Rule 56(a)

In 1973 Congress enacted the Endangered Species Act to protect species of animals against threats to their continuing existence caused by man. In 1978 the Fish and Wildlife Service and National Marine Fisheries Service issued a joint regulation interpreting section 7(a)(2) to require federal agencies to consult with the Secretary of the Interior on actions taken in foreign nations. In 1986 the Secretary promulgated a revised regulation that limited the consultation obligation to actions within the United States or on the high seas. Shortly after the 1986 regulation took effect, Defenders of Wildlife and other environmental organizations filed suit in the United States District Court for the District of Minnesota against the Secretary of the Interior. The complaint sought a declaratory judgment that the regulation was invalid as to its geographic scope and an injunction requiring the Secretary to promulgate a new regulation mandating consultation for foreign projects. The complaint alleged that the absence of consultation would increase the rate of extinction of endangered and threatened species. The complaint further alleged that some of the organizations' members observed these species both domestically and abroad. Respondents supported their allegations with affidavits from two members. Joyce Kelly stated that she had traveled to Egypt in 1986, observed the habitat of the endangered Nile crocodile, and intended to return. Kelly further stated that she would suffer harm from the United States role in the rehabilitation of the Aswan High Dam. Amy Skilbred stated that she had traveled to Sri Lanka in 1981, observed the habitat of endangered species including the Asian elephant and leopard at the site of the Mahaweli project funded by the Agency for International Development, and intended to return. Skilbred admitted she had no current plans to return because of a civil war. The District Court dismissed the complaint for lack of standing. The Court of Appeals for the Eighth Circuit reversed. On remand the District Court denied the Secretary's motion for summary judgment on standing. The District Court granted respondents' motion for summary judgment on the merits and enjoined the Secretary from applying the regulation to foreign countries. The Eighth Circuit affirmed. The Supreme Court granted certiorari.

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 September 1980 respondent Catrett, as administratrix of her husband's estate, commenced a wrongful-death action in the Superior Court of the District of Columbia against fifteen named corporations including petitioner Celotex Corporation. The complaint alleged that her husband Louis H. Catrett died in 1979 from exposure to asbestos products manufactured or distributed by the defendants. The action was removed to the United States District Court for the District of Columbia on diversity grounds. After extensive discovery Celotex filed a motion for summary judgment in September 1981 asserting that respondent had failed to produce any evidence that the decedent had been exposed to Celotex asbestos products. In response respondent produced a transcript of the decedent's deposition taken in a separate California proceeding, a letter from an official of one of Celotex's former insurance companies, and a letter from one of Celotex's customers. In July 1982 the District Court granted summary judgment to Celotex on the ground that respondent had made no showing of exposure to Celotex products in the District of Columbia or elsewhere within the statutory period. Respondent appealed only that ruling. A divided panel of the Court of Appeals for the District of Columbia Circuit reversed, holding that Celotex had failed to meet its initial burden because it made no effort to adduce affirmative evidence supporting its motion. The Supreme Court granted certiorari to resolve a conflict among the circuits concerning the proper standard under Rule 56.

Sandra Adickes, a white school teacher from New York, was working as a volunteer teacher at a Freedom School for Negro children in Hattiesburg, Mississippi, during the summer of 1964. On August 14, 1964, Adickes went with six of her Negro students to the Hattiesburg Public Library, where the librarian refused to allow the students to use the library and summoned the chief of police, who ordered the group to leave. The group then went to the S. H. Kress & Co. store in Hattiesburg to have lunch. Adickes filed suit against Kress in the United States District Court for the Southern District of New York seeking damages under 42 U.S.C. § 1983. After the group sat down at the lunch counter, a policeman entered the store and observed them. A waitress took the orders of the Negro students but refused to serve Adickes on the ground that she was a white person in the company of Negroes. The group left the store without being served. As they reached the sidewalk, the same policeman arrested Adickes on a vagrancy charge. The vagrancy charge against Adickes was subsequently changed, and she was tried and acquitted. Her complaint contained two counts under § 1983. One count alleged that Kress had refused her service pursuant to a custom of the community to segregate the races in public eating places that was enforced by the State. The other count alleged that the refusal of service and the arrest were the product of a conspiracy between Kress employees and the Hattiesburg police. Kress moved for summary judgment on the conspiracy count and submitted depositions from the store manager, the waitress, and the arresting officers, along with affidavits from police officials, all denying any agreement or communication with the police about refusing service or making the arrest. Adickes opposed the motion by pointing to her deposition statement and an unsworn statement from a Kress employee indicating that a policeman had been in the store at the time of the refusal. The District Court granted summary judgment on the conspiracy count, holding that Adickes had failed to allege facts from which a conspiracy might be inferred. After a trial on the custom count, the District Court directed a verdict for Kress because Adickes had not proved other instances of whites being refused service while in the company of Negroes. The Court of Appeals for the Second Circuit affirmed the District Court's rulings on both counts. The Supreme Court granted certiorari to review the case.

Roger Reeves worked for Sanderson Plumbing Products, Inc. for forty years until his discharge in October 1995 at the age of fifty-seven. He supervised the regular line in the Hinge Room, where Joe Oswalt supervised the special line and Russell Caldwell managed the department. Reeves's duties included recording employee attendance and hours and reviewing weekly attendance reports. In the summer of 1995, after being told that production was down due to employee absences and tardiness, manufacturing director Powe Chesnut ordered an audit of the Hinge Room timesheets for July, August, and September. The audit uncovered numerous timekeeping errors and misrepresentations by Caldwell, Reeves, and Oswalt. Chesnut, along with vice presidents Dana Jester and Tom Whitaker, recommended to company president Sandra Sanderson that Reeves and Caldwell be fired, and Sanderson discharged both in October 1995. Reeves filed suit in June 1996 in the United States District Court for the Northern District of Mississippi, alleging that his termination violated the Age Discrimination in Employment Act. At trial, Sanderson contended that Reeves was fired for failing to maintain accurate attendance records, while Reeves introduced evidence that his records were accurate and that Chesnut had shown age-based animus toward him. The jury found in Reeves's favor, awarding thirty-five thousand dollars in compensatory damages and determining that the discrimination was willful, resulting in a seventy-thousand-dollar judgment plus an award of front pay. The Court of Appeals for the Fifth Circuit reversed the judgment, concluding that Reeves had not presented sufficient evidence that his age motivated the employment decision even though he may have shown the company's explanation was pretextual. The court considered factors such as the context of Chesnut's comments, the ages of other decisionmakers, and the fact that multiple supervisors were accused of recordkeeping issues. The Supreme Court granted certiorari to address the evidentiary requirements in such discrimination cases.
