Is amputation incumbent if the stolen item is found diminished in value, and it is unknown whether the diminution occurred at the time of theft or afterward?

Primary text

If the item is found diminished in value, and it is unknown whether it was deficient at the time of theft or the deficiency occurred later, amputation is not incumbent. This is because the obligation is not established when there is doubt concerning one of its conditions, and the default presumption is non-obligation.
