I don't think excluding her would have changed the results but it certainly would have removed an appearance of conflict of interest. But to me the very fact that Cinquanta dismisses the issue so cavalierly is indicative of the institutional culture that is a problem.
You have a small pool of judges. You need to put into place processes that do the most given that constraint to limit the appearance of conflict of interest and excessive insider relations. You won't be able to do that to everyone's satisfaction but I think some effort in that direction would help improve the ISU's credibility.
