Cornell law professor Sherry F. Colb discusses the rationale behind Federal Rule of Evidence 609, which allows for impeachment of criminal defendants’ testimony with prior convictions, and the seminal cases applying that rule. Colb explains why the jury’s reaction to evidence of prior convictions is both predictable and irrational.
Cornell law professor Sherry F. Colb responds to a colleague’s claim (yet unconfirmed) that jurors have an easier time distinguishing truth from falsehood when they read a transcript of testimony than when they listen to and watch the testimony directly. Assuming the claim is true, Colb describes why that claim might at first be surprising and also why, on further consideration, it makes sense. She proposes that if the claim is true, we ought perhaps to consider whether the distractors inherent in live testimony should excludable under the Federal Rules of Evidence.
Cornell law professor Sherry F. Colb comments on a battle over what products may carry the label “milk.” Colb proposes that the dairy industry opposes plant-based milks (such as soy milk or almond milk) from identifying their products using the word “milk” not because of any real risk of confusing consumers or market harm, but as a show of dominance in response to exposed vulnerability.
Cornell law professor Sherry F. Colb comments on a decision the U.S. Supreme Court issued toward the end of the last term, in which a majority of the Court ruled that as long as police have probable cause for an arrest, it does not matter if their actual motivation for arresting someone violates the person’s First Amendment rights. Colb considers whether such pretextual, speech-based arrests are a problem, how they differ from other pretextual arrests, and how the ruling in this case resembles the law of a seemingly different area—post-conviction incarceration for convicted criminals.
Cornell law professor Sherry F. Colb cautions against using a disgust reaction alone to justify legislation—particularly legislation involving criminal penalties. Colb points out that disgust can sometimes help us determine that something bad is in fact going on, but we should not to allow disgust to power our moral choices without interrogation.
Cornell law professor Sherry F. Colb considers when the void-for-vagueness doctrine, which has a due process component, does and does not make sense. Colb argues that differences in the length of a criminal sentence have little or no deterrence effect, so imposing long sentences as an attempt to deter crimes is a waste of resources.
Cornell Law 3L Jareb A. Gleckel and professor Sherry F. Colb argue that President Trump’s overarching goal in his presidency is not to benefit the country but to create a legacy for himself, and a wall along the U.S.–Mexico border would be the pinnacle of such a legacy. Gleckel and Colb draw a comparison to Dr. Seuss’s character Yertle the Turtle, who had similar lofty ambitions, and call upon Americans to expose the President’s true motives and thus undercut his malign pursuits.
Cornell law professor Sherry F. Colb and George R. El-Khoury, JD, comment on a decision by the U.S. Supreme Court last month applying the “exigent circumstances” exception to the warrant requirement to permit the admission in evidence of a blood-alcohol test administered on an unconscious driver. Colb and El-Khoury describe some of the problems with using the exigent circumstances exception to arrive at the result in this case and propose some alternative approaches that might yield the same outcome but for stronger reasons.
Cornell law professor Sherry F. Colb comments on Tyson Foods’ recent entrance into the meat reduction market, selling so-called blended products that contain both meat and plants. Colb discusses some of the possible harms and benefits of Tyson’s decision from the perspective of an ethical vegan consumer.
Cornell law professor Sherry F. Colb discusses the criminal defenses of self-defense and defense of others and considers what role emotions should and do play in society’s assessment of whether a person’s violent conduct is justified and thus not criminally punishable. Colb argues that fear, rather than anger, most clearly motivates legitimate uses of self-defense or defense of others, but the mere fact of the victim’s anger (which might be present in addition to fear) should not necessarily mean the victim is criminally culpable.
Cornell law professor Sherry F. Colb discusses a question the U.S. Supreme Court will consider next term—whether the U.S. Constitution prohibits a state’s abolition of the insanity defense. Colb points out the various ways in which our current criminal justice system arbitrarily excuses some sources of criminal conduct but not others, and she argues that because of these inconsistencies already inherent in the system, the insanity defense cannot logically be required.
Cornell law professor Sherry F. Colb describes some ideological inconsistencies with the abortion law recently passed in Alabama, which prohibits all abortions except those necessary to protect against a serious health risk to the pregnant woman. Colb points out if an embryo or fetus and the woman carrying it are equally entitled to exist, then the exception for the serious health risk to the woman is inconsistent with that perceived equality. Colb also argues that the decision of Alabama lawmakers to penalize the abortion provider but not the abortion seeker similarly requires accepting on some level that a woman and her embryo or fetus are not co-equal occupants, which is inconsistent with the pro-life vision behind Alabama’s law.
Cornell law professor Sherry F. Colb comments on a recent decision by the US Court of Appeals for the Sixth Circuit holding unconstitutional the use of chalk by police officers to track whether a parked car has remained longer than permissible. Colb considers whether the decision—which seems to faithfully apply the US Supreme Court’s decisions in Jones v. United States and Florida v. Jardines—falls short of the “reasonable expectation of privacy” test the Court established in Katz v. United States. Colb proposes a test that instead combines trespass, information-gathering, as well as some privacy interest in that information, arguing that such a test would better reflect the scope of the Fourth Amendment.
Cornell law professor Sherry F. Colb discusses some of the she ideas she also expressed in a speech on identity politics. Specifically, Colb explains that the phenomenon of identity politics concerns two components: (1) identity and naming, and (2) victim culture.
Cornell law professor Sherry F. Colb describes two different attitudes toward patient autonomy using anecdotes—one of a cancer doctor and another of an abortion provider. Colb considers why the two attitudes differ and explain how the former can learn from the latter about patient empowerment.
Cornell law professor Sherry F. Colb comments on a case in which the US Supreme Court recently granted review, Ramos v. Louisiana, which presents the question whether states may permit conviction of an accused criminal on less than a unanimous jury voting “guilty.” Colb explains the doctrine of incorporation—by which most provisions of the Bill of Rights are held to be applicable as against the states as well as the federal government through the Fourteenth Amendment—and explains the possible significance of a unanimous jury verdict.
Cornell law professor Sherry F. Colb describes two different narrative lenses through which one could perceive (and interpret) the shooting of an unarmed African American man by a white police officer: the “Blue Lives Matter” narrative and the “Black Lives Matter” narrative. Colb explains how such narratives shape public reactions to such incidents, and she calls upon everyone to pay attention to the facts and feel less wedded to our narratives so that we may be better able to deal with and sometimes even prevent future hardship.
Cornell law professor Sherry F. Colb considers the significance in policing “original” meanings of words, such as “meat” and “marriage.” She point out that in both contexts, arguments over the meaning of the word are rooted in strong feelings about status and do not truly reflect a concern with a risk of confusion.
Cornell law professor Sherry F. Colb comments on an abortion bill that is currently under consideration in Virginia, arguing that the bill would excessively liberalize abortion laws in that state. Colb, who is pro-choice, points out that pro-choice theorists and activists should discern exactly why they believe in the right to terminate an unwanted pregnancy and draw—rather than resist—rational distinctions between a ball of cells and a newborn baby.
Cornell law professor Sherry F. Colb comments on a case the US Supreme Court recently agreed to review raising the question whether a state statute may constitutionally conduct a blood test on an unconscious driver suspected of drunk driving under a theory of “implied consent.” Colb explains the meaning of “implied consent”—deceivingly named, for there is no actual consent—and predicts that, consistent with the Court’s recent precedent on a similar issue, the state statute should be struck down.
