On July 15, the Minnesota Supreme Court agreed to hear Paquin v Mack, A101177. The issue is the validity of the petition of the Warriors for Justice Party. The party submitted a petition to qualify two candidates for the legislature. The candidates needed 500 valid signatures. They had enough, except that the county clerk disallowed all signatures in which the signers showed a post office box address instead of a residence address. See this story.
The signatures were collected on an American Indian reservation in Beltrami County. In a similar case in 2008, the Arizona Supreme Court upheld the validity of such signatures, in Jenkins v Hale, 190 P 3d 175. Like the current Minnesota case, the Arizona case involved an Indian reservation, where many dwellings don’t have formal residence addresses. Thanks to Bill Van Allen for the link.
