The 4th appellate district division one is comprised of 10 justices. Four are considered conservative, one moderate, two liberal and three we don't really know, which means they have not issued any "activist" rulings of any kind.
That's the district you cited. You are not understanding the ruling issued. It had nothing to do with FB. It had to do with whether Jessica's law in CA was too restrictive as some sex offenders claim there is no place they can live due to the law and the law does not discriminate as to degrees of sex offenders. So a 25 year old who is designated a sex offender due to having sex with a minor, is subject to this law.
The appellate court found the law was too restrictive due to its failure to discriminate between types of sex offenders. From your link: BTW, I am a liberal. I know almost no liberals who believe sex offenders or abusers of children should be given a break. I voted for Jessica's law. I take offense to the term "wacky liberal".
