Longtime University of Texas Law Professor Sandy Levinson has teamed up with Jack Balkin of Balkinization fame to author a new SSRN paper, 13 Ways of Looking at Dred Scott. For a provocative abstract, check the following out:

Dred Scott v. Sanford is a classic case that is relevant to almost every important question of contemporary constitutional theory.
Dred Scott connected race to social status, to citizenship, and to being a part of the American people. One hundred fifty years later these connections still haunt us; and the twin questions of who is truly American and who American belongs to still roil our national debates.
Dred Scott is a case about threats to national security and whether the Constitution is a suicide pact. It concerns whether the Constitution follows the flag and whether constitutional rights obtain in federally held lands overseas. And it asks whether, as Chief Justice Taney famously said of blacks, there are indeed some people who have no rights we Americans are bound to respect.
Dred Scott remains the most salient example in debates over the legitimacy of substantive due process. It subverts our intuitions about the relative merits of originalism and living constitutionalism. It symbolizes the problem of constitutional evil and the question whether responsibility for great injustices lies in the Constitution itself or in the judges who apply it.
Finally, Dred Scott encapsulates the central problems of judicial review in a constitutional democracy. On the one hand, Dred Scott raises perennial questions about the judicial role in cases of profound moral and political disagreement, and about judicial responsibility for the backlash and political upheaval that may result from judicial review. On the other hand, the political context of the Dred Scott decision suggests that the Supreme Court rarely strays far from the wishes of the dominant national political coalition. It raises the unsettling possibility that, given larger social and political forces, what courts do in highly contested cases is far less important than we imagine.
