3. At the request of a Member State or on its own initiative, the Commission may, within a period of three months after the day on which it receives notice under paragraph 1, review the process for the introduction of an operating restriction. Where the Commission finds that the introduction of a noise-related operating restriction does not follow the process set out in this Regulation, it may notify the relevant competent authority accordingly. The relevant competent authority shall examine the Commission notification and inform the Commission of its intentions before introducing the operating restriction.
