JEFFERSON CITY, Mo. -- A group trying to restrict eminent domain is challenging the secretary of state's decision that two proposed constitutional amendments didn't get enough signatures to make the November ballot. The secretary of state's office announced last week that the eminent domain ballot measure and a separate petition seeking to require the use of more renewable energy hadn't gotten enough signatures to qualify for the ballot. Friday was the deadline for challenging the secretary of state's certification of ballot measures. Ron Calzone, leader of the eminent domain group, said that the secretary of state's office wrongly invalidated some of the signatures collected.
