Commonwealth of Australia v Ryan

The Commonwealth of Australia appealed to the Full Federal Court against a judgment awarded to Mr Ryan, a former member of the Royal Australian Navy. Mr Ryan had claimed damages for loss of pension entitlement arising from the collision between HMAS Melbourne and HMAS Voyager.

The primary legal issues before the Full Federal Court were whether the trial judge had erred in failing to direct the jury on the basis of loss of a chance, and whether it was open to the jury to find that Mr Ryan had proven his loss of pension entitlement on the balance of probabilities. Additionally, the Court considered whether the judge had erred in awarding interest by adopting the reasons from an earlier case, and whether this constituted a failure to exercise discretion or an error in its exercise.

The Court held that the case had not been fought on the basis of loss of a chance, but rather on the proof of loss on the balance of probabilities, and the jury had been directed accordingly. No request for redirection had been made at trial, meaning the Commonwealth could not now complain about the direction given. The Court found that it was open to the jury to find that Mr Ryan had proven his loss of pension entitlement on the balance of probabilities. Furthermore, the Court determined that the judge's adoption of reasons from an earlier case for the award of interest was an exercise of discretion, and no error in that exercise had been established.

Consequently, the appeal was dismissed with costs.
