"A deal backed by Mayor Dave Bing and Michigan Gov. Rick Snyder, a Republican, would grant the city the power to void contracts and slash costs but not provide state funding or loans to bail the city out of its financial problems.<quoted text>
Without city council agreement on that deal, Snyder can by law appoint an "emergency manager" who will assume the powers of the mayor and council to run day-to-day operations. He has until Thursday to take such action."
you see the words "by law" and the city council could have avoided the entire "takeover".
