Final answer:
Justice Byron R. White believed that with the Roe v. Wade decision, the Supreme Court created a new constitutional right for pregnant women to have an abortion, which was not previously recognized.
Step-by-step explanation:
According to Justice Byron R. White's dissenting opinion in Roe v. Wade, the Supreme Court created a right that did not previously exist. Justice White claimed that the Court “fashions and announces a new constitutional right for pregnant women” without significant reasoning or authority. This new right was deemed strong enough to override most existing state abortion statutes, suggesting a major shift in interpretation of the Constitution regarding personal liberties and state laws.
