All evidence must be taken in the presence of the arbitrator and all parties, except where any of the parties has waived the right to be present or is absent after due notice of the hearing.
The rules of evidence governing civil cases apply to the conduct of the arbitration hearing, except:
Any party may offer written reports of any expert witness, medical records and bills (including physiotherapy, nursing, and prescription bills), documentary evidence of loss of income, property damage repair bills or estimates, police reports concerning an accident that gave rise to the case, other bills and invoices, purchase orders, checks, written contracts, and similar documents prepared and maintained in the ordinary course of business.
The written statements of any other witness may be offered and must be received in evidence if:

The attendance of witnesses at arbitration hearings may be compelled through the issuance of subpoenas as provided in the Code of Civil Procedure, in section 1985 and elsewhere in part 4, title 3, chapters 2 and 3. It is the duty of the party requesting the subpoena to modify the form of subpoena so as to show that the appearance is before an arbitrator and to give the time and place set for the arbitration hearing.
At the discretion of the arbitrator, nonappearance of a properly subpoenaed witness may be a ground for an adjournment or continuance of the hearing.
If any witness properly served with a subpoena fails to appear at the arbitration hearing or, having appeared, refuses to be sworn or to answer, proceedings to compel compliance with the subpoena on penalty of contempt may be had before the superior court as provided in Code of Civil Procedure section 1991 for other instances of refusal to appear and answer before an officer or commissioner out of court.
For purposes of this rule, "delivery" of a document or notice may be accomplished manually, by electronic means under Code of Civil Procedure section 1010.6 and rule 2.251, or in the manner provided by Code of Civil Procedure section 1013. If service is by electronic means, the times prescribed in this rule for delivery of documents, notices, and demands are increased as provided by Code of Civil Procedure section 1010.6. If service is in the manner provided by Code of Civil Procedure section 1013, the times prescribed in this rule are increased as provided by that section.
