Last month, we wrote that a few US Supreme Court justices had to recuse themselves from a case because they held stock in companies with a matter before the court.

Justice Samuel Alito, for instance, holds shares in Bristol-Myers Squibb. And earlier, Chief Justice John Roberts sat out a case involving lawsuits against Pfizer because his May 2007 financial disclosure form indicated he held Pfizer stock between $10,000 and $50,000.

We noted this because the court this fall will review a preemption case involving Wyeth, and the court’s ruling will determine whether patients can sue a drugmaker through state law when a product has already been approved by the FDA. As noted many times, this is an important issue for pharma.

And so we ran a poll in which most of you believe the justices should recuse themselves. Now, their latest disclosure statements indicate that Roberts sold all his shares in Merck and three other companies last year, and Alito reduced his holdings in Bristol-Myers Squibb, among other sales, the Associated Press reports.

We’ll keep you posted any other relevant holdings or disclosures that occur.
