"13 In my judgment this Application to Amend raises, in the case of the First and Fourth grounds, entirely new matters completely different in nature from his original claims presented on30 March 2007 and raise completely new issues. On balance, I consider that in all the circumstances the prejudice to Teen Spirit would be greater than to Mr Mackenzie in allowing them to proceed by way of amendment to his existing claims. In relation to the Second and Third grounds, these also raise new issues although said to be connected to his existing claims. Again, I consider the prejudice to Teen Spirit in allowing these claims now to be added outweigh the prejudice to Mr Mackenzie in refusing his Application to Amend."
