Final answer:
Justice Rehnquist wrote a dissenting opinion arguing against the protection of a right to privacy in the case of abortion in Roe v. Wade.
Step-by-step explanation:
The dissenting opinion arguing against the protection of a right to privacy specifically in the case of abortion was written by Justice Rehnquist. In the landmark case Roe v. Wade, the Supreme Court established a woman's right to an abortion as part of a constitutional right to privacy. This decision has since become one of the most controversial modern Supreme Court decisions. Notably, it was using the 9th Amendment and the 14th Amendment as its basis, which has been at the center of a divisive fight between “pro-choice” and “pro-life” sides of the social and legal debate.
Justice Rehnquist was among the two dissenting justices who voted against Roe in the decision, which was a 7-2 split. He contested the use of the right to privacy implied in the Constitution to support the legalization of abortions, effectively opposing the majority's grounding of abortion rights within the right to privacy framework.
