Each subsequent document filed in a proceeding must be endorsed, by the party filing the document, with the same number as that assigned by a Registrar to the originating application for the proceeding or to the notice of appeal.
Note: When an originating application that is not a cross - claim or a
notice of appeal is filed, a Registrar will assign a distinctive number to the
document and will endorse the document with that number. The number will
include a reference to the Registry in which the document is filed and the
calendar year in which the document is filed. A new series of numbers will be
started at the beginning of each calendar year.
