Of course it was justice, the law was evaluate, found to be unfair, deemed illegal, and the votes from mail-in letters that werent postmarked **can not be counted**.
How is that not justice? The only thing is it had **absolutely no effect on the results of the election**, that doesnt make it unfair.
> Who have been hold accountable for these illegal activity?
It wasn't an illegal **activity** it was an illegal **law**, big difference. Again the number of letters that arrive accidentally missing a postmark are virtually 0, so it has **nothing** to do with the inauguration results and the problem was resolved regardless.
> Is there a full investigation of all known election frauds?
Investigations are for crimes where there is some evidence... a law which caused a few dozen letters to get counted that shouldn't have is not a crime nor indicative of anything needing investigation unless you can show it was evidence of some foul plot.
