In its recent study of professions for the Competition Authority, Indecon identified five tests for professionals in determining whether or not they are competitive. These involve the entry requirements to a profession, and their possible use to restrict entry to the profession; the existence of free competition between members of the profession; the question of allowing advertising by the profession; the demarcation of the profession's functions in such a way as possibly to restrict the activities of other groups; and the freedom or otherwise of the profession's members to form limited companies of multidisciplinary practices.
