Louis Brandeis, Luckenbach v. McCahan — Opinion of the Court
“ The shipper is under no obligation to the carrier to take out insurance on the cargo; and the freight rate is the same whether he does or does not insure. The general law does not give the carrier, upon payment of the shipper's claim, a right by subrogation against the insurers. The insurer has, on the other hand, by the general law, a right of subrogation against the carrier. Such claims, like tangible salvage, are elements which enter into the calculations of actuaries in fixing insurance rates ”
