Presenting: Outside/In

It's one of the most important Supreme Court cases you may never have heard of: Massachusetts v. Environmental Protection Agency. The ruling held that the U.S. government could regulate greenhouse gases. Today we’re sharing the wild backstory of this critical Supreme Court case, from a podcast we love,“Outside/In,” from New Hampshire Public Radio. If you don’t believe a legal case in all its intimate details can be riveting, take a listen. And be sure to check out all the other great episodes from Outside/In.
