That's one of the court's jobs, after all, to evaluate complex or difficult situations and laws where it is not immediately clear what the law says. It reminds me of especially tortured and opaque code. You can't see on the surface that foo=bar, but after a long and arduous process of evaluation you discover- lo and behold- foo=bar all along. Or even more difficult, you discover that foo=1 implies bar=2.
