The Court's reliance upon stare decisis can best be described as contrived. It insists upon the necessity of adhering not to all of Roe, but only to what it calls the 'central holding.' It seems to me that stare decisis ought to be applied even to the doctrine of stare decisis, and I confess never to have heard of this new, keep-what-you-want-and-throw-away-the-rest version.
