    (b) and (c) [No change]

    (d) The need for evidence may be waived by the Office, Authority or the International Bureau under the conditions set and published by that Office, Authority or the International Bureau, as the case may be.

    (a) Any receiving Office, International Searching Authority, Authority specified for supplementary search, International Preliminary Examining Authority or the International Bureau may establish a period of extension such that time limits fixed in the Regulations within which a party has to perform an action before that Office, Authority or International Bureau may be extended when the State in which it is located is experiencing a general disruption caused by an event listed in Rule 82quater.1(a) which affects the operations at the said Office, Authority or International Bureau thereby interfering with the ability of parties to perform actions before that Office, Authority or International Bureau within the time limits fixed in the Regulations. The Office, Authority or the International Bureau shall publish the commencement and the end date of any such period of extension. The period of extension shall not be longer than two months from the date of commencement. The Office or Authority shall notify the International Bureau accordingly.

    (b) After establishing a period of extension under paragraph (a), the Office, Authority or the International Bureau concerned may establish additional periods of extension, if necessary under the circumstances. In that case, paragraph (a) applies mutatis mutandis.

    (c) The extension of a time limit under paragraph (a) or (b) need not be taken into account by any designated or elected Office if, at the time the information referred to in paragraph (a) or (b) is published, national processing before that Office has started.
