There's a new blog out there called New Private Law. Its editors apparently define "private law" as including "the areas of torts, property, contracts, intellectual property, commercial law, wills & trusts, and remedies."
I'm afraid I have to agree with Matt Bodie (which does't happen every day), who observed:
... what’s the source for your definition of private law? I understand the exclusion of employment law (though I would disagree substantively), but what about corporate and securities law? I thought those were pretty firmly ensconced as private law.
