Right-to-Lifers hoping the restrictive abortion bill just approved by the Louisiana Legislature will lead to the overturning of Roe v. Wade are likely to be disappointed, legal experts say. If, as expected, Gov. Buddy Roemer lets the measure become law, prochoicers plan a quick appeal that would probably reach the Supreme Court. By a 5-4 vote, the justices recently rejected a Minnesota law requiring both parents be notified before a minor has an abortion. Court watchers say it's unlikely Justice Sandra Day O'Connor, the pivot vote in that case, would accept the more restrictive Louisiana law.
