Such regular reviews are without prejudice to the Commission's power to undertake a specific review at any time where relevant developments make it necessary for the Commission to re-assess the determination made by this Decision. Based on the findings arising from a regular or specific review, the Commission may decide to amend or repeal this Decision at any time, in particular where developments affect the conditions on the basis of which this Decision is adopted.
