Section 263 of the Mississippi Constitution used to prohibit interracial marriage. While this was declared unconstitutional by Loving v. Virginia in 1967, the voters and legislature of Mississippi finally got around to repealing it in 1987.
And what went into that vacancy? Section 263A of the constitution now sits right behind the space 263 used to occupy. 263A declares marriages between people of the same gender void and unenforceable. And, by way of another little joke from the folks at Thomson West, under the section Cross References after 263A, we get referred to the Due Process and Equal Protection clauses of the United States and Mississippi constitution (well, the former only for Mississippi) and to the establishment and free exercise of religion clauses of both. Just in case you might wonder where to begin in finding other constitutional provisions that might be inconsistent.
