Question:

What general rule about marriage validity did the De Leon v. Perry court reaffirm?

Answer:
The court reaffirmed the principle that a marriage valid where contracted is valid everywhere, and a marriage void where contracted is void everywhere.

Explanation:
This is a long-standing rule of conflict of laws. It emphasizes that the law of the place where the marriage is celebrated (i.e., the lex loci celebrationis) governs its validity. This promotes predictability and consistency across jurisdictions in recognizing marriages.
