By discussing items of Association business in e-mails (e.g., whether to approve appellants’ landscaping plans and whether to fine another homeowner), the directors did nothing contrary to the purpose of the OMA, because they took no action on those items in the e-mails. Although the OMA prohibits the board from acting on items of Association business outside a board meeting (§ 4910, subd. (a)), it does not prohibit the board from discussing the items outside a meeting. Had the Legislature intended to prohibit such discussions, it knew how to do so. In the Ralph M. Brown Act (Gov. Code, § 54950 et seq.), an open meeting law that governs public agencies and the provisions of which “parallel” those of the OMA (Damon, supra, 85 Cal.App.4th at p. 475, 102 Cal.Rptr.2d 205), the Legislature provided: “A majority of the members of a legislative body shall not, outside a meeting authorized by this chapter, use a series of communications of any kind, directly or through intermediaries, to discuss, deliberate, or take action on any item of business that is within the subject matter jurisdiction of the legislative body” (Gov. Code, § 54952.2, subd. (b)(1)). Interpreting section 4090, subdivision (a) to include the e-mail exchanges at issue in this case, as appellants would have us do, would effectively add to the OMA a similar provision prohibiting directors from discussing items of association business except at a board meeting. We refuse to adopt an interpretation of a statute that would require insertion of language the Legislature knew how to include but did not include. (Emphasis added.)
