Under 1905.25(a)(1), when may a witness's testimony be taken by deposition in an OSHA hearing?
Yes — a witness's testimony may be taken by deposition when the witness is unavailable or for other good cause shown. The rule permits depositions to be taken orally or by written interrogatories before any person designated by the presiding hearing examiner who has authority to administer oaths, as explained in 1905.25(a)(1).
