W. Va. Code R. § 150-1-7
Within ten (10) days from the date of service of the complaint and order as provided in Rule 6, each defendant named in the complaint shall file an answer, duly verified, and substantially in the form of Form No. 2. The Commission may shorten or extend the ten (10) day period when it deems advisable.
The Commission may require an answer to a motion for initiation of a general investigation made by the Commission, Commission Staff, or any other person.
The answer shall fully and completely advise the parties and the Commission of the nature of the defense, and shall admit or deny specifically and in detail each material allegation of the pleading answered.
If a defendant satisfies a formal complaint, it shall file a verified statement to that effect. The complainant shall have ten (10) days to file a response if the complainant disputes that the complaint has been satisfied. If the complainant does not file such a response, the Commission will then consider whether the proceeding should be dismissed.
In computing any period of time prescribed or allowed by these rules, the day of the act, event, or default from which the designated period of time begins to run shall not be included. The last day of the computed period shall be included, unless it is a Saturday, a Sunday, or a legal holiday, in which event the period runs until the end of the next day that is not a Saturday, a Sunday or a legal holiday. When calculating a period of time from the date of service of a notice or other paper, the date of service shall be the date the sender certifies in writing that he or she emailed or mailed an item by first class mail, or the date of personal service.
