Contrary to what you may believe Supreme Court Justices are not appointed for life, they are appointed to serve during periods of good behavior.
The decisions made by the Supreme Court are not laws, they are merely thepersonal opinions of 9 unelected and unaccountable partisan politicians.
For over 200 years the Court has made some horredous decisons, but only 1 Justice was ever impeached and he was not not removed from offrice.
Chief Justice Roger B. Taney and his Associate Justices should have been impeched when they issue the infamous Dred Scott decision. In 1896 the the Court ruled 7 to 1 that segregation did not violate the Constitution,
In 1944 in Koramatsu v United States the Court ruled 6 to 3 that the internment of Japanese American and the theft of their property did not violate the Constitution. The six Justices should have been impeached.
