Noted.
Not so sure on this one.
This is incorrect. The Tax Act of 1862 only repealed the income tax sections (Sections 49, 50, and 51) of the Revenue Act of 1861. Not the entire thing.
The income tax at that time was a wartime tax and temporary.
According to Wikipedia, the act which expired was the
Revenue Act of 1864 which expired in 1873.
Revenue Act of 1861 or Act of August 5, 1861, Chap. XLV, 12 Stat. 292
Revenue Act of 1862 or Act of July 1, 1862, Ch, 119, 12 Stat. 432
I'll review the Pollock decision, but I don't believe it says what you are claiming.
I'll respond later with some dicta from early Supreme Court cases concerning taxation including Springer v. U.S. and Pollock.
