antitrust law

Competition law, known in the United States as antitrust law, has three main elements:It may prohibit agreements or practices that restrict free trading and competition between business entities. This includes in particular the repression of cartels.It may ban abusive behaviour by a firm dominating a market, or anti-competitive practices that tend to lead to such a dominant position. Practices controlled in this way may include predatory pricing, tying, price gouging, refusal to deal and many others.It may supervise the mergers and acquisitions of large corporations, including some joint ventures. Transactions that are considered to threaten the competitive process can be prohibited altogether, or approved subject to "remedies" such as an obligation to divest part of the merged business or to offer licences or access to facilities to enable other businesses to continue competing.

United States antitrust law is the body of laws that prohibits anti-competitive behavior (monopoly) and unfair business practices. These competition laws make illegal certain practices deemed to hurt businesses or consumers or both, or generally to violate standards of ethical behavior.  Government agencies known as competition regulators regulate antitrust laws and may also be responsible for regulating related laws dealing with consumer protection. The term "antitrust" was originally formulated to combat "business trusts," now more commonly known as cartels. Other countries use the term "competition law." Many countries including most of the Western world have antitrust laws of some form; for example the European Union has provisions under the Treaty of Rome to maintain fair competition, as does Australia under their Trade Practices Act 1974.
