Leaders of the Michigan Legislature and Gov. Jennifer Granholm have been discussing possible scenarios to approve a temporary state budget and avoid a partial government shutdown when the new fiscal year starts Monday.

But it isn't clear if they will reach agreement in time to avoid an interruption of some state services.

The Republican-controlled Senate already has passed a bill that would allow a 30-day extension of the current budget structure. The legislation is pending in the Democrat-led House.

Senate Majority Leader Mike Bishop, R-Rochester, said Tuesday "there's no way" a permanent budget can be finished in less than a week. He said Granholm must realize the necessity of a continuation budget.

The Granholm administration is acknowledging a continuation budget would be needed to avoid a shutdown at this point, but has said some sort of revenue increase must be included in a budget plan before she would approve a continuation budget. The state has a projected $1.75 billion deficit for the budget year that starts next week, and Granholm says more money is needed to support public safety, health care and education.

"She needs to sign a continuation budget in good faith so that both sides have more time to respond," Bishop said. "It's in her hands."

Bishop said Granholm is "running a three-ring circus" by threatening a shutdown of government, and lawmakers have been inundated with calls from worried K-12 schools, local governments and others.

"We don't need that right now," Bishop said. "She needs to remove that pressure from the situation."

Granholm spokeswoman Liz Boyd said Tuesday that lawmakers need to do their job now rather than later.

"They want another 30 days to do what they have failed to do in seven months? We need a comprehensive solution now," Boyd said. "Delaying this decision has a cost to citizens, too."
