Jack Smith was NEVER legally appointed.

That's speculation on your part. No one knows how many conservative justices agree with Clarence.

28 U.S. Code § 533 - Investigative and other officials; appointment

The Attorney General may appoint officials—
(1) to detect and prosecute crimes against the United States;
(2) to assist in the protection of the person of the President; and [1]
(3) to assist in the protection of the person of the Attorney General.[2]
(4) to conduct such other investigations regarding official matters under the control of the Department of Justice and the Department of State as may be directed by the Attorney General.

This section does not limit the authority of departments and agencies to investigate crimes against the United States when investigative jurisdiction has been assigned by law to such departments and agencies

Looks pretty clear. Do you know how Clarence disagreed with the above?
