That notion that the concept of a "penumbra" of protection was a fiction created in Griswald and later applied in Roe v. Wade to haunt us ever since is, itself, a fiction. Even Robert Bork, strict constructionist extraordinaire, agreed in The Tempting of America, that courts often create a buffer zone by prohibiting a government from doing something not itself forbidden but likely to lead to the invasion of a right that is specified in the constitution. He didn't use the term "penumbra," and he certainly did not agree with the reasoning in Griswold, but he recognized the basic concept. There are bedrock constitutional law principles founded on principles not stated anywhere in the text of the constitution but derived from an overall understanding of the principles it is intended to protect. Conservative and liberal courts both use the concept of penumbras, even when they are not using that word to describe it. But the word serves as a convenient and oversimplified way to describe a decision one does not like as an example of judicial overreaching.
