I am unclear as to what has actually been decided. If states have a prohibition against gay marriage, can the Feds rule those laws null and void once they are challenged in the courts?
The problem the supporters of prop 8 had was that their own elected government officials ( governor, sec of state etc.) refused to defend the law that it’s citizens voted for...and the SCOTUS decided that the individual citizens did not have standing in federal court to argue for a bill that their own state government did not support
in other words the law they voted for was doomed by the people they voted into office
whether the supreme court would overturn a prop 8 like law that WAS supported by the state it was passed in and that government argued the case before the court is a different question... that I’m sure will now arrive at the SCOTUS sooner rather than later
