Here is a link to a very good essay by Adam MacLeod critiquing the recent decision of the Kansas Supreme Court that found a natural right to abortion. Here is a paragraph from the essay–
“This essay considers the humorous incompetence of the opinion, not for amusement but to learn an important lesson. American constitutions contain terms of art taken from common law, including terms that refer to peculiarly Anglo-American doctrines of natural rights. If we want judges to understand and apply those terms correctly, then we must recover that tradition. Otherwise, judges will make things up, as they did in Kansas. “
