(1) All courts must take judicial notice of—
(a) the signature of a person who is, or was, a member of the Tribunal or the principal registrar or another registrar; and
(b) the fact that a person referred
to in paragraph (a) is or was a member, the principal registrar or
another registrar
(as the case requires); and
(c) the official seal of the Tribunal affixed to a document.
