The City of Birmingham has lost the court fight to keep the Cooper Green Mercy hospital open for the poor. The city was unable to force Jefferson County in the latest round in court Wednesday to keep hospital open and operating as usual. Lawsuits against the county are effectively frozen in place until the county emerges from bankruptcy under Chapter 9. The city asked U.S. Bankruptcy Judge Thomas Bennett to lift a stay so the city could sue the county in state court. The county commission voted in August to close the inpatient unit and emergency room at the county owned hospital.
