Summarize the following paragraphs 12 Conclusion In the 2000s the decentralisation of the enforcement of EU competition law was meant to free Commission resources in order to adopt even more decisions

The decentralization of EU competition law enforcement in the 2000s was meant to free up resources for more decisions, but the "more economic" approach applied to specific cases resulted in an increase in resources devoted to each case. This approach required consideration of more factors and data and examination of issues previously not considered relevant. As a result, the overall number of decisions did not significantly increase, and some undertakings complained about the increased resources devoted to each case. The case law has sent mixed messages, and judgments may not always be univocal. Applying a "certainty" standard to economic analysis may move competition enforcement away from an effects-based approach. The administrative enquiry becomes more burdensome, and the Commission must deliver decisions that can resist challenges even on the basis of evidence not adduced during the administrative procedure. The trend objectively implies more complex investigations and more resources allocated to certain cases, which could result in some cases not being investigated.
