Final answer:
The Full Faith and Credit Clause of the U.S. Constitution mandates that a judgment obtained in Virginia must be recognized and enforceable in California, ensuring judgments are respected across state lines subject to jurisdiction and due process.
Step-by-step explanation:
The clause that provides that a Virginia judgment can be upheld or enforced in California is the Full Faith and Credit Clause of the United States Constitution. This clause, found in Article IV, Section 1, requires that "Full Faith and Credit shall be given in each State to the public Acts, Records, and judicial Proceedings of every other State." Accordingly, a judgment rendered in a Virginia court will generally be recognized and enforceable in California, provided that the original court had proper jurisdiction and the judgment was obtained in a manner consistent with due process.
