(b) Section 425.16 does not apply to any action brought solely in the public interest or on behalf of the general public if all of the following conditions exist:

1. (1) The plaintiff does not seek any relief greater than or different from the relief sought for the general public or a class of which the plaintiff is a member. A claim for attorney’s fees, costs, or penalties does not constitute greater or different relief for purposes of this subdivision.
2. (2) The action, if successful, would enforce an important right affecting the public interest, and would confer a significant benefit, whether pecuniary or nonpecuniary, on the general public or a large class of persons.
3. (3) Private enforcement is necessary and places a disproportionate financial burden on the plaintiff in relation to the plaintiff’s stake in the matter.

(c) Section 425.16 does not apply to any cause of action brought against a person primarily engaged in the business of selling or leasing goods or services, including, but not limited to, insurance, securities, or financial instruments, arising from any statement or conduct by that person if both of the following conditions exist:

1. (1) The statement or conduct consists of representations of fact about that person’s or a business competitor’s business operations, goods, or services, that is made for the purpose of obtaining approval for, promoting, or securing sales or leases of, or commercial transactions in, the person’s goods or services, or the statement or conduct was made in the course of delivering the person’s goods or services.
2. (2) The intended audience is an actual or potential buyer or customer, or a person likely to repeat the statement to, or otherwise influence, an actual or potential buyer or customer, or the statement or conduct arose out of or within the context of a regulatory approval process, proceeding, or investigation, except where the statement or conduct was made by a telephone corporation in the course of a proceeding before the California Public Utilities Commission and is the subject of a lawsuit brought by a competitor, notwithstanding that the conduct or statement concerns an important public issue.

(d) Subdivisions (b) and (c) do not apply to any of the following:

1. (1) Any person enumerated in subdivision (b) of Section 2 of Article I of the California Constitution or Section 1070 of the Evidence Code, or any person engaged in the dissemination of ideas or expression in any book or academic journal, while engaged in the gathering, receiving, or processing of information for communication to the public.
2. (2) Any action against any person or entity based upon the creation, dissemination, exhibition, advertisement, or other similar promotion of any dramatic, literary, musical, political, or artistic work, including, but not limited to, a motion picture or television program, or an article published in a newspaper or magazine of general circulation.
3. (3) Any nonprofit organization that receives more than 50 percent of its annual revenues from federal, state, or local government grants, awards, programs, or reimbursements for services rendered.
