[4CJ]

I note you don't post the DATE of Miller v. US, 78 Wall. 268 - it was heard in the December 1870 term with the decision released 3 Apr 1871. Prior Supreme Court decisions - prior to the war - held that uncompensated takings were unconstitutional.

[Non-Sequitur]

Prior to that there hadn't been a rebellion. Legislation was passed to combat the rebellion. The matter was taken to court and the court ruled that the Constitution hadn't been violated. That's the way it works, regardless of the date of the ruling.
