Cornell University law professor Sherry Colb comments on a recent decision by the Court of Appeals of Indiana, holding that police violated their suspect’s Fourth Amendment rights by acquiring, without a warrant, the suspect’s cell site information from his cell phone provider. Colb explains the Indiana court’s reasoning and discusses the evolving law regarding people’s privacy expectations in information their cell phones store and transmit.

Cornell University law professor Sherry Colb discusses a recent decision by New York’s highest court expanding the definition of parental status to include same-sex partners intending to parent. Colb explains the court’s ruling and discusses a U.S. Supreme Court decision regarding the rights of non-parents that might stand in the New York court’s way.

Cornell University law professor Sherry F. Colb considers whether the termination of Zika pregnancies might affect our thinking about abortion. Specifically, Colb asks (1) whether it is right to end a pregnancy because the baby would be severely disabled if brought to term, and (2) whether it is right at all to take the life of a fetus late in pregnancy, given that birth defects caused by Zika are not detectable by ultrasound until late in pregnancy.

In light of a recent decision by the Oregon Supreme Court, Cornell University law professor Sherry F. Colb considers whether taking blood from a dog constitutes a search of the dog’s owner for Fourth Amendment purposes. Colb identifies good and bad features of the court’s opinion and expresses what, in her view, would have been the ideal resolution of the case.

Cornell University law professor Sherry Colb comments on the Indiana abortion law that Donald Trump’s chosen running mate, Mike Pence, signed into law as governor of that state. Colb explains the different reasons that women have for terminating their pregnancies and argues that while some of the reasons women actually choose abortion might be repugnant to some of us, that should not undermine their right to make that choice.

Inspired by a Dan Savage podcast on the topic, Cornell University law professor Sherry Colb considers both the concept of “virtuous pedophiles” and some of its potential implications. Colb explains what this term means and draws several comparisons to other individuals who may be oriented toward a certain action that is either illegal or prohibited to them, ultimately expressing ambivalence toward the notion of the virtuous pedophile.

Cornell University law professor Sherry F. Colb comments on the U.S. Supreme Court’s recent decision in Birchfield v. North Dakota, in which the Court held that states may criminalize the refusal to take a breathalyzer test but may not criminalize the refusal to take a blood test, absent a warrant, as an ordinary incident of an arrest for driving while impaired. Colb explains why the Court distinguished the two types of tests and argues that the decision effectively balances competing interests in public safety and individual privacy.

Cornell University law professor Sherry F. Colb discusses the U.S. Supreme Court’s recent decision in Utah v. Strieff, holding that evidence found in that case as a result of a Fourth Amendment violation was not the direct consequence of the violation and was therefore properly admitted into evidence against the defendant under the attenuation doctrine. Colb explains how one throwaway line in the opinion, if taken to its logical conclusion, could potentially spell the death of the exclusionary rule.

Cornell University law professor Sherry F. Colb considers the changing meaning of the U.S. Supreme Court’s opinion in Miller v. Alabama, which held that mandatory life sentences without the possibility of parole. Colb discusses specifically the Court’s decision earlier this year in Montgomery v. Lousiana, which held that Miller must be applied retroactively on state collateral review.

Cornell University law professor Sherry F. Colb comments on an Oklahoma abortion restriction law that the governor vetoed last month. Colb argues that this law more authentically reflects the pro-life perspective on abortion than other laws that have passed in other states but explains why it makes more sense to pass legislation that stands a chance of surviving judicial scrutiny, even if it does not authentically capture a proponent’s genuine view of the issue at stake.

Cornell University law professor Sherry F. Colb comments on a case currently before the U.S. Supreme Court, in which the Court will decide whether evidence located during a search incident to arrest after an unlawful stop will be admissible in evidence against the arrestee. Colb discusses this and also the broader question of the future role of the exclusionary rule in the law of the Fourth Amendment.

Cornell University law professor Sherry Colb comments on a case on which the the U.S. Supreme Court recently heard oral argument that presents the question whether a state law may, absent a search warrant, attach criminal penalties to a DUI suspect’s refusal to undergo a chemical test of the suspect’s blood, urine, or breath to determine alcohol concentration. Colb predicts that the Court will decide that any test of a person’s internal state—whether through a blood draw, a breathalyzer, or a urine sample—requires a search warrant in the absence of exigent circumstances.

Cornell University law professor Sherry Colb considers how the U.S. Supreme Court, acting as a mediator, might approach the parties in Zubik v. Burwell, a case currently before the Court in which the Court made the unusual request of supplemental briefing from the parties. Colb explains both the capabilities and limitations of transformative mediation as a method of resolving disputes.

Cornell University law professor Sherry Colb analyzes Donald Trump’s recent statement—which he subsequently changed—that women who have abortions should be punished for doing so. Colb points out that this position is actually more logically coherent than the more conventional position taken by anti-abortion advocates that the provider be punished for performing an abortion.

Cornell University law professor Sherry Colb considers the moral question whether we have the right to benefit from discoveries made by outrageous rights violations. Colb considers the example of James Marion Sims—known as the father of modern gynecology—whose research on female slaves, without providing them the available anesthesia, led to his development of a technique to repair obstetric fistulas. Further, Colb calls into question the presumed rightfulness of experimenting on nonhuman animals.

Cornell University law professor Sherry Colb examines the boundaries of moral permission to be the object of someone’s fantasies. Colb considers several different situations that are similar but likely elicit various degrees of responses from readers before concluding that fantasy should be the private prerogative of the fantasizer that should not be subject to either legal or moral regulation.

Cornell University law professor Sherry Colb considers the perspectives of both sides of the controversy over a relatively new California law requiring licensed pregnancy centers to prominently post a notice about the availability of free or low-cost abortion, contraception, and prenatal care. Colb offers a compelling narrative to illustrate each perspective, ultimately concluding that while she personally agrees with one side neither is “right” in a moral sense.

Cornell University law professor Sherry Colb discusses a decision by the U.S. Court of Appeals for the Second Circuit holding that when police are outside the threshold of a home arresting a suspect who is inside the threshold, it is a “home arrest” requiring a warrant. Colb explains why the decision is significant in protecting the home as a space where a person can feel the highest degree of privacy and comfort, free from unreasonable government intrusions.

Cornell University law professor Sherry Colb discusses the recent trend of anti-abortion groups joining custody battles over frozen embryos on the side of the parent that seeks implantation. Colb argues that this position is consistent with their deeply held view that life begins at conception—much more so than their more usual stance in battles over abortion regulation.

Cornell University law professor Sherry Colb discusses the role of Pennsylvania Rule of Evidence 404 in the criminal trial against Bill Cosby. Colb argues that the rule against character evidence serves a specific purpose in “whodunit” cases (where the perpetrator is unknown) but that it may serve a different purpose in “what was done” cases, such as the present case against Cosby.
