You're corrected - sorry you are wrong - as indicated by the number of Circuit Court Judges that were (and are) being fillibustered in the Senate - i.e. Brent Kavanaugh - currently still stuck in the Senate vortex awaiting confirmation to the DC Court of Appeals.

Also, a little digging found that 2 chief justices of the supreme court and 6 assoc. justices were recess appointed.
But then I also found something saying 16 judges have been recess appointed to the supreme court, but it didn't provide any names.
So, in conclusion, judges can be recess appointed. Even to the Supreme Court.
Here is a snip...
Presidents have recess-appointed more than 300 federal judges, including 15 Supreme Court justices. The practice is as venerable as George Washington, who named John Rutledge chief justice in this way.
Where'd ya go?
