Art. 512 Political vote

When you vote in an election that uses a secret ballot, you have the right to keep how you voted private. Nobody can force you to reveal who or what you voted for in court. This means you can refuse to answer questions about your specific vote choices, even if you're a witness in a case.

There's one exception to this rule. If you cast an illegal vote, you lose this privilege. In that situation, you can be required to disclose how you voted, since the protection only applies to legal votes cast through the normal secret ballot process.
