In the state of Washington, the legislature just passed a capital-gains tax, which the Governor is expected to sign. Washington also has a voter referendum process. But according to this story, the legislation includes a provision that prevents a referendum to challenge this particular measure. In other words, the legislature has withdrawn the direct-democracy process for this specific issue.
I believe that in some states with direct democracy, there is general legislation that defines in advance certain subjects for which direct democracy (1) is required, see Gordon v. Lance, 403 U.S. 1 (1971) and (2) is not permitted. But I’m wondering if there are other examples of specific legislation that includes provisions that withdraw an otherwise available direct-democracy option for that specific issue.
