Commonwealth Bank of Australia v Jason Hamilton; Commonwealth Bank of Australia v Karen Hamilton

In the Federal Court, the Commonwealth Bank of Australia sought to recover debts from Jason and Karen Hamilton. The bank had initially filed a claim against the Hamiltons, and they in turn filed a cross-claim against the bank. The bank subsequently amended its claim, adding additional particulars. The Hamiltons then sought to amend their cross-claim, but the bank opposed this application on the basis that the proposed amendments amounted to an allegation of forgery and would cause substantial prejudice.

The court was required to determine whether the Hamiltons should be granted leave to file a defence to the bank's amended claim, and if so, whether their proposed cross-claim amendments should be allowed. The court needed to consider whether the proposed allegations of forgery would cause substantial prejudice to the bank, and whether it was in the dictates of justice to permit the amendments. The court also had to consider whether any proposed paragraphs should be disallowed.

The court found that the Hamiltons should be granted leave to file a defence to the bank's amended claim, but that some of the proposed amendments to their cross-claim should be disallowed. The court held that the allegation of forgery, if proven, would not cause substantial prejudice to the bank, as the bank had already been put on notice of the Hamiltons' intention to rely on this defence. However, the court found that some of the proposed amendments were not relevant to the issues in the proceeding and would cause unnecessary expense and delay. The court held that it was in the dictates of justice to permit the amendments, but to disallow certain paragraphs.

The court made orders granting the Hamiltons leave to file a defence to the bank's amended claim, but disallowing certain paragraphs of their proposed cross-claim amendments. The court also made orders for costs.
