In 1984 the divestiture of AT&T's local telephone business created seven regional service monopolies known as Regional Bell Operating Companies or Incumbent Local Exchange Carriers. More than a decade later Congress enacted the Telecommunications Act of 1996 which restructured local telephone markets and imposed duties on the ILECs to facilitate entry by competitive local exchange carriers through resale of services at wholesale rates, leasing of unbundled network elements, or interconnection of facilities. William Twombly and Lawrence Marcus filed suit in the United States District Court for the Southern District of New York on behalf of a putative class of all subscribers of local telephone and high-speed internet services from February 8, 1996 to the present. They named as defendants four consolidated ILECs: BellSouth Corporation, Qwest Communications International Inc., SBC Communications Inc., and Verizon Communications Inc. The complaint alleged that these ILECs conspired to restrain trade by engaging in parallel conduct to inhibit CLECs, including unfair agreements for network access, inferior connections, overcharging, and billing practices designed to sabotage CLEC customer relations. The complaint further alleged that the ILECs agreed not to compete against one another in their respective territories. This agreement was inferred from their common failure to pursue business opportunities in contiguous markets and from a statement by Qwest CEO Richard Notebaert that competing in another ILEC's territory might be a good way to turn a quick dollar but that does not make it right. The complaint asserted that in light of the absence of meaningful competition among the ILECs and their parallel course of conduct the defendants had entered into a contract combination or conspiracy to prevent competitive entry and to allocate customers and markets. The district court dismissed the complaint for failure to state a claim. It concluded that the alleged parallel behavior was fully explained by each ILEC's independent interest in defending its own territory and that the complaint did not allege facts suggesting the decision to refrain from competing elsewhere was contrary to the ILECs' apparent economic interests. The Court of Appeals for the Second Circuit reversed, holding that plus factors need not be pleaded and that allegations of parallel conduct suffice if they leave open the possibility of collusion. The Supreme Court granted certiorari to address the proper standard for pleading an antitrust conspiracy through allegations of parallel conduct.

In March 1944 petitioner Fisher, the janitor at the library of the Cathedral of Saint Peter and Saint Paul in Washington, D.C., killed librarian Catherine Cooper Reardon inside the library building between eight and nine o'clock on the morning of March 1. Reardon had complained a few days earlier to the verger about Fisher's care of the premises, and the verger had informed Fisher of the complaint. Fisher and Reardon were alone in the library at the time of the homicide. Fisher testified that Reardon spoke insulting words about his work, after which he slapped her impulsively. He ran up a flight of steps toward an exit but turned back, seized a stick of firewood, struck her, and when the stick broke choked her to silence. He then dragged her to a lavatory and left the body to clean up some spots of blood on the floor outside. While Fisher was doing this cleaning up, the victim started hollering again. Fisher then took out his knife and stuck her in the throat. After that he dragged her body down into an adjoining pump pit, where it was found the next morning. Fisher's accounts of the events varied. His original confession made no reference to insulting words from Reardon. His written confession mentioned them, and his trial testimony amplified their effect on him. In the written confession he admitted his main reason for assaulting her was that she had reported him for not cleaning the floor. The Deputy Coroner testified that the knife wound was not deep and only went through the skin. Defense psychiatrists testified that Fisher was a psychopathic personality of a predominantly aggressive type, mentally somewhat below average, with minor stigmata of mental subnormalcy, and that he was unable by reason of a deranged mental condition to resist the impulse to kill. The prosecution introduced competent evidence that Fisher was capable of understanding the nature and quality of his acts. All evidence offered by the defense was received by the trial court. Fisher was tried in the District Court of the United States for the District of Columbia on an indictment charging killing by choking and strangling with deliberate and premeditated malice. The jury returned a verdict of guilty on the first count, and the court imposed a sentence of death. The United States Court of Appeals for the District of Columbia affirmed the judgment and sentence.

Two minors brought suit against Merrell Dow Pharmaceuticals, claiming they suffered limb reduction birth defects because their mothers had taken Bendectin, a drug prescribed for morning sickness to about 17.5 million pregnant women in the United States between 1957 and 1982. Limb reduction defects occur in fewer than one birth out of every 1000. Scientists do not know the mechanism by which any teratogen causes such defects. The plaintiffs offered testimony from three groups of experts. One group proposed to testify to a statistical link between Bendectin ingestion during pregnancy and limb reduction defects based on reanalyses of published studies that had reported no such association. A second group proposed to testify that Bendectin causes limb reduction defects in humans because it causes such defects in laboratory animals. A third group proposed to testify based on the similarity of Bendectin's chemical structure to other drugs suspected of causing birth defects. The district court granted summary judgment to Merrell Dow after excluding the plaintiffs' expert testimony. The Ninth Circuit affirmed that decision. The Supreme Court granted certiorari, reversed, and remanded for consideration under Federal Rule of Evidence 702. On remand, the Ninth Circuit examined the affidavits and prior trial testimony of the plaintiffs' experts. None of the experts had studied the effect of Bendectin on limb reduction defects before being hired to testify in this or related cases. None had published his work on Bendectin in a scientific journal. The only review their work had received was by judges and juries. Plaintiffs' epidemiological experts made vague assertions of a statistically significant relationship between Bendectin and birth defects but did not state that the relative risk exceeded two. With the exception of Dr. Palmer, the remaining experts were willing to testify only that Bendectin is capable of causing birth defects. Dr. Palmer alone was willing to testify that Bendectin did cause the limb defects in each of the children, based on his review of the plaintiffs' medical records and his conclusion that Bendectin is a teratogen.

In 1995 Samuel Mullet purchased land in Jefferson County, Ohio. That land became the Bergholz Amish community in 2001 when a sufficient number of ordained ministers qualified it as a separate Amish church district. The new community appointed Mullet as its bishop. As bishop, Mullet controlled all aspects of life in the Bergholz compound and had the ability to order the shunning of community members who failed to follow the tenets of their Amish faith. In 2006 Mullet excommunicated several church members who questioned Bergholz community practices and his leadership. Included in the group were Lavern and Mattie Troyer, whose son Aden was married to Mullet's daughter Wilma, as well as Melvin and Anna Shrock, whose son Emanuel was married to Mullet's daughter Linda. The excommunications led to family divisions, including a divorce and a custody dispute. Amish bishops from across the country met and voted unanimously to reverse the excommunications. From September 6 to November 9, 2011, several Bergholz community members committed five separate attacks on nine different individuals connected to the community by family or religious ties. The assailants sliced off the men's beards and cut the women's hair. The victims were seen as Amish hypocrites by the assailants. A federal grand jury indicted sixteen members of the Bergholz community for violating and conspiring to violate the Hate Crimes Prevention Act, as well as other charges. At trial, the government presented evidence that the assaults were motivated by the victims' religion, while the defendants presented evidence of personal and family disputes as alternative motives. The jury convicted all sixteen defendants of at least one hate-crime violation. The district court instructed the jury that the victims' religion need only be a significant motivating factor even if other reasons existed. The defendants twice requested a but-for causation instruction, which the court rejected. The defendants appealed their convictions to the United States Court of Appeals for the Sixth Circuit.
