In the case of Tayloe v. T. & S. Sandiford, a dispute arose between two parties over an unpaid debt and whether or not it was secured by a mortgage on real estate owned by one of the parties. The defendant argued that they had paid off the debt in full, while the plaintiff contended that only part of it had been paid and that there remained an outstanding balance due to them which was secured by a mortgage on property owned by the defendant. After hearing both sides' arguments, the Supreme Court ruled in favor of plaintiff and held that there indeed existed an outstanding balance due to them from defendant which was secured by a mortgage on their property as alleged in their complaint. Furthermore, they ordered for this amount to be collected from said mortgaged property if necessary so as to satisfy any remaining debts owed to plaintiff party

In Tayloe v. T. & S. Sandiford, Chief Justice Marshall delivered a dissenting opinion in which he argued that the court should not have dismissed the case on technical grounds without considering its merits. He noted that it was an action of assumpsit brought by William Tayloe against Thomas and Samuel Sandiford for money due under a contract between them, and that the defendant had pleaded non-assumpsit to this action as well as several other pleas which were overruled by the court below but not discussed in their judgment or opinion. The Chief Justice believed these pleas should be considered before dismissing the case because they raised important questions about whether there was any legal obligation between parties to fulfill contractual obligations when one party has already performed his part of it while another has failed to do so; if such an obligation exists then justice requires that it be enforced regardless of technicalities or procedural rules barring consideration of certain matters at trial. In conclusion, he stated “I think we ought not to dismiss this cause until we have examined all those points” and thus would reverse the decision made by lower courts with instructions for further proceedings according to law
