You have absolutely no clue what you're talking about. Even if we're playing by the book, the Supreme Court can choose not to grant cert because they believe a compelling circuit split hasn't yet emerged, stare decisis, they don't believe the controversy is ripe, they think it's a matter for someone else like the legislature, they don't have space on the docket, etc. Not granting cert is absolutely not an endorsement of legal interpretation by a lower court. Beyond that, idea that justices wouldn't, even subconsciously, use the power to choose their own docket to favor their own policy preferences is just naive.
