The California State Bar Act imposes a duty on attorneys to "support the Constitution and laws of the United States and of this state".  Cal. Bus. & Prof. Code § 6068(a).  Many California legislators are members of the California State Bar, including former state senator Hannah-Beth Jackson.  Senator Jackson had been a member of the California bar for more than four decades when she introduced SB 826, a bill mandating minimum number of directors on boards of publicly traded companies.  Even supporters of the law were aware that it was likely to be unconstitutional.  As Governor Jerry Brown noted in his signing message: 

There have been numerous objections to this bill and serious legal concerns have been raised. I don't minimize the potential flaws that indeed may prove fatal to its ultimate implementation.

Thus, it should have been a surprise to no one when Los Angeles Superior Court Judge Maureen Duffy-Lewis after a trial held that SB 826 violated the Equal Protection clause of the California Constitution (A person may not be . . . denied equal protection of the law").  Crest v. Padilla, L.A. Super. Ct. Case No. 19STCV27561 (March 13, 2022).  See The Verdict Is In On California's Female Director Quota Law.

By writing and supporting a law that was widely acknowledged (even by the Governor who signed it) to be constitutionally suspect, did Senator Jackson fail to support the California Constitution?  If the answer is no, are there any circumstances in which a lawyer-legislator could be disciplined for writing or voting for unconstitutional legislation?  If the answer is yes, could the State Bar also discipline a lawyer who testified or gave a speech in support of SB 826?
