(26)The participation of each competent authority in a coordinated action, and in particular the investigation and enforcement measures that a competent authority is required to take should be sufficient in order to address the widespread infringement or widespread infringement with a Union dimension effectively.

However, a lack of available resources on the part of the competent authority concerned by that infringement should not be considered to justify not taking part in a coordinated action.
