Sherman Minton,
Lewis v. United States (348 U.S. 419…
“ If petitioner desires to engage in an unlawful business, he does so only on his own volition. The fact that he may elect to pay the tax and make the prescribed disclosures required by the Act is a matter of his choice. There is nothing compulsory about it, and, consequently, there is nothing violative of the Fifth Amendment. If he does not pay the occupational tax, proceeds to accept wagers, and is prosecuted therefor, as in this case, he cannot be compelled to testify and may claim his privilege. ”
