Keila A. Rodriguez Alvarez, Below v. William E. Castellon, Below

Summary

The Supreme Court of Delaware affirmed summary judgment enforcing a general release signed after an automobile accident. It held that the undisputed facts showed no mutual mistake about the existence of Rodriguez’s injuries because she knew she had continuing back and neck pain when she executed the release, and her later-diagnosed injuries were related to the original trauma rather than materially different injuries. The release’s clear and unambiguous language therefore controlled.
