1 2. The Authority, acting on its own authority or at the request of any individual or organisation having an interest, shall prohibit the continuation of any unfair commercial practices and eliminate their effects. To this end the Authority shall avail itself of the investigative and executive powers provided by the aforementioned Regulation 2006/2004/EC also in relation to offences which are not of a cross-border nature. In the performance of the tasks referred to in paragraph (1) above, the Authority may use the Guardia di Finanza (Customs and Excise Police) exercising their own powers to assess value added tax and income tax liability. Action by the Authority may take place independently of whether the consumers concerned in the territory of the member state in which the trader is resident, or in another member state.
