On the HealthCare.gov website, you can read the complete, certified version of the Affordable Care Act (Obamacare) as passed by Congress and then signed into law by the President on March 23, 2010, as well as the Supreme Court's June 28, 2012 decision upholding the constitutionality of the law.
HelathCare.gov provides a convenient, section-by-section summary of the law, as well as downloadable .pdf versions of:
Full Text of the Affordable Care Act and the Reconciliation Act;
Certified Full-Text Version of the Affordable Care Act; and
Certified Full-Text Version of the Reconciliation Act
Note: The Reconciliation Act contains amendments and technical corrections to the Affordable Care Act agreed to by both the House and Senate. The Reconciliation Act was signed by President Obama on March 30, 2012, just seven days after he signed the Affordable Care Act.
