The chairman of the Competition Authority determines the number and composition of the sections; he assigns the members of the Competition Authority to each of them.
Each section is chaired by the chairman of the Competition Authority or by one of the vice-chairmen or, where necessary to allow a case to be re-examined in a different panel, by the most senior member of the section. It comprises at least two other members. The vice-chairmen may deputise for each other if one of them is absent or prevented from attending.
