do not involve homicide or treason. Ashcroft v. Iqbal (2009): In a 5–4 decision written by Justice Kennedy, the court reversed the Second Circuit's decision not to dismiss a suit against former Attorney General John Ashcroft and others that claimed that the FBI engaged in discriminatory activities following the 9/11 attacks. The court also extended the heightened pleading standard established in Bell Atlantic Corp. v. Twombly (2006), which had previously applied only to antitrust law. The number of dismissals greatly increased after the Iqbal ruling. Citizens United v. Federal Election Commission (2010): In a 5–4 decision in which the majority opinion was delivered by Justice Kennedy, the Court held that the provisions of the Bipartisan Campaign Reform Act which regulated independent expenditures in political campaigns by corporations, unions, and non-profits violated First Amendment freedom of speech rights. National Federation of Independent Business v. Sebelius (2012): In a 5–4 decision written by Chief Justice Roberts, the Court upheld most of the provisions of the Patient Protection and Affordable Care Act, including the individual mandate to buy health insurance. The mandate was upheld as part of Congress's power of taxation. In a subsequent case, King v. Burwell (2015), the Court upheld the Patient Protection and Affordable Care Act, this time in a 6–3 opinion written by Chief Justice Roberts. In a third related case, California v. Texas (2021), the Court held that neither states nor individuals had the standing to challenge the PPACA's individual mandate due to the penalty being reduced to $0 in the Tax Cuts and Jobs Act of 2017. The 7–2 ruling was written by Justice Breyer. Arizona v. United States (2012): In a 5–3 decision delivered by Justice Kennedy, the Court held that portions of Arizona SB 1070, an Arizona law regarding immigration, unconstitutionally usurped the federal authority to regulate immigration laws and enforcement. Shelby County v. Holder (2013): In a 5–4 decision delivered by Chief Justice Roberts, the Court struck down Section 4(b) of the Voting Rights Act of 1965, which provided a coverage formula for Section 5 of the Voting Rights Act. The latter section requires certain states and jurisdictions to obtain federal preclearance before changing voting laws or practices, in an effort to prevent those states and jurisdictions from discriminating against voters. Without a coverage formula, Section 5 of the Voting Rights Act is no longer in effect. Burwell v. Hobby Lobby (2014): In a
