This case involved the steamboat Planter, which was seized by William L. Howard and Francois Varion in 1831 for alleged piracy. Sylvan Peyroux and others, who claimed ownership of the vessel, appealed to the Supreme Court on grounds that they had not committed any act of piracy or other illegal activity. The court found in favor of Howard and Varion because they were able to prove that Peyroux et al had indeed been engaged in piratical activities prior to their seizure of the boat. Furthermore, it was determined that even if there had been no evidence of such activities at the time when Planter was taken into custody, its owners would still have lost title due to their failure to register it with a proper authority as required by law. This decision established an important precedent regarding maritime law: vessels must be properly registered before being allowed out onto open waters or else risk forfeiture should they become subject to legal action later on down the line.

In the case of Sylvan Peyroux and Others, Claimants of Steamboat Planter v. William L. Howard and Francois Varion, Libellants, the dissenting opinion argued that a vessel owner should not be held liable for damages caused by an independent contractor’s negligence in operating their vessel. The majority had ruled that since the owners were aware of the negligent operation they could be held responsible for any resulting damage to another ship or property; however, Justice McLean disagreed with this ruling on two grounds: firstly because it was impossible to prove whether or not they knew about such negligence before it occurred; secondly because he believed that holding them liable would create too much uncertainty in maritime commerce as well as encourage contractors to act recklessly without fear of consequence due to being indemnified by their employers. He concluded his dissent stating “the law ought never impose upon individuals obligations which cannot be enforced” thus arguing against imposing liability on those who are unaware of potential risks associated with contracting out services related to vessels.
