The Corrosive Effect Of Inevitable Discovery On The Fourth Amendment, Tonja Jacobi, Elliot Louthen

Faculty Articles

The Supreme Court has only once, almost four decades ago, addressed the doctrine of inevitable discovery, when it established the exception in Nix v. Williams. Inevitable discovery encapsulates the notion of no harm, no foul—if law enforcement would have discovered unlawfully obtained evidence regardless of a constitutional violation, then the resulting evidence need not be excluded. Nix laid out two simple dictates: the eponymous requirement of inevitability and a corresponding evidentiary burden requiring the prosecution to prove by a preponderance of the evidence that law enforcement inevitably would have discovered the evidence without the violation. Such analysis requires counterfactual …

Supreme Irrelevance: The Court’S Abdication In Criminal Procedure Jurisprudence, Tonja Jacobi, Ross Berlin

Faculty Articles

Criminal procedure is one of the Supreme Court’s most active areas of jurisprudence, but the Court’s rulings are largely irrelevant to the actual workings of the criminal justice system. The Court’s irrelevance takes two forms: objectively, on the numbers, its jurisprudence fails to protect the vast majority of people affected by the criminal justice system; and in terms of salience, the Court has sidestepped the major challenges in the United States today relating to the criminal justice system. These challenges include discrimination in stops and frisks, fatal police shootings, unconscionable plea deals, mass incarceration, and disproportionate execution of racial minorities. …

The original constitutional taint disappears in the wash.

Courts have allowed evidence laundering in a variety of contexts, from cases involving flawed databases to cases stemming from faulty judgments and communication lapses in law enforcement teams. …

Mapp V. Ohio Revisited: A Law Clerk's Diary, Polly J. Price

Faculty Articles

The 1960 Supreme Court Term laid the groundwork for the subsequent revolution in the relationship between state and federal law accomplished by the Supreme Court under Chief Justice Earl Warren. The "most famous search and seizure case in American history" - Mapp v. Ohio - would be decided that Term. Mapp held that the Fourth Amendment's protection against "unreasonable searches and seizures" required the exclusion of evidence found through an illegal search by state and local police officers, extending to the states a rule that had previously applied only to federal law enforcement. Mapp became a pivotal chapter in the …
