See
Bellotti v.
Baird, 428 U. S. 132, 147 (1976)
(Bellotti I) (State may not “impose undue burdens upon a minor capable of giving an informed consent.” In
Bellotti I, the Court left open the question whether a judicial hearing would unduly burden the
Roe right of an adult woman. See 428 U. S., at 147);
Bellotti v.
Baird, 443 U. S. 622, 640 (1979)
(Bellotti II) *462(opinion of Powell, J.) (State may not “unduly burden the right to seek an abortion”);
Harris v.
McRae, 448 U. S. 297, 314 (1980) (“The doctrine of
Roe v.
Wade, the Court held in
Maher, 'protects the woman from unduly burdensome interference with her freedom to decide whether to terminate her pregnancy,’ [432 U. S.], at 473-474, such as the severe criminal sanctions at issue in
Roe v.
Wade, supra, or the absolute requirement of spousal consent for an abortion challenged in
Planned Parenthood of Central Missouri v. Danforth, 428 U. S. 52”);
Beal v.
Doe, 432 U. S. 438, 446 (1977) (The state interest in protecting potential human life “does not, at least until approximately the third trimester, become sufficiently compelling to justify unduly burdensome state interference . . .”);
Carey v.
Population Services International, 431 U. S. 678, 705 (1977) (Powell, J., concurring in part and concurring in judgment) (“In my view,
[Roe and
Griswold v.
Connecticut, 381 U. S. 479 (1965),] make clear that the [com--pelling state interest] standard has been invoked only when the state regulation entirely frustrates or heavily burdens the exercise of constitutional rights in this area. See
Bellotti v.
Baird, 428 U. S. 132, 147 (1976)”). Even though the Court did not explicitly use the “unduly burdensome” standard in evaluating the informed-consent requirement in
Planned Parenthood of Central Missouri v.
Danforth, supra, the informed-consent requirement for first-trimester abortions in
Danforth was upheld because it did not “unduly burde[n] the right to seek an abortion.”
Bellotti I, supra, at 147.
