Illinois Law dean and professor Vikram David Amar explains the federalism doctrines implicated by Attorney General Sessions’ attempt to deny funding to sanctuary jurisdictions. Amar points to lower court decisions that reflect a misunderstanding of the doctrines and calls upon federal courts and their law clerks to better understand and apply not just the nuanced technical details of various specific doctrines, but the overall federalism big picture as well.

Illinois Law dean and professor Vikram David Amar comments on recent actions by state and local governments to oppose federal policies, such as the immigration and the wall along the U.S.–Mexico border. Amar argues that these attempts likely run contrary to the Supremacy Clause of the U.S. Constitution by attempting to interfere with the execution of federal policy.

Illinois Law dean and professor Vikram David Amar discusses several legislative proposals in various states that purport to give state legislatures power to interpret and implement the federal Constitution notwithstanding judicial rulings interpreting the same. Amar explains some of the key differences between the different proposals and why some are likely to pass constitutional muster while others are not.

Cornell University law professor Michael Dorf argues that in some contexts, consideration of states’ rights is relevant to the interpretation of federal statutes, but in other contexts—including the federal lawsuit over a transgender boy’s access to a boys’ restroom at school—principles of federalism are outweighed by other considerations. Dorf provides three examples of instances where federalism should play a role in the interpretation of federal statutes, and he explains why the transgender bathroom case differs from those instances.
