His Lordship went on to say at p 191, "The question ... is, whether this is pleadable as a defence, where the matter which is to undo the release has not yet happened. I think it is. The old rule was that a right of action once suspended is gone for ever. To avoid that, where it was evidently contrary to what the parties intended, the Court of Exchequer Chamber, in Ford v Beech, construed the agreement, not as suspending the plaintiff's remedy on the promissory notes there sued upon, but as giving the defendant merely a right of action for breach thereof, if the plaintiff sued whilst the payments were continued, that is, as a covenant not to sue for a limited period. It must, however, be taken to be established that, where a covenant not to sue is in terms expressed to be intended as a release, and where the rights of a surety do not intervene, it is, in order to avoid circuity of action, an answer to the plaintiff's claim. A release which in terms is subject to a defeasance amounts to a covenant not to sue, except upon the happening of the event contemplated. Such a release is not open to the objection taken in Ford v Beech. It very rarely could happen that matter subsequent could undo that which had suspended the plaintiff's right of action, and therefore practically it was enough to say that a right of action once suspended is gone forever ...". In other words, the court was not dealing with a release, strictly so called, but with a covenant not to sue.
