You never know. Even the liberal judges believe the opinion in Roe V Wade showed a certain lack of comprehension of historical facts by the judge who wrote it. It is regarded as very poorly worded and very poorly tought out. O'Connor or one of the other justices may change their mind. The conservatives have enough votes to hear the case, but probably not enough to overturn it so they may be even more reluctant to accept the case than the liberals.
So, conservative judicial activism that overturns long-standing precedence on closing cases in a timely manner is a good thing?
Hoo boy. Better get ready for a BUNCH of lawyers to shout "MULLIGAN!" and re-litigate a bunch of moldy cases.
The danger is that the court does revisit the case and actually toughens the Roe V Wade arguement and decision!
