Illinois Law professor Lesley Wexler considers the significance of various countries’ responses to the rescue of 629 migrants on the Aquarius, a humanitarian rescue ship on the Mediterranean Sea.

Marci A. Hamilton, a Fox Distinguished Scholar in the Fox Leadership Program at the University of Pennsylvania, decries the policy of the Trump administration of separating children from their parents at US borders. Hamilton explains the trauma such a policy causes and calls upon individuals and organizations to shine a spotlight on its deeply negative consequences.

Illinois Law dean and professor Vikram David Amar comments on the lawsuit filed by the Trump administration against California over its so-called sanctuary policies. Amar explains why the federal government is likely to prevail on one claim, to lose on another claim, and to lose in part on the third claim. Amar laments that both sides seem to assert extreme positions that are not entirely tenable.

Illinois Law professor Lesley Wexler comments on the Windrush scandal developing in the United Kingdom, just one example of immigration policies that affect not only undocumented migrants present unlawfully but also undocumented citizens present lawfully.

George Washington law professor and economist Neil H. Buchanan comments on the apparent conflict between President Trump's declaration that the Deferred Action for Childhood Arrivals (DACA) program is unconstitutional and his decision to delay ending it. Buchanan considers whether the inconsistent positions with respect to the program actually affect the constitutional options available to him.

Cornell University law professor Michael C. Dorf argues that regardless of the outcome of President Trump's "Travel Ban 3.0" before the US Supreme Court, the litigation challenging the Travel Ban should be regarded as a victory over Trump's effort to rule by diktat. In support of this argument, Dorf points out that the litigation makes it abundantly clear to the American people that Trump remains every ounce the same vile and petty would-be tyrant that he appeared on the campaign trail.

Cornell University law professor Michael C. Dorf describes some of the key similarities and differences between the most recent iteration of President Trump’s ban on entry to the US by certain foreign nationals (“Travel Ban 3.0”) and earlier versions, and considers whether these differences will affect the determination of the policy’s legality. Although the Supreme Court might not ultimately be the court that answers the question, Dorf points out that we may have an answer before too long.

Cornell University law professor Joseph Margulies comments critically on the decision by the Bureau of Immigration and Customs Enforcement (ICE) to destroy certain records regarding detainees held in ICE custody. Margulies argues that the information ICE seeks to destroy can be helpful in assessing the conditions, staffing, supervision, and practices in various facilities, for the purpose of improving the worst ones and learning from the ones with the best practices.

Cornell University law professor Michael C. Dorf discusses possible implications and outcomes of the Supreme Court’s recent announcement that it will review the appeals court decisions invalidating President Trump’s travel ban executive order. Dorf explains the issue of mootness and also explains how one might predict how the Court will rule on the merits of the case.

SMU Dedman School of Law professor Joanna L. Grossman comments on the U.S. Supreme Court’s recent decision in Sessions v. Morales-Santana, in which the Court held unconstitutional a federal law imposing different physical presence requirements on mothers as compared to fathers. Grossman argues that the law at issue epitomized sex discrimination and was rooted in archaic generalizations about parents based on gender.

Cornell University law professor Michael C. Dorf comments on a recent decision by the U.S. Supreme Court on the heritability of citizenship and explains why the decision might have implications for other immigration issues, such as the “Muslim ban” executive order. Dorf argues that the precedents the Court had to distinguish to reach its conclusion might give some insight into whether and how it might defer to other political branches on immigration issues.

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 and UC Davis Law emeritus professor Alan E. Brownstein explain the complexities behind analyzing the motive underlying legislation and executive orders. Specifically, Amar and Brownstein highlight the difficulty in courts’ using perceived motive to strike down President Trump’s executive order regarding entry to the United States.

Chapman University, Fowler School of Law, professor Ronald D. Rotunda explains the legal precedent behind the executive’s power to restrict visas for non-U.S. citizens to enter the United States. Rotunda points out that the recent opinion by the U.S. Court of Appeals for the Ninth Circuit fails to mention almost any of the precedential cases on point when it struck down President Trump’s executive order limiting immigration.

Cornell University law professor Michael C. Dorf considers whether President Trump’s new executive order on immigration, anticipated to be issued this week, will fare better than Executive Order 13769, which temporarily banned nationals of seven predominantly Muslim countries and all refugees from entering the United States. Dorf discusses Trump’s past public statements advocating for a Muslim ban during his presidential campaign and applies the factors courts may use in evaluating whether those statements can be considered evidence of Trump’s motives for his actions as president, should the constitutionality of his executive order be challenged in court again.

Illinois Law dean Vikram David Amar and California civil litigator Michael Schaps consider the strength of San Francisco’s lawsuit against the Trump Administration arising out of its identity as a “sanctuary city.” Amar and Schaps discuss both the ripeness of the claim, a threshold procedural matter, and also the merits of San Francisco’s arguments.

Cornell University law professor Joseph Margulies argues that the significance of President Trump’s “Muslim Ban” executive order lies not in the legal issues it presents, but in its symbolism. As Margulies explains, the executive order is a symbol that will be used to mobilize support for competing narratives about American life; what ultimately matters is which narrative prevails.

John W. Dean, former counsel to President Nixon, explains the significance of the U.S. Supreme Court’s equal division in the immigration case United States v. Texas, which involved a challenge to the Obama administration’s sweeping immigration policy. Dean argues that the Court is effectively punting the political question of the immigration policy to the winner of the 2016 presidential election.

Cornell University law professor Michael C. Dorf evaluates statements made by Donald Trump in response to the mass shooting at a gay nightclub in Orlando this past weekend. Dorf argues that by telling American Muslims that they are all presumed to be terrorists, Trump actually fosters resentment and radicalization in the small portion of the American Muslim community that has the potential for radicalization.

Former counsel to the president John W. Dean analyzes Donald Trump’s proposal to build a wall along the Mexican-United States border. Dean explains why the wall is not only logistically unfeasible, but also why it is simply a bad idea as a matter of policy.
