Abstract
The new Act of 21 April 2017 on claims for redressing damage caused by infringement of competition law is aimed at ensuring effective application of competition law in civil proceedings. To this end, the legislator decided to extent limitation periods for such claims. The new regulations which introduce the five-year limitation period are very advantageous for injured parties. Of considerable importance is also the provision stipulating that the period does not start while the infringement lasts. It is worth noting that the new regulations refer exclusively to infringement of the competition law which occurred after their effective date.
