Supreme Court of Delaware

Yarborough, David v. Terra Taylor, DE Dept. of Corrections Commissioner

December 16, 2025

Summary

The Supreme Court of Delaware affirmed dismissal of Yarborough’s mandamus action because res judicata barred his attempt to obtain the same relief on the same grounds asserted in an earlier petition. The earlier petition had been dismissed, the dismissal was not appealed, and Yarborough did not explain why that dismissal did not preclude relitigation.
