The means referred to in paragraph 1 shall include provisions whereby persons or organizations, having a legitimate interest under national law in protecting consumers, may take action according to the national law concerned before the courts or before competent administrative bodies for a decision as to whether contractual terms drawn up for general use are unfair, so that they can apply appropriate and effective means to prevent the continued use of such terms.
