If a Member State considers it necessary to adopt new legislation, it shall notify the Commission and the other Member States of the envisaged measures and give the reasons justifying them.

The Commission shall consult the Committee referred to in Article 14(1), if it considers such consultation to be useful or if a Member State so requests, and shall give an opinion on the envisaged measures.

The Member State concerned may take the envisaged measures only six months after the notification referred to in paragraph 1, and provided that the Commission's opinion is not negative.

If the Commission's opinion is negative, it shall determine, in accordance with the procedure referred to in Article 14(2) and before the expiry of the period referred to in the first subparagraph of this paragraph, whether the envisaged measures may be implemented. The Commission may require certain amendments to be made to the envisaged measures.
