BOSTON EDISON COMPANY vs. CITY OF BOSTON.

LYNCH, J. This case raises the issue whether the city of Boston, a municipal consumer of electric power, may be charged interest when it fails to pay its bills on time. A judge in the Superior Court found that the city was liable for interest, but only on bills that came due after June 27, 1977, the effective date of St. 1977, c. 328, amending G. L. c. 164,

Page 773

Section 94D. He therefore allowed partial summary judgment in favor of Boston Edison Company (Edison). Both parties have appealed from this judgment. The city claims that it cannot be charged interest, the provision of Section 94D notwithstanding, while Edison argues that the city is liable for interest as of February 19, 1975, [Note 1] when the Department of Public Utilities (department) approved a general interest charge for nonresidential customers. Edison's appeal is before this court on direct appellate review; the city's appeal was transferred to this court on our own motion. The partial judgment in favor of Edison is affirmed and the case is remanded to the Superior Court for the entry of a further judgment in Edison's favor consistent with this opinion.

The facts are straightforward. The city purchases electricity from Edison for numerous buildings and facilities. There is no written contract between the parties, but the city pays for whatever electricity it uses according to the rates and charges filed with and approved by the department pursuant to G. L. c. 164, Section 94. In February, 1975, the department's order became effective which approved the collection of a late payment charge of 1 1/2% a month by Edison and other utilities for accounts that were overdue by twenty-five days or more. DPU 18248. On June 27, 1977, St. 1977, c. 328, became effective, which provided that late charges could not be collected from the Commonwealth or any municipal customer until the bill had been overdue fifty-five days. [Note 2] During the relevant period (1975 to the present),

the city has incurred late charges for overdue accounts but has refused to pay Edison any amount claimed to be due as interest.

1. Statutory history. The provision of electricity in Massachusetts is thoroughly regulated. The process of utility rate making by a public regulatory body is the exercise of a legislative function, Boston Real Estate Bd. v. Department of Pub. Utils., 334 Mass. 477, 482 (1956), which has been delegated to the department through the enactment of G. L. c. 164. Specifically, G. L. c. 164, Section 94, authorizes the department to prescribe the "rates, prices and charges" which utilities may charge. General Laws c. 164, Section 94D, concerns penalties and late charges for overdue accounts. As originally enacted in 1936, Section 94D prohibited the collection of penalties from residential consumers. St. 1936, c. 243. [Note 3] There is no indication that Edison included late charges in its rate schedule until 1975 when it, along with four other utilities, petitioned the department to approve an interest charge of 1 1/2% a month for accounts overdue more than twenty-five days. The department approved this change, citing the increase in the numbers of accounts receivable outstanding for more than thirty days, "especially from industrial and commercial customers." DPU 18248.

In 1977, a second paragraph was added to Section 94D. St. 1977, c. 328. [Note 4] The legislative history makes it clear that the General Court was concerned about the imposition of late charges on State and municipal agencies and wished to extend

Page 775

the grace period from twenty-five to fifty-five days. There were proposals that State and municipal consumers be exempted from interest charges. 1977 House Doc. No. 3120, at 1-2. 1977 House Doc. No. 5581, at 1.

This review of the statutory history and the order of the department identifies the three distinct time periods at issue in this case. It is agreed that prior to the approval of general late charges as part of the rate schedule in 1975 (DPU 18248), Edison could not charge the city interest on overdue accounts. Between February 19, 1975, and June 27, 1977, if Edison could collect interest from the city, it would be on the authority of DPU 18248. Interest would start to accrue when the bills were overdue twenty-five days. After June 27, 1977, it would be on the authority of DPU 18248 and St. 1977, c. 328, and interest would start to accrue after fifty-five days. Edison argues that it can collect interest according to this scheme. The city argues that neither the order of the department nor the 1977 amendment to G. L. c. 164, Section 94D, gives Edison the authority to assess a late charge for its overdue accounts.

2. The period subsequent to June 27, 1977. We address the most recent period first. The city maintains that even the straightforward language of St. 1977, c. 328, does not obligate it to Edison for interest payments because the city is governed by a special statute, the City of Boston Code (Code), which requires all contracts for more than $2,000 to be in writing and approved by the mayor. City of Boston Code, Statutes, tit. 4, Section 8 (1975). Furthermore, Title 4, Section 4, prohibits expenditures in excess of appropriations. The city argues that the Code, since it is a special law, overrides the provisions of the general law. Although there is some support for this argument, see Haffner v. Director of Pub. Safety of Lawrence, 329 Mass. 709, 713-714 (1953), we have also recognized that local laws are superseded by statutes that deal comprehensively with a Statewide problem, and that utility regulation is one type of comprehensive legislation that preempts local ordinances. New England Tel. & Tel. Co. v. Lowell, 369 Mass. 831, 834-835 (1976).

Whether the laws regulating utilities take precedence over inconsistent special laws, such as the Code, we conclude that in this case the provisions of the Code do not conflict with G. L. c. 164, Section 94D. This is so because, first, the provision of electricity to the city is not a relationship where the special contract requirements are implicated, and second, it is not an expenditure for which budgetary appropriation must be made in the regular way.

a. Contracts must be in writing and approved by the mayor. The city claims that it cannot be required to pay interest on its overdue electric bills because it has no written contract with Edison. [Note 5] It cites several cases where the requirements of tit. 4, Section 8 (or comparable ordinances or bylaws of other municipalities), were strictly and absolutely adhered to, despite an unfair result. See, e.g., Urban Transp., Inc. v. Mayor of Boston, 373 Mass. 693, 696-697 (1977) (even after providing bus service to the city for three years, plaintiff could not recover because contract had never been approved by mayor); Central Tow Co. v. Boston, 371 Mass. 341, 343-344 (1976) ("No doubt it was most imprudent of the parties not to have entered into an express contract... [t]hat the parties were neglectful, however, did not repair the absence of the elements, fixed by statutes, which were essential here to the formation of a contract"); Adalian Bros. v. Boston, 323 Mass. 629, 632 (1949) ("It is... settled that limitations on the contracting power of municipal officers cannot be evaded by first rendering services or furnishing supplies without an express contract and then claiming under an implied contract").

This argument would be convincing if the service provided by Edison were one for which a contract is appropriate. The Appeals Court faced precisely this issue in Boston Gas Co. v. Boston, 13 Mass. App. Ct. 408, S.C., 386 Mass. 1102 (1982), and we fully agree with the court's analysis in that case. None of the reasons for requiring the safeguards of a

Page 777

written contract approved by the mayor is applicable here. The city must have electricity, and unless it generates its own, Edison is the only possible source. Since Edison has a legislatively sanctioned monopoly, there could never be competitive bidding. The rates themselves are set legislatively and cannot be altered by the parties. New York, N.H., & H.R.R. v. York & Whitney Co., 215 Mass. 36 (1913). When a utility wants to change its rates, it must file a schedule with the department. G. L. c. 164, Section 94. A consumer's challenge to a rate must be filed through the department, not the courts. Sullivan v. Boston Consol. Gas Co., 327 Mass. 163, 167 (1951). Thus there can be no negotiation between the parties as to rate. [Note 6] The result of regulation this extensive is that it "takes that subject out of the realm of ordinary contract in some respects, and places it upon the rigidity of a quasi statutory enactment." Haverhill Gas Co. v. Findlen, 357 Mass. 417, 420 (1970), quoting from New York, N.H., & H.R.R. v. York & Whitney Co., 215 Mass. at 40-41.

The purpose of tit. 4, Section 8, is "to limit the power of public officials in making contracts... so as to unify the control of the city's commercial transaction... and guard against waste by departments in the government" (citations omitted). Urban Transp., Inc. v. Mayor of Boston, supra at 697. This purpose would not be served by applying the terms of tit. 4, Section 8, to the obligation of the city to pay interest on overdue electric bills.

b. Expenses in excess of appropriation. Much the same analysis applies to the city's appropriation argument as applied to its contract argument, with much the same conclusion. Title 4, Section 4, prohibits the expenditure by any official of an amount in excess of lawful appropriations by the city

Page 778

council. The purpose of this requirement, like that of the contract requirement, is to prevent individual officials from incurring indebtedness for which the city has not provided and "to place the supervision and control of the expenditure of [public] funds upon the [city] through the medium of a budgetary system." Baker v. Commonwealth, 312 Mass. 490, 493 (1942). Like the contract requirement, this requirement is strictly enforced, even when the result is that the city is unjustly enriched. Rich & Son Constr. v. Saugus, 355 Mass. 304 (1969). Dyer v. Boston, 272 Mass. 265 (1930). Like the contract requirement the purposes of this requirement would not be served by applying it here. The city would have no control over the amount allocated for electricity in any event. As noted above, the price is nonnegotiable and it would be impossible for the city to predict how much electricity it would need for a year. Even if it were to appropriate an amount based on the previous year's usage, if the department were then to allow a rate increase, the appropriation would be obsolete. See Boston Teachers Local 66 v. School Comm. of Boston, 386 Mass. 197 (1982) (inadequate appropriation does not bar subsequent raise in teachers' salaries). [Note 7]

Furthermore, it is clear that a municipality cannot use an indebtedness statute to avoid paying its bills simply by refusing to appropriate sufficient funds. In Salisbury Water Supply Co. v. Salisbury, 341 Mass. 42 (1960), for example, the court refused to allow the town to escape its obligations under contracts with the water company because its appropriations were insufficient.

Page 779

We therefore conclude that tit. 4, Sections 4, 8, do not prohibit the expenditure of funds to pay for interest on overdue accounts incurred by the city in accordance with properly approved rates and charges.

3. The period between February 19, 1975, and June 27, 1977. Since it is clear that G. L. c. 164, Section 94D, and DPU 18248 permit the collection of interest by Edison from the city on accounts overdue at least fifty-five days, it is equally clear that the city was liable for interest on accounts overdue at least twenty-five days after the interest proposal was approved in 1975 but before the 1977 amendment. The purpose of the statute was to extend the time the city had to pay its bills before incurring late charges. That makes no sense if the city were not already liable for interest charges. [Note 8] The Legislature clearly assumed that DPU 18248 did apply to municipal consumers. The order itself does not suggest otherwise. It refers to the increased problem with overdue bills, particularly from commercial and industrial customers, but is applicable to all accounts receivable except those of residential customers, in accordance with G. L. c. 164, Section 94D, as then amended.

The judge in the Superior Court found that the department did not have the statutory authority to require the city to pay interest, that being a matter of municipal finance. As is clear from the discussion above, however, the department has explicit statutory authority, both to set prices and to establish conditions of service. G. L. c. 164, Section 94. See note 6, supra. If the department had the authority to decide how much the city should pay for the electricity itself, which is undisputed, it also had the authority to approve the late charges.

The partial judgment of the Superior Court in favor of Edison is affirmed and the case is remanded to the Superior Court for the entry of further judgment consistent with this opinion.

So ordered.
