Funny, it doesn't say that here:
"The Privilege of the Writ of Habeas Corpus shall not be suspended, unless when in Cases of Rebellion or Invasion the public Safety may require it."
As to your fictive motive, of restraining corrupt judges, the Federalist is likewise silent.
Please produce your documentary evidence that "the Suspension Clause was written with a corrupt judge like Taney in mind."
I don't know why I bothered to look, since the burden was yours, and your normative aura of inventive fiction rises like steam from the post. Like your invocation of Farber's oil of slippery elm in your steaming #1690.
