 * Alaska sees record snowfall.
 * The U.S. Supreme Court makes an 8–1 decision in Minneci v. Pollard that abused inmates cannot sue a privately, state-hired prison company in federal court. The ruling went against prisoner Richard Lee Pollard in a dispute of damages over a violation of the Eighth Amendment's prohibition against cruel and unusual punishment, claiming that Wackenhut/GEO, a privately run federal prison in California, had deprived him of adequate medical care. Writing for the majority, Associate Justice Stephen Breyer said that "... the existence of an Eighth Amendment-based damages action ... against ... a privately operated federal prison .. state tort law authorizes adequate alternative damages actions, ... actions that provide both significant deterrence and compensation ... For these reasons, where, as here, a federal prisoner seeks damages from privately employed personnel working at a privately operated federal prison, where the conduct allegedly amounts to a violation of the Eighth Amendment, and where that conduct is of a kind that typically falls within the scope of traditional state tort law (such as the conduct involving improper medical care at issue here), the prisoner must seek a remedy under state tort law. We cannot imply a Bivens remedy in such a case. The judgment of the Ninth Circuit is reversed."
 * January 14 – Miss Wisconsin, Laura Kaeppeler, wins Miss America pageant.
 * January 16
 * Zappos.com computer system is hacked, compromising the personal information of 24 million customers.

 * January 18
 * The U.S. Supreme Court makes a unanimous 9–0 decision that telephone consumers can gain standing in federal courts to sue abusive telephone marketers. The ruling went against Arrow Financial Services (Arrow), a debt-collection agency, in a dispute of standing over the federal jurisdiction of the Telephone Consumer Protection Act (TCPA) of 1991. The act was passed so that out-of-state telemarketers, by operating interstate, could not escape state-law prohibitions on intrusive nuisance calls. Petitioner Marcus D. Mims filed a damages action in Federal District Court, alleging that respondent Arrow, seeking to collect a debt, violated the TCPA by repeatedly using an automatic telephone dialing system or prerecorded or artificial voice to call Mims's cellular phone without his consent. Writing for the unanimous court, Associate Justice Ruth Bader Ginsburg said that "We find no convincing reason to read into the TCPA's permissive grant of jurisdiction to state courts any barrier to the U. S. district courts' exercise of the general federal-question jurisdiction ... We hold, therefore, that federal and state courts have concurrent jurisdiction over private suits arising under the TCPA ... The Eleventh Circuit erred in dismissing Mims's case for lack of subject-matter jurisdiction ... The judgment of the United States Court of Appeals for the Eleventh Circuit is reversed, and the case is remanded for further proceedings consistent with this opinion."
 * The U.S. Supreme Court makes a 6–2 decision that restores copyright status to some foreign works previously in the public domain. The case challenges the constitutionality of the application of Section 514 of the Uruguay Round Agreements Act (URAA), a treaty seeking to equalize copyright protection on an international basis. The practical effect of the decision is that some works that were once free to use (such as Prokofiev's Peter and the Wolf, Metropolis (1927), The Third Man (1949), the works of Igor Stravinsky, several works of H. G. Wells, including the film Things to Come (1936), as well as innumerable others) now must be paid for. The ruling went against Lawrence Golan, and many others, in a dispute of URAA bringing some works whose copyright had lapsed back under copyright. Writing for the majority, Associate Justice Ruth Bader Ginsburg said that "... (if there is) ... copyright protection abroad ... (then there must be given) ... the same full term of protection ... (in the) ...U. S. ... Congress did so in §514 of the Uruguay Round Agreements Act (URAA), which grants copyright protection to preexisting works of Berne member countries, protected in their country of origin, but lacking protection in the United States ... The judgment of the Court of Appeals for the Tenth Circuit is therefore affirmed."
 * January 19

 * January 23
 * The U.S. Supreme Court makes a unanimous 9–0 decision that government officials must obtain a search warrant permitting them to install a Global-Positioning-System (GPS) tracking device on citizens' private property. The ruling involves a Fourth Amendment case, the requirement of obtaining a valid warrant in searches by law enforcement. The court ruled in favor of Antoine Jones in a dispute that attaching a GPS device to private property in a public space still constitutes a search and therefore falls under the Fourth Amendment. The opinion of the court was written by Associate Justice Antonin Scalia who said that "We decide whether the attachment of a Global-Positioning-System (GPS) tracking device to an individual's vehicle, and subsequent use of that device to monitor the vehicle's movements on public streets, constitutes a search or seizure within the meaning of the Fourth Amendment ... The Fourth Amendment provides in relevant part that '[t]he right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated.' It is beyond dispute that a vehicle is an 'effect' as that term is used in the Amendment. United States v. Chadwick, 433 U. S. 1, 12 (1977). We hold that the Government's installation of a GPS device on a target's vehicle, and its use of that device to monitor the vehicle's movements, constitutes a 'search.'"

 * The U.S. Supreme Court makes a 6–3 decision that law enforcement officials do not need to issue Miranda warnings to prison inmates under questioning if these inmates are warned that they may end the interrogation at any time. The ruling involves an inmate who was removed from the general prison population and questioned. The court ruled against convict Randall Fields in a dispute that questioning without Miranda invocation was proper as long as the convict was advised of his freedom to leave. The opinion of the court was written by Associate Justice Samuel Alito who said that "The United States Court of Appeals for the Sixth Circuit held that our precedents clearly establish that a prisoner is in custody within the meaning of Miranda v. Arizona, 384 U. S. 436 (1966), if the prisoner is taken aside and questioned about events that occurred outside the prison walls. Our decisions, however, do not clearly establish such a rule, and therefore the Court of Appeals erred inholding that this rule provides a permissible basis for federal habeas relief under the relevant provision of the Antiterrorism and Effective Death Penalty Act of 1996(AEDPA), 28 U. S. C. §2254(d)(1). Indeed, the rule applied by the court below does not represent a correct interpretation of our Miranda case law. We therefore reverse."
