Since the citizens' elected representatives decided the matter as per the will of the citizens - utilizing their republican form of government, hasn't the CA Supreme Court invalidated their republican government?
Correct. What California has now is a Socialist form of Government where the citizens and non-citizens are equal without any representation. The only difference is the citizens pay taxes and the non-citizens receive illegal Government payments.
All the judges did in this case was say The law enacted by the state legislature did not follow the state Constitution. If the elected representatives wanted to ban gay marriage, they have to change the state constitution.
This is not judicial activism. The judges acted in a strict accordance to the laws.
Look at it this way, in Washington DC they had the most restrictive handgun ban in the nation, the elected representatives liked it, the mayor liked it, the vast majority of people liked it, the cops liked it, but that law violated the US Constitution, so the judges threw the law out. Now not one freeper would dare call those Judges Activist.
But what's the difference between the two? Oh yeah we like guns more than gay marriage.
