Key legal question
Whether the testator had capacity to make the will on 20 October 1999
Extracted holding
The testator was probably no longer capable of discernment at the relevant time, so the will was invalid.
Extracted reasoning
Testamentary capacity must be assessed concretely for the specific act. Given the severe Alzheimer-related deterioration, prior disorientation, and later medical findings, the cantonal court could conclude that general incapacity existed.
