In a nutshell - Jerry Brown and a single judge have more power than the population of California. Citizens have "no legal standing" to appeal the judges ruling. That's what this decision means. I think this is far reaching and not good.
Your “nutshell” is pretty spot on.
There is a tenant in judicial review that if you can avoid making a decision on Constitutional grounds, and can find other dispositive grounds, that is how you decide the case. That’s what happened here.
The worst part is, now that it is done, the case WILL be back (Full Faith & Credit probably) and I would bet pretty much anything that SCOTUS approves gay marriage nationwide.
Imagine if this was the ruling on Brown VS Topeka?
I agree, I most concerned with the fact that if a State’s AG and governor do not sign on to what the people wanted that it’s impossible to overturn a federal ruling on the case. That seems awfully heavy handed for the people who say they want to protect the people from oppressive governments.
