When it was written it was legal. It was in the constitution. Thus constitutional. If it said that slavery was illegal but some state allowed it anyway, that would be wrong. And that’s what happening today with the 2A.Article I, Section 2, Clause 3 allowed slavery in the original writing of the Constitution. Later, a judge, a group of Judges said nope.
Which is right and wrong.
