Justice Glenn Murdock wrote a document that could get rid of marriages all together.
Think Progress reports:
Justice Murdock’s opinion is attached to a brief order from the state supreme court as a whole declining to offer further guidance to Alabama probate judges regarding whether they must comply with a federal court order holding that same-sex couples are entitled to the same marriage rights as straight couples. In a brief opinion concurring in that order, Murdock hints that, if this federal court order is permitted to stand, then his own court should strike down all marriages within the state of Alabama.
Murdock suggests that, had the state legislature known that its decision to exclude gay couples from the right to marry was unconstitutional, it might have preferred not to permit anyone to be married in the state of Alabama. This potential preference for no marriages over equality matters, according to Justice Murdock, because of a prior state supreme court decision holding that, when part of a state law is struck down, the law may be declared “wholly void” if “the invalid portion is so important to the general plan and operation of the law in its entirety as reasonably to lead to the conclusion that it would not have been adopted if the legislature had perceived the invalidity of the part so held to be unconstitutional.”
