Finnish Pirate Party now officially registered
The party was founded in May 2008. The delay of registering it as an entity allowed to nominate candidates can mostly be explained by activists having to go through the trouble of collecting 5,000 manually signed singatures on paper cards before being able to apply for recognition as this type of organization.
