This is an appeal from the action of the superior court in granting an injunction, the effect of which would prohibit the Seattle Police Department from seeking to elicit, under threat of dismissal, answers from individual police officers, either through direct questioning or through polygraph examination, to questions relating to the performance of their official duties.
*308The respondent, Seattle Police Officers’ Guild, a professional association for police officers, as plaintiff, brings this action on behalf of its membership. The appellants (defendants) are the City of Seattle and the Chief of Police, under whose auspices an internal investigation into the conduct of certain police officers was being conducted.
We summarize the agreed facts. During 1970 several Seattle police officers were implicated in a pay-off system. The matter was widely publicized. Public confidence in the integrity of the police department was shaken. The then Acting Chief of Police, Charles R. Gain, initiated a departmental administrative investigation. During the course of the inquiry, the Acting Chief of Police proposed to require those officers interrogated to answer questions put to them relating to their official conduct and in some instances to submit to a polygraph examination all under threat of dismissal if they refused to cooperate.1 By way of affidavit, the Acting Chief of Police asserted that “questions to be asked of the officers will be specifically, directly and narrowly related to the past performance of their official duties” and “at no time during the said investigation or any investigation concerning misconduct will any officer be directed to waive immunity from self-incrimination and prior to directing any officer to answer questions or to submit to a polygraph test, he will be advised that information gained by reason of his answers cannot be used against him in a criminal proceeding.”
Contending that the proposed course of inquiry would contravene the constitutional privilege and protection against self-incrimination found in the fifth amendment to the United States Constitution, respondent instituted this action seeking a writ of prohibition. Appellants answered respondent’s complaint and a hearing was held resulting in the issuance of a temporary injunction, the essence of which was to restrain appellants from disciplining any *309officer who, when questioned, claimed his constitutional privileges or who refused to submit .to a polygraph test.
On appeal the Court of Appeals certified the cause to this court. We accepted jurisdiction.
Basically, two questions are presented which relate to and must be considered in the context of a police department internal administrative investigation of or inquiry into alleged police misconduct. One, may a police officer interrogated in the course of such an inquiry be lawfully disciplined or discharged for claiming his Fifth Amendment privilege against self-incrimination and refusing upon such ground to answer questions pertaining to the performance of his official duties? Two, may a police officer during such an inquiry be validly disciplined for refusing to submit to a polygraph test?
Starting with the premise that Malloy v. Hogan, 378 U.S. 1, 12 L. Ed. 2d 653, 84 S. Ct. 1489 (1964), and subsequent cases impress the privileges of the Fifth Amendment upon state proceedings through the due process clause of the fourteenth amendment to the United States Constitution, we answer the questions presented in the affirmative.
Our answer to the first question requires an examination and interpretation of four relatively recent decisions of the United States Supreme Court.
The first, Garrity v. New Jersey, 385 U.S. 493, 17 L. Ed. 2d 562, 87 S. Ct. 616 (1967), concerned police officers allegedly involved in fixing traffic tickets; During the course of an official investigation and as a prelude to questioning, they were advised that anything they might say could be used against them in a criminal proceeding, that they had the privilege to refuse to answer if their answer would tend to incriminate them, and that if they refused to answer they would be subject to removal from office. They answered the questions. Some of their answers were admitted into evidence, over their objections, in subsequent criminal prosecutions flowing from the investigation. They were convicted. Conceiving the choice imposed upon them, i.e., self-incrimination or job forfeiture, was tantamount to *310coercion, thereby rendering their statements involuntary, the United States Supreme Court, in a five to four decision, reversed their convictions stating, at page 500:
We now hold the protection of the individual under the Fourteenth Amendment against coerced statements prohibits use in subsequent criminal proceedings of statements obtained under threat of removal from office, and that it extends to all, whether they are policemen or other members of our body politic.
The Garrity decision confined its attention and holding to the single proposition that statements obtained in the course of a disciplinary investigation under threat of dismissal from office could not be used as evidence in subsequent criminal prosecutions. As pointed out by the author of the Garrity opinion, Mr. Justice Douglas, in footnote 3 on page 516 of Spevack v. Klein, 385 U.S. 511, 17 L. Ed. 2d 574, 87 S. Ct. 625 (1967), a decision which was delivered on the same day as Garrity, said:
Whether a policeman, who invokes the privilege when his conduct as a police officer is questioned in disciplinary proceedings, may be discharged for refusing to testify is a question we did not reach.
The Garrity decision thus preserved the Fifth Amendment protections for police officers during questioning under threat of dismissal in the course of disciplinary proceedings by precluding use of answers so elicited in subsequent criminal proceedings, thereby, and to that extent, stripping the answers of their incriminating nature. Although the Garrity holding would appear to be an adequate safeguard of the Fifth Amendment privilege against self-incrimination accorded police officers being questioned concerning their official conduct, the respondent contends that the decision in Spevack v. Klein, supra, should also apply to police officers.
In Spevack an order disbarring an attorney was reversed. During disbarment proceedings the attorney involved refused, on the basis of the Fifth Amendment, to produce subpoenaed financial records and to testify before the in*311quiring tribunal. As a result of his refusal he was disbarred. Four members of the court, in an opinion authored by Mr. Justice Douglas, reasoned that the Fifth Amendment extended to lawyers as well as laymen and should not be watered down by imposing the dishonor of disbarment as a penalty for asserting it. Mr. Justice Fortas concurred in the result, but expressed the view that a distinction should be made between an attorney’s right to remain silent sans penalty of disbarment and that of a public employee who is asked questions specifically related to the performance of his official duties. In this respect Justice Fortas stated (385 U.S. 511, at 519):
I would distinguish between a lawyer’s right to remain silent and that of a public employee who is asked questions specifically, directly, and narrowly relating to the performance of his official duties as distinguished from his beliefs or other matters that are not within the scope of the specific duties which he undertook faithfully to perform as part of his employment by the State. This Court has never held, for example, that a policeman may not be discharged for refusal in disciplinary proceedings to testify as to his conduct as a police officer. It is quite a different matter if the State seeks to use the testimony given under this lash in a subsequent criminal proceeding. Garrity v. New Jersey, ante, p. 493. [385 U.S. 493, 17 L. Ed. 2d 562, 87 S. Ct. 616 (1967)]
But a lawyer is not an employee of the State. He does not have the responsibility of an employee to account to the State for his actions because he does not perform them as agent of the State. His responsibility to the State is to obey its laws and the rules of conduct that it has generally laid down as part of its licensing procedures. The special responsibilities that he assumes as licensee of the State and officer of the court do not carry with them a diminution, however limited, of his Fifth Amendment rights. Accordingly, I agree that Spevack could not be disbarred for asserting his privilege against self-incrimination.
This distinction, as urged by Justice Fortas, was formally approved with respect to police officers by a majority of the Supreme Court membership (six with three concurrences) *312in a subsequent decision, Gardner v. Broderick, 392 U.S. 273, 20 L. Ed. 2d 1082, 88 S. Ct. 1913 (1968). In Gardner a police officer was dismissed pursuant to a provision of the New York city charter which required, in pertinent part, that the employment of a city employee would terminate if he should refuse before an appropriate tribunal to answer questions in relation to his official duties on the ground that his answers might tend to incriminate him, or if he should refuse to waive immunity from prosecution on account of any such matter in relation to which he might be properly called upon to testify. The officer was dismissed on the ground that, as a witness before a grand jury investigating alleged bribery and corruption of police officers, he refused to waive immunity from prosecution. This occurred prior to the decision in Garrity v. New Jersey, supra. In holding that the requirement of a waiver of immunity vitiated the dismissal, the Supreme Court, nevertheless, with approval announced the principles which we believe to be applicable in the instant case. It was stated thusly (392 U.S. 273, at 277):
It is argued that although a lawyer [alluding to the Spevack decision] could not constitutionally be confronted with Hobson’s choice between self-incrimination and forfeiting his means of livelihood, the same principle should not protect a policeman. Unlike the lawyer, he is directly, immediately, and entirely responsible to the city or State which is his' employer. He owes his entire loyalty to it. He has no other “client” or principal. He is a trustee of the public interest, bearing the burden of great and total responsibility to his public employer. Unlike the lawyer who is directly responsible to his client, the policeman is either responsible to the State or to no one.
We agree that these factors differentiate the situations. If appellant, a policeman, had refused to answer questions specifically, directly, and narrowly relating to the performance of his official duties, without being required to waive his immunity with respect to the use of his answers or the fruits thereof in a criminal prosecution of himself, Garrity v. New Jersey, supra [385 U.S. 493, 17 L. Ed. 2d 562, 87 S. Ct. 616 (1967)], the privilege against *313self-incrimination would not have been a bar to his dismissal.
(Footnotes omitted.)
The principles announced in Gardner were also applied to employees of the New York City Department of Sanitation in a case decided on the same day, Uniformed Sanitation Men Ass’n v. Commissioner of Sanitation, 392 U.S. 280, 20 L. Ed. 2d 1089, 88 S. Ct. 1917 (1968). As in Gardner, the employees had been discharged because of their refusal to sign waivers of immunity from prosecution in the course of investigatory proceedings concerning alleged corruption in their department. Although reversing a judgment dismissing their claim for relief, the Supreme Court again, as in Gardner, pointed out, at page 284:
As we stated in Gardner v. Broderick, supra [392 U.S. 273, 20 L. Ed. 2d 1082, 88 S. Ct. 1913 (1968)], if New York had demanded that petitioners answer questions specifically, directly, and narrowly relating to the performance of their official duties on pain of dismissal from public employment without requiring relinquishment of the benefits of the constitutional privilege, and if they had refused to do so, this case would be entirely different. In such a case, the employee’s right to immunity as a result of his compelled testimony would not be at stake. But here the precise and plain impact of the proceedings against petitioners as well as of § 1123 of the New York Charter was to present them with a choice between surrendering their constitutional rights or their jobs. Petitioners as public employees are entitled, like all other persons, to the benefit of the Constitution, including the privilege against self-incrimination. Gardner v. Broderick, supra; Garrity v. New Jersey, supra [385 U.S. 493, 17 L. Ed. 2d 562, 87 S. Ct. 616 (1967)]. Cf. Murphy v. Waterfront Commission, 378 U. S. 52, at 79 (1964) [12 L. Ed. 2d 678, 84 S. Ct. 1594]. At the same time, petitioners, being public employees, subject themselves to dismissal if they refuse to account for their performance of their public trust, after proper proceedings, which do not involve an attempt to coerce them to relinquish their constitutional rights.
Mr. Justice Harlan, who had vigorously dissented in *314Garrity and Spevack, joined by Mr. Justice Stewart, concurred in the results of Gardner and Uniformed Sanitation, and speaking of the combination of the four decisions stated (392 U.S. 280, at 285):
I find in these opinions a procedural formula whereby, for example, public officials may now be discharged and lawyers disciplined for refusing to divulge to appropriate authority information pertinent to the faithful performance of their offices. I add only that this is a welcome breakthrough in what Spevack [Spevack v. Klein, 385 U.S. 511, 17 L. Ed. 2d 574, 87 S. Ct. 625 (1967)] and Garrity [Garrity v. New Jersey, 385 U.S. 493, 17 L. Ed. 2d 562, 87 S. Ct. 616 (1967)] might otherwise have been thought to portend.
We are satisfied that Mr. Justice Harlan correctly assessed the thrust and effect of these four decisions. Other courts too have adopted his interpretation. Clifford v. Shoultz, 413 F.2d 868 (9th Cir. 1969); In re Addonizio, 53 N.J. 107, 248 A.2d 531 (1968), Silverio v. Municipal Court, 355 Mass. 623, 247 N.E.2d 379, cert. denied, 396 U.S. 878, 24 L. Ed. 2d 135, 90 S. Ct. 151 (1969); and Kammerer v. Board of Fire & Police Comm’rs, 44 Ill. 2d 500, 256 N.E.2d 12 (1970).
In the Silverio case, supra, the Supreme Judicial Court of Massachusetts, after taking note of Garrity, Spevack, Gardner, and Uniformed Sanitation cases, commented concerning the discharge of a policeman for refusing to answer questions relating to his official conduct, at page 629:
Thus an employee knows that if he fails to divulge information pertinent to the issue of his use or abuse of his public trust he may lose his job. The fact of employment poses the continuing choice of whether to divulge such information. The Constitution of the United States, however, as we understand its construction, does not require that a public employer continue to employ in a position of public trust an employee who declines or renders himself unable to perform the duties of his position on the ground of the constitutional protection against self-incrimination. No threat or pressure of his superior coerces his choice. His choice is his own, even though it may be affected by his expectation that his *315superiors will perform their own public duties in the light of their appraisal of his conduct.
We agree with Mr. Justice Harlan in his concurrence in the Gardner [Gardner v. Broderick, 392 U.S. 273, 20 L. Ed. 2d 1082, 88 S. Ct. 1913 (1968)] and Uniformed Sanitation cases (392 U. S. at 285) [Uniformed Sanitation Men Ass’n v. Commissioner of Sanitation, 392 U.S. 280, 20 L. Ed. 2d 1089, 88 S. Ct. 1917 (1968)] that there is “in these opinions a procedural formula whereby . . . public officials may now be discharged . . . for refusing to divulge to appropriate authority information pertinent to the faithful performance of their offices.
We are in accord with this view.
The only case which would appear to express a contrary view is Luman v. Tanzler, 411 F.2d 164 (5th Cir. 1969) upon which the trial court relied. The issue in Luman, however, was different than in the instant case. Luman, a policeman, had been suspended and was facing simultaneously an administrative disciplinary proceeding and a criminal prosecution. He was seeking to enjoin the disciplinary proceeding pending disposition of the criminal prosecution. The court denied the injunction; however, in passing noted that Luman, if he testified at the disciplinary proceeding, might well prejudice his defense in the criminal action. Under these circumstances, the court felt he should not be penalized for exercising his Fifth Amendment protections. Insofar, otherwise, as the decision might be conceived as being at odds with our view of the sweep of Garrity, Spevack, Gardner, and Uniformed Sanitation it would be representative of a minority approach and one to which we would not now be willing to subscribe.
A police department is a highly sensitive agency entrusted and charged with the duty of protecting the community it serves from the evils of crime and corruption. To efficiently and effectively accomplish its mission it requires the respect and regard of the public, and when it has reason to believe that some of its members may be engaging in disreputable practices, it has a valid interest in purging itself of such practices through internal departmental pro*316cedures and the right to require the full cooperation of its membership to this end.
In the instant case, the questions to be asked the officers involved in the departmental inquiry, by the affidavit of the Acting Chief of Police, were to be specifically, directly, and narrowly related to the past performance of their official duties. The officers were not to be required to waive any immunity they might have, either under Garrity or otherwise, as to the use of their testimony or the fruits thereof in any subsequent prosecution. They were to be advised that information supplied through their answers could not be used against them in later criminal proceedings, and that their refusal to cooperate in the investigation could result in their dismissal. Under these circumstances' we are convinced that within the procedural formula of the Garrity, Spevack, Gardner, and Uniformed Sanitation cases, the Fifth Amendment privilege against self-incrimination would not be a bar to discharge of an officer or officers who refused to answer questions pertaining to the use or abuse of his official duties.
We conclude, therefore, that the trial court was in error when it undertook to enjoin appellants from dismissing or otherwise disciplining any member of the Seattle Police Department for refusing, on the grounds of the Fifth Amendment privilege against self-incrimination, to answer in the course of the departmental inquiry questions specifically, directly, and narrowly related to that member’s performance of his official duties.
We turn now to the second question, that is, whether appellants may require, under penalty of dismissal for refusal, officers questioned during an internal departmental inquiry to submit to a polygraph test. This presents an issue of first impression in this state, and has not been passed upon by the United States Supreme Court. There is a division of authority among the several states which have considered the matter.
The courts of three states, California, Illinois, and Louisiana have upheld dismissals of police who refused during *317the course of administrative investigations into alleged police misconduct to submit to a polygraph test. The courts of two states, Connecticut and Pennsylvania have reached a contrary result.
We think the rationale and the reasoning of the California, Illinois, and Louisiana decisions are the more persuasive, and fully answer the contentions of respondent to the effect that the polygraph test is too fallible and amounts to an invasion of privacy. Furthermore, the Connecticut and Pennsylvania cases are distinguishable from the instant situation.
Roux v. New Orleans Police Dep't, 223 So. 2d 905 (La. App.), aff’d, 254 La. 815, 227 So. 2d 148 (1969), cert. denied, 397 U.S. 1008, 25 L. Ed. 2d 421, 90 S. Ct. 1236 (1970), the most recent of the decisions, involved an internal departmental investigation of a police officer’s involvement with a homicide victim. The officer refused to take a polygraph test and was dismissed. In sustaining the dismissal, the court referred to the cases from the other states, and then predicated its determination upon Fichera v. State Personnel Bd., 217 Cal. App. 2d 613, 32 Cal. Rptr. 159 (1963), stating, at page 911:
We are guided to a great extent in our holding in the present case by what the Court said in the Fichera case [Fichera v. State Personnel Bd., 217 Cal. App. 2d 613, 32 Cal. Rptr. 159 (1963)], and we say also that there may be many circumstances wherein a superior’s order that a subordinate officer submit to a polygraph test would be unreasonable. We quote as follows from that case:
“The polygraph is an extension of the age-old process of assessing the veracity of a witness, by scrutinizing his facial expression, rubescence, tremors, evasion of meeting the eye, and the like. It works through externals and is quite distinct from drug induced revelation, hypnosis, or any other form of narco-analysis. In the limited field of cases such as this one, and those of the prior cases cited above, we find no deprivation of constitutional or legal rights.
“It may be conceded that there'is a considerable degree of fallibility with the polygraph (see Sholnick, Sci*318entific Theory and Scientific Evidence: An Analysis of Lie-Detection, 70 Yale L.J. 694). It is not considered to have enough rehability to justify the admission of expert testimony in the courts based on its results, and a person’s willingness or unwillingness to take the test is without enough probative value to justify its admission. (People v. Carter, 48 Cal.2d 737, 752, 312 P.2d 665.) It was recognized in the Frazee case [Frazee v. Civil Serv. Bd., 170 Cal. App. 2d 333, 338 P.2d 943 (1959)], however, that it does not follow that the tests are completely without value. (170 Cal.App.2d at p. 335, 338 P.2d at pp. 944-945). The test might have proved useful in limiting and channeling the investigation in this case, in which three officers besides appellants were directed to take the tests, and acceded. It might have been an instrument of exculpation and vindication, on the one hand, or of more intensive investigation of the subjects of the test, on the other. We cannot, of course, tell what would have been the ruling of the State Personnel Board, or what our own ruling might have been, had the tests been taken and had produced results considered damaging by appellants’ superiors. We do hold, however, that appellants were not entitled to withhold this means of investigation and at the same time retain their positions as officers of the California State Police.”
While appellant’s refusal to obey the order is not evidence of guilt or of knowledge of the identity of the guilty party, he may not be permitted to refuse to take the polygraph test in view of his sworn duty to cooperate in the investigation of crime. Under all the circumstances in this matter, we find that the order was reasonable.
Reaching a similar result the Appellate Court of Illinois in Coursey v. Board of Fire & Police Comm’rs, 90 Ill. App. 2d 31, 234 N.E.2d 339 (1967), observed, at page 43:
Effective arid efficient operation of a police department requires that allegations of police misconduct be thoroughly investigated. The polygraph machine can be a useful investigative tool when the test is skillfully prepared and is administered and interpreted by a qualified person; while it is not accurate to the degree that absolute judgments can be made as to the veracity of the person tested (People v. Triplett, 37 I112d 234, 226 NE2d 30 (1967)) the results are often reliable within recog*319nized limits. Thus, for example, the results of a polygraph examination may be of help in narrowing the field of persons suspected of an offense or may assist in a determination whether to commence disciplinary action when, as here, there is an accusation against a police officer which he insists is untrue. Be that as it may, the issue is not the accuracy of a polygraph examination, but Coursey’s failure to take an examination.
As we have indicated, the cases relied upon by the trial court and urged upon us by respondent — Molino v. Board of Pub. Safety, 154 Conn. 368, 225 A.2d 805 (1966), and Stape v. Civil Serv. Comm’n, 404 Pa. 354, 172 A.2d 161 (1961) — are distinguishable. In Molino the officers involved, and who were requested to take the polygraph tests, were not accused of criminal or anti-social behavior. Their dereliction which gave rise to the administrative investigation culminating in their refusal to take the polygraph tests was a failure to properly log and report an incident occurring while they were on patrol. Under these circumstances, the court concluded that their refusal together with their failure to properly comply with the police manual did not warrant discharge, noting that the penalty simply did not fit the case. In Stape the court held that a refusal to submit to a polygraph test did not amount to “just cause” for dismissal within the contemplation of the existing civil service regulations. Neither case completely closes the door upon the proposition that in appropriate circumstances a refusal to take a polygraph test could amount to grounds for dismissal.
In the instant case, serious and notorious charges of crime and corruption had, with appreciable cause, been leveled against members of the police department. By the very nature of the charges, serious public doubt was cast upon the integrity, the morality, and the fidelity of the department and its membership. An intensive internal administrative investigation was fully justified. Questioning in the course of the investigation was to be carried on within prescribed constitutional limits.
Under these circumstances, we conclude and hold *320that if, in the exercise, of prudent judgment, the investigating authority determines it reasonably necessary to utilize the polygraph examination as an investigatory tool to test the dependability of prior answers of suspected officers to questions specifically, narrowly, and directly related to the performance of their official duties, then, such investigating authority may properly request such officers to submit to a polygraph test under pain of dismissal for refusal.
Bearing in mind that the reasonableness of an investigating authority’s request, under varying circumstances, can be subjected to judicial scrutiny and abuses of discretion thereby curbed, coupled with the fact that, in any event, the results of a polygraph test and a subject’s willingness or unwillingness to take the test cannot be admitted into evidence in subsequent criminal proceedings, we see no constitutional or legal barrier to the conclusion we have reached.
With the foregoing disposition of the two questions presented we do not reach the remaining contentions of the parties.
Insofar as the temporary injunction issued by the trial court be inconsistent herewith, it is dissolved. Appellants shall recover their costs.
Finley, Hale, Neill, and Stafford, JJ., concur.
Seattle Police Department General Order 70-20 pertains to and requires the cooperation of officers in internal departmental investigations.
