4.The action programmes and the individual measures provided for in paragraph 1 for which the Union's financial assistance exceeds EUR 5 million, and special measures for which the Union's financial assistance exceeds EUR 10 million, shall be adopted by the Commission in accordance with the procedure set out in Article 14 of this Regulation. That procedure shall not be required for action programmes and measures below those thresholds, and for non-substantial amendments thereto. Non-substantial amendments are technical adjustments such as extending the implementation period, reassigning funds within the forecast budget, or increasing or reducing the size of the budget by less than 20 % of the initial budget, but not exceeding EUR 10 million, provided that those amendments do not substantially affect the objectives of the initial action programme or measure. In such cases, action programmes and measures and non-substantial amendments thereto shall be adopted by the Commission, which shall inform the EDF Committee within one month of their adoption.Each Member State may request the withdrawal of a project or programme from an action programme submitted to the EDF Committee in accordance with the procedure set out in Article 14 of this Regulation. If such a request is supported by a blocking minority of Member States as laid down in Article 8(3) in connection with Article 8(2) of the Internal Agreement, the action programme shall be adopted by the Commission without the project or programme concerned. Unless the Commission, in line with the views of the Member States in the EDF Committee, wishes not to pursue the withdrawn project or programme it shall, at a later stage, be resubmitted to the EDF Committee outside the action programme in the form of an individual measure which shall then be adopted by the Commission in accordance with the procedure set out in Article 14 of this Regulation.On duly justified imperative grounds of urgency, such as crises, natural or man-made disasters or immediate threats to democracy, the rule of law, human rights or fundamental freedoms, the Commission may adopt individual or special measures or amendments to existing action programmes and measures, in accordance with the procedure referred to in Article 14(4) of this Regulation.
