Antitrust Acts

Antitrust Acts Definition

Antitrust Acts are laws to scrutinize the Mergers and Acquisition activities and oversee that it doesn’t lead to one player becoming too big among its peers so that it has the power to take up predatory business policies. It is also known as competition laws. Herfindahl index and the Concentration ratios are commonly used measures to gauge the level of concentration in a market and there are certain ranges that specify different actions to be taken up by the antitrust bodies if the company’s HHI falls in any of these ranges.


In the US, the Sherman Act of 1890 was the first act in the antitrust domain and was later combined with the Clayton Act of 1914 & Federal Trade Commission Act of 1914 do form a comprehensive set of antitrust laws.

Sherman ActSherman ActSherman Antitrust Act is the legislation enacted by the US Congress to tackle monopolistic tendencies that reduce competition and interfere with trade and commerce. It prohibits deliberate or inorganic attempts to make competition unfair but not organic growth or monopolies formed through genuine more deals with market functioning and prohibitions of practices such as cartelsCartelsA cartel is a group of producers of goods or suppliers of services formed through an agreement amongst themselves to regulate the supply of goods or services with the basic intent to illegally regulate the prices or restrict competition regarding the said goods or more or collusion, which hamper free competition by creating high barriers to entry. Further, it also prohibits the abuse of monopoly power. Clayton Act deals with the Merger and Acquisition transactions. Federal Trade Commission act has given laws under civil and criminal categories, of which the FTC deals with civil cases, and the Department of Justice takes up the criminal cases.

Antitrust Acts Example

As explained in the history section, the Sherman Act, the Clayton Act, and the Federal Trade Commission Act form the Antitrust Act in the US. However, in different parts of the world, different Antitrust acts are in place.

For example, the antitrust act in India is known as The Competition Act, 2002, and is regulated by the Competition Commission of India. It came after replacing the Monopolies and Restrictive Trade Practices Act, 1969

Similarly, in Canada, the law is again known as The Competition Act, governed by the Competition Bureau, which involves cases of civil and criminal nature, and the Competition tribunal is the adjudicating body.

Who Enforces the Antitrust Laws in the US?

There are two enforcers of the antitrust laws in the US. The Federal government, along with the Federal Tax Commission, is one of the enforcers, and the US Department of Justice is another. In some cases, their roles and responsibilities overlap; however, in most cases, they are segregated. Therefore, before starting an investigation, there is an interdepartmental discussion between the two enforcers to prevent double effort.

One important point is the only the Department of Justice can take up cases of criminal nature. So if the FTC receives any such case, it has to transfer that to the Department of Justice. Further, within the civil segment, the FTC focuses on the high consumer spending sectors such as food, energy, healthcare, internet services, computer technology, among others.
