an ultimately unsuccessful attempt to attract the seceding states back into the Union and to entice border slave states to stay. Five states ratified the amendment in the early 1860s, but none have since. To become part of the Constitution today, ratification by an additional 33 states would be required. The subject of this proposal was subsequently addressed by the 1865 Thirteenth Amendment, which abolished slavery. The Child Labor Amendment (proposed 1924) would, if ratified, specifically authorize Congress to limit, regulate and prohibit labor of persons less than eighteen years of age. The amendment was proposed in response to Supreme Court rulings in Hammer v. Dagenhart (1918) and Bailey v. Drexel Furniture Co. (1922) that found federal laws regulating and taxing goods produced by employees under the ages of 14 and 16 unconstitutional. When submitted to the states, ratification by 36 states was required for it to become part of the Constitution, as there were forty-eight states. Twenty-eight had ratified the amendment by early 1937, but none have done so since. To become part of the Constitution today, ratification by an additional ten would be required. A federal statute approved June 25, 1938, regulated the employment of those under 16 or 18 years of age in interstate commerce. The Supreme Court, by unanimous vote in United States v. Darby Lumber Co. (1941), found this law constitutional, effectively overturning Hammer v. Dagenhart. As a result of this development, the movement pushing for the amendment concluded. No longer pending The Equal Rights Amendment (proposed 1972) would have prohibited deprivation of equality of rights (discrimination) by the federal or state governments on account of sex. A seven-year ratification time limit was initially placed on the amendment, but as the deadline approached, Congress granted a three-year extension. Thirty-five states ratified the proposed amendment prior to the original deadline, three short of the number required for it to be implemented (five of them later voted to rescind their ratification). No further states ratified the amendment within the extended deadline. In 2017, Nevada became the first state to ratify the ERA after the expiration of both deadlines, followed by Illinois in 2018, and Virginia in 2020, purportedly bringing the number of ratifications to 38. However, experts and advocates have acknowledged legal uncertainty about the consequences of these ratifications, due to the expired deadlines and the five states' purported revocations.
