This research is a normative legal research using statute and case approach, with juridical qualitative approach. The data were collected through library research by reading and analyzing the books, scientific journals, legal document, and non-documents related to the issue. The result of research shows that the ex-convicted has the right to be candidate in the regional election based on Article 28D Paragraph (3) of the 1945 Constitution and Article 43 Paragraph (1) of Law No. 39 of 1999 on Human Rights and also based on the Constitutional Court Decision No. 42/PUU/XIII/2015.
