This surprisingly taut and gripping book by NYU law professor Simon (What Kind of Nation
) examines the limits of presidential prerogative during the Civil War. Lincoln and Supreme Court Chief Justice Roger Taney saw eye to eye on certain matters; both, for example, disliked slavery. But beginning in 1857, when Lincoln criticized Taney's decision in the Dred Scott case, the pair began to spar. They diverged further once Lincoln became president when Taney insisted that secession was constitutional and preferable to bloodshed, and blamed the Civil War on Lincoln. In 1861, Taney argued that Lincoln's suspension of habeas corpus was illegal. This holding was, Simon argues, "a clarion call for the president to respect the civil liberties of American citizens." In an 1862 group of cases, Taney joined a minority opinion that Lincoln lacked the authority to order the seizure of Southern ships. Had Taney had the chance, suggests Simon, he would have declared the Emancipation Proclamation unconstitutional; he and Lincoln agreed that the Constitution left slavery up to individual states, but Lincoln argued that the president's war powers trumped states' rights. Simon's focus on Lincoln and Taney makes for a dramatic, charged narrative—and the focus on presidential war powers makes this historical study extremely timely. (Nov.)
