Why do we need competition law?

Competition law wants to support the functioning of the CARICOM Single Market and Economy (CSME) area.  Therefore, the rules of articles 175-179 Treaty of Chaguaramas  on the prohibition of anti-competitive business conduct and the abuse of a dominant position in a market ensure that enterprises do not prevent, restrict or distort competition in a manner that prevents the market from functioning properly. Consumer welfare is the main goal of competition law. 

Where to find consumer- and competition law in the CARICOM legislation?

The Treaty of Chaguaramas is regulating in chapter 8, art. 168- 186, competition policy and consumer protection.
