In many ways it was business as usual at the Australian Competition and Consumer Commission (ACCC) in 2009. Under the chairmanship of Graeme Samuel, the authority continued to live up to its well-earned reputation as one of the world's leading competition enforcers, with a generally well-chosen, balanced caseload of behavioural and merger cases. Most of the lawyers GCR contacted had few major criticisms of the ACCC's work last year.
