Plaintiffs in this case are all retired members of the police or fire department who were employed by defendant city subsequent to July 1, 1925, but prior to January 17, 1927. Each of them served regularly as a member of said police or fire department for an aggregate period of more than 20 years, and was granted and is being paid a fixed service retirement pension pursuant to section 181 of the charter of the City of Los Angeles. By their complaint, which was filed May 29, 1959, plaintiffs sought to obtain a declaratory judgment as against the defendant city and its board of pension commissioners respecting their past and future pension rights and to recover past-due pension benefits. Plaintiffs assert that they are and were from the date of their retirement entitled to receive a fluctuating pension in lieu of the fixed pension paid to them. They also requested the entry of a declaratory judgment as to the rights of their widows or other dependents to receive a fluctuating death benefit pension upon their demise. Reference is made to the cases of
Henry
v.
City of Los Angeles, ante,
p. 299 [
In its memorandum opinion and order, findings and judgment the trial court, in respect to the issues presented on this appeal:
(1) Rejected plaintiffs’ contention that the 1925 change from fluctuating to fixed pensions was invalid and unconstitutional as to plaintiffs since the plaintiffs, employed after July 1, 1925, acquired no “vested contractual rights” to fluctuating pensions;
(2) Held that plaintiffs, who retired prior to June 16, 1947, have always been entitled, from date of retirement to June 16, 1947, to fixed pensions based upon the pre-1927 formula, to wit, a percentage of the annual salary of the rank held one year prior to date of retirement and, from *329 June 16, 1947, pursuant to the 1947 amendment, they have been entitled to receive fluctuating pensions based upon the current salaries of the average ranks held during the three years immediately preceding date of retirement, and they are entitled to recover, from date of retirement, the differences between such pensions and those which had been paid to them because the pension fund is a trust fund and the time provided in applicable statutes of limitation and charter claim sections did not commence to run until plaintiffs’ claims were rejected by the pension board;
(3) Held that plaintiffs who retired subsequent to June 16, 1947, have always been entitled, from date of retirement, to fluctuating pensions based upon the current salaries of the average ranks held during the three years immediately preceding date of retirement, and they are entitled to recover, from date of retirement, the differences between such pensions and those which have been paid to them because the pension fund is a trust fund and the time provided in applicable statutes of limitations and charter claim sections did not commence to run until plaintiffs’ claims were rejected by the pension board;
(4) Held that the widows of plaintiffs, if married at least one year prior to date of retirement, shall be entitled to fluctuating pensions based upon the 1947 formula, to wit, the current salaries of the average ranks held during the three years immediately preceding date of retirement, provided that should the pension payable under the pre-1927 formula (salary attached to the rank held one year prior to retirement) be greater than that payable under the 1947 formula, then each widow or other dependent, except the widows or other dependents of the plaintiffs Hales, James and Volkman, shall be entitled to fluctuating pensions computed on said pre-1927 formula;
(5) Held that because of the confidential relationship existing between pensioners and the city defendants are estopped to urge the bar of the statute of limitations and charter claims sections; and
(6) Adopted plaintiffs’ running account theory in respect to the bar of section 376 of the city charter.
Defendants contend on appeal the trial court erred in the following respects:
(1) In holding the trust fund theory applicable to the fire and police pension fund of the City of Los Angeles so as *330 to suspend application of statutes of limitation and charter claims sections to claims for increased pensions;
(2) In holding the 1947 amendment to the city charter (Stats. 1947, pp. 3679-3687) created fluctuating pensions to which all plaintiffs, whether retired prior thereto or not, and their widows, are entitled, and in so determining in the face of the fact that this was not an issue in the case;
(3) In holding the formula for computing fixed pensions adopted in 1927, to wit, average monthly rate of salary received during the three years immediately preceding retirement, is invalid and unconstitutional in respect to members (and their dependents) whose employment began prior to January 17, 1927, and such plaintiffs are entitled to have their pensions calculated on the pre-1927 formula, to wit, annual salary of the rank or position held one year prior to retirement;
(4) In holding widows of plaintiff members who commenced their employment prior to January 17, 1927, are entitled to have their fluctuating pensions calculated upon either the pre-1927 or 1947 formula, whichever results in the greater pension;
(5) In holding defendants are estopped to assert the bar of the statute of limitations and charter claims sections;
(6) In holding the running account theory applicable to claims for increased pensions so as to prevent the running of the time provided in the claims section of the city charter (§ 376); and
(7) In entering judgment solely against the board of pension commissioners (not the City of Los Angeles, a party hereto) and in limiting payment of said judgment solely out of the reserve presently existing in the fire and police pension fund.
Plaintiffs contended in the trial court the relationship between the pension board and retired pensioners is that “of a trustee under an express trust” and therefore “the statute of limitations is not a bar in this case until there has been an express repudiation by the Pension Board of its obligations to adjust these accounts, and that that repudiation did not occur until they rejected the claims of these plaintiffs in the cases at bar, which, of course, occurred just a month or two before the action was filed.” In its memorandum opinion and order the trial court based its approval of plaintiffs’ trust fund theory upon the provisions of the city charter *331 and sections 2221 and 2222 of the Civil Code which pertain to the creation of voluntary trusts.
The trial court, in commenting upon
Abbott
v.
City of Los Angeles,
Nearly all contracts embrace a certain degree of trust relationship, as does every agency, but it does not follow that each creates a trust.
(Grotefend
v.
May,
The sections of the Civil Code pertaining to voluntary trusts are applicable solely to private trusts
(Estate of Sutro,
It is a general rule of construction that a statute having special application controls a general one.
(Chilson
v.
Jerome,
In
Nicols
v.
Police Pension Fund Comrs.,
In an express voluntary trust there must be a subject or trust res, i.e., the trustor must set aside some specific real or personal property. (Civ. Code, §§ 2220-2222; 48 Cal. Jur.2d 664-665.) When the property in the trust is exhausted the trust is extinguished and the trustee’s duties in connection therewith are at an end because the object of the trust has become impossible of accomplishment. (Civ. Code, §§ 2279, 2282.) Likewise, if the pension fund is an ordinary voluntary express trust within the meaning of the Civil Code sections referred to, as held by the trial court herein, the trust could be revoked at any time by the trustor city pursuant to section 2280 of the same code. However, under the law, pensions must be paid because they constitute contractual obligations imposed by law and are general obligations of the city.
In
Kern
v.
City of Long Beach,
The pension fund of the defendant city, unlike an ordinary trust, may never be permanently exhausted and thus terminated. The city is obligated to meet all of its lawful pension demands by resort to taxation, (Los Angeles City Charter, §§ 186, 186.2.)

In
England
v.
City of Long Beach,
MacMullan
v.
Kelly,
For the reasons stated in the cases of
Henry
v.
City of Los Angeles, ante,
p. 299 [
We approve the holding of the trial court that the formula for computing fixed pensions adopted in 1927, to wit, average monthly rate of salary received during the three years immediately preceding retirement, is invalid and unconstitutional in respect to members (and their dependents) whose employment began prior to January 17, 1927, and that such plaintiffs are entitled to have their pensions calculated on the pre-1927 formula, to wit, annual salary of the rank of position held one year prior to retirement.
Defendants contend the trial court erred in its holding that prospective widows of plaintiff members who commenced their employment prior to January 17, 1927, are entitled to have their fluctuating pensions calculated upon either the pre-1927 formula (under which pensions were to be based upon a percentage of the annual salary of the rank held one year prior to retirement) or the 1947 formula (which bases pensions upon a percentage or average monthly rate of salary
*334
assigned to the ranks held during the three years before retirement) whichever results in the greater pension. However, under the reasoning of the Supreme Court in the
Abbott
case,
supra,
and as applied by this court in the cases of
Henry
v.
City of Los Angeles, ante,
p. 299 [
With reference to the issue of estoppel as raised by plaintiffs in this case the court found certain actions and conduct on the part of defendants had the effect of estopping the defendants from asserting the defense of the statute of limitations and the claims section of the charter. The facts found by the court were substantially as found by the trial court on the same issue in
Henry
v.
City of Los Angeles, ante,
p. 299 [
We agree with the contention of defendants that the running account theory is not applicable to claims for increased pensions so as to prevent the running of the time provided in the claims section of the city charter (§ 376). As material to this point, section 376 of the city charter provides, “. . . all claims for damages against the city must be presented within six (6) months after the occurrence from which the damages arose, and all other claims for damages shall be presented within six (6) months after the last item of the account or claim accrued. ’' Plaintiffs contend each monthly underpayment of a pension amount is part of a running account composed of many items and such items accumulate so that the last item in the account includes all past underpayments. With this contention, the trial court concurred. It is well settled, however, that the payment of salaries or pensions by a city is not a back or credit account and each payment thereof is a cash transaction. If any mistake arises in respect to any individual payment a cause of action accrues immediately.

The open book account theory was rejected in
Gamble
v.
City of Sacramento,
In the
Abbott
case,
supra,
the defendants herein contended successfully, relying upon
Dillon
v.
Board of Pension Comrs.,
We approve defendants’ final contention that the trial court erred in entering judgment solely against the board of pension commissioners and in limiting payment of the judgment solely out of the reserve presently existing in the fire and police pension fund, since it is well settled the obligation to pay pensions is an obligation imposed by law upon the city.
(England
v.
City of Long Beach, supra,
The judgment herein must be against the city and not against the pension fund or its administrators. The judgment is affirmed in part and reversed in part and is remanded to the trial court with instructions to enter judgment in conformity with the views expressed herein.
Jefferson, J., and Balthis, J., concurred.
A petition for a rehearing was denied March 28, 1962, and respondents’ petition for a hearing by the Supreme Court was denied May 16,1962.
