To me, "human" is a member of the human race, "person" is any creature with consciousness, feelings, personality. So, if an ape/dolphin/alien/robot/whatever is intelligent enough, they are a person to me.

This is my opinion, though a lot of it was shaped by the German education system, so it's definitely possible that when this question becomes actually relevant in a decade or two that a judge might rule this the official interpretation.
