evidence: What does it mean to ‘codify’ Roe v. Wade? In simple terms, to codify something means to enshrine a right or a rule into a formal systematic code. It could be done through an act of Congress in the form of a federal law. Similarly, state legislatures can codify rights by enacting laws. To codify Roe for all Americans, Congress would need to pass a law that would provide the same protections that Roe did – so a law that states that women have a right to abortion without excessive government restrictions. It would be binding for all states. But here’s the twist: Despite some politicians saying that they want to "codify Roe," Congress isn’t looking to enshrine Roe in law. That’s because Roe v. Wade hasn’t been in place since 1992. The Supreme Court’s Planned Parenthood. v. Casey ruling affirmed it, but also modified it in significant ways.
