This ruling was issued by California's State Supreme Court. The Scouts think things may be different when the appeal to SCOTUS, and I tend to agree with them.
This was the appeal to SCOTUS, which refused to hear the case.
"The action let stand a unanimous California Supreme Court ruling".
Sorry, but this story is about the SCOTUS refusing to hear the case, letting the California Supreme Court decision stand. The California court already ruled, unanimously, and the SCOTUS won't review the decision.
