The Court noted that validity and regularity of a bill are different concepts - a bill could be valid but irregular, or invalid but nevertheless regular. The Court observed that an order dismissing an action for provisional sentence without leave to enter into the principal case, where the only issue between the parties has been disposed of, is final in effect and thus appealable, as no purpose would be served by allowing entry into the principal case. The Court remarked that the obligation of a debtor liable on a bill to an immediate party arises from the transaction pursuant to which the bill was delivered, and all disagreements from such transaction may be aired when sued by the holder. However, a holder in due course is above such disputes and may only be met by absolute defences that go to the root of the bill's validity, but this immunity comes at the price that the bill must be complete and regular on its face.
