Were there any Texans on that court, or was this a court packed with Reconstruction-era judges less than a generation after the Civil War?
To be blunt, this ruling has no more power than a ruling by the House of Lords in 1776.
Five justices were nominated by Lincoln during Civil War (probably replacing Southerners who left the Court when their States seceded); three were nominated in the 1845-47 timeframe. While it was a 5-3 decision, two of the dissenters were Lincoln appointees.
The case is still precedent; it has not been overruled.
Justices were from Ohio (2), and one each from New York, Pennsylvania, New Hampshire, Kentucky, Virgina, and Illinois. One of the Ohio Justices also served on the California Supreme Court.
