The Office of Campaign and Political Finance has issued a statement on the Citizens United decision by the Supreme Court and how it relates to our chapter 55 section 8. The Globe has an analysis here. See our original post here.
In addition, there were changes to local campaign finance laws that went into effect in January. Chapter 28 of the acts of 2009 amended the campaign finance laws, the open meetings laws and the lobbying restrictions. The Office has an overview of how the law is applied in a variety of elections in their newsletter.
And, as always check our pages on Elections and Open Meetings.
