"The woman's consent. Under § 3(2) of the Act, a woman, prior to submitting to an abortion during the first 12 weeks of pregnancy, must certify in writing her consent to the procedure and "that her consent is informed and freely given, and is not the result of coercion." Appellants argue that this requirement is violative of Roe v. Wade,410 U.S. at 410 U. S. 164-165, by imposing an extra layer and burden of regulation on the abortion decision. See Doe v. Bolton, 410 U.S. at 410 U. S. 195-200. Appellants also claim that the provision is overbroad and vague."
