Opinion
Does California’s Structural Pest Control Act (Bus. & Prоf. Code, §§ 8500-8677) apply to door-to-door solicitors of free structural pest control inspections, and, if it does, is such application constitutional? The trial court answered both questions in the affirmative and concluded that the act covers the solicitations being carried on by plaintiffs, that .such coverage is constitutionаl, and that plaintiffs are not entitled to conduct door-to-door solicitations for free pest control inspections without securing a license under the act.
Appellants argue: (1) the statute does not cover their activities, (2) but if it does, the statute bears no reasonable relationship to the public interest and is therefоre unconstitutional.
I
The statute defines structural pest control to include “soliciting . . . of an inspection or inspections for the purpose of identifying ... infestations . . (§ 8505.) Article 3 of the Structural Pest Control Act makes it unlawful for any unlicensed person to engage in the business of structural pest control. (§ 8550.)
A qualified person may obtain a license as a structural pest control operator or as a structural pest control field representative. An applicant for either category of license must possess good character (§ 8568); demonstrate, by examination, knowledge of pertinent laws, of the dangerous chemicals used in pest control, and of thе theory and practice of pest control (§§ 8565, 8566); and establish the requisite training and experience of two years for operators and six months for field representatives. (§§ 8562, 8564.)
There is no general exemption in the act for all employees of a licensed operator. But the Legislature has authorized unlicensed employees to perform acts under specified conditions which would otherwise require a license. Section 8506 permits an operator to use unlicensed individuals “on service contracts already established” but such individuals, i.e., crewmen, must work on pest control jobs under the supervision of an operator or field representative. (§ 8512.) Futhermore, only after an inspection by a *220 licensed operator or field representative may an unlicensed employee submit bids or sign contracts on behalf of a licensed corporation, partnership, or individual. (§ 8515.)
It is significant that the legislative definitions of structural pest control operator and structural рest control field representative permit the licensee to “secure structural pest control work.” (§§ 8506, 8507.) The term “secure” in sections 8506 and 8507 is used in addition to inspecting, bidding, or contracting in both sections and must mean the direct contacts with home owners prior to inspecting and bidding. Thus, by denying a general exemption for all employees, by granting authority to licensed individuals to “secure work,” and by not granting authority to unlicensed employees to solicit or otherwise secure work, the clear implication, under the rule expressio unius est exclusio alterius, is that unlicensed employees may not solicit or otherwise secure structural pest control work.
While the primary purpose of prohibiting soliсitation may have been to prevent persons who represent non-licensees from doing anything that would bring pest control work to their principals, the Legislature may well have concluded from past selling practices in the structural pest control field that to protect the public only persons of established character and knowledge should be permitted to solicit or otherwise attempt to secure pest control work on behalf of licensed operators.
It is plain to us that the act covers solicitations carried on in the manner described in the complaint by appellants. Whether such coverage is desirable or undesirаble involves arguments on policy which must be addressed to the Legislature.
II
Appellants’ second contention, that of unconstitutionality, involves the general question of regulation of door-to-door solicitation. On this point we find ourselves in complete agreement with the arguments presented in respondent’s brief, and we hereby adоpt them as the court’s opinion on constitutionality:
Appellants argue it is an invalid exercise of the police power to require a person who limits his activities to door-to-door solicitation of free inspections by his employer to be licensed, either as a structural pest control operator or as a field representative. Appellants further assert that, as applied, the act violated the Fourteenth Amendment guarantees of due process, equal protection, and free speech.
All presumptions favor the constitutionality of a statute enacted by the Legislature; all doubts are resolved in favor of and not against the validity of the statute. Before an act of a coordinate branch of the government can be declared invalid for the reason that it is in conflict with the Constitution, such conflict must be clear, positive, and unquestionable.

Thus, “. . . judicial examination of a statute under economic due process attack is completed when any fact or facts appear which the legislature might rationally have accepted as the basis for a finding of public interest. ...

The current doctrine of judicial review of the reasonableness of regulatory legislation is that judiсial examination of a statute under economic due process attack is completed when any fact or facts appear, or may be hypothesized, which the Legislature might rationally have accepted as the basis for a finding of public interest.

v.
Board of Medical Examiners,
There are many rationally acceptable hypotheses for the requirement that a licensed operator perform his own direct contact with owners or hire a licensed field representative to perform that activity. The Legislature may have believed that direct person-to-person contact between a repre *224 sentative of the licensee and the home owner was bound to engender a discussion of the technical aspects of structural pest control; that unlicensed solicitors would tend to exceed their instructiоns in order to bring in customers; that companies might employ solicitors who are not well instructed; that solicitors might tend to make misleading statements and offer technical advice; and that unlicensed solicitors might not meet the character requirements imposed upon operators and field representatives. (§ 8568.) These furnish sufficient justifiсation for the legislative action.
Appellants also contend that owners of structural pest control operations have been unreasonably discriminated against by the Legislature and thereby denied equal protection of the laws. We are unable to find such discrimination. Unlicensed employees in a real estate office cannot solicit listings. (§§ 10130-10132.) Nor can unlicensed employees of a cemetery broker solicit the sale or purchase of cemetery property. (§ 9676, 9677.) Nor can attorneys abdicate their powers and privileges to unlicensed representatives. (Cf.

Appellants’ final constitutional argument is that the Structural Pest Control Act, as applied, violates freedom of speech. The state
