Importantly, this fiction only preserves rights of action in rem and not contractual rights or obligations per se. If, for example, a contractual breach gives rise to a claim attracting admiralty jurisdiction, it would be incumbent on the claimant to commence an action in rem and thereby crystallise his statutory lien. He delays doing so at his peril, for a statutory lien that has not been so crystallised is defeasible by a subsequent change in the vessel’s ownership. If, however, the statutory lien is crystallised timeously, then the action will proceed and notwithstanding a judicial sale, the action will continue against the sale proceeds standing in the actual vessel’s stead. Different practical considerations arise where maritime liens and possessory liens are concerned, but the legal fiction operates, in essence, to preserve such interests in the same manner. Thus, properly understood, the legal fiction has nothing to say about whether contractual claims underpinning a prospective statutory lien can survive the judicial sale of the relevant vessel.
