Citizens United v. FEC (2010): Campaign Finance and Corporate Speech

Case at a Glance

What Is Citizens United?

Citizens United v. Federal Election Commission is the 2010 Supreme Court decision that fundamentally reshaped American campaign finance law. In a 5-4 ruling, the Court held that the First Amendment prohibits the government from limiting independent political expenditures by corporations, labor unions, and other associations. The decision overturned a century of campaign finance restrictions and directly enabled the rise of super PACs — independent political organizations that can raise and spend unlimited sums on elections.

How the Case Began: Hillary: The Movie

Citizens United is a conservative non-profit corporation based in Washington D.C. In 2007-2008, it produced a 90-minute documentary film called Hillary: The Movie, which was sharply critical of Hillary Clinton as she sought the Democratic presidential nomination. Citizens United wanted to make the film available through video-on-demand cable services within 30 days of the 2008 Democratic primary elections.

The Federal Election Commission determined that distributing the film would violate Section 203 of the Bipartisan Campaign Reform Act of 2002 (BCRA), also known as the McCain-Feingold Act. Section 203 prohibited corporations and unions from using their general treasury funds to pay for electioneering communications — broadcast, cable, or satellite messages that refer to a clearly identified federal candidate within 30 days of a primary or 60 days of a general election. Citizens United sued the FEC, challenging the restriction as a violation of its First Amendment rights.

The Narrow Ground Citizens United Sought vs. the Broad Ruling the Court Gave

Citizens United initially asked the Court to rule narrowly — either that Section 203 did not apply to its particular film or that the FEC had misapplied it. The Supreme Court reargued the case in 2009 and directed the parties to brief the broader question: should Austin v. Michigan Chamber of Commerce (1990) — the precedent upholding restrictions on corporate political spending — be overruled?

This expansion of the question was itself controversial. Justice Stevens's dissent argued that the Court had unnecessarily reached out to decide a much larger constitutional question than the case required. The majority's choice to address and overturn Austin was the defining feature of the decision.

Justice Kennedy's Majority Opinion

Justice Anthony Kennedy wrote for the 5-justice majority. His analysis rested on 3 core propositions.

First: Political Speech Is at the Core of the First Amendment

Kennedy opened by emphasising that political speech — speech about candidates for public office — sits at the heart of what the First Amendment protects. Restrictions on the amount of money that can be spent to engage in political speech are restrictions on political speech itself. The more money a speaker is prohibited from spending, the less speech is available to that speaker.

Second: Corporations Have First Amendment Rights

The government argued that corporations were different from individual speakers and could be restricted in ways that individual speakers could not. Kennedy rejected this. The First Amendment's text refers to freedom of speech with no distinction between individual and corporate speakers. Prior Supreme Court decisions had already recognized that the First Amendment applies to corporations. The identity of the speaker is not sufficient justification for suppressing the speaker's message. Corporations, unions, associations, and other entities that aggregate individual voices do not lose constitutional protection simply because they are organized in corporate form.

Third: Independent Expenditures Cannot Corrupt

The government's strongest argument for BCRA's restrictions was the anti-corruption interest. Large corporate spending on elections, the government argued, creates the appearance or reality of corruption — that elected officials will favour the corporations that spent heavily to elect them. Kennedy acknowledged that preventing actual corruption — quid pro quo bribery — was a legitimate and compelling government interest. But he held that independent expenditures, by their very nature, cannot constitute or create the risk of quid pro quo corruption.

An independent expenditure is political spending that is not coordinated with a candidate or political party. The candidate does not control the message, the timing, or the amount. Because there is no direct exchange — no specific spending in exchange for a specific political favour — the spending cannot logically be corrupt in the relevant sense. The majority assumed, without substantial evidence, that independent spending would in practice be genuinely independent.

Overruling Austin and Part of McConnell

With these 3 propositions in place, Kennedy concluded that Austin v. Michigan Chamber of Commerce (1990), which had upheld restrictions on corporate political spending on an anti-distortion rationale, must be overruled. Austin had reasoned that the enormous wealth that corporations accumulate through the corporate form could distort the marketplace of political ideas in ways that bore no relationship to the public's actual support for the corporations' political views. Kennedy rejected this rationale as incompatible with the First Amendment's protection of political speech and with the principle that the government cannot level the playing field among speakers by restricting some speakers' access to the political marketplace. The relevant part of McConnell v. FEC (2003), which had upheld BCRA's Section 203 restrictions, was also overruled.

What the Court Left in Place

Citizens United did not invalidate all campaign finance restrictions. The Court upheld BCRA's disclaimer and disclosure requirements, which require that ads identify who paid for them. Justice Kennedy wrote that disclosure enables the electorate to make informed decisions and give proper weight to different speakers and messages. Citizens United also did not address direct contribution limits — the rules capping how much individuals or entities can give directly to candidates or political parties. Those limits remain constitutional.

Justice Stevens's Dissent

Justice John Paul Stevens wrote a 90-page dissent, one of the longest in the Court's history, joined by Justices Ginsburg, Breyer, and Sotomayor. Stevens argued that the majority had fundamentally misread the history of the First Amendment and the relationship between corporations and political speech in American law. He contended that the framers of the Constitution never intended to give corporations the same First Amendment rights as individual citizens, that a long tradition of restricting corporate political spending predated the Constitution, and that the Court's decision would have profound and harmful consequences for the democratic process.

Stevens predicted that the ruling would flood American elections with corporate money, that it would increase the influence of wealthy interests over elected officials, and that it would undermine the public's confidence in the democratic system. His dissent's closing warning — that the Court's blunder threatens to undermine the integrity of elected institutions across the nation — has been widely cited by critics of the decision.

President Barack Obama criticised the decision directly in his January 2010 State of the Union address, the first such direct presidential rebuke of a specific Supreme Court decision in modern history. Several of the justices present visibly reacted to the remarks.

What Citizens United Did to American Elections

The practical effects of Citizens United have been enormous. The decision enabled the creation of super PACs — political action committees that can raise unlimited amounts of money from corporations, unions, and individuals and spend it on independent political expenditures. In the 2010 midterm elections — the first major election after Citizens United — outside spending more than doubled compared to 2006. By the 2012 presidential election, super PACs had raised and spent more than $600 million. By the 2020 election cycle, outside spending exceeded $3 billion.

Citizens United also contributed to the growth of what critics call dark money — political spending by non-profit organisations that do not disclose their donors. Whereas super PACs must report their donors to the FEC, certain non-profit organisations classified under Section 501(c)(4) of the tax code (social welfare organisations) can engage in political spending without disclosing donors. Citizens United enabled this spending; the lack of disclosure requirements for these groups' donors has been one of the most contested aspects of the post-Citizens United landscape.

Is Citizens United Still in Effect?

Is Citizens United still the law? Yes, as of 2026. Citizens United has not been overruled or significantly limited by subsequent Supreme Court decisions. Congress has attempted to pass legislation requiring greater disclosure of political spending, but such measures have not become law. A constitutional amendment to overrule Citizens United has been proposed but has not advanced through Congress.

Timeline

Citizens United v. FEC is the most debated campaign finance decision in American legal history, a ruling that its defenders describe as the restoration of First Amendment rights to political speech and that its critics describe as the opening of the floodgates for the corruption of American democracy by concentrated private wealth.
