The justices of the Supreme Court are highly literate -- as well as literal people. Their livelihoods and judgements rely on the meaning of words. Their opinions draw from history, precedent, Latin, analogy, similarity and they have to communicate it through words, not code. In terms that can convey generally understood meaning and principles without having to rehash entire books to ensure thorough understanding. Opinions have included Shakespeare, poetry, wit, sarcasm.
