Voted by the legislature or ordered by the governor; it would depend on the specifics of the state constitution. I don't know SC law in that much detail.
Was it made into law? if so, it's not quite that simple to stir it up.
Oh, sure it is. "Made into law" does not end the argument. If you will, allow me to offer some word pairs; Scott/Sanford. Plessy/Ferguson. Brown/Board. Lemon.Kurtzman. Roe/Wade.
Not only is it fairly easy to fight the law, but for Americans, it's habitual. It;s part of our national DNA. Fighting the law is how we came to exist, and fighting unjust laws is how we survive, And thrive.
