Not even the Supreme Court could declare slavery to be legal.
Not to worry. Terri will soon be dead and cremated, and everyone on FR can go back to praising the president
Yes they could, if they decided to. In this hypothetical scenario of judiciary abuse, would the President or the Congress be Constitutionally able to overrule or reverse such a gross violation of the Constitution? Well if so, then they have the power to overrule ANYTHING a judge rules that blatantly violates a person's Constitutional rights.
And Terri Schiavo is being starved to death by judicial order even though several doctors have declared she is not in a PVS. (One of those doctors was on a team appointed by the Court). Her civil and religious rights are being trampled on and most folks know that, (though some diehard partyline people will never admit it).
