Maine cannot enforce a law voters approved two years ago that limits what foreign governments can spend on campaigning in state and local elections, following a federal appeals court decision Friday.

A Maine voter-approved law barring companies with stakes held by foreign government from spending on state elections runs afoul of the First Amendment, a panel of First Circuit judges held.

The Maine Supreme Judicial Court affirmed on Friday that the language of an upcoming statewide referendum question on whether to require photo identification in order to vote does not need to change.
