523. The Court of Appeal may, if the ends of justice so require, permit a party to amend his written proceedings, to implead a person whose presence is necessary, or even, in exceptional circumstances, to adduce, in such manner as it directs, indispensable new evidence.
It has all the powers necessary for the exercise of its jurisdiction and may make any order necessary to safeguard the rights of the parties. It may even, notwithstanding the expiry of the time allowed by article 494, but provided that more than six months have not elapsed since the judgment, grant special leave to appeal to a party who shows that in fact it was impossible for him to act sooner. However such leave cannot be granted in respect of a judgment rendered in the circumstances contemplated in article 198.1.
