"In Planned Parenthood of Southeastern Pennsylvania v Casey, an important post-Roe v Wade case, the constitutionality of several provisions of a Pennsylvania lw was disputed. The impunged provisions included a requirement that a woman’s spouse be notified of her plan to terminate her pregnancy, a mandatory 240hour wait between a first consultation respecting abortion and the procedure itself, mandatory informed consent provisions and a parental consent requirement where a minor sought abortion services. In its decision in Casey, the Court abandoned the trimester framework set out in Roe v Wade, holding that the state has a legitimate interest in fetal life from the beginning of pregnancy and that this interest becomes compelling at viability. The Casey decision means that there is no longer an unqualified right to terminate a pregnancy in the first trimester and that the state may regulate the provision of abortion services throughout pregnancy, provided that the regulation does not amount to an ‘undue burden’ on women’s right to choose abortion. The question for the court in making this determination is whether the law in question ‘has the purpose or effect of placing a substantial obstacle in the path of a woman seeking an abortion of a nonviable fetus’. In the end, the Casey Court upheld all of the disputed provisions save the spousal notification requirement."
