The second of a two-part feature which assesses the advantages of the Competition Act 1998. Advises that the Act can be used to provide opportunities for firms looking to gain access to markets or to increase their market presence. Provides a practical example of how the Act would apply to a producer of widgets who is faced with a UK supplier with a dominant market position who refuses to supply a vital raw material. In such circumstances, the producer will be able to cite breach of the Act's prohibition on abuse of market dominance. Another example in which breach of the Act will lead to interim and final orders to terminate the infringement and damages is 'hard-core' cartels. Those suspecting a cartel will be able to complain to the Office of Fair Trading (OFT) and sue members of the cartel to recover overpayments. Concludes that such advantages of the Act balance potential risks for business, directors and senior executives.
