Primaries
Primaries were not established in law until January 2010, when they were added to the Constitution as an option for political parties to choose candidates to any directly elected post. The Constitution states that the primary results are legally binding for political parties that submit to them and that the losing candidates are ineligible for the same election in the respective office.
Primaries will be an option once the specific law regulating them is approved.
