In the Supreme Court’s Own Words: First Principles for Checking Presidential Power and Preserving the Republic explores how the U.S. Supreme Court has served as a constitutional check on executive overreach from the Founding Era to the present.

Spanning decisions from 1803 to 2024, the book traces how the Court has articulated – and repeatedly affirmed – bedrock principles that define the lawful boundaries of presidential power.

Distinctive in approach, the book weaves together the Supreme Court’s own words with vivid, contemporary hypotheticals that bring constitutional principles to life.

Designed to be both historically grounded and civically useful, it invites readers to engage directly with the language of the Court while offering clear, plain-language guidance through its more complex rulings.

Written by a veteran litigator and legal educator,,In the Supreme Court’s Own Words provides an accessible yet rigorous account of how the Constitution operates under stress – offering a timely and necessary reflection on the role of law in checking presidential power and preserving the American Republic.

What Readers Are Saying

  • “This is a book that contributes to the current public debate about the extent of Presidential powers. It is a fairly comprehensive analysis of how SCOTUS has ruled on issues involving Executive powers. It is well written and appropriate for the general public.”

  • “Beautifully written, logically explained, and very, very interesting. Whether you're a policy work, a legal scholar, or a citizen with questions, there's plenty to learn and enjoy in Cohen's book. I hope to see him on some evening news/politics shows to provide much-needed context about the relationships between our branches of government.”
