In United States federal law, the Daubert standard is a rule of evidence regarding the admissibility of expert witness testimony. A party may raise a Daubert motion, a special motion in limine raised before or during trial, to exclude the presentation of unqualified evidence to the jury. The Daubert trilogy are the three United States Supreme Court cases that articulated the Daubert standard:
United States v. Montoya De Hernandez, 473 U.S. 531 (1985), was a U.S. Supreme Court case regarding the Fourth Amendment's border search exception and balloon swallowing.
United States v. Russell, 411 U.S. 423 (1973), is a Supreme Court case dealing with the entrapment defense. The court split 5-4 and maintained the subjective theory that had first been adopted in Sorrells v. United States, 287 U.S. 435 (1932). Although an undercover federal agent had helped procure a key ingredient for an illegal methamphetamine manufacturing operation, and assisted in the process, the Court followed its earlier rulings on the subject and found that the defendant had a predisposition to make and sell illegal drugs whether he worked with the government or not.
United States of America v. $124,700 in U.S. Currency, 458 F.3d 822, was a decision of the United States Court of Appeals for the Eighth Circuit that was handed down on August 18, 2006.
An ultimate issue in criminal law is a legal issue at stake in the prosecution of a crime for which an expert witness is providing testimony.
The Center on the Administration of Criminal Law is a think-tank dedicated to the promotion of good government and prosecution practices in criminal matters. Its work has been the subject of a feature story in the Associated Press.
United States v. Weitzenhoff, 35 F.3d 1275 is a legal opinion from the Ninth Circuit Court of Appeals that addresses the confusing mens rea requirement of a federal environmental law that imposed criminal sanctions on certain polluters. The main significance of the court's opinion was that it interpreted the word "knowingly" in the statute to mean a general awareness of the wrongfulness of one's actions or the likelihood of illegality, rather than an actual knowledge of the statute being violated. Circuit Court Judge Betty Binns Fletcher authored the majority's legal opinion in this case.
Melendez-Diaz v. Massachusetts, 557 U.S. 305 (2009), is a United States Supreme Court case in which the Court held that it was a violation of the Sixth Amendment right of confrontation for a prosecutor to submit a chemical drug test report without the testimony of the person who performed the test. While the court ruled that the then-common practice of submitting these reports without testimony was unconstitutional, it also held that so called "notice-and-demand" statutes are constitutional. A state would not violate the Constitution through a "notice-and-demand" statute by both putting the defendant on notice that the prosecution would submit a chemical drug test report without the testimony of the scientist and also giving the defendant sufficient time to raise an objection.
The American Foundation for Equal Rights (AFER) was a nonprofit organization active in the United States from 2009 through 2015. The organization was established to support the plaintiffs in Hollingsworth v. Perry, a federal lawsuit challenging California's Proposition 8 under the Due Process and Equal Protection Clauses of the Fourteenth Amendment to the United States Constitution. AFER retained former United States Solicitor General Theodore B. Olson and David Boies to lead the legal team representing the plaintiffs challenging Proposition 8.
The Supreme Court of the United States handed down nineteen per curiam opinions during its 2009 term, which began on October 5, 2009, and concluded October 3, 2010.
Fujifilm Corp v. Benun, 605 F.3d 1366 was a case in which the United States Court of Appeals for the Federal Circuit affirmed the judgment made by the United States District Court for the District of New Jersey that the defendants infringed patents owned by Fujifilm Corporation.
The Supreme Court of the United States handed down fourteen per curiam opinions during its 2011 term, which began October 3, 2011 and concluded September 30, 2012.
Chambers v. Mississippi, 410 U.S. 284 (1973), was a United States Supreme Court case in which the Court held that a state may not enforce its rules of evidence, such as rules excluding hearsay, in a fashion that disallows a criminal defendant from presenting reliable exculpatory evidence and thus denies the defendant a fair trial.
McFadden v. United States, 576 U.S. 186 (2015), was a United States Supreme Court case in which the Court held that section 841 of the Controlled Substances Act requires the government to prove that to be in criminal violation, a defendant must be aware that an analogue defined by the Controlled Substance Analogue Enforcement Act with which he was dealing was a controlled substance.
Bell v. Cone, 535 U.S. 685 (2002), was a Supreme Court of the United States case that upheld a death sentence despite the defendant's argument that he should not be sentenced to death because he was suffering from drug-induced psychosis when he committed the crimes. Cone also argued that he was denied effective assistance of counsel because his attorney failed to present sufficient mitigating evidence during the sentencing phase of his trial and that his attorney inappropriately waived his final argument during the sentencing phase. In an 8–1 opinion written by Chief Justice William Rehnquist, the United States Supreme Court denied Cone's petition for a writ of habeas corpus. The Court held that the actions taken by Cone's attorney during the sentencing phase were "tactical decisions" and that the state courts that denied Cone's appeals did not unreasonably apply clearly established law. Justice John Paul Stevens wrote a dissenting opinion in which he argued that Cone was denied effective assistance of counsel because his attorney failed to "subject the prosecution's case to meaningful adversarial testing."
Cone v. Bell, 556 U.S. 449 (2009), was a case in which the United States Supreme Court held that a defendant was entitled to a hearing to determine whether prosecutors in his 1982 death penalty trial violated his right to due process by withholding exculpatory evidence. The defendant, Gary Cone, filed a petition for postconviction relief from a 1982 death sentence in which he argued that prosecutors violated his rights to due process under the Fourteenth Amendment by withholding police reports and witness statements that potentially could have shown that his drug addiction affected his behavior. In an opinion written by Justice John Paul Stevens, the Supreme Court held that Cone was entitled to a hearing to determine whether the prosecution's failure to disclose exculpatory evidence violated Cone's right to due process; the Court noted that "the quantity and the quality of the suppressed evidence lends support to Cone’s position at trial that he habitually used excessive amounts of drugs, that his addiction affected his behavior during his crime spree". In 2016, Gary Cone died from natural causes while still sitting on Tennessee's death row.
Kimmelman v. Morrison, 477 U.S. 365 (1986), was a decision of the U.S. Supreme Court that clarified the relationship of the right to effective assistance of counsel under the Sixth Amendment to other constitutional rights in criminal procedure. In this case, evidence against the defendant was probably seized illegally, violating the Fourth Amendment, but he lost the chance to argue that point due to his lawyer's ineffectiveness. The prosecution argued that the defendant's attempt to make a Sixth Amendment argument via a habeas corpus petition was really a way to sneak his Fourth Amendment argument in through the back door. The Court unanimously disagreed, and held that the Fourth Amendment issue and the Sixth Amendment issue represented different constitutional values, and had different requirements for prevailing in court, and therefore were to be treated separately by rules of procedure. Therefore, the habeas corpus petition could go forward. In its opinion, the Court also gave guidance on how to apply its decisions in Stone v. Powell and Strickland v. Washington.
United States v. Throckmorton is an 1878 decision of the U.S. Supreme Court on civil procedure, specifically res judicata, in cases heard at equity. A unanimous Court affirmed an appeal of a decision by the District Court for California upholding a Mexican-era land claim, holding that collateral estoppel bars untimely motions to set aside the verdict where the purportedly fraudulent evidence has already been considered and a decision reached. In the opinion it distinguished between that kind of fraud, which it called intrinsic, and extrinsic fraud, in which deceptive actions exterior to the proceeding prevented a party, or potential party, to the action from becoming aware of the possibility they could vindicate their rights in court.
Pulsifer v. United States,, is a pending United States Supreme Court case regarding 18 U.S.C. § 3553, the federal sentencing statute.
