Moore v British Waterways Board  EWCA Civ 73 – read judgment
A boat owner has won his appeal against the British Waterways Board preventing him from mooring his boats alongside his land on a tidal stretch of the Grand Canal. Although he had no common law right to permanently moor the boats, he had committed no actionable wrong in doing so, and they were therefore not moored “without lawful authority” within the meaning of the British Waterways Act 1983. This judgment is an interesting and important endorsement of the principle in English law that everything is permitted except what is expressly forbidden.
This key “rule of law” principle applies as much to the BWB as it does to the police and other law enforcement agencies.
The facts of this case are set out in my post on the Chancery Division’s judgment. It will be remembered that Hildyard J held that a riparian owner had no right, simply by reason of his ownership of land on the banks of a river, to moor a vessel alongside that land and therefore issued an order requiring that Mr Moore remove his vessels. The question before the Court of Appeal was not so much whether the appellant had a positive mooring right, but whether the BWB had a general power under section 8 of the 1983 Act to order the removal of vessels moored on the canal without its permission.
The Court allowed the appeal.
Reasoning behind the judgment
Riparian owners on tidal waters have more restricted rights than those in non tidal areas. The latter are presumed to own the bed up to the mid-point between the two banks. In tidal waters the presumption is that the river or canal bed is owned by the Crown. While a riparian owner was entitled to the natural flow of the watercourse passing his property, there was no authority for the proposition that, as against the owner of the bed of the waterway, he was entitled to maintain a floating structure or vessel indefinitely. On the other hand, whilst the common law did not recognise a riparian right to permanently moor, the absence of that right did not necessarily connote the commission of a wrong such as to render the mooring unlawful. Giving the leading judgment, Mummery LJ observed that
the mindset at trial [in the Chancery Division] was naturally influenced by the positive nature of the mooring right asserted by the claimant i.e. that under the common law he had a riparian right to moor vessels permanently in that particular stretch of the GUC and that provided the “lawful authority” answer to the s.8 notices served by BWB.
The problem with that approach was that it “sidelined” the question that should have been at the centre of the dispute: whether, quite apart from any established riparian right, the claimant was doing anything unlawful at common law by the mooring of his vessels along side the canal bank in that part of the GUC.
BWB’s statutory power to require removal of the vessels did not extend in terms to the removal of any vessels moored in the GUC without its permission: it was limited to vessels moored unlawfully (i.e. “without lawful authority”), which is not quite the same thing. [paras 32-33]
What was at issue in this particular case was not only what rights the claimant could establish as a matter of private law or public law, but also whether his actions amounted to the commission of an actionable wrong, either at common law or under statute, which would entitle the BWB to require the removal of the vessels. Section 8 of the Act did not confer upon the board a general power to require the removal of vessels moored without permission. The power was exercisable only in a case where the vessel was there “without lawful authority”. Although the common law did not recognise a riparian right to permanently moor, the absence of that right did not necessarily connote the commission of a wrong such as to render the mooring unlawful. It was necessary to ask whether, even in the absence of an established riparian right to moor, Mr Moore had committed any actionable wrong, either at common law or under statute, which made what he was doing unlawful. BWB had not adduced any evidence that the claimant was obstructing the public right of navigation by other members of the public, or committed any wrong to the riparian owners, or indeed any wrong as regards the canal bed of the GUC with the tidal element.
If what the claimant was doing was not a legal wrong, he was entitled to do it. If he was entitled to do it, he was not doing it “without lawful authority” within s.8, because the law allows him to do what it did not prohibit at common law or by statute.
BWB therefore had no power under the 1983 Act to require the appellant to remove his vessels. Lewison LJ pointed out that different considerations might well apply if a claim in trespass were brought against Mr Moore by the owner of the bed of the waterway over which his vessel is moored.
Mummery LJ took the opportunity to comment on the value of oral argument in a week which allowed two appeals by litigants in person. In each appeal the success was the result of oral argument which allowed the Court to focus on legal or factual arguments which had not been fully appreciated in the court below. Such “proactive judicial engagement” with the case was allowed by
talking through unfamiliar, confusing or difficult factual and legal aspects; disentangling what matters from what does not matter; bringing order and understanding to the discussion of what matters by judicial thinking aloud to test legal propositions and to double-check facts; and ensuring as far as possible that, in conjunction with the pre-reading of the papers, the court has a good grasp of what the parties are getting at.
