Mississippi is asking the Supreme Court to overrule Roe v. Wade in order to uphold the state’s restrictions on abortion access, and to renounce the court’s landmark holding a half-century ago that the Constitution protects a woman’s right to obtain an abortion.

The state’s bold request is in a brief filed Thursday that seeks to persuade the court it should approve a law that would ban most abortions after 15 weeks of pregnancy, far earlier than now allowed.
