even over a sister?
The granddaughter had more ties to the grandmother than just blood. She apparently had finacial resposibilities as well. and Proximity plays a large part in determining guardianship and legal resposinbility. The court could very well hold it's original ruling that the granddaughter has guardianship, but stipulate that end of life decisions must be agreed upon by the sister and the brother.
Let me explain, generally you sisters and brothers go on to make thier own households with thier own decendants, the granddaughter is a direct decendant of the grandmother, which makes her closer in consanguinity (that means blood relation) than the sister. The reason why the Georgia code is written that way is because at the time that the particular code was added it was rare for an adult granddchild to make decisions for a grandparent. Life expectancy has changed. The granddaughter did nothing wrong in exercising her right to care for her grandmother. We might disagree with what she chose, but she had that right. the brother and sister have the right to protest, which is what they did. I still think there are facts that we are unaware of in this case that have not been brought to light.
