The states are often described, in the memorable words of Justice Louis Brandeis, as the “laboratories of democracy,” places in which new laws and practices can be tested and perfected on the local level before spreading to the rest of the nation. Unfortunately, this process can occasionally go awry, as it did with Massachusetts’ recent anti-corruption law. Modeled after the vague and excessively broad federal “honest services fraud” statute, the Massachusetts law ended up criminalizing vast swaths of ordinary political activity.

The first test case pursued by Massachusetts Attorney General Martha Coakley was a prosecution of former state Treasurer Timothy Cahill. In light of the jury’s acquittal of the co-defendant and its hung verdict in Cahill’s case, my latest column, which ran in this weekend’s Wall Street Journal, takes a look at the anti-corruption law and the alleged “criminal” activity that Cahill engaged in while making a third-party bid for governor in 2010.

After realizing that nobody writing about or reporting on the prosecution of former Massachusetts treasurer Timothy Cahill nor his co-defendant Scott Campbell seemed to grasp the fundamental reasons that the prosecution was both unlawful and ill-considered as a matter of sound public policy, I decided to write a short piece on the case for The Boston Globe. (The Globe’s news and editorial pages were a prime example of what I view as a wrong-headed view of the case – cheering on the prosecution despite its violating the Due Process of Law rights of the defendants as well as the public’s right to benefit from public officials’ exercise of their informing function. And so I submitted my piece to the Globe, which, admirably, agreed to run it despite it’s being critical of the paper.)
