The Colorado Libertarian Party plans to ask the State Court of Appeals to overturn a state law that lets qualified major parties decide for themselves whether to nominate newcomers to the party, yet forbids qualified minor parties the same freedom of choice. The law says no one can be nominated by a party if he or she has not been a member for a full year. But the law also says parties eligible for a primary may shorten that time period if they wish, while parties that nominate by convention may not.
