Opinion
In this case we must determine the propriety of a discovery order which requires local legislators to disclose portions of discussions in which they participated prior to the enactment of a municipal employee salary ordinance. The real party in interest, plaintiff in the underlying taxpayer suit, seeks such disclosure to aid in establishing her contention that the board of supervisors adopted the salary ordinance as a result of a threatened illegal strike by public employees. The taxpayer suit challenges the validity of the salary ordinance on the basis of its alleged connection with the threatened strike; the trial court, over the objections of the county and the individual legislators, ordered the officials “to answer questions as to discussions of strikes or threats of strikes at executive sessions of the Board of Supervisors.” Petitioners now seek a writ of prohibition to restrain the trial court from enforcing its order.
As we explain, we have concluded that the discovery order violates a longstanding legal principle precluding judicial inquiry into the motivation or mental processes of legislators in enacting legislation. Although the taxpayer suggests that there is an exception to this principle when the motivation of the lawmakers is relevant to the validity of legislation, as it is claimed to be in the underlying complaint, we shall explain that even in such exceptional circumstances the authorities have prohibited any direct inquiries into the subjective reasoning of individual legislators. Accordingly, we have determined that the requested writ of prohibition should issue.
Real party in interest Carole Burroughs instituted the underlying *724 taxpayer suit seeking to enjoin the implementation of Ordinance No. 10,922 of the County of Los Angeles, an ordinance which establishes the 1974-1975 fiscal year salaries and wages for a majority of county employees. The complaint alleges that the Los Angeles County Board of Supervisors “under duress and coercion and as a direct result of . . . threatened illegal strike activities” by a variety of municipal employee organizations entered into an agreement with the employee organizations in which the supervisors agreed to enact a salary ordinance providing specified benefits in return for the employees’ promise not to strike. The complaint further alleges that thereafter the supervisors enacted the challenged salary ordinance “as a direct result” and “under [the] duress and coercion” of the threatened illegal strike. Claiming that these circumstances render the ordinance void, the complaint seeks a declaration of invalidity and an injunction restraining the city from implementing the challenged legislation.
In preparing for the hearing on the preliminary injunction, the taxpayer deposed the five members of the board of supervisors who had voted on the ordinance, the director and deputy director of the county personnel department and the executive officer-clerk of the board of supervisors. The taxpayer attempted to question each deponent about discussions which had taken place between the supervisors and the county’s labor negotiators at several executive sessions of the board preceding negotiations between the county and its employees’ representatives. The taxpayer concedes that the purpose of such questioning was to probe the reasons behind the supervisors’ subsequent adoption of the salary ordinance and to uncover evidence that would demonstrate that the strike threat was a substantial factor in producing the ultimate legislative wage increases.
The deponents, upon advice of counsel, refused to answer any questions relating to the executive session discussions on the ground that such information was privileged. 1 The taxpayer then moved for an order compelling the deponents to answer all questions concerning such executive session discussions. After a hearing, the trial court granted the motion in part, ordering the deponents to reveal the contents of such *725 discussions insofar as they involved strikes or threats of strikes. 2 Petitioners seek a writ restraining the enforcement of this order.
Both parties in this proceeding appear to assume that the propriety of the trial judge’s discovery order rests solely upon the application of section 1040 of the Evidence Code,
3
which establishes a conditional privilege for “official information.” (See
Pitchess
v.
Superior Court
(1974)
In our view, however, we need not resolve these conflicting claims as to the proper application of section 1040, for we believe that the discovery order in the instant case implicates a more fundamental, historically enshrined legal principle that precludes any judicially authorized inquiry into the subjective motives or mental processes of legislators. As early as 1855, Chief Justice Murray declared in an opinion for this court: “I know of no authority this Court possesses to inquire into the motives of the Legislature in the passage of any law; on the contrary, it has been uniformly held, that they could not be inquired into.”
(People
v.
Bigler
(1855)
As Justice Field wrote for the United States Supreme Court in
Soon Hing v. Crowley
(1885)
Moreover, the authorities, both in California and more generally, make clear that the rule barring judicial probing of lawmakers’ motivations applies to local legislators as well as to members of the state Legislature or of Congress. (See, e.g.,
Nickerson
v.
San Bernardino
(1918)
On one level, the doctrine which precludes judicial delving into the subjective mental processes of individual legislators is a corollary of the related legal principle which establishes that the validity of a legislative act does not depend on the subjective motivation of its draftsmen but rests instead on the objective effect of the legislative terms. Thus, on many occasions this court has declared: “ ‘. . . [A] judiciary must judge by results, not by the varied factors which may have determined legislators’ votes ....’”
(Wilke & Holzheiser, Inc.
v.
Dept. of Alcoholic Bev. Control
(1966)
Although the taxpayer concedes that normally courts will not invalidate legislation on the basis of illicit motives or coercive influences which may have actuated the legislators, she asserts that there is an exception to this general rule when legislation is passed under the coercive threat of an illegal strike. In support of this theory, the taxpayer relies on the recent Court of Appeal opinion in
Grasko
v.
Los Angeles City Board of Education
(1973)
In the first place, we entertain grave doubts both as to whether the
Grasko
case supports the taxpayer’s theory, and, more fundamentally, whether the
Grasko
holding is correct even on its own limited terms. Unlike the instant case, the
Grasko
decision did not involve an attack on the validity of a legislative
act,
and thus the
Grasko
court had no occasion to consider the effect of the general principle precluding the invalidation of legislation on the basis of improper motivation. Moreover, in concluding that the illegality of a strike necessarily taints any contractual agreement entered into by the public employer to settle the strike, the
Grasko
court appears to have vastly oversimplified the complex questions involved in determining what sanctions for illegal strikes may appropriately be implemented by the judiciary in the
*729
absence of definitive legislation.
7
On this point, at least one other Court of Appeal has reached a conclusion contrary to that of the
Grasko
court, and has affirmed the validity of an agreement entered into by a public employer in the course of a strike settlement. (See
East Bay Mun. Employees Union
v.
County of Alameda
(1970)
We need not resolve the merits of the taxpayer’s cause of action at this pretrial discovery stage, however, for even if we assume that the ordinance at issue could be invalidated if it resulted from the threat of an illegal strike, the authorities make clear that the taxpayer still is not entitled to directly question the legislators as to their mental processes or their reasons for enacting the ordinance. In other words, even assuming that the ulterior purpose behind the enactment is relevant to the ordinance’s validity, the taxpayer still may not prove such ulterior purpose by requiring legislators to testify about their reasoning process or by questioning others about the factors which may have led to the legislators’ votes. Even under such circumstances, the principle barring judicially authorized inquiry of legislators’ motivation remains intact.
Stahm
v.
Klein
(1960)
The question before the
Stahm
court was whether, given the relevance of the “bad faith” of the legislators, the employee was entitled to prove such bad faith by questioning the individual legislators about their subjective motivation or by introducing “evidence of oral conversations relating to ill feeling among the members of the official family ... to prove the presence in the minds of the council members of good or bad thoughts . . . .” (
As numerous cases demonstrate, the refusal to permit direct inquiry into the subjective motivations of legislators does not insulate
*731
legislative abolition of civil service positions from effective review. In many instances, litigants have been able to demonstrate by virtue of objective criteria that a particular abolition was undertaken in bad faith in an attempt to circumvent applicable civil service regulations. Thus, in
Rexstrew
v.
City of Huntington Park, supra,
Professor Bickel has captured the essence of the policies underlying the judicial principle which we apply in this case. “It is simply unthinkable,” Professor Bickel has written, “that members of legislative majorities should from time to time be subject to cross-examination in various courts over the country regarding their state of mind when they voted. That is no more representative government than it would be judicial process for judges to be subject to cross-examination by legislative committees about their state of mind in deciding cases. It *732 seems almost anticlimactic to add that legislatures whose members were subject to call for testimony in this fashion would be hard put to find the time to legislate.” (Bickel, The Least Dangerous Branch (1962) p. 215.)
The potential passages and pathways of legislative motivation are as complex as those of the labyrinth of King Minos of Crete. We conclude that the trial court erred in ordering the deponents to answer questions as to conversations relating to the legislators’ reasons for voting for the challenged ordinance.
Let a peremptory writ of prohibition issue, restraining respondent from enforcing the challenged order.
Wright, C. J., McComb, J., Mosk, J., Sullivan, J., Clark, J., and Richardson, J., concurred.
Notes
Although the record before us does not contain transcripts of the depositions, it appears that the five supervisors were also directly asked whether they would have voted for the salary ordinance in the absence of a strike threat; all the supervisors apparently answered this question, three indicating that they would have voted for the ordinance in any event and two stating that their vote was influenced by the strike threat. As we explain hereafter, we believe that this entire line of questioning was improper and should not have been pursued at the deposition.
The challenged order reads in relevant part: “Motion granted in part as follows: [Deponents] are ordered to resume their depositions at times and places agreed to by counsel. . . and then and there to answer questions as to discussions of strikes or threats of strikes at executive sessions of the Board of Supervisors. To such extent, Court finds interest of justice outweighs necessity of preserving confidentiality. Balance of motion denied.”
Section 1040 provides: “(a) As used in this section, ‘official information’ means information acquired in confidence by a public employee in the course of his duty and not open, or officially disclosed, to the public prior to the time the claim of privilege is made.
“(b) A public entity has a privilege to refuse to disclose official information, and to prevent another from disclosing such information, if the privilege is claimed by a person authorized by the public entity to do so and:
“(1) Disclosure is forbidden by an act of Congress of the United States or a statute of this state; or
“(2) Disclosure of the information is against the public interest because there is a necessity for preserving the confidentiality of the information that outweighs the necessity for disclosure in the interest of justice; but no privilege may be claimed under this paragraph if any person authorized to do so has consented that the information be disclosed in the proceeding. In determining whether disclosure of the information is against the public interest, the interest of the public entity as a party in the outcome of the proceeding may not be considered.”
Section 54957.6 provides: “Notwithstanding any other provision of law, a legislative body of a local agency may hold executive sessions with its designated representatives prior to and during consultations and discussions with representatives of employee organizations regarding the salaries, salary schedules, or compensation paid in the form of fringe benefits of employees in order to review its position and instruct its designated representatives.”
Because the principle precluding judicial inquiry into legislative motivation is, in part, a reflection of the separation of powers doctrine, the real party in interest seizes upon certain language in our recent case of
