“In considering whether or not it is desirable to add a new party pursuant toCPR r 19.2 (2)two lodestars are the policy objective of enabling parties to be heard if their rights may be affected by a decision in the case and the overriding objective in CPR Pt 1”
“The overriding objective is that the court should deal with cases justly. That includes, so far as practicable, ensuring that each case is dealt with not only expeditiously but also fairly. Amendments in general ought to be allowed so that the real dispute between the parties can be adjudicated upon provided that any prejudice to the other party or parties caused by the amendment can be compensated for in costs, and the public interest in the efficient administration of justice is not significantly harmed.”
