Therefore, it is crucial to bring witnesses to the hearing who can testify about what they observed and/or what their opinions are concerning the issues in the hearing. ALJs may not base a decision on “hearsay” alone, but must have some other evidence to support the decision. [5 C.C.R. Sec. 3082(b).] Most documents are considered hearsay if a witness is not present to identify or testify about them.
