Greenhouse offers a fascinating institutional biography of a place and its people-men and women who exercise great power but whose names and faces are unrecognized by many Americans and whose work often appears cloaked in mystery. How do cases get to the Supreme Court? How do the justices go about deciding them? What special role does the chief justice play? What do the law clerks do? How does the court relate to the other branches of government? Greenhouse answers these questions by depictingthe justices as they confront deep constitutional issues or wrestle with the meaning of confusing federal statutes. Throughout, the author examines many individual Supreme Court cases to illustrate points under discussion, ranging from Marbury v. Madison, the seminal case which established judicialreview, to the recent District of Columbia v. Heller (2008), which struck down the District of Columbia's gun-control statute and which was, surprisingly, the first time in its history that the Court issued an authoritative interpretation of the Second Amendment. To add perspective, Greenhouse also compares the Court to foreign courts, revealing interesting differences. For instance, no other country in the world has chosen to bestow life tenure on its judges. The second edition of Greenhouse's Very Short Introduction tracks the changes in the Court's makeup over the last eight years, considers the landmark decisions of the Obama and Trump eras, and reexamines the precarious fates of such precedents as Roe v. Wade.
