From the meeting of president-elect and the swearing in ceremony....
He was absent for that visit, but I
think he recused himself from a case.
I could be wrong tho.
The Exxon case also raised one side issue an increasingly sore point among Supreme Court practitioners: the problem of justices recusing themselves from cases, usually because of stock-holdings.
Justice Samuel Alito recused himself in the Exxon case (the justices do not state their reasons when they do so) and, as a result, one of the issues the Court had planned to decide in this case whether federal maritime law permits punitive damages to be awarded against a corporate defendant solely based upon the reckless conduct of a managerial employee resulted in a 4-4 tie vote.
In such cases, the lower courts ruling stands, but has no precedential weight.
