Willard v. Tayloe, 75 U.S. (8 Wall.) 557 (1869), was a decision by the Supreme Court of the United States that courts of equity deciding issues of contract have discretion to determine the form of relief based on the circumstances of each individual case. The Court established a new rule to determine the form of relief: Relief should serve the ends of justice, and should be withheld if it appears likely to produce hardship or injustice to either party.
