With the legislature’s inaction last month, more than $500 million in cuts to education and other planned spending are scheduled to take effect July 1 — a result that O’Malley said on Friday cannot stand.

“There is too much at stake not to move forward,” O’Malley said. “I’m confident that we can come together with the Senate President and House Speaker to complete this most important work for the people of our State.”

The largest components of the leftover business include an income tax increase for those making more than $100,000 and the first step in a plan to shift responsibility for teacher pension costs from the state to Maryland counties.

Though some details remained to be worked out, Democratic leaders of both the House and Senate have signed off on the scope of the special session.

Republicans have said that there is no need to return to Annapolis, arguing that the state is able to absorb the cuts in planned spending.
