Cornell University law professor Michael C. Dorf comments on the recent oral argument before the U.S. Supreme Court in United States v. Texas, a case involving a challenge to the Obama Administration’s deferred action immigration policy. Dorf points out that underneath the procedural questions actually before the Court in that case is a crucial unasked question: What is the scope of the president’s prosecutorial discretion not to enforce laws duly enacted by Congress?

Illinois Law dean and law professor Vikram David Amar evaluates three people’s statements regarding America’s treatment of Muslims: President Obama, an Iowa businessman, and a local Muslim cleric (an imam). Amar points out that Donald Trump’s proposal that America ban all Muslims from entering the country is vastly underinclusive (because the great majority of violent acts in this country are perpetrated by non-Muslims), and at the same time very overinclusive (because the overwhelming majority of Muslims who want to enter the United States intend no harm)—two indicators of legal and moral unfairness.

University of Illinois law professor and dean Vikram David Amar comments on a recent decision by a federal district court in Arizona addressing a challenge to two parts of Arizona’s SB 1070 statute, which attempts to deal with immigration stresses in that state. Amar argues that the court’s reasoning on both claims was confused and unpersuasive and that the results should have been inverted. That is, Amar suggests that the court should have upheld the equal protection challenge to the “Show Me Your Papers” provision and rejected the First Amendment challenge to the Day Laborer provisions.

Cornell University law professor Michael Dorf discusses Donald Trump’s call to end birthright citizenship as part of immigration reform. Dorf argues that birthright citizenship implements widely shared and characteristically American values and that curtailing it would be a huge step backwards.

Cornell University law professor Michael Dorf discusses the U.S. Supreme Court’s decision, released earlier this week, in Kerry v. Din, in which the Court rejected a claim that a U.S. citizen was entitled to a detailed explanation of why the government would not allow her husband a visa to enter the country.

Cornell University law professor Michael Dorf discusses the Obama Administration’s options in light of the recent decision by a federal district judge to enjoin implementation of deferred action for several million undocumented immigrants.

Chapman University law professor Ronald Rotunda comments on the President’s asserted power to waive U.S. immigration laws.

Justia columnist and Hofstra law professor Joanna Grossman discusses the important questions of whether and when a child who is born outside the U.S. can acquire citizenship from a U.S. citizen parent. Grossman focuses especially on the heartbreaking case of U.S. citizen Ellie Lavi, who gave birth to twins in Israel. When Lavi sought U.S. citizenship for the twins, the State Department informed her that the twins would not be deemed U.S. citizens unless Lavi could prove that the donor sperm or egg came from a U.S. citizen. Grossman strongly criticizes the State Department’s decision to, in effect, deem the gamete donors, not Lavi, the babies’ parents for purposes of U.S. citizenship—even though no one disputes that Lavi, a U.S. citizen, gave birth to the twins. Grossman covers the ways in which children can gain U.S. citizenship by descent; describes the more onerous rules for out-of-wedlock children; considers whether treating unwed citizen fathers and unwed citizen mothers differently is discriminatory; and discusses who counts as a “mother” and thus a person able to convey citizenship. Finally, Grossman considers four interesting scenarios regarding the descent of citizenship to children; describes the consequences of non-citizenship; and urges the State Department to deal more fairly and justly with the modern realities of reproductive technology.

Justia columnist and Cornell law professor Michael C. Dorf comments on the Supreme Court’s decision to take up a case involving the controversial Arizona immigration law—another blockbuster in a momentous Term for the Court, which will also resolve cases on the health care legislation and redistricting in Texas. Regarding the Arizona immigration case, Dorf explains the relevance, in the case, of the theory of the “unitary executive,” and notes that there seems to be a common misconception: The question in the Arizona case, he explains, is not whether Congress can preempt state immigration law—it plainly can—but whether Congress did, in fact, preempt Arizona’s immigration law. Dorf also explains the unusual way in which the Justices’ ideological leanings play out in typical federal-preemption cases, and why immigration cases involving federal preemption are atypical in this respect. In addition, he explains why a Court precedent on gun control and federalism may play a large role here.

Justia columnist and Cornell law professor Michael Dorf examines the way in which an Alabama immigration law—which would place the state in the role of enforcer of federal immigration laws—illustrates a schism that may be growing between two conservative constituencies: populists and corporatists. Dorf illustrates his point about the schism by reference to the controversies over the Troubled Assets Relief Program (TARP) and over immigration, which have split the Republican Party. He also asks if populist conservatives and business conservatives can ever truly get along—and notes ways in which the Supreme Court has been surprisingly supportive of the populists.
