Kan. Admin. Regs. § 27-3-12
All hearings shall be conducted informally and in such manner as to ascertain all the facts and the full rights of the parties. The appellant and any third party may present such evidence as may be pertinent to the issues involved. The director may receive any evidence logically tending to prove or disprove a given fact in issue, including hearsay evidence and irrespective of common law rules of evidence. Where a party appears in person, the director may examine such party and his witnesses, if any, to such extent as the director deems necessary. During the hearing, the director may, with or without notice to any of the parties, take such additional evidence as the director deems necessary, provided, however, that the appellant is afforded the opportunity to respond to such submissions or evidence.
