6.027. Must the late arrival of a document caused by irregularities in the mail service be excused? If a time limit fixed in the Treaty or the Regulations is exceeded because of the delayed arrival of a document or letter, it must be excused if it was caused by a delay in the mail or by an interruption of the mail service, provided that sufficient evidence is produced and the mailing was by mail registered with the postal authorities or with any delivery service notified by the designated Office to the International Bureau. Similarly, and under the same conditions, a new copy of a document or letter may be substituted for a document or letter lost in the mail, provided that the replacement document or letter is proved to be identical with the one lost. For details, see Rule 82.
