[This section’s article (ARTICLE 5. Inclusion of Medi-Cal Managed Care Plans in Sales Tax [6174. - 6189.]) states its own repeal: “6189. … As of January 1, 2017, this article is repealed.” Section 6187 repeals the article sooner only “if it is delayed based upon a challenge under federal law”; no source shows such a delay, and the 2016 managed care organization tax was enacted to replace “the funds generated by the tax imposed pursuant to Article 5 (commencing with Section 6174)” (Stats. 2016, 2nd Ex. Sess., Ch. 2).]
