<P> Planned Parenthood v. Casey , 505 U.S. 833 ( 1992 ) , was a landmark United States Supreme Court case in which the constitutionality of several Pennsylvania state statutory provisions regarding abortion was challenged . The Court 's plurality opinion reaffirmed the central holding of Roe v. Wade stating that `` matters , involving the most intimate and personal choices a person may make in a lifetime , choices central to personal dignity and autonomy , are central to the liberty protected by the Fourteenth Amendment . '' The Court 's plurality opinion upheld the constitutional right to have an abortion while altering the standard for analyzing restrictions on that right , crafting the `` undue burden '' standard for abortion restrictions . Planned Parenthood v. Casey differs from Roe , however , because under Roe the state could not regulate abortions in the first trimester whereas under Planned Parenthood v. Casey the state can regulate abortions in the first trimester , or any point before the point of viability , and beyond as long as that regulation does not pose an undue burden on an abortion . Applying this new standard of review , the Court upheld four regulations and invalidated the requirement of spousal notification . </P>
