“Today’s decision gives considerable momentum to our health-care reform efforts here in Maryland,” O’Malley (D) said in a statement jointly issued with Lt. Gov. Anthony G. Brown. “What it does not — and indeed must not — do, is give us license to take our eye off the ball or slow our progress. Moms, dads, and kids throughout Maryland are counting on their elected leaders to continue the mission of lowering costs, and improving the quality of care. We remain as committed as ever to moving forward on behalf of our families.”

Under O’Malley’s tenure, Maryland has been one of the more aggressive states in implementing the provisions of the federal law.

Update, 1:30 p.m.:

Maryland House Minority Leader Anthony J. O’Donnell (R-Calvert) has told reporters that while he is disappointed in the Supreme Court ruling, he respects it. Carrying out the federal health-care law in Maryland could add to state’s project budget shortfalls, O’Donnell warned. “Maryland will be forced to raise taxes at state level, again,” he said.
