- Why don't I pitch in here... so far nobody has really answered his question.
- Science, in regards to scientific theory, uses empirical evidence; nothing else will do. Science absolutely requires evidence which can be tested many times by many people. Personal testimony does not suffice, because people can be biased, lying, or just plain mistaken.
- Judicial evidence can be empirical, certainly, but we (as in the court system) also rely upon personal testimony. I'm not a large fan of this system, myself, but it is probably the best thing available at the time.
- As for a link with 'official' rules of evidence for the courts... I am at a loss, I'm afraid.
