However well-meaning that judge was, I think it sets a dangerous precedent. It could be a slippery slope indeed if we start allowing the courts to decide who a person in their right mind can or cannot leave their money to.
Before anybody accuses me of being racist, let me say that while I am white, I actually do have the proverbial "black friends." In fact, I have a black sister-in-law and a black nephew (by marriage) and several mixed race nieces and nephews. They are treated by all exactly as any other member of the family, as they should be.
My problem with this ruling is that the court is poking its nose in where it has no business. As long as the deceased was in their right mind and not under undue influence when their will was made, it should be honored regardless of how odious their intentions or motivations are to others. If some court can decide that a particular individual or group doesn't deserve what someone else wants to give them, it opens the door for the government to suppress any group it finds distasteful. Or as in this case, it can give a decedent's assets to someone they clearly did not want to leave anything to.
Public policy against discrimination is one thing. But to interfere with a person's last wishes because they held unpopular, politically incorrect, or yes, even racist views is quite another. It represents an unwarranted and dangerous intrusion in a person's private life. The only exception I feel would be justified would be if the bequest would go to a person or organization engaged in outright criminal activities or advocating actual violence against others.
To be clear: I think the person who made the will was a jerk and a racist and not worthy of any decent person's time or respect. But the principle of self-determination should outweigh the fact that his hateful attitude unjustly disinherits his daughter in this instance. I think the will should be upheld, but the other daughter should then share the inheritance with her sister out of a sense of fairness. That way, it would be a matter of free will and not a matter of judicial political correctness.
