Well, this is certainly going to be interesting. To begin with, it will probably be at least two years before there is a new appointment given the upcoming elections and the political makeup of the Senate. During that time I suspect that we will see a number of appeals that are already in the pipeline affirmed by an evenly divided court (that is what happens with a tie). It is also likely that there will be a lot more backroom maneuvering on the court in deciding what cases to take for review given the 4-4 split.
