A proxy battle on Obamacare - Massachusetts health care providers sued the Bay State government for denying rate increases and argued before a judge that they will "go out of business" without the hikes. The attorney representing the Bay State countered that Beacon Hill has the power to control insurance rates and, further, the court had no jurisdiction in the case. In the meantime, all but a couple of insurance companies have refused to accept new customers. The judge is expected to make a decision Monday.
