Article 20 1

1.   Where the market surveillance authorities of one Member State have sufficient reason to believe that a product covered by this Directive does not comply with the applicable accessibility requirements, they shall carry out an evaluation in relation to the product concerned covering all requirements laid down in this Directive. The relevant economic operators shall fully cooperate with the market surveillance authorities for that purpose.

Where, in the course of the evaluation referred to in the first subparagraph, the market surveillance authorities find that the product does not comply with the requirements laid down in this Directive, they shall without delay require the relevant economic operator to take all appropriate corrective action to bring the product into compliance with those requirements within a reasonable period, commensurate with the nature of the non-compliance, as they may prescribe.

Market surveillance authorities shall require the relevant economic operator to withdraw the product from the market, within an additional reasonable period, only if the relevant economic operator has failed to take adequate corrective action within the period referred to in the second subparagraph.

Article 21 of Regulation (EC) No 765/2008 shall apply to the measures referred to in the second and third subparagraphs of this paragraph.
