They are supposed recuse if there is a conflict of interest but nobody can force them.

So, you're saying that the LAW doesn't apply to Supreme Court Justices?

I guess not.

The law does apply to Supreme Court justices, but their constitutional status is different than other Article III judges.

Inferior courts are "ordained and established" by Congress, and are subject to such terms as Congress legislates.

The Supreme Court is created by the Constitution and posesses entire the "Judicial Power of the United States".

I presume that, like both Houses of Congress, this power includes an unreviewable power to make their own rules. Certainly, a power of Congress to require recusal by simple legislation would be unconstitutional.

However, I bet that the Court could require Kagan's recusal by simple majority vote.
