Opinion
SULLIVAN, J.
In the instant case we confront a question concerning judicial review of adjudicatory determinations of administrative agencies which we were not called upon to reach in Bixby v. Pierno (1971) 4 Cal.3d 130 [93 Cal.Rptr. 234, 481 P.2d 242]. That question, whose presence was expressly noted by us in Bixby (id. at p. 137, fn. 2) is this: When, upon judicial review of an administrative order or decision pursuant to section 1094.5 of the Code of Civil Procedure, it is claimed there has been a prejudicial abuse of discretion in that the findings are not supported by the evidence, what is the proper scope of review when the respondent agency is a local agency or a state agency of local jurisdiction?
If anything has remained consistently clear in the checkered history of the judicial review of administrative decisions under section 1094.5, it has been the answer to the foregoing question. Subdivision (c) of that section provides that when a claim of unsupported findings is made, abuse of discretion (which under subdivision (b) is established if the findings are not supported by the evidence) is shown in cases in which the court is authorized by law to exercise its independent judgment on the evidence if the. court determines that the findings are not supported by the weight of the evidence; in all other cases abuse of discretion is established if the court determines that the findings are not supported by substantial evidence in light of the whole record. It has been veritable gospel, at least since the decision of this court in Standard Oil Co. v. State Board of Equal. (1936) 6 Cal.2d 557 [59 P.2d 119]—which is the fountainhead from which all subsequent law of judicial review of administrative decisions, including section 1094.5 itself, has sprung—that with respect to orders [32]*32or decisions of local agencies or state agencies of local jurisdiction the court is not authorized by law to exercise its independent judgment on the evidence, and therefore that the proper scope of review with respect to such orders or decisions is that of substantial evidence in light of the whole record. It is this axiom which is challenged here today.
After solemn and extended consideration we have concluded that there no longer exists any rational or legal justification for distinguishing with regard to judicial review between, on the one hand, local agencies and state agencies of local jurisdiction and, on the other, state agencies of legislative origin having statewide jurisdiction. Accordingly, we hold that the rule of judicial review applicable to adjudicatory orders or decisions of the latter class of agencies—which was reaffirmed and explained by us in Bixby—is also applicable to adjudicatory orders or decisions of agencies in the former class. That rule is as follows: If the order or decision of the agency substantially affects a fundamental vested right, the trial court, in determining under section 1094.5 whether there has been an abuse of discretion because the findings are not supported by the evidence, must exercise its independent judgment on the evidence and find an abuse of discretion if the findings are not supported by the weight of the evidence. If, on the other hand, the order or decision does not substantially affect a fundamental vested right, the trial court’s inquiry will be limited to a determination of whether or not the findings are supported by substantial evidence in the light of the whole record.
As we explain below, we have concluded that the order and decision in the instant case does affect a fundamental vested right; accordingly the independent-judgment standard stated above is here applicable. Because the trial court in denying the writ considered itself bound by existing law to apply the substantial-evidence standard of review, we reverse the judgment and remand the cause for a new determination under the rule we announce today.

Plaintiff Coreen Strumsky appeals from a judgment denying her petition for a writ of mandate sought to review and set aside the decision of the Board of Retirement (Board)' of defendant San Diego County Employees Retirement Association denying her certain death benefits.
Plaintiff is the widow of Richard D. Strumsky, who died in 1968 follow[33]*33ing surgery to correct a congenital narrowing of the aorta. At the time of his death Mr. Strumsky was a sergeant in the San Diego County Marshal’s office and was in charge of its El Cajon branch; he had been employed by the county for 21 years and for many years had been a “safety member” (see Gov. Code, § 31469.3) of the San Diego County Employees Retirement Association.
Pursuant to the provisions of the County Employees Retirement Law of 1937 (Gov. Code, § 31450 et seq.), plaintiff made application to the Board for the service-connected death allowance established by section 31787 of the Government Code. That section provides in substance and as here relevant that the surviving spouse of a member who dies as the result of an injury or disease arising out of and in the course of his employment is entitled to elect, in lieu of the normal death allowance established by section 31781.1,1 a lifetime allowance amounting to half the member’s salary at death. In the case of Mrs. Strumsky, the service-connected death allowance would be almost three times the nonservice-connected death allowance of $181.03 per month.
The Board held a hearing on the question of service-connection. Five witnesses testified, and documentary evidence, including the written reports of four doctors, was introduced. The evidence established clearly that decedent had suffered from hypertension since boyhood due to a congenital narrowing of the aorta; that this condition was aggravated by progressive arteriosclerosis which had become advanced at a point one year prior to his death; and that the unsuccessful surgery was undertaken in order to correct the aortal narrowing or coarctation and thus relieve the severe hypertension which it and the arteriosclerosis had combined to bring about. There was, however, considerable conflict in the evidence concerning the extent to which the stress and tension inherent in decedent’s occupation and his personal attitude toward his job affected the development of the arteriosclerosis. On this point the evidence ranged widely from an opinion that the stress and tension of decedent’s employment was responsible only to “an infinitesimal extent” for his condition, to an opinion that the arteriosclerosis may have been substantially related to chronic tension. The theory supporting the latter view was that the hypertension caused by decedent’s congenital condition was supplemented and exacerbated by occupational [34]*34tensions and that the heightened hypertension caused by this combination brought about the arteriosclerotic condition.
The Board by a vote of four to three denied Mrs. Strumsky’s application for a service-connected death allowance. Her request for a rehearing was denied, and she thereupon sought review of the decision by administrative mandate. (Code Civ. Proc., § 1094.5.) The trial court denied the writ, finding that “the findings of respondent Board are supported by substantial evidence in the light of the whole record.” The court also made the following supplemental finding of fact: “7. That the Court, if this were a case in which the Court was authorized by law to exercise its independent judgment on the evidence, would find that the death of the decedent safety member Richard D. Strumsky was service-connected in nature.”
The court thus concluded that there was no prejudicial abuse of discretion committed by the Board and that the alternative writ of mandate theretofore issued should be discharged and the petition for the peremptory writ denied. Judgment was entered accordingly. This appeal followed.
II
In Bixby v. Pierno, supra, 4 Cal.3d 130, at pages 144-147, we explained the considerations which counsel in favor of fuller judicial review in cases involving vested, fundamental rights. The essence to be distilled is this: When an administrative decision affects a right which has been legitimately acquired or is otherwise “vested,” and when that right is of a fundamental nature from the standpoint of its economic aspect or its “effect ... in human terms and the importance ... to the individual in the life situation,” then a full and independent judicial review of that decision is indicated because “[t]he abrogation of the right is too important to the individual to relegate it to exclusive administrative extinction.” (Id. at p. 144.)
This reasoning, of course, applies with equal force to all administrative decisions of an adjudicatory2 nature—regardless of the administra[35]*35tive agency involved. It has been held inapplicable, however, in the case of agencies which fall into two categories. The first of these categories is comprised of agencies of constitutional origin which have been granted limited judicial power by the Constitution itself. (See, for example, Boren v. State Personnel Board (1951) 37 Cal.2d 634 [234 P.2d 981]; Covert v. State Board of Equalization (1946) 29 Cal.2d 125 [173 P.2d 545]; Ishimatsu v. Regents of University of California (1968) 266 Cal.App.2d 854 [72 Cal.Rptr. 756]; Palm Springs T. Club v. Cal. Horse etc. Bd. (1957) 155 Cal.App.2d 242 [317 P.2d 713]; cf. Alta-Dena Dairy v. County of San Diego (1969) 271 Cal.App.2d 66 [76 Cal.Rptr. 510].)* *3 In the second category are the agencies with which we are concerned in the instant case, to wit, “local agencies”—which includes both purely local agencies and state agencies of limited territorial jurisdiction. (See, for an example of the latter, Atchison etc. Ry. Co. v. Kings Co. Water Dist. (1956) 47 Cal.2d 140 [302 P.2d 1].) It is established that when review of a decision of an agency falling within either of these two categories is sought pursuant to section 1094.5 of the Cbde of Civil Procedure, the court’s scrutiny of the agency’s factual findings is limited to a determination whether those findings are supported by substantial evidence in light of the whole record —and this is so whether or not the decision of the agency affects a fundamental vested right.
The roots of the indicated distinction insofar as it relates to so-called “constitutional agencies” can be traced to their ultimate source in one of our most fundamental constitutional doctrines, that of separation of powers. That doctrine, which has been a part of the Constitution of this state since its inception, is presently expressed in article HI, section 3 as follows: “The powers of state government are legislative, executive, and judicial. Persons charged with the exercise of one power may not exercise either of the others except as permitted by this Constitution.” (Italics [36]*36added.)4 It is the italicized proviso which forms the basis for the exercise of judicial powers by so-called “constitutional agencies”; insofar as specific constitutional provisions relating to the individual agencies in question directly vest judicial power in them, the agencies so favored can perform judicial functions to the extent of the grant without offending the doctrine of separation of powers. (See Covert v. State Board of Equalization, supra, 29 Cal.2d 125, 132; see also Cal. Administrative Mandamus, supra, §§ 1.3, 5.67, pp. 5, 76.) Thus, even though a vested fundamental right be involved, the determination of the agency on factual issues is entitled to all the deference and respect due a judicial decision.5
With respect to “local agencies” the matter is otherwise. This is so for the simple reason that the separation of powers clause is inapplicable to government below the state level. (People v. Provines (1868) 34 Cal. 520.) Accordingly that clause does not prevent the exercise of judicial powers by “local agencies.” (Imperial Water Co. v. Supervisors (1912) 162 Cal. 14, 17-18 [120 P. 780]; Nicholl v. Koster (1910) 157 Cal. 416, 422-423 [108 P. 302]; Holley v. County of Orange (1895) 106 Cal. 420, 424 [39 P. 790]; Wulzen v. Board of Supervisors, supra, 101 Cal. 15, 25-26; Savage v. Sox (1953) 118 Cal.App.2d 479, 485-487 [258 P.2d 80]; People v. Strong (1931) 114 Cal.App. 522, 527-528 [300 P. 84].) This, however, is not the end of the matter; the fact that agencies below the state level are not prevented from exercising judicial powers by the separation-of-powers doctrine in no way implies in and of itself that they may exercise such powers.6 Because local bodies, like governmental entities on the state level, ultimately derive all their powers from the state Constitution, it is in that document that we must seek the basis for any exercise of judicial power by such bodies.7 If no such basis be found, it matters not [37]*37at all for present purposes that local bodies are not fettered by the separation-of-powers clause in the exercise of the powers which have been conferred upon them.
In the landmark case of Standard Oil Co. v. State Board of Equal., supra, 6 Cal.2d 557, we suggested one possible basis for the exercise of judicial powers by local agencies. The primary holding of that decision, which led to the development of much of our present statutory and decisional law with respect to judicial review of administrative decisions, was that legislatively created agencies of statewide jurisdiction could not under the Constitution exercise judicial powers, and that therefore the decisions of such agencies were not reviewable by certiorari. This holding was based upon article VI, section 1, of the Constitution, which at that time provided as follows: “The judicial power of the State shall be vested in the Senate, sitting as a court of impeachment, in a Supreme Court, district courts of appeal, superior courts, such municipal courts as may be established in any city or city and county, and such inferior courts as the Legislature may establish in any incorporated city or town, township, county or city and county.” (Italics added.) We held, quoting from earlier cases, that “ ‘Except for local purposes the section disposes of the whole judicial power of the state and vests all of it in the courts expressly named therein, leaving none at the disposition of the Legislature.’ ” (Italics added.) (6 Cal.2d at p. 561.) Thus, we concluded, the Legislature could not vest judicial powers in agencies of statewide jurisdiction.
It was the italicized exception, however, which in later cases was seized upon as the basis for a different rule with respect to “local agencies.” (See especially Nider v. City Commission (1939) 36 Cal.App.2d 14, 28 [97 P.2d 293]; see also Fascination, Inc. v. Hoover (1952) 39 Cal.2d 260, 264-265 [246 P.2d 656]; La Prade v. Department of Water & Power (1945) 27 Cal.2d 47, 53 [162 P.2d 13]; Walker v. City of San Gabriel (1942) 20 Cal.2d 879, 881 [129 P.2d 349, 142 A.L.R. 1383]; Corcoran [38]*38v. S. F. etc. Retirement System (1952) 114 Cal.App.2d 738, 740-741 [251 P.2d 59].) The rationale, generally speaking, was that article VI, section 1, while forbidding the exercise of judicial powers by legislatively created agencies of statewide jurisdiction, permitted the Legislature to vest such powers in such “inferior courts” as it might establish on the local level—and that “local agencies” could be considered to be such “inferior courts.” Article XI of the Constitution, which we proceed to examine in some detail infra, clearly allowed the Legislature to establish the powers of local bodies such as counties and cities and to approve the powers delineated in city and county charters. These powers, it was reasoned, might include purely judicial powers pursuant to the grant of article VI.
In 1950, in effecting a reorganization of the inferior courts, article VI, section 1, of the Constitution was amended and the language therein upon which the foregoing cases relied was removed.8
It is the effect of this amendment which is our primary concern today. For the present, however, it is sufficient to observe that the deletion wrought by the amendment rendered the section no longer available as a basis for the exercise of judicial powers by “local agencies.”
Although decided prior to the amendment of article VI, the case of Dierssen v. Civil Service Commission (1941) 43 Cal.App.2d 53 [110 P.2d 513], gave birth to a rationale which has been relied upon since the amendment to support limited judicial review of the factual findings of “local agencies.” Two years earlier in Drummey v. State Bd. of Funeral Directors (1939) 13 Cal.2d 75 [87 P.2d 848], this court, in the course of discussing the Standard Oil decision and its effect on the powers of state agencies of statewide jurisdiction, had made the following statement: “The theory of [Standard Oil] is that, if the Legislature attempted to confer judicial or ^nas/-judicial power [original italics] on state-wide administrative boards, the statutes would be unconstitutional as in violation of section 1 of article VI of the state Constitution, which vests the entire judicial power of the state in the courts, except as to local boards, and the railroad and industrial accident commissions, which are governed by special constitutional provisions.” (Italics added.) (13 Cal.2d at p. 81.) Seizing upon the italicized language, the District Court of Appeal in Dierssen concluded that it related not only to its immediate grammatical antecedent (i.e., “the railroad and industrial accident commissions”) but also to “local boards.” [39]*39The Dierssen court stated: “Quite obviously, what the Supreme Court had in mind when it stated in the Drummey case, supra, that, ‘local boards . . . are governed by special constitutional provisions,’ were the broad provisions of article XI, section 6, of the Constitution dealing with the powers of chartered cities.” (43 Cal.App.2d at p. 60.) The court then went on to examine certain provisions of article XI9 and concluded therefrom: “Under these provisions a chartered city or city and county may lawfully confer quasi judicial power on boards or commissions dealing strictly with municipal affairs, such as the power to determine facts, and, if such finding is made, the courts may interfere only where the board acts arbitrarily, capriciously, or fraudulently. Stated another way, the courts are empowered to interfere with the findings of such boards only where a clear abuse of discretion is alleged and proved. If there is any substantial evidence to support the board’s findings the courts are powerless to interfere. This is apparently the law even as to state-wide boards where the board has fact finding powers and is not attempting to take away an existing right.” (43 Cal.App.2d at pp. 60-61.)
Twelve years later and shortly after the 1950 amendment to article VI, the same District Court of Appeal (although composed of two new members) adopted the rationale of its earlier Dierssen decision as the primary support for differing standards of review in Savage v. Sox, supra, 118 Cal.App.2d 479 [258 P.2d 80]. It was there contended that the effect of the amendment was to remove all constitutional support from the distinction in question. The court, rejecting this contention, quoted extensively from Dierssen. It also made reference to the arguments before the voters at the time of the amendment and conluded that “the voters in reducing the number of inferior courts never intended to, nor did they, in any way interfere with the rights granted municipalities, counties and cities and counties in the other portions of the Constitution.” (118 Cal.App.2d at p. 488.)
We express at the outset our suspicion that the reasoning of Dierssen was grounded to a large extent upon a grammatical misunderstanding of the language of this court in Drummey. The sentence from the latter case which we have quoted above (see text accompanying fn. 9, ante) is concerned with restating the “theory” of Standard Oil, such “theory” being in full effect at the time of Drummey. In the course of such restatement we indeed indicated that the then article VI, section 1 “vest[ed] the entire [40]*40judicial power of the state in the courts* except as to local boards, and the railroad and industrial accident commissions, which are governed by special constitutional provisions.” (13 Cal.2d at p. 81.) It is clear to us, however, that the final clause of eight words in this statement refers only to the seven words next immediately preceding it and not to the phrase concerning “local boards.” The only “special constitutional provision” which Standard Oil had related to local boards was article VI, section 1 itself, a section which, as indicated above, was amended in 1950 (11 years after Drummey) to remove the support which Standard Oil had found in it. Thus it is our opinion that the Dierssen court was misled at the outset in undertaking its search for other constitutional support; all the support necessary at that time was provided by article VI, section 1.
The matter is otherwise when we come to Savage v. Sox, supra. By the time of that decision article VI, section 1 had indeed been amended and new constitutional justification was necessary to replace it, if the distinction in standards of review was to be maintained. The Savage court, by adopting Dierssen, likewise adopted the constitutional supports which had been needlessly “discovered” 12 years before: the home-rule provisions of article XI. These it duly installed as the “new” constitutional source of judicial power in “local agencies.”
The error in the Savage decision is fundamental: it fails to appreciate the relationship between article VI and article XI, and in so doing it totally misapprehends the comprehensive effect of the 1950 amendment on the former article. Article XI does not and cannot stand alone. It invests the Legislature with the authority to bestow powers upon, and to set up procedures for, govemmentál bodies below the state level. This is carried out for so-called general law (i.e., noncharter) cities and counties by direct legislation of statutes found in the Government Code. With respect to charter cities and counties such powers and procedures are prescribed by means of legislative approval or disapproval of the charter presented to the Legislature. In each case, however, the Legislature is limited in the nature and extent of the powers which it may grant. With respect to legislative powers, the question is one of proper delegation of powers vested in the Legislature itself by article IV of the Constitution.10 With respect to executive powers, the question is one of avoiding conflict with the executive powers reserved to members of the executive branch in article V. With respect to judicial powers, the question is one of compli[41]*41anee with the limitations imposed by article VI—a matter which we now proceed to examine in some detail.
As we have indicated above, prior to 1950 article VI permitted the Legislature to establish “inferior courts” on the local level and thus to vest judicial powers to that extent. The Legislature exercised this grant directly by establishing a plethora of local courts at the municipal and township level, including township justice of the peace courts, police courts, city justice of the peace courts, and city courts. In addition, according to the interpretation adopted in Standard Oil and its progeny, it exercised the grant by vesting judicial powers in “local agencies.”
Article XI of the Constitution was (and today remains) the conduit through which the Legislature vested in “local agencies” whatever powers it was entitled to vest in them. It was and is not, as the Dierssen and Savage courts assumed, an independent source of power—rather it was and is the instrument by and through which the Legislature takes the powers it is constitutionally entitled to bestow and in turn bestows them at least in part on governmental units below the state level.
With the foregoing in mind, we focus our inquiry upon the effect of the 1950 amendment to article VI. To begin with, we believe’that the court in Savage v. Sox, supra, correctly concluded that the result of the amendment was in part to withdraw from the Legislature the authority to create and bestow judicial powers upon inferior courts at the local level.11 It is clear that in effect the amendment not only precluded the further creation of such courts but also provided for the gradual elimination of those already established12—resulting in a concentration of judicial power in constitutionally designated courts. However, the Savage court expressly declined to recognize that the amendment had a fuller and more comprehensive effect—in short, that it had the effect of withdrawing from the Legislature the ability to vest judicial power in any body and of concentrating in the court system all judicial power not expressly bestowed elsewhere by the Constitution.13 This result, the Savage court concluded, was not intended [42]*42by the amendment. “The power exerted in this case is a purely municipal affair and the voters in reducing the number of inferior courts never intended to, nor did they, in any way interfere with the rights granted municipalities, counties and cities and counties in the other portions of the Constitution. The elimination of the power of the Legislature to provide other inferior courts [original italics] than the municipal and justice courts still left the constitutional provisions under which the charter of a city and county could lawfully confer quasi-judicial[
As we have suggested, we believe that the analysis of the Savage court suffers from a failure to apprehend the relationship- between articles VI and XI of the Constitution and a mistaken conclusion that the latter article constitutes an independent source of constitutional authority for legislative vesting of judicial power in “local agencies.” On the contrary we have concluded that article VI disposes of all judicial power not expressly disposed of elsewhere in the Constitution, and that, following its amendment in 1950, it no longer authorized the Legislature, in its granting of powers to various local bodies pursuant to article XI, to grant judicial powers. In short, although the Legislature retains the authority to grant a multitude of powers to local bodies pursuant to article XI, powers of a judicial nature are no longer at its disposal.15 Moreover we believe that the amend[43]*43ment to article VI had the effect of withdrawing judicial powers formerly granted pursuant to article XI prior to the amendment, leaving the entire judicial power concentrated in the state court system and some “constitutional agencies.”16
[44]*44The effect of this conclusion upon the question immediately before us is clear. Because judicial powers may no longer be exercised by “local agencies,” the factual findings of those agencies are entitled to no greater deference than those of other agencies lacking judicial powers under the Constitution. Accordingly we conclude that the rule of review which was reaffirmed by us in Bixby v. Tierno, supra, for application to adjudicatory decisions by legislatively created agencies of statewide jurisdiction is equally applicable to decisions by “local agencies” as well.
We therefore hold that in all such cases, if the order or decision of the agency substantially affects a fundamental vested right, the court, in determining under section 1094.5 of the Code of Civil Procedure whether there has been an abuse of discretion because the findings are not supported by the evidence, must exercise its independent judgment on the evidence and find an abuse of discretion if the findings are not supported by the weight of the evidence. If, on the other hand, the order or decision does not substantially affect a fundamental vested right, the trial court’s [45]*45inquiry will be limited to a determination of whether or not the findings are supported by substantial evidence in light of the whole record. So that there will be no misunderstanding, we emphasize that this rule shall apply to all pending and future proceedings in trial courts and all pending and future appeals.
Ill
We have concluded that the decision of the Board in this case substantially affected a fundamental vested right, to wit, plaintiff’s right to receive a service-connected death allowance.
It has long been established that retirement benefit rights of the nature here involved are vested. (See Pearson v. County of Los Angeles (1957) 49 Cal.2d 523, 531-532 [319 P.2d 624]; Wallace v. City of Fresno (1954) 42 Cal.2d 180, 183 [265 P.2d 884]; Dryden v. Board of Pension Commrs. (1936) 6 Cal.2d 575, 579 [59 P.2d 104].) We also believe that the right here in question is not only vested but “fundamental” within the meaning of Bixby v. Pierna, supra. “In determining whether the right is fundamental the courts do not alone weigh the economic aspect of it, but the effect of it in human terms and the importance of it to the individual in the life situation.” (4 Cal.3d at p. 144.) It is the latter consideration which renders the instant right fundamental. Above and beyond the “economic aspect” present in all pension cases, we have here a situation in which the benefits sought might well mean to the officer’s widow the difference between self-support and the necessity that she supplement pension income through employment or other means.17 Thus, the impact in human terms of the decision is manifest.
It is urged, however, that we are here concerned not with the right to death allowance itself but with the amount of the allowance. Whereas the right to an allowance might be considered vested and fundamental, it is argued, the right to an allowance in a particular amount is not. We believe that this objection fails to recognize the realities of the situation before us. Putting to one side the practical consideration expressed above— i.e., that the service-connected allowance provides the possibility of self-support, whereas the residual allowance does not—we think that the statutory scheme governing death benefits for county employees contemplates what are in effect two different benefits, one which is service-connected (Gov. Code, § 31787) and one which is not (Gov. Code, §31781.1). It is true that the wife had no vested right in either of these pensions until [46]*46the happening of the contingency upon which the benefits were payable (see Packer v. Board of Retirement (1950) 35 Cal.2d 212, 215-218 [217 P.2d 660]; Sweesy v. L. A. etc. Retirement Bd. (1941) 17 Cal.2d 356, 361-363 [110 P.2d 37]), but upon the happening of that contingency (i.e., the death of her husband) she acquired a fundamental vested right in one pension or the other—according to whether or not that death was service-connected. It is the latter question which requires a judicial determination under the rule we announce today—a determination which, because the Board lacks the power to make it, must be madd by the court through the exercise of its independent judgment on the evidence produced before the Board.18
The judgment is reversed and the cause is remanded to the trial court for further proceedings consistent with this opinion.
Wright, C. J., Tobriner, J., and Mosk, J., concurred.
“Enforce refers to requiring operation, observance, or protection of laws, orders, contracts, and agreements by authority, often that of a whole government or of its executive or legal branches. . . .” (Webster’s Third New Internat. Dict. (1963) p. 751.)
