What was the result of Planned Parenthood v Casey?

The result of Planned Parenthood v. Casey was a landmark decision by the Supreme Court of the United States that upheld the constitutional right to abortion, while creating a new test for the constitutionality of abortion laws. The decision essentially reaffirmed Roe v. Wade, but also allowed for states to impose some restrictions on abortion, as long as they did not pose an "undue burden" on women seeking an abortion.
