53. Permission to amend statements of case

(1) The Court may allow an amendment whose effect will be to add or substitute a new claim after a period of limitation has expired, but only if the new claim arises out of the same, or substantially the same, facts as a claim in respect of which the party applying for permission has already claimed a remedy in the proceedings.
(2) The Court may allow an amendment to correct a mistake as to the name of a party, but only where the mistake was genuine and not one which would cause reasonable doubt as to the identity of the party in question.
(3) The Court may allow an amendment to alter the capacity in which a party claims if the new capacity is one which that party had when the proceedings started or has since acquired.
