In his petition for writ of mandate against defendants and respondents city of San Diego, members and directors of its civil service commission and Chief of Police A. E. Jansen, plaintiff and appellant alleges generally that for 14 years he was a police officer in the city of San Diego under classified civil service; that on September 9, 1956, a quantity of marijuana was found in plaintiff’s possession and on said date he was suspended from his position and placed in jail; that thereafter on September 12, 1956, he received a copy of a letter sent by said defendant chief of police to the civil service commission informing the commission that plaintiff had been discharged from the department as of September 10, 1956, because when he was arrested by *777 officers of the department there was found a quantity of marijuana in his possession; that plaintiff would be charged with such offense and prosecuted in the state courts and that plaintiff was given the opportunity to resign from the department but declined to do so.

It is then alleged that plaintiff demanded a hearing within five days, as required by section 23.1204, San Diego Municipal Code, but due to certain representations made by the personnel director he did not assert his rights at that time; that he was brought to trial in the superior court on a criminal charge of illegal possession of marijuana; that a mistrial resulted at the first trial of the case; that the jury disagreed at a second trial and that he was acquitted on a third trial; that he sought a hearing for reinstatement before the civil service commission and it refused such hearing because a proper and timely demand had not been made within the prescribed period; that, as a result of mandamus proceedings in the superior court, the commission ivas ordered to hold such hearing and that such hearing be limited to the charges contained in the letter from the chief of police to the civil service commission. Pursuant to this writ, a hearing was had and the civil service commission entered its findings of fact and decision that plaintiff was in unlawful and improper possession of marijuana on the date alleged and concluded that plaintiff had been guilty of conduct unbecoming an officer or employee of the city. It affirmed the actions of the chief of police in discharging plaintiff.

Plaintiff claimed before the trial court on the hearing of this writ of mandate to restore plaintiff to his former position, with back pay, that he was not afforded a full and fair hearing before said commission; that it had exceeded its jurisdiction; that the hearing was not held as prescribed by law; and that the commission had acted arbitrarily and abused its discretion. It is here argued that the evidence produced at said hearing before the commission was insufficient and obtained by illegal search and seizure and that plaintiff was prejudiced in his defense by refusal of the police department and the commission to reveal the identity of a claimed “informer.” (Citing such authority as Roviaro v. United States, 353 U.S. 53 [ 77 S.Ct. 623 , 1 L.Ed.2d 639 ]; Portomene v. United States, 221 F.2d 582 ; Sorrentino v. United States, 163 F.2d 627 ; United States v. Conforti, 200 F.2d 365 , and People v. McShann, 50 Cal.2d 802 [ 330 P.2d 33 ].)

It is also argued by plaintiff that the commission went *778 beyond the scope of the nature of the charge set forth in the letter from the chief of police to the commission and that the commission disregarded the verdict of the jury in determining the question of possession of marijuana by plaintiff.

Defendants, by way of answer, deny generally these allegations and allege that plaintiff was guilty of laches in bringing this action; that the civil service commission held a full and fair hearing and plaintiff was present and represented by counsel. A transcript of all the proceedings had before said commission has been furnished for examination by this court. These were the general issues presented in a joint pretrial statement:

Plaintiff’s story before the commission was that this woman (apparently the so-called informer) who sat in his ear with him “planted” the marijuana there to “frame” him; that the marijuana found in his home was lawfully procured by him because he had worked with other officers on the narcotics detail and that the marijuana found in his clothes when he was searched was placed there as a sample to take home overnight while investigating a ease. There was testimony that the chief of police, in April 1953, warned plaintiff of his association with suspicious narcotic addicts since such association might eventually lead to trouble. There is no claim that the purported “informer” had anything to do with his possession of marijuana in his home or on his person. These facts, standing alone, may well have justified the finding of the commission and the trial court.

The trial judge, in a memorandum opinion, recited that petitioner Barr did not contend that the evidence adduced before the civil service commission did not support its decision, and, after reading the record (475 pages) he found the evidence was sufficient. He agreed that the arresting officer should have disclosed the name of the alleged informer, but believed it not prejudicial because the record showed that petitioner knew the name of the informant and he had caused the issuance of 12 subpoenas for her attendance at the three separate trials of petitioner and her name was mentioned many times in the transcript, and it appears that she was, at different times, in Los Angeles, Long Beach, Texas and Las Vegas, Nevada; that it was possible that the witness could not have been produced before the commission, otherwise plaintiff would have called her. He also recites extracts from the record of the hearing affirming the statement of the trial court. The examination of plaintiff by his own counsel there was as follows;

In the course of the argument made by plaintiff’s counsel at the close of the evidence before the commission, he stated, “And I would say this, that we stated who we believe was the confidential informant; we said it was this woman. Now, her *780 identity, at least as far as we are concerned, has been disclosed, so from that standpoint it is no longer a secret. Secondly, we have evidence, and you have before you evidence, to the effect that we tried to subpoena her for the three criminal trials and that she was not available and could not be served anywhere in California; and our information is that she was and has been since September of 1956 a resident of Nevada.” The trial judge then stated in his memorandum opinion that “In addition to the marijuana found in petitioner’s car, marijuana was found in his home; and it is not shown that this marijuana was found in consequence of any information obtained from any informant. The point that prejudice resulted from the ruling seems to be an afterthought.”

Specific findings then followed that plaintiff had a full and fair hearing before the commission in accordance with the law and the writ of mandate previously issued; that the commission acted within its proper jurisdiction and did not act arbitrarily and that plaintiff was not prejudiced by the ruling of the commission in reference to the disclosure of the name of the claimed informant because he was, at all times, aware of her identity; that none of the allegations of plaintiff’s petition were true and the reason for plaintiff’s discharge from the police force was supported by the evidence and justified. Judgment went accordingly and the writ was denied.

Without further recitation of the conflicts appearing therein, an examination of the entire record indicates that the findings and decision made by the civil service commission were supported by substantial evidence as found by the trial court (Pores v. Purity Milk Co., 135 Cal.App.2d 305 [ 287 P.2d 169 ] ; Code Civ. Proc., § 1094.5, subds. (b) and (c)); that plaintiff was not denied a full and fair hearing; that statutory rules of procedure were substantially followed; that the commission did not exceed its jurisdiction; that no prejudice was suffered by plaintiff by refusal to give the name of the informant, where plaintiff was shown to have such knowledge and endeavored to subpoena her at the time of the several trials. (DeLosa v. Superior Court, 166 Cal.App.2d 1 [ 332 P.2d 390 ]; People v. McShann, 50 Cal.2d 802 , supra; People v. Lazzara, 131 Cal.App.2d 663 [ 281 P.2d 4 ].) The reason or cause for removal was sufficiently stated in the notice. Sections 23.1203 and 23.1204, San Diego Municipal Code, include as one of the grounds for removal “Conduct unbecoming an officer.” Rule 11, section 4 of the civil service rules, *781 provides that the commission need not be bound by the common law or statutory rules of evidence and procedure. Since the civil service commission is an administrative body, such a provision relating to the manner in which it will conduct its hearings is usual. (California Administrative Code relative to the Public Utilities Commission hearings, title 20, article 16, section 55.)

The fact that plaintiff was acquitted of a charge of possession of marijuana on the day alleged is not determinative of the issue here presented. This same question arose in Skaggs v. Horrall, 83 Cal.App.2d 424 [ 188 P.2d 774 ], quoting from Kavanaugh v. Paull, 55 R.I. 41 [ 177 A. 352 ], where it was said:

Judgment affirmed.
