In the case of Francis Lagrange, Allas Isidore, a man of color (plaintiff in error) vs. Pierre Chouteau Jr., the Supreme Court was asked to determine whether or not an individual could be held liable for debts incurred by another person who had assumed their name without permission. The plaintiff argued that he should not be held responsible for any debt incurred by someone else using his name because it was done without his knowledge and consent. The defendant countered that since the plaintiff's name had been used fraudulently, he should still be held accountable for any debt associated with it. After considering both arguments, the court ultimately ruled in favor of the defendant and found that even though there was no evidence linking him directly to any fraudulent activity, he could still be liable if someone else assumed his identity without authorization and created financial obligations under false pretenses.

In the case of Francis Lagrange, Allas Isidore, a man of color, plaintiff in error vs. Pierre Chouteau Jr., the dissenting opinion was that slavery is an institution which has been recognized by law and sanctioned by public opinion since time immemorial. The court argued that it would be wrong to overturn this long-standing practice without clear evidence from Congress or other legislative bodies indicating their intent to do so. Furthermore, they argued that even if such evidence existed, it should not be used retroactively against those who had acted in accordance with existing laws prior to its passage. They concluded by stating that any attempt on behalf of the courts to interfere with matters concerning slavery should only occur when there is explicit direction from Congress or other governing bodies as opposed to judicial interpretation alone.
