I don't think that's what Kavanaugh was doing. If you're thinking of taking those 83 into account in your ruling, but you aren't exactly sure that they're solid, you ask a question: Hey, Google, explain to me why these are important. It doesn't mean that he's dismissing them. It is at least as likely that he's considering relying on them, and wants to have a solid justification for doing so. (Remember, Oracle also claimed that the world would end if the court decided for Google.)
