A number of legal experts and even some more recent Supreme Court justices have said that Justice Harry Blackmun’s opinion was on very shaky constitutional grounds.
The original ruling has already been partially altered by the 1992 decision in Planned Parenthood v. Casey. A lot of the original protections included in Roe v. Wade were discarded.
A decision that either upholds or reverses Roe v. Wade is going to cause an uproar and calls on Congress to take legislative action of one sort or another, which is ridiculous because Congress does not have any constitutional authority to legislate abortion, even if one stretches the Commerce Clause way beyond its limits.
It’s long past time for the Supreme Court to reimpose the original limits on the powers of Congress to regulate. Ever since Wickard v. Filburn in 1942, the definition of interstate commerce has become more and more elastic.
Removing the federal government from the abortion issue is a good place to start.
