On October 8, 2009, a U.S. District Court in Rhode Island had struck down a Central Falls city ordinance that made it illegal for a voter to sign petitions for two candidates running against each other for the same office. The city had appealed to the First Circuit. But on November 3, 2010, the First Circuit said the city’s appeal is moot. This is partly because the Rhode Island legislature passed a law in 2010 that requires all towns to let voters sign as many petitions as they wish. Fontes v City of Central Falls, 09-2516.
Even before the case started, it had already been the law in Rhode Island that voters could sign as many petitions (for the same office) for federal and state office as they wished. The case only arose because some towns in Rhode Island had a more restrictive policy.
