The opinion of the Court was delivered by POLLOCK, J.
This case questions the validity of an ordinance that provides for appointment of detectives by the police chief with the approval of the governing body. In reported decisions, both the Law Division, 199 N.J. Super. 549 (1984), and the Appellate Division, 199 N.J. Super. 554 (1985), found the ordinance to be valid. We granted certification, 101 N.J. 291 (1985), and now affirm the judgment of the Appellate Division.
*221 Before 1981, N.J.S.A. 40A:14-118 gave municipal governing bodies broad authority to regulate the internal affairs of police departments, including the authority to prescribe the duties and functions of police officers. The powers of a chief of police derived not from a statute, but from municipal ordinances and regulations. Smith v. Township of Hazlet, 63 N.J. 523, 526-27 (1973). During this period, a Little Falls ordinance had empowered the Township Committee to appoint members of the police department, to prescribe duties of the members, and had established a detective bureau, to which members were assigned by the chief of police with the approval of the police commissioner.
In 1981 the Legislature amended N.J.S.A. 40A:14-118 to redefine the relationship between a municipal governing body and the chief of police. The amendment states that municipalities by ordinance shall "provide for a line of authority relating to the police function * * *."[1] The statute further states that the ordinance may provide
for the appointment of a chief of police and such and; as members, officers and personnel as shall be deemed necessary, the determination of their terms of *222 office, the fixing of their compensation and the prescription of their powers, functions and duties, all as the governing body shall deem necessary for the effective government of the force.
Furthermore, the statute declares that if the governing body establishes the position of chief of police, the chief "shall be the head of the police force and that he shall be directly responsible to the appropriate authority for the efficiency and routine day to day operations" of the police force. Pursuant to policies established by the appropriate authority, the chief shall "[p]rescribe the duties and assignments of all subordinates and other personnel." N.J.S.A. 40A:14-118c. By granting chiefs of police express statutory authority, the statute sought to avoid undue interference by a governing body into the operation of the police force.
In 1983, the Little Falls Township Committee adopted Ordinance 500, which established a detective bureau and provided that the police chief should appoint detectives with the approval of the Township Committee.[2] A dispute arose between the Township Committee, Mayor and Police Commissioner, on the *223 one hand, and, on the other, the Chief of Police about who had the authority to designate detectives. After the police commissioner and Township Committee twice disapproved the chief's choice of detectives, the Passaic County Prosecutor filed this action seeking a declaratory judgment that Ordinance 500 was invalid. Subsequently, the Chief of Police joined the action as a plaintiff.
The parties filed cross-motions for summary judgment. Noting that detectives must possess greater skill and experience *224 than patrol officers, the Law Division ruled that the permanent appointment of a detective is within the authority of the governing body. 199 N.J. Super. at 553-54. The Appellate Division affirmed substantially for the reasons set forth in the opinion of the Law Division. 199 N.J. Super. at 558.
The parties are in accord that under the statute the governing body has the power to appoint and promote members of the police force, and that the police chief has the power to assign members and conduct the day-to-day operations of the force. They disagree, however, whether the designation of a detective is included in the municipality's power to promote and appoint or in the chief's power to make assignments. Thus, the question becomes whether the designation of a detective should be considered to be an appointment or a promotion by the governing body or an assignment by the chief. In answering the question, we look to the difference in status, compensation, and duties of a patrol officer and of a detective.
Patrol officers, who often walk a beat or ride in a patrol car, are engaged primarily in preventing crime and protecting public safety. Detectives are entrusted with the more sensitive responsibility of detecting and investigating criminal activity. Unlike uniformed officers, detectives often work in plain clothes and may receive higher pay than patrol officers. See City Council of Garfield v. Perrapato, 117 N.J. Super. 184, 194 (App.Div. 1971). From this, we conclude that the designation of a detective is more like an appointment or a promotion than an assignment of a subordinate within the police force.
By separate ordinance, Little Falls detectives receive a $250 annual stipend over a patrol officer's salary. Moreover, the Little Falls ordinance makes the appointment of detectives permanent, and not subject to changes at the discretion of the chief that typify assignments. Significantly, the ordinance *225 provides that "[d]etectives shall be appointed by the Chief of Police with the approval of the Township Committee." Rather than constituting undue interference by the governing body in the operation of the police force, the ordinance represents the sharing of the power of appointment by the governing body with the police chief.
The Prosecutor and Chief of Police contend that the decision of the Appellate Division in this matter conflicts with Gauntt v. City of Bridgeton, 194 N.J. Super. 468 (App.Div. 1984). In Gauntt, the director of the Department of Police & Fire, among other things, assigned policemen to perform certain tasks, ordered the police chief to consult with him before making any training assignments, suggested to the chief that he should assign policemen to patrol particular areas, and overruled the police chief's choice for supervisor of the detective division. Id. at 474-78. As a result, the police chief brought an action claiming that the director had usurped the chief's authority. In resolving that issue, the Appellate Division determined that the function of the governing body was to formulate "fundamental principles to serve as broad guides to the chief of police in making his decisions with respect to discharging his responsibility for the efficiency and routine day to day operation of the police department." Id. at 486. Using that approach, the Appellate Division found that the director's suggestion that officers patrol particular areas was an appropriate policy statement. In other instances, including the appointment of the head of the detective division, the Appellate Division found that the director had infringed on the chief's "authority to prescribe the assignments of all subordinates within his department." Id. at 488. Consistent with the earlier portion of this opinion, we believe that the designation of the head of a detective division should be viewed not as an assignment, but as an appointment or promotion. To the extent that Gauntt implies that the chief's power to assign includes the power to designate the head of the detective division, we reject it.
*226 In its decision in the present case, the Appellate Division noted that this action was originally instituted by the Passaic County Prosecutor and that the Little Falls Chief of Police was subsequently added as a plaintiff, apparently because of some doubt about the Prosecutor's standing to bring the action. 199 N.J. Super. at 556 n. 1. Although it recognized that the joinder of the Chief rendered the issue moot, the Appellate Division cast doubt on the Prosecutor's standing to bring this action. Id. We believe we must dispel that doubt. See In re Boardwalk Regency Corp., 90 N.J. 361, 367-68 (technically moot issue may be judicially reviewed when matter is of public interest), appeal dismissed, 459 U.S. 1081, 103 S.Ct. 562, 74 L.Ed.2d 927 (1982).
When plaintiffs present a question of substantial public interest, any slight additional private interest will suffice to afford standing. See New Jersey State Chamber of Commerce v. New Jersey Election Law Enforcement Comm'n, 82 N.J. 57, 68 (1980) (lobbyists have standing to challenge campaign finance reporting law, even though law's effect on them would be inconsequential); Salorio v. Glaser, 82 N.J. 482, 490-93, cert. denied and appeal dismissed, 449 U.S. 874, 804, 101 S.Ct. 215, 49, 66 L.Ed.2d 94, 7 (1980) (New York residents have standing to challenge New Jersey transportation tax, even though tax will not increase plaintiff's total tax liability). Here, there is a substantial public interest in resolving the issue of who has authority to name police officers to a detective bureau. The proper allocation of responsibilities between a governing body and the chief of police is too important to be left in limbo. As the chief law enforcement officer in the county, the prosecutor has a legitimate interest in the relationship between a governing body and the chief of police on so significant a question. See N.J.S.A. 2A:158-5 (county prosecutor shall "use all reasonable and lawful diligence for the detection, arrest, indictment, and conviction of offenders against the laws"); Dep't of Law & Public Safety, Division of Criminal Justice, County Prosecutors' Ass'n, New Jersey Prosecutor's Manual 7-1 (1984). Consequently, the Passaic County Prosecutor has *227 standing, even in the absence of the Little Falls Chief of Police as a party, to bring the present action.
The judgment of the Appellate Division is affirmed.
For affirmance  Chief Justice WILENTZ and Justices CLIFFORD, HANDLER, POLLOCK, O'HERN, GARIBALDI, and STEIN  7.
For reversal  None.
