I don't think the California Supreme Court is some "state court" where the justices are looking to "make a 1 o'clock tee time," although I could be wrong. Please enlighten me. I also don't think they are waiting to be "spoon fed" some answer by the state bar. You're talking about justices who likely relish having the final say as to what California law is. The idea that they're inclined to being spoon fed their decisions flies in the face of what it means to be on any state supreme court. Maybe your conclusion is right, but I don't follow the argument at all.
They're all pulled from the same bunch, I don't see how it is wrong. Once you've been in practice for a while, you begin to see patterns within the court system. One of those patterns is that the vast majority of judges are willing to take the easiest route available. The easier you make it for them, the more you spoon feed, the more likely they side with what you want. They're especially prone to align with an opinion that comes from a prestigious organization like the Bar in my opinion--prestige and power drives the industry, starts in law school, and it doesn't just fall apart afterwords. Just the way it goes my friend, it's human nature.
