It's been a year since Gov. Rick Snyder signed Michigan's Public Act 4 of 2011, officially known as the Local Government and School District Fiscal Accountability Act.

The law upgraded the powers afforded emergency managers under Public Act 101 of 1988 and Public Act 72 of 1990, both passed to give the state some rights over governmental bodies facing bankruptcy. Public Act 4 increased the ability of the governor to intervene, and granted appointed emergency managers the power to break collective bargaining agreements, fire elected officials and privatize or sell public assets.

The governor argues desperate times call for drastic measures. "For too long in this state, we've avoided making the tough decisions," Snyder said when he signed the law on March 16, 2011.

A year later, four cities and two school districts are under emergency management. Inkster officials recently opted for a consent agreement with the state to avoid a full takeover. Likewise, pressure is mounting for the city of Detroit to consent to a state-backed financial restructuring plan or face an emergency manager by the end of the month.

Its critics charge Public Act 4 circumvents democracy, instating officials with complete power and no accountability to the residents of the communities they control. Others worry the emergency managers' mandate to focus on fiscal matters trumps all other concerns, like curricula in school districts and public services in cities.

And as the number of sitting emergency managers grows, pushback against Synder and state Treasurer Andy Dillon has increased, too.

The Detroit-based Sugar Law Center is backing 28 citizens in a lawsuit alleging Public Act 4 violates the state constitution. Snyder asked the state Supreme Court to fast-track a decision on the case, but the court has yet to decided whether to do so.

Meanwhile Detroit Rep. John Conyers, a Democrat, is seeking federal intervention. In December, he asked U.S. Attorney General Eric Holder to investigate the law.

And on Feb. 29, organizers with a coalition called Stand Up For Democracy turned in 50 boxes of petitions to the Secretary of State in favor of freezing the Public Act 4 and putting it up for referendum on the November ballot.
