Within three months from the date of publication in the Official Journal of the European Union, the authorities of a Member State or of a third country, or a natural or legal person having a legitimate interest and established in a third country may lodge a notice of opposition with the Commission.

Any natural or legal person having a legitimate interest, established or resident in a Member State other than that from which the application was submitted, may lodge a notice of opposition with the Member State in which it is established within a time limit permitting an opposition to be lodged pursuant to the first subparagraph.

A notice of opposition shall contain a declaration that the application might infringe the conditions laid down in this Regulation. A notice of opposition that does not contain this declaration is void.

The Commission shall forward the notice of opposition to the authority or body that lodged the application without delay.

If a notice of opposition is lodged with the Commission and is followed within two months by a reasoned statement of opposition, the Commission shall check the admissibility of this reasoned statement of opposition.

Within two months after the receipt of an admissible reasoned statement of opposition, the Commission shall invite the authority or person that lodged the opposition and the authority or body that lodged the application to engage in appropriate consultations for a reasonable period that shall not exceed three months.

The authority or person that lodged the opposition and the authority or body that lodged the application shall start such appropriate consultations without undue delay. They shall provide each other with the relevant information to assess whether the application for registration complies with the conditions of this Regulation. If no agreement is reached, this information shall also be provided to the Commission.

At any time during these three months, the Commission may, at the request of the applicant extend the deadline for the consultations by a maximum of three months.

Where, following the appropriate consultations referred to in paragraph 3 of this Article, the details published in accordance with Article 50(2) have been substantially amended, the Commission shall repeat the scrutiny referred to in Article 50.

The notice of opposition, the reasoned statement of opposition and the related documents which are sent to the Commission in accordance with paragraphs 1 to 4 of this Article shall be in one of the official languages of the Union.

In order to establish clear procedures and deadlines for opposition, the Commission shall be empowered to adopt delegated acts, in accordance with Article 56, complementing the rules of the opposition procedure.

The Commission may adopt implementing acts laying down detailed rules on procedures, form and presentation of the oppositions. Those implementing acts shall be adopted in accordance with the examination procedure referred to in Article 57(2).
