The status of parties is established in the political practices of parties,reflecting the relationships among party—country—society.After the World War II,regulating the status of parties by laws is the common practice of different countries.But different countries have different ideas about parties,so the laws on parties are different in detail and form.In accordance to the legal standard of "legal and illegal","support and exclusion",the legal status of parties can be summed up as four cases such as positive recognition of general parties,prohibition all or particular party and confirming the advantage status of a particular party,restrictions or exclusion of small party.Comparing the legal status of parties in Great Britain,the United States,Russia,and Germany,it can be summed up as four cases such as negative,more negative,more positive and the most positive.Fundamentally speaking,the political validity of party politics is more fundamental than the legitimacy.
