PURITY SUPREME, INC. vs. ATTORNEY GENERAL (and a companion case [Note 1]).

QUIRICO, J. These cases were commenced by two complaints, one filed by the Attorney General seeking to enforce against Purity Supreme, Inc. (Purity), the Attorney General's Regulation XII (A) (1) (regulation), promulgated by him pursuant to his authority under G. L. c. 93A, Section 2 (c), and the other filed by Purity against the Attorney General seeking a declaration that the regulation is unconstitutional and otherwise invalid. The cases were submitted to a judge of the Superior Court on the pleadings and on an agreement of all material facts. Thereafter the judge, at the written request of the parties, reported the cases to the Appeals Court, without decision, and they are now before us as the result of our allowance of the request of one of the parties for direct appellate review. [Note 2]

The cases present an important question concerning the power of the Attorney General to promulgate substantive rules of law pursuant to G. L. c. 93A, Section 2 (c). In our judicial review of the regulation, we do not concern ourselves with its wisdom or expediency, but only with its validity and constitutionality. We hold that the regulation is a valid exercise of the Attorney General's power under G. L. c. 93A, Section 2 (c), with the force of law normally accorded to an agency's regulations, and that it is not unconstitutional as applied to Purity.

The regulation, which is sometimes referred to as the Item Price Regulation, was promulgated in 1971. It requires

Page 764

merchants to affix the sale price to each item of consumer goods. [Note 3] In February, 1977, Purity opened a retail store, which it called the Heartland Food Warehouse (Heartland), in Salem, Massachusetts. Heartland offers for sale groceries, household items, dairy products, meat, frozen food and produce. All items except delicatessen items are sold on a self-service basis. At the time the parties agreed to material facts, approximately eighty-one per cent of the items offered for sale had no price affixed to the individual item. Instead, Heartland notified the consumer of prices by signs on cartons or shelves which contained the items. Pencils were provided so that a consumer could mark each item if he so chose.

Heartland utilizes the Universal Product Code (UPC), a computerized checkout system. Imprinted on each item for sale is a symbol unique to that item, consisting of a series of short, black lines varying in width, darkness and density. The coded information identifies each item. Special electronic scanners "read" this information at the checkout counter, and a computer preprogrammed with the price of each item translates the scanned symbol and causes the special cash register to display visually the item description and price, and to print out that information on the register tape. The consumer receives a copy of this tape, and thus, for ninety-one per cent of the items thus sold, his record of purchases contains abbreviated descriptions of each item next to the price, as opposed to the present commonly known register tape showing a list of prices only. [Note 4] Price changes can be made only at the computer terminal.

Page 765

At the time the Attorney General promulgated the regulation, neither the UPC nor any electronic checkout system was commercially available. [Note 5] The parties have agreed that the Attorney General knows of no fact tending to prove that the UPC system has caused any consumer to suffer actual financial loss, or that the system is per se "unfair" or "deceptive" within the meaning of any common law or statutory concept, including G. L. c. 93A. Nor has the Attorney General conducted any investigation to ascertain if there are any such facts.

Purity argues that it is technically in compliance with the regulation, because it affixes the price "at the point of customer decision [to purchase]," and visually displays the price on the cash register and the printout tape. Should that argument fail, it asserts that the regulation is "legislative" and not "interpretive" and therefore exceeds the Attorney General's statutory authority. Purity contends that even if the Attorney General has the power to promulgate regulations which are legislative in nature, this regulation fails because it is not aimed at regulating practices which are "unfair" and "deceptive" and because the regulation is inconsistent with decisions of the Federal Trade Commission (FTC) and court decisions interpreting the FTC Act, 15 U.S.C. Sections 41 et seq. (1976). Finally, Purity attacks the procedure through which the regulation was adopted, and raises constitutional objections.

1. Source of Attorney General's power. The Attorney General's power to seek injunctive relief derives from G. L. c. 93A, Section 4. Jurisdiction is also conferred on this court by Section 4, and by G. L. c. 231A, Section 1. Also, G. L. c. 30A, Section 7, as appearing in St. 1974, c. 361, Section 3, provides that with certain exceptions not here material, "judicial review of any regulation ... may be had through an action for declaratory relief in the manner and to the extent provided under chapter two hundred and thirty-one A." See

Page 766

Cambridge Elec. Light Co. v. Department of Pub. Utils., 363 Mass. 474, 502 (1973).

General Laws c. 93A is a comprehensive statute for the regulation of consumer and business transactions. "It is a statute of broad impact which creates new substantive rights and provides new procedural devices for the enforcement of those rights." Slaney v. Westwood Auto, Inc., 366 Mass. 688, 693 (1975). Section 1 of c. 93A provides certain definitions, and Section 2 (a), inserted by St. 1967, c. 813, Section 1, states the substantive core of the act: "Unfair methods of competition and unfair or deceptive acts or practices in the conduct of any trade or commerce are hereby declared unlawful." Neither Section 1 nor Section 2 defines "unfair" or "deceptive," however, or indicates what "acts" are prohibited. Rather, Section 2 (b) provides that "courts will be guided by the interpretations given by the Federal Trade Commission and the Federal Courts to section 5 (a) (1) of the Federal Trade Commission Act (15 U.S.C. 45 [a] [1]), as from time to time amended." Further, Section 2 (c) states that "[t]he attorney general may make rules and regulations interpreting the provisions of subsection 2 (a) of this chapter." The Attorney General's power to promulgate rules and regulations is limited by Section 2 (c) only to the extent that such rules shall not be inconsistent with FTC and Federal court interpretations of the FTC Act mentioned in Section 2 (b).

Chapter 93A was enacted in 1967, partly in response to an FTC policy to stop unfair practices on a State level before they become interstate problems. H. Alperin & R. Chase, Consumer Rights and Remedies Section 111, at 253 & n.1 (1979). Section 2 (a) of c. 93A contains language identical to that of Section 5 (a) (1) of the FTC Act (15 U.S.C. Section 45[a][1] [1976]). The Massachusetts statute thus incorporates the extensive body of Federal administrative and decisional law under the FTC Act, Slaney, supra at 694 n.8, at least in so far as it relates to definitions of "unfair" and "deceptive."

2. Status of Federal Trade Commission rules. In 1973 the United States Court of Appeals for the District of Columbia held that the Federal act confers on the FTC the power to

Page 767

promulgate trade regulations which have the force and effect of substantive law. National Petroleum Refiners Ass'n v. FTC, 482 F.2d 672 (D.C. Cir. 1973), cert. denied, 415 U.S. 951 (1974). [Note 6] The court examined concededly ambiguous legislative history from the time the FTC Act was first passed in 1914, and concluded that Section 6(g) of the Act, 15 U.S.C. Section 46(g) (1970), which stated that the Commission "shall also have power -- ...[f]rom time to time ... to make rules and regulations for the purpose of carrying out the provisions of sections 41 to 46 and 47 to 58 of this title," should be liberally construed consistent with the background and purpose of the FTC Act. Id. at 689, 698. That purpose was to create a commission with independent enforcement powers against unfair or anticompetitive business practices. Id. at 687, 691. [Note 7] Partly in response to National Petroleum, Congress in 1975 passed the FTC Improvements Act, Pub. L. No. 93-637, 88 Stat. 2193 (1975), codified at scattered sections of 15 U.S.C. The 1975 act granted the FTC new power to seek civil penalties for violation of its own rules and cease and desist orders, to seek restitution for consumers, and to make "rules which define with specificity acts or practices which are unfair or deceptive"

Page 768

and rules "for the purpose of preventing such acts or practices." [Note 8]

3. Status of Attorney General's regulations. Before National Petroleum, Federal courts had held that FTC rules were only guides, e.g., FTC v. Mary Carter Paint Co., 382 U.S. 46, 47-48 (1965), and directory rather than mandatory, e.g., Floersheim v. Weinburger, 346 F. Supp. 950, 952-953 n.4 (D.D.C. 1972). Purity is in effect asking us to adopt the position of the Federal courts prior to the National Petroleum decision. That position is that, while the definitions of "unfair competition" or "unfair or deceptive acts" promulgated by the designated agency are entitled to deference, courts ultimately are responsible for giving substantive content to the applicable enabling statute. See FTC v. Texaco, Inc., 393 U.S. 223, 226 (1968). We believe this position is inconsistent with the purposes of c. 93A and with our decisions regarding the legal force of other agencies' regulations, and we decline to adopt it.

a. Legal status of other agencies' regulations. This court has on occasion held expressly that agency regulations have the "force of law." See Commonwealth v. Cerveny, 373 Mass. 345, 353 (1977) ("[T]he regulations [of the Rate Setting Commission] should be taken as `law'... unless, indeed, there was something in the statute describing the powers of the [Commission] that stood in the way..."); DaLomba's Case, 352 Mass. 598, 603 (1967) (rules promulgated pursuant to legislative grant of power "generally have

Page 769

the force of law"). See also Niles v. Boston Rent Control Adm'r, 6 Mass. App. Ct. 135, 149 (1978). We have frequently held that properly promulgated agency regulations are to be tested on review in the same manner as a statute. See, e.g., Consolidated Cigar Corp. v. Department of Pub. Health, 372 Mass. 844, 855 (1977); Colella v. State Racing Comm'n, 360 Mass. 152, 155-156 (1971).

Our decisions expressly or implicitly granting agency regulations status as "law" do not distinguish among word choices in the applicable enabling statutes. See Levy v. Board of Registration & Discipline in Medicine, 378 Mass. 519, 524 (1979) ("shall, after proper notice and hearing, adopt rules and regulations governing the practice of medicine in order to promote the public health, welfare, and safety") (St. 1975, c. 362, Section 3); Cerveny, supra ("shall promulgate rules and regulations for the administration of its duties and the determination of rates") (St. 1968, c. 492, Section 3); Consolidated Cigar Corp., supra ("shall establish, by promulgation of regulations, such minimum standards relating to the rights of visitation under this section as will ensure the adequate protection of said rights") (G. L. c. 111, Section 128H, as amended by St. 1971, c. 373); Commonwealth v. Racine, 372 Mass. 631 (1977) ("shall provide by regulation for the implementation by local boards of health, [sanitary] code enforcement agencies and housing inspection agencies of the provisions of this section") (G. L. c. 111, Section 198, as amended by St. 1974, c. 449, Section 2); Cambridge Elec. Light Co., supra ("may establish from time to time such reasonable rules and regulations consistent with this chapter as may be necessary to carry out the administration thereof") (St. 1969, c. 645); Colella, supra at 152 ("shall have full power to prescribe rules, regulations and conditions under which all horse or dog races...shall be conducted") (G. L. c. 128A, Section 9, as amended by St. 1971, c. 96); DaLomba, supra ("may make rules consistent with this chapter for carrying out its provisions") (G. L. c. 152, Section 5, as amended through St. 1972, c. 233).

b. Authority of Attorney General to promulgate regulations under c. 93A. The legislative history of c. 93A does

Page 770

not illuminate the issue before us; indeed, there is almost no published material which sheds light on the intent of the Legislature in passing c. 93A. [Note 9] Therefore we must look to other sources of State law.

The Attorney General's office is an "agency" as defined in the State Administrative Procedure Act, G. L. c. 30A, Section 1 (2). An agency's powers to promulgate regulations "are shaped by its organic statute taken as a whole and need not necessarily be traced to specific words." Cerveny, supra at 354. Levy, supra.

Purity argues that the use of the word "interpreting" in Section 2 (c) indicates a legislative intent to restrict the Attorney General to issuing legal opinions and guidelines which do not have the force of law, and maintains that the regulation is "legislative" and therefore exceeds the statutory rulemaking power of the Attorney General. The State Administrative Procedure Act, however, defines "regulation" as including "the whole or any part of every rule, regulation,

Page 771

standard or other requirement of general application and future effect, including the amendment or repeal thereof, adopted by an agency to implement or interpret the law enforced or administered by it..." (emphasis supplied). G. L. c. 30A, Section 1 (5). Chapter 30A mandates certain procedures for the agency adoption of regulations, and these procedures are discussed later in this opinion. The Attorney General's office is an "agency" under G. L. c. 30A, Section 1 (2). Therefore the Attorney General's regulations are to be treated the same as those of any other agency of the State.

Furthermore, the use of the word "interpreting" does not signify on its face that the Attorney General is limited to advisory opinions, and that legally binding interpretations of "unfair" or "deceptive" must be made in the first instance by the reviewing court. Cf. Cleary v. Cardullo's, Inc., 347 Mass. 337, 342-345 (1964). The purpose of an open-ended legislative use of the words "unfair" and "deceptive" was to allow for the regulation of future, as-yet-undevised, business practices. [Note 10] See Commonwealth v. DeCotis, 366 Mass. 234, 242 (1974). The Attorney General is not constrained to propose abstract definitions of the words "unfair" or "deceptive"; rather, he is to identify particular business practices as falling within their scope. The only limitations on his interpretive power are that his definitions not be inconsistent with FTC and Federal court decisions (G. L. c. 93A, Section 2 [c]), and the usual limitations that his regulations be neither arbitrary nor capricious. That the Legislature intended the Attorney General's regulations to set standards the violations of which would constitute violations of c. 93A is consistent with the over-all purpose of

Page 772

c. 93A and with both FTC practice and the practice in other States. [Note 11]

c. Judicial notice. In York v. Sullivan, 369 Mass. 157, 160 n.2 (1975), we stated that this court will not take judicial notice of the Attorney General's regulations. This was not because they had no force of law, but because it was then the rule in Massachusetts that a court could not take judicial notice of administrative regulations. [Note 12] Passanessi v. C.J. Maney Co., 340 Mass. 599, 604 (1960). Diaduk's Case, 336 Mass. 5, 7 (1957). Finlay v. Eastern Racing Ass'n, 308 Mass. 20, 27 (1941). See also G. L. c. 233, Section 75 (simplifying proof of administrative regulations but making them admissible

Page 773

in evidence). [Note 13] But see Cohen v. Assessors of Boston, 344 Mass. 268, 269 (1962). Therefore York does not preclude our holding that the Attorney General's regulations under c. 93A have substantive legal effect.

d. Expertise. Purity contends also that the Attorney General's office differs from the FTC in that the latter possesses greater expertise. It is true that one rationale of Federal courts for according legally binding status to FTC rules is that the FTC is "an expert body charged with the practical application of the statute." FTC v. Texaco, Inc., supra. Although the record before us is silent on the question of the "expertise" of the Attorney General and his staff in the areas of trade, commerce, and consumer protection, [Note 14] Purity has shown nothing which would justify treating the Attorney General's office differently from other State agencies under the State Administrative Procedure Act. See generally Slaney, supra at 698 (discussion of consumer protection division of Attorney General's office); Richardson, The Office of the Attorney General: Continuity and Change, 53 Mass. L.Q. 5, 20 (1968). [Note 15]

Page 774

e. Conclusion: legal status of the regulation. We have not before faced the question whether the Attorney General's regulations under c. 93A have the force of law and the corollary whether an act or practice which violates a regulation also violates c. 93A. In several cases where plaintiffs in trial courts have alleged in their complaints that an act or practice violated c. 93A, Section 2, and a regulation of the Attorney General, this question was not raised by the litigants and therefore was not discussed by us. See, e.g., Chakrabarti v. Marco S. Marinello Assocs., 377 Mass. 419, 421 (1979); J. & J. Enterprises, Inc. v. Martignetti, 369 Mass. 535, 536-537 (1976). See also Linthicum v. Archambault, 379 Mass. 381, 387 (1979); Heller v. Silverbranch Constr. Co., 376 Mass. 621, 626-627 (1978); York, supra at 160 (demand letter); Slaney, supra at 702.

Commonwealth v. Diaz, 326 Mass. 525, 527 (1950), reaffirmed the principle "that the Legislature may delegate to a board or an individual officer the working out of the details of a policy adopted by the Legislature." See Racine, supra at 635. [Note 16] It is undisputed that the Attorney General could not have promulgated a regulation disallowing a practice expressly permitted by State statute. See Commonwealth v. Rivkin, 329 Mass. 586, 588-589 (1952) (total prohibition of sidewalk sale of ice cream by local health board exceeds statutory power to adopt regulations for sanitary food conditions, when another State statute allows outdoor

Page 775

food sale); Commonwealth v. Johnson Wholesale Perfume Co., 304 Mass. 452, 456-457 (1939) (regulation adding requirement that wholesaler sign guaranty to retailer that product not adulterated or misbranded, when unsigned guaranty by statute provides immunity to criminal prosecution, invalid). Further, he could not promulgate regulations which expand upon the statutory standards (as incorporating FTC and Federal court decisions) to include acts which are not, and have no potential to become, unfair or deceptive. His regulations will be subject to court challenge on the grounds that he has exceeded his statutory powers in defining "unfair" or "deceptive," or that a regulation is constitutionally invalid facially or as applied. See National Petroleum, supra at 693. They will be accorded the same deference as statutes upon review, however.

For all the foregoing reasons, we hold that the Legislature has, by G. L. c. 93A, Section 2 (c), delegated to the Attorney General the power to promulgate rules and regulations defining with specificity acts and practices which violate G. L. c. 93A, Section 2 (a). These rules and regulations have the same force of law as those of any "agency" as defined in G. L. c. 30A, Section 1 (2).

That the Attorney General has the power to promulgate regulations with the force of law is not conclusive on the question whether he has validly done so in the present case, a question to which we now turn.

4. Validity of the regulation. Purity argues that the Attorney General has exceeded his authority under Section 2 (c) because the regulation is inconsistent with FTC policy and with c. 93A, in that (a) the acts proscribed by the regulation are not in themselves unfair or deceptive; (b) FTC consent decrees have allowed pricing practices similar to that employed by Heartland, see 42 Fed. Reg. 23,843 et seq. (1977); and (c) the regulation was not adopted according to proper procedure.

a. Whether the regulation complies with c. 93A. i. Standard of review. The standard by which we are to determine whether the Attorney General has exceeded the authority

Page 776

delegated to him under G. L. c. 93A, Section 2 (c), is well established by Massachusetts precedent. We are "bound to test the regulations by the same standard which would apply to a statute. Thus, we must apply all rational presumptions in favor of the validity of the administrative action and not declare it void unless its provisions cannot by any reasonable construction be interpreted in harmony with the legislative mandate." Consolidated Cigar Corp., supra at 855. Grocery Mfrs. of America, Inc. v. Department of Pub. Health, 379 Mass. 70, 80 (1979). Greenleaf Fin. Co. v. Small Loans Regulatory Bd., 377 Mass. 282, 293-294 (1979). Colella, supra at 155-156. Druzik v. Board of Health of Haverhill, 324 Mass. 129, 138 (1949). A court may not substitute its judgment for that of the Legislature if the regulation comports with the power delegated, cf. Colella, supra at 156, and Purity has the burden of proving on the record "the absence of any conceivable ground upon which [the rule] may be upheld." Id. Purity may not meet its burden by arguing that the record does not affirmatively show facts which support the regulation. Colella, supra. Mile Road Corp. v. Boston, 345 Mass. 379, 382-383, appeal dismissed for want of a substantial Federal question, 373 U.S. 541 (1963).

The question before us is not whether the item price regulation is sound policy, but "whether the regulation bears a reasonable relation to the goal of consumer protection." Grocery Mfrs., supra at 85. That in turn depends on the purpose and meaning of c. 93A.

The over-all purpose of c. 93A is that of "providing proper disclosure of information and more equitable balance in the relationship of consumers to persons conducting business activities." Lowell Gas. Co. v. Attorney Gen., 377 Mass. 37, 51 (1979). Mechanics Nat'l Bank v. Killeen, 377 Mass. 100, 110 (1979). DeCotis, supra at 238.

ii. What constitutes "unfair" and "deceptive." This court has declined to adopt a static definition of either "unfair" or "deceptive." "It would doubtless be helpful if there were a clear definition of conduct which may constitute a

Page 777

violation of c. 93A. Such a definition would assist litigants in identifying those cases which have only the normal incentives for settlement as distinguished from those which truly implicate the incentives under c. 93A." Whitinsville Plaza, Inc. v. Kotseas, 378 Mass. 85, 100 (1979). We concluded in Whitinsville that there had not yet been "a sufficient amount of litigation from which to develop definitions." Id. See DeCotis, supra at 241-242. The following definitions offer some guidance, however.

The FTC has promulgated a general definition of what is "unfair" though not necessarily deceptive: "(1) whether the practice, without necessarily having been previously considered unlawful, offends public policy as it has been established by statutes, the common law, or otherwise -- whether, in other words, it is within at least the penumbra of some common-law, statutory, or other established concept of unfairness; (2) whether it is immoral, unethical, oppressive, or unscrupulous; (3) whether it causes substantial injury to consumers (or competitors or other businessmen)." 29 Fed. Reg. 8355 (1964). A practice may be "deceptive" if it "could reasonably be found to have caused a person to act differently from the way he otherwise would have acted." Lowell Gas Co., supra at 51. York v. Sullivan, supra at 162. [Note 17]

Page 778

Undoubtedly if a definition could be developed from the cases, to provide a "bright line" against which businesses might judge their conduct, it would prove helpful both to avoid litigation and to facilitate the settlement process. The rules and regulations of the Attorney General will not necessarily exhaust the field of unfair or deceptive acts potentially violative of c. 93A. They will, however, provide notice to persons engaged in trade or commerce of acts for which injunctions and penalties may be sought under c. 93A, thus mitigating possible vagueness of a statute intentionally left open-ended to encompass new acts. See DeCotis, supra at 242.

iii. Whether the UPC system is "unfair" or "deceptive." While it does not appear that the UPC system, if it functions effectively, is unfair or deceptive per se, the Attorney General argues that the system does not entirely lack the potential for both unfairness and deception, even caused by good faith error. His argument is that price changes may be made at the computer terminal and stores may fail to change signs until hours or even days later, resulting in undisclosed

Page 779

overcharges in clear violation of c. 93A, that signs may become obscured or incorrectly placed, or items may be placed on incorrect shelves, and that time-conscious consumers may well forgo marking each item with pencils provided therefor. [Note 18]

Regulation in the consumer field may be preventive. See Floersheim, supra at 955. We cannot say that the Attorney General has acted unreasonably in attempting to prevent potentially unfair acts or practices before they pose a threat to consumers. He has acted within his statutory authority, and the method he has chosen is reasonable. [Note 19] We are aware of the fact that if Purity has to operate under a dual system (UPC and item marking, the latter being mandated by the regulation), some of the additional cost of item marking may be reflected in increased prices to the consumer. This extra cost of the dual system does not support Purity's claim of unreasonableness. Cf. DeCotis, supra at 241 n.5. It is a factor which may be considered by the administrative rule-making body, but there is no requirement that such body choose the least restrictive alternative. Consolidated Cigar Corp., supra at 853, and cases cited. Purity has failed to meet its burden of demonstrating that the regulation lacks any rational relationship to the goals of c. 93A.

b. Consistency with FTC policy. In support of its contention that the regulation is inconsistent with FTC decisions, Purity points to cases in which consent decrees have

Page 780

allowed the use of UPC systems. The decrees required item pricing of goods which are advertised but allowed the advertised price to be "clearly and conspicuously posted at the point of display" in the case of "stores equipped with devices which `read' an identification code marked on the packaging of items, and which transmit the information to a computer ...." See 42 Fed. Reg. 23,843-23,847,23,849-23,851 (1977).

We note first that there is no provision in the FTC Act and no FTC regulation expressly precluding States from requiring item pricing. Nor is there an FTC regulation requiring item pricing. States are not forbidden, however, from adopting rules more restrictive than those of the FTC. See generally Mobil Oil Corp. v. Attorney Gen., 361 Mass. 401 (1972). Mobil Oil was a preemption case, and did not involve the proscription of c. 93A, Section 2 (c), that the Attorney General's rules may not be inconsistent with FTC decisions. Mobil Oil held, however, that a Federal regulatory scheme for lotteries did not preempt a State statute totally prohibiting the same type of lottery. A similar rationale applies here, especially in light of the fact that the UPC pricing system has the potential for unfairness and deception. Furthermore, the entry of such consent decrees in past cases would not prevent the FTC from enacting a rule requiring item pricing should it find that electronic scanner systems work unfairness or deception at some future time. [Note 20]

c. Promulgation procedure. Purity alleges that the regulation was not adopted according to proper procedures. As we stated above, the office of the Attorney General is an "agency" within the meaning of G. L. c. 30A, Section 1 (2), for it is a "department ... of the state government ... authorized by law to make regulations ...."

Page 781

Cf. Bay State Horse Racing & Breeding Ass'n v. State Racing Comm'n, 342 Mass. 694, 700-701 (1961). Its regulations meet the definition in G. L. c. 30A, Section 1 (5) ("adopted by an agency to implement or interpret the law enforced or administered by it"). Therefore the procedural requirements of c. 30A apply to the regulation in question.

The parties have stipulated that a public hearing was held before the adoption of the regulation, and that notice was given "in accordance with the standards contained in Chapter 30A." Because he held a public hearing, the Attorney General complied with the requirements of Section 2 of c. 30A, which are more stringent than those of Section 3. Section 2 requirements include publication, filing of the notice with the State Secretary, and delivering or mailing notice to persons or groups "filing written request for notice of agency rule making proceedings." Purity does not allege that it did not receive notice of the hearing or an opportunity to present its views. It alleges only that notice was not widely publicized, and that the Attorney General offered no statement of his reasons for adopting the regulation.

There is no requirement that the Attorney General include a statement of facts supporting the regulation. Grocery Mfrs., supra at 79. Cambridge Elec. Light Co., supra at 490-491. Purity contends that the Attorney General must meet the procedural requirements imposed on the FTC, one of which is a statement of the basis for adoption. See 15 U.S.C. Section 57a. This argument is without foundation. General Laws c. 93A, Section 2 (b), directs courts to consider the FTC Act only in regard to definitions of "unfair" and "deceptive"; [Note 21] nowhere does c. 93A incorporate

Page 782

FTC procedure. The State Administrative Procedure Act (c. 30A) applies, and the Attorney General has met the procedural requirements of that Act. See generally, Grocery Mfrs., supra at 79. The record discloses no irregularity in procedure which would call into question the validity of the regulation.

We note that the parties have agreed that the Attorney General has offered to hold a public hearing on the UPC. This would provide a forum to examine whether it would be in the public interest to exempt UPC systems from the regulation. Purity could have availed itself of this opportunity it had but did not do so.

5. Purity's compliance. Purity contends that in any event it complies with the regulation because it affixes prices to shelves or cartons. The regulation requires sellers to affix prices "to any goods." There is nothing in the rule or in the record before us to indicate that the phrase "to any goods" was intended to include the shelves on which the goods were stored or displayed or the cartons in which they were contained. In the absence of clear error, the interpretation an administrative body gives to its own rule is entitled to deference. Finkelstein v. Board of Registration in Optometry, 370 Mass. 476, 478 (1976). FTC v. Anderson, 442 F. Supp. 1118, 1127 (D.D.C. 1977). Cf. Cleary v. Cardullo's Inc., supra at 342-345. A court will overturn such an agency interpretation only if it is "arbitrary, unreasonable, or inconsistent with the plain terms of the rule itself." Finkelstein, supra. A general term of a statute may not be construed differently from its plain meaning, especially in the absence of any evidence of legislative or administrative intent so to construe it, Mile Road Corp., supra, and we may apply that same principle to the regulation. Therefore, the word "goods" must be taken to mean the individual articles for sale, as the Attorney General has construed it. Purity is not in compliance with the regulation.

6. Equal protection. Purity's equal protection argument is essentially that by the enforcement of the regulation

Page 783

against a supermarket, the Attorney General is treating Purity unequally with no rational basis for doing so. As an example, Purity says this action would result in mandatory price affixation to "fish in a supermarket, but not to fish in a fish store."

Such a selective enforcement argument lacks substance. First, there is no such distinction on the face of the regulation; it applies to "any person subject to this act [c. 93A]." Second, the Attorney General is not required to enforce the regulation against all potential violators simultaneously; he may proceed in an orderly fashion. See Consolidated Cigar Corp., supra at 854; Mobil Oil Corp., supra at 417; Ger-Ro-Mar, Inc. v. FTC, 518 F.2d 33, 35 (2d Cir. 1975). Furthermore, it is conceivable that the Attorney General could properly decide to treat supermarkets differently from small fish stores. A conceivable rational basis for such treatment could be that the former are generally self-service, whereas the latter may involve service by a salesperson pursuant to a customer request for a certain quantity of fish from a tray containing a price. The important factor is that the consumer be aware at the time of decision to purchase how much he will pay for the item.

7. Due process. Purity's due process argument is that the regulation "arbitrarily interferes with Purity's right to conduct its business." Purity maintains that the means chosen to effectuate the purposes of the regulation are arbitrary and unreasonable. It appends to its brief a consent decree reached by the Attorney General and First National Stores, Inc. This agreement allows First National to omit affixing prices to "non-prepackaged food" such as loose fruits and vegetables and delicatessen items, individual packages of cigarettes, and "small consumer commodities" weighing less than two ounces and costing less than thirty cents, such as packages of chewing gum.

Purity makes no showing that such exceptions to the regulation are not being allowed as to its stores. Rather it asserts that the allowance of such exceptions illustrates arbitrary and irrational enforcement. We disagree. It is true

that the regulation carried to absurd limits potentially allows the Attorney General to require price affixation to each piece of loose fruit. Exemption of such items, as long as the exemptions are applied to all sellers of similar items, is a reasonable exercise of the Attorney General's discretionary enforcement power as granted by G. L. c. 93A, Sections 4-8. There is no due process violation.

8. The cases are remanded to the Superior Court, where judgments shall be entered as follows. In case number 77-3436, that the injunction was validly issued and shall continue in full force and effect. In case number 77-3530, that the Attorney General had the statutory authority to adopt Regulation XII (A) (1), that he complied with the procedural requirements of law in adopting it, and that the regulation may constitutionally be applied to Purity.

So ordered.
