Heath Care Lawsuits.org has been tracking all of the lawsuits against Obamacare. Two cases have been filed because the US Supreme Court, as you know, ruled that Obamacare is a tax. Two cases are now in the courts: 1. Hotze v. Sebelius 2. Sissel v. United States Department of Health & Human Services Hotze v. Sebelius: "...this case points out that ObamaCare, a revenue-raising bill, originated in the Senate, which is unconstitutional." This case is now in the 5th Circuit Court of Appeals. http://healthcarelawsuits.org/detai...-Texas-Claims-ObamaCare-Harms-Small-Employers Sissel v. United States Department of Health & Human Services "Status: Plaintiff appealed to the D.C. Circuit Court of Apppeals on Jul. 5, 2013. Briefing completed Dec. 20, 2013. Oral argument held on May 8, 2014. The D.C. Court of Appeals issued an adverse decision. Plaintiff's petition for rehearing en banc filed on October 6, 2014. Awaiting decision." http://www.pacificlegal.org/cases/Sissel-3-1374 In summary, since Obamacare is a tax and since all tax bills must originate in the US House of Representatives according to the US Constitution, Obamacare seems to be unconstitutional since it was a Senate bill.
