New from Oxford University Press: (Oct. 2016), by 
David L. Sloss (Santa Clara University - School of Law). A description from the Press:
This book provides the first detailed history of the Constitution's 
treaty supremacy rule. It describes a process of invisible 
constitutional change. The traditional supremacy rule provided that all 
treaties supersede conflicting state laws; it precluded state 
governments from violating U.S. treaty obligations. Before 1945, treaty 
supremacy and self-execution were independent doctrines. Supremacy 
governed the relationship between treaties and state law. Self-execution
 governed the division of power over treaty implementation between 
Congress and the President. In 1945, the U.S. ratified the UN Charter, 
which obligates nations to promote human rights "for all without 
distinction as to race." In 1950, a California court applied the 
Charter's human rights provisions and the traditional treaty supremacy 
rule to invalidate a state law that discriminated against Japanese 
nationals. The implications were shocking: the decision implied that the
 United States had effectively abrogated Jim Crow laws throughout the 
South by ratifying the UN Charter. In response, conservatives mobilized 
support for a constitutional amendment, known as the Bricker Amendment, 
to abolish the treaty supremacy rule. The amendment never passed, but 
Bricker's supporters achieved their goals through de facto constitutional change. The de facto
 Bricker Amendment created a novel exception to the treaty supremacy 
rule for non-self-executing (NSE) treaties. The exception permits state 
governments to violate NSE treaties without authorization from the 
federal political branches. The death of treaty supremacy has 
significant implications for U.S. foreign policy and for U.S. compliance
 with its treaty obligations. 
A few blurbs of note:
"The Death of Treaty Supremacy makes a major contribution to 
our understanding of American constitutionalism. It demonstrates the 
evolutionary nature of constitutional law, identifies the complex 
practical forces that drive its evolution, and highlights yet another 
flaw in constitutional 'originalism.' It shows that historical changes 
have transformed the Constitution's meaning even on an issue where the 
'original' meaning was actually clear and specific--that properly 
ratified treaties are 'supreme' over state law." -Edward A. Purcell Jr. 
"David
 Sloss has written a fascinating case study on a central constitutional 
queýstion - how does the interpretation of the constitution change? 
Moreover, Sloss has taken as his example a pressing issue of 
contemporary constitutional debate- the role of treaties as domestic law
 in state and federal courts. His fine-grained and wide-reaching 
research and his thoughtful analysis benefits us all." -Judith Resnik
