On March 5, the California Libertarian Party state committee resolved to oppose California SB 27. It requires candidates in presidential primaries to reveal the last five years of their income tax forms, if they were required to file such forms. The California Libertarian Party is directly affected by this law, because the state has been providing a presidential primary for the party starting in 1980.

SB 27 has a hearing in the Senate Elections Committee on March 19. If it is signed into law, it takes effect immediately. A similar bill was vetoed by Governor Jerry Brown a few years ago, but Brown is no longer Governor.
