In a recent post Mark Pulliam has nicely observed that the amendment process itself makes the Constitution a living document, capable of responding to new circumstances. But defenders of living constitutionalism as an interpretive theory do have a response to this position. They have argued that the amendment process is just too stringent and must be supplemented by judicial updating. Mike Rappaport and I have provided two interrelated arguments about why these theorists are wrong, thus bolstering Mark’s position.
First, the amendment process does not seem too hard, if we look at the six amendments that came closest to becoming law—those that obtained passage in Congress by 2/3 majorities but foundered in the state ratification process. Most of these amendments were not good ones and the most consequential would have made slavery legal and even entrenched that position against subsequent constitutional amendment.
It is true that most people today would favor the amendment banning child labor which passed Congress, but did not succeed at the ratification stage. But we argue that the amendment ultimately failed because Franklin Roosevelt decided not to push it: the amendment was too narrow an expansion of federal power for his purposes of centralized economic control.
