The Supreme Court has ruled that opening political party primaries to all members in good standing may not completely eradicate vote buying but will significantly reduce opportunities for targeted financial inducements during internal elections. The ruling formed part of the Court's landmark 5–2 decision declaring the delegate system used by political parties to elect presidential and parliamentary candidates unconstitutional. The Court subsequently ordered all political parties to adopt systems that allow every member in good standing to vote directly in internal primaries. "True, opening party primaries to every party member is no guarantee that money politics will disappear. However, it ruled that decisions, appointments and actions lawfully taken under the delegate system before the judgment remain valid and cannot be invalidated solely because of the ruling.
