because of any wrongdoing on the part of Spur, but because of a proper and legitimate regard of the courts for the rights and interests of the public.”
We hold, therefore, that conduct which unreasonably and significantly interferes with the public health, safety, peace, comfort or convenience is a public nuisance within the concept of tort law, even if that conduct is not specifically prohibited by the criminal law.
COSTS
Pursuant to Rule 21(d), the court of appeals awarded costs in the amount of $1,003.50 to ECS. Given the charitable nature of ECS’ activities and the unique questions presented in this dispute, we feel it is inappropriate to payment of litigation costs of ECS. Consequently, we order each side to bear its own costs of appeal.
CONCLUSION
The trial court’s order granting the preliminary injunction is affirmed. By affirming the trial court’s preliminary orders, we do not require that he close the center permanently. It is of course, within the equitable discretion of the trial court to fashion a less severe remedy, if possible. The opinion of the court of appeals is vacated. The case is remanded for further proceedings.
Notes
. The ultimate findings of the trial court (see Rule 65(c), Ariz.R.Civ.P., 16 A.R.S.) are found in its minute entry dated June 8, 1984.
. In Arizona relief by "special action" has replaced the relief previously granted by prerogative writs such as certiorari, mandamus or prohibition. See Rule 1, Ariz.R.Sp.Act., 17A A.R.S.
. This statute was neither raised nor argued by the plaintiff; in fact, the plaintiff expressly denied any statutory violation by the defendant.
. Considerable controversy exists with respect to whether a litigant has standing to sue in federal court absent a showing of a personal, particularized injury. These cases involve, for the most part, litigation over the government’s alleged violation of constitutional or statutory rights possessed by the public in general.
