"Other courts that have considered the parental consent issue in the light of Roe and Doe, have concluded that a statute like § 3(4) does not withstand constitutional scrutiny. See, e.g., Poe v. Gerstein, 517 F.2d at 792; Wolfe v. Schroering, 388 F.Supp. at 636-637; Doe v. Rampton, 366 F. Supp. at 193, 199; State v. Koome, 84 Wash. 2d 901, 530 P.2d 260 (1975). We agree with appellants and with the courts whose decisions have just been cited that the State may not impose a blanket provision, such as § 3(4), requiring the consent of a parent or person in loco parentis as a condition for abortion of an unmarried minor during the first 12 weeks of her pregnancy. Just as with the requirement of consent from the spouse, so here, the State does not have the constitutional authority to give a third party an absolute, and possibly arbitrary, veto over the decision of the physician and his patient to terminate the patient's pregnancy, regardless of the reason for withholding the consent. Constitutional rights do not mature and come into being magically only when one attains the state-defined age of majority. Minors, as well as adults, are protected by the Constitution, and possess constitutional rights. See, e.g., Breed v. Jones, 421 U. S. 519 (1975); Goss v. Lopez, 419 U. S. 565 (1975); Tinker v. Des Moines School Dist., 393 U. S. 503 (1969); In re Gault, 387 U. S. 1 (1967). The Court indeed, however, long has recognized that the State has somewhat broader authority to regulate the activities of children than of adults."
