Commonwealth v Huon Channel and Peninsula Steamship Company Limited

The Commonwealth and the Collector of Customs for Tasmania brought an action against the Huon Channel and Peninsula Steamship Company Limited to recover light dues. The dispute concerned the liability of the defendant's steamship, the Ronnie, to pay light dues under the Commonwealth Light Dues Regulations 1915. The ship had made a voyage from Hobart to Port Esperance and back, passing the Derwent Light, which is a lighthouse under Commonwealth control located at the mouth of the River Derwent. The defendant argued that the ship was engaged in trading solely within the port of Hobart and therefore was not a "sea-going ship" as defined by the regulations. The case was heard by Barton J. in the High Court.

The court was required to determine two primary legal issues. Firstly, whether the steamship Ronnie, in the course of its voyage, "passed" the Derwent Light within the meaning of regulation 2 of the Commonwealth Light Dues Regulations 1915. Secondly, the court had to determine the meaning of "port" as used in the regulations, specifically whether the port of Hobart extended to encompass the area where the Derwent Light is situated, or if the light was located at the entrance to, or outside of, the port. The determination of these issues would establish whether the Ronnie qualified as a "sea-going ship" liable for light dues.

Barton J. held that a ship "passes" a lighthouse if it passes within the range of its visibility. On the evidence, the Ronnie came within the visibility range of the Derwent Light during its voyage. The court further held that the word "port" in the regulations should be interpreted in its commercial or business sense, meaning a place to which merchant vessels habitually go to load or discharge cargo. Applying this interpretation, the court found that the port of Hobart did not extend to the area of the Derwent Light. Consequently, the Ronnie's voyage to or from the port of Hobart involved passing the Derwent Light, rendering it a "sea-going ship" liable for light dues. The court therefore entered judgment for the plaintiffs with costs.
