"MR. STEWART: Casey gave one paragraph to the workability of Roe. It then adopted the undue burden standard, which is perhaps the most unworkable standard in American law. It gave about three paragraphs, if memory serves, to reliance, which doesn't account for the last 30 years and the changes that have occurred since Casey. It did -- it -- it gave a brief factual view to things that have changed since Roe. Those, of course, are not going to take account of the last 30 years of advancements in medicine, science, all of those things."
