About The Rule of Five: Making Climate History at the Supreme Court
“When the Supreme Court announced its ruling in Massachusetts v. EPA, the decision was immediately hailed as a landmark. But this was the farthest thing from anyone’s mind when Joe Mendelson, an idealistic lawyer working on a shoestring budget for an environmental organization no one had heard of, decided to press his quixotic case.
In October 1999, Mendelson hand-delivered a petition to the Environmental Protection Agency asking it to restrict greenhouse gas emissions from new cars. The Clean Air Act had authorized the EPA to regulate “any air pollutant” that could reasonably be anticipated to endanger public health. But could something as ordinary as carbon dioxide really be considered a harmful pollutant? And even if the EPA had the authority to regulate emissions, could it be forced to do so?
Environmentalists urged Mendelson to stand down. Thinking of his young daughters and determined to fight climate change, he pressed on—and brought Sierra Club, Greenpeace, NRDC, and twelve state attorneys general led by Massachusetts to his side. This unlikely group—they called themselves the Carbon Dioxide Warriors—challenged the Bush administration and took the EPA to court.
The Rule of Five tells the story of their unexpected triumph. We see how accidents, infighting, luck, superb lawyering, and the arcane practices of the Supreme Court collided to produce a legal miracle. An acclaimed advocate, Richard Lazarus reveals the personal dynamics of the justices and dramatizes the workings of the Court. The final ruling, by a razor-thin 5–4 margin, made possible important environmental safeguards which the Trump administration now seeks to unravel.” — Harvard University Press

More About The Rule of Five: Making Climate History at the Supreme Court
“The Rule of Five is the gripping story of the most important environmental law case ever decided by the US Supreme Court. Richard Lazarus’s compelling narrative is enlivened by colorful characters, a canny dissection of courtroom strategy, and a case where the stakes are, literally, as big as the world.” — Scott Turow, author of Presumed Innocent
“In the tradition of A Civil Action, this book makes a compelling story of the court fight that paved the way for regulating the emissions now overheating the planet. It offers a poignant reminder of how far we’ve come—and how far we still must go.” — Bill McKibben, author of The End of Nature
“The Rule of Five is the definitive inside account of one of the key court decisions of our time. It’s also more than that. Richard Lazarus makes vivid the culture of the Supreme Court and the sheer unlikeliness of history. There’s no better book if you want to understand the past, present, and future of environmental litigation.” — Elizabeth Kolbert, author of The Sixth Extinction
“The Rule of Five is a compelling read on a critical and timely topic. It mixes storytelling with a soup-to-nuts view of a pivotal case contested across all three branches of government. The focus on the six Carbon Dioxide Warriors adds to the richness of the story and demonstrates how the often-abstract nature of the law can actually be very personality-driven. Lazarus also does an excellent job illuminating the inner workings of the Supreme Court and of the second most important court in the land—the US Court of Appeals for the District of Columbia Circuit.” — Dan Reicher, former US Assistant Secretary of Energy
“As legal drama, The Rule of Five is a tour de force. It offers a look into the inner workings of the nation’s highest court, and a history of its most important environmental decision. With impressive research, including interviews with the key players, and succinct explanations of relevant law and Supreme Court practice, the narrative makes the story accessible to anyone interested in this case, the Court, and the future of the planet.” — Jonathan Z. Cannon, author of Environment in the Balance: The Green Movement and the Supreme Court
