WAC 230-17-110. Documentary evidence

(1) When requested for cause, the presiding officer may: (a) Require that parties submit all documentary evidence to the other parties sufficiently in advance so that they may study and prepare cross-examination and rebuttal evidence. (b) Reject documentary evidence not submitted in advance if the party offering it cannot show that there was good cause for failing to submit it sooner. (2) Unless a party files a written objection before the hearing, the authenticity of all documents submitted in advance is accepted. Parties may later file a challenge of authenticity if they show good cause for failing to file a written objection.
