(1) An answer filed by a respondent shall specifically admit, deny or explain each fact alleged in the portions of a complaint found to state a cause of action under WAC 391-45-110. A statement by a respondent that it is without knowledge of an alleged fact, shall operate as a denial. An answer shall assert any affirmative defenses that are claimed to exist.

(2) Counterclaims by a respondent against a complainant shall be filed and processed as separate cases, subject to procedures for consolidation of proceedings.

(3) Motions to amend answers shall be acted upon by the examiner, subject to the following limitations:

(a) Amendment shall be allowed whenever a motion to amend the complaint has been granted;

(b) Amendment may be allowed prior to the opening of an evidentiary hearing, subject to due process requirements;

(c) After the opening of an evidentiary hearing, amendment may only be allowed to conform the pleadings to evidence received without objection, upon motion made prior to the close of the evidentiary hearing.

(4) If a respondent fails to file a timely answer or fails to specifically deny or explain a fact alleged in the complaint, the facts alleged in the complaint shall be deemed to be admitted as true, and the respondent shall be deemed to have waived its right to a hearing as to the facts so admitted. A motion for acceptance of an answer after its due date shall only be granted for good cause.
