The supreme court justices involved in the matter were appointed as follows. The letter 'M' signifies majority or consenting opinion. The 'D' is dissenting:
Renquist - D (appointed by Nixon - Rep)
Powell - M (appointed by Nixon - Rep)
Blackmun - M (appointed by Nixon - Rep)
White - D (appointed by Kennedy - Dem)
Burger - M (appointed by Nixon - Rep)
Brennan - M (appointed by Eisenhower - Rep)
Douglas - M (appointed by FDR - Dem)
Stewart - M (appointed by Eisenhower - Rep)
Marshall - M (appointed by Johnson - Dem)
As you can see, 6 of the 9 justices on the court in 1973 were appointed by Republicans. One of the two dissenting opinions were Democrats. So the next time someone brings up this case pointing to liberal R v W judges, tell them 5 of 7 in the majority were Republican appointees.
Also, the scope of the decision was limited up to viability of the fetus.
