Paycorp Payment Solutions v Peter Singyin Chai

The case of Paycorp Payment Solutions v Peter Singyin Chai involved a dispute over the defendants' application to amend their defence after the plaintiff had presented its case. The defendants sought to include defences of illegality and unclean hands, which they had not initially raised in their defence. The case was heard in a court of law in Australia. The primary issue before the court was whether the defendants should be permitted to amend their defence to include the new defences at such a late stage in the proceedings, despite the plaintiff's case being already closed.

The court examined the doctrine of illegality and considered whether the purpose of the impugned transaction was of evidentiary significance or the foundation of the claim to establish a trust. It was determined that the fact the defences had poor prospects of success was one relevant factor in deciding whether to allow the amendment. The court also noted that evidence supporting the defences had been alluded to in correspondence between the parties in 2010 and had been available since September 2011. The defendants had made the application to amend their defence after serving this evidence, yet they did not include the defences of illegality and unclean hands.

The court found that the application by the defendants to amend their defence to include the new defences of illegality and unclean hands was refused. The court emphasised that allowing the amendment at such a late stage would be inappropriate given the poor prospects of success of the proposed defences and the fact that the evidence supporting these defences had been available for some time. This decision highlights the importance of timely and comprehensive pleadings in legal proceedings, particularly when it comes to the potential for late amendments to include new defences.
