PENSACOLA, Fla. – Twenty states and the nation's most influential small business lobby demanded Friday that a federal court in Florida hear their challenge to President Barack Obama's health care overhaul because they face imminent harm from its mandates.

The Justice Department in June asked a federal judge to dismiss their lawsuit, saying the U.S. District Court in Pensacola lacks subject-matter jurisdiction over some of the lawsuit's claims. They also said other parts of the lawsuit failed to state claims upon which relief can be granted.

The states, the National Federation of Independent Business and several individual taxpayers filed their response Friday in Pensacola federal court.
A key issue raised by their lawsuit is whether the federal government can require individuals to purchase health care insurance and fine those who don't.

"If Congress can regulate the failure to have health care insurance coverage, it can equally regulate the 'failure' to meet any other requirement it chooses to impose," Florida Attorney General Bill McCollum wrote in the response.

Though the health care mandate does not take effect until 2014, the states will suffer now from spending more resources on an expanding Medicaid enrollment and from losing sovereignty "to enact statutes or state constitutional provisions to protect their state citizens from compulsion in their healthcare choices," McCollum wrote.

Obama's health insurance requirements also would impose significant costs on small businesses, he said.

The court must hear the case to preserve individual liberties granted through the Constitution, said Karen Harned, executive director of the Small Business Legal Center of the National Federation of Independent Business.

"The federal government does not have the authority to regulate an individual's decision to do nothing. If they did, then they could force us to purchase any product they want," she said.

In a statement, Harned said the government's motion to dismiss was based on "political rhetoric and flimsy legal arguments" and was an attempt to distract the court from evaluating the case's constitutional issues.

An attorney for the Justice Department referred calls to an agency spokesman, who did not immediately return a phone message.

McCollum, a Republican candidate for governor, is leading the legal challenge. Other states that have joined the lawsuit are Alabama, Alaska, Arizona, Colorado, Georgia, Indiana, Idaho, Louisiana, Michigan, Mississippi, Nebraska, Nevada, North Dakota, Pennsylvania, South Carolina, South Dakota, Texas, Utah and Washington.

Virginia's attorney general separately sued the government. A federal judge denied the Justice Department's motion to have that case dismissed, saying the overhaul raises complex constitutional issues.

Missouri voters on Tuesday overwhelmingly voted in favor of a state measure to bar the government from requiring people to carry health insurance and penalizing those who don't.

In its motion to dismiss the lawsuit filed in Florida, the Justice Department said the requirement to buy coverage is an exercise of Congress' constitutional power to tax and spend. Government attorneys also have said that while reasonable people may disagree on issues such as the health care overhaul, it cannot be moved from the elected branches of government into the courts without a genuine constitutional issue, which they maintain is absent in this case.

U.S. District Judge Roger Vinson has set a Sept. 14 hearing to consider arguments on the motion to dismiss.

The states argue the new law will require them to pay additional Medicaid costs not covered by the federal government, but that they cannot opt out of the program for low-income and disabled people because it has become too popular.

They maintain that violates the 10th Amendment, which says the states and people have powers that the constitution does not grant to the federal government nor prohibit the states from having.

"I'm really, really really perturbed right now about the intrusion of the federal government in the rights of my state," McCollum told reporters in Orlando. He said it was part of a pattern also seen in Arizona where the Justice Department has challenged a new immigration law.

The health care law, passed along partisan lines, requires most Americans to carry health insurance — through an employer, a government program, or by buying their own policy. Insurers will then be required to take all applicants, and the government will offer tax credits to help middle-class households pay premiums. Medicaid will be expanded to cover millions more low-income people.

Individuals who refuse to get health insurance will face a tax penalty, with exceptions for financial hardship and religious reasons.
