I know it affects the single District, but if appealed and upheld as far as the Supreme Court, it will be the law of the land.
Even as a District Court ruling it becomes precedent for other courts.
I suspect you will see the Gubernator NOT appealing this case to the 9th ~ and it'll just die.
What you will need to do is run another referendum, and keep on doing that until you have some trustworthy individuals in your state government's leadership positions, and several federal judges out there die ~ or retire (although it is preferable they simply pass on to the other side ~ where Satan awaits them ~ else they continue to serve as judges on a part time basis and can continue to create mischief).
