The Democratic-controlled U.S. House of Representatives and 20 Democratic-led states asked the Supreme Court on Friday to declare that the landmark Obamacare healthcare law does not violate the U.S. Constitution as lower courts have found in a lawsuit brought by Republican-led states.

Axar.az reports citing Reuters that the House and the states, including New York and California, want the Supreme Court to hear their appeals of a Dec. 18 ruling by the New Orleans-based 5th U.S. Circuit Court of Appeals that deemed the 2010 law’s “individual mandate” that required people to obtain health insurance unconstitutional.

The petitions asked the Supreme Court, which has a 5-4 conservative majority, to hear the case quickly and issue a definitive ruling on the law, formally called the Affordable Care Act, by the end of June.
