Stack ranking is irrelevant to all that and doesn't solve that "problem". If you want to protect yourself from lawsuits, just have a documented policy for evaluation/incentives with a papertrail showing you adhere to it and your decisions. Stack Ranking can have a poor papertrail too. Consider how you would respond to: "This ranking board was all men, and all the women were ranked low. Why?" That's when you want something more substantive behind the ratings.
