(171)The market surveillance authorities should have the right to require economic operators to take corrective action on the basis of findings either that packaging is not compliant with sustainability and labelling requirements or that the economic operator has infringed other rules on the placing or making available on the market of packaging. In order to ensure uniform conditions for the implementation of the requirement on economic operators to take corrective action, implementing powers should be conferred on the Commission to decide whether a national measure is justified.
