I know where you're going with this, and the idea of putting a limit on the power of the SCOTUS and returning the power that it has usurped back to the people and the states, rather than defining marriage, is certainly appealing.
The problem with limits on appeals on the matter of sex is that the argument will be made that it will prevent review of discrimination lawsuits, etc. That may be a great idea, it's debatale, but that fear would defeat the Amendment as you've worded it.
