408.406—How do we evaluate the evidence you give us?
When you give us evidence, we examine it to see if it is convincing evidence. This means that unless we have information in our records that raises a doubt about the evidence, other evidence of the same fact will not be needed. If the evidence you give us is not convincing by itself, we may ask you for additional evidence. In evaluating whether the evidence you give us is convincing, we consider such things as whether:
(a)
The information contained in the evidence was given by a person in a position to know the facts;
(c)
The information in the evidence was given under oath, or with witnesses present, or with the knowledge that there was a penalty for giving false information;
(f)
The information contained in the evidence agrees with other available evidence including our records.
