In a landmark judgment dated October 29, 2013, the Competition Appellate Tribunal (COMPAT) has recognized the concept of ‘Relevant Turnover’ for calculation of penalty in cartel cases. The COMPAT, in its order, accepted the contention that in the case of multi-product companies, the penalty for cartelisation should be calculated on the basis of the ‘Relevant Turnover’ instead of overall turnover of the entire company/group.
