Of course, there are. But are there big ideas that go some place?
This question is prompted by the death of Jeffrey O'Connell, who with Robert Keeton "invented" no-fault auto insurance. Other examples of big ideas in law that actually had consequences are Charles Reich's article THE NEW PROPERTY and Catherine McKinnon's work on sexual harrassment.
The recognition of a constitutional privacy right is another big idea but I don't know to whom in particular we should give credit. Probably many.
But has there ever been a big idea, or even a medium idea, that "rocked" the world of lawyer regulation? That made more than small, incremental changes? Or is this a subject that will only develop inch by inch? And if so, is that something we should regret?
