Louis Brandeis, Armour Company v. Ft. Morgan Steamship Company…
“ The original contract was referred to, also, to explain the relation of the shipper named in the bill of lading to the charterer, and in order to establish that by reason of their co-operation in converting the vessel into a cattle ship there was no liability. Such uses of nonmaritime contracts to establish the absence of a valid maritime claim, or a defense as distinguished from a counterclaim [1] (see The Eclipse, 10 S.C.t. 873, 135 U.S. 599, 609, 34 L. Ed. 269) , do not deprive the admiralty court of jurisdiction. ”
