The attitude to the political party of the public opinion and the law has changed to the antipathy to the political party, the allowance of the political party, and the legislating of the political party.
One important step to the legislating of the political party was stepped forward by introducing the proportional representation at the time of beginning of the 20th century. The assumption of this system is existence of the political party of candidacy.
Next, the system of the restriction and the promotion of the political fund brought the legislating depressed even to internal management of the political party in the latter half of the 20th century. In legislating, there are both sides of the encouragement of the political party activity and the state intervention to the political party. This state was researched as a political party national model in Germany where the initiative of the system had been applied. National rule (For instance, in the meaning that the intention of the political party is more excellent than people's intentions) by the political party has not been simply achieved. However, there is a side where the challenge of a new political party is disturbed by the power of the nation in limiting the favor of legislating to the established party.
