Opportunity shall be afforded all parties to respond and present evidence on issues of fact and argument on issues of law or policy. However, each agency, upon the motion of any party, may dispose of any defense or claim:
A party to a contested case proceeding may appear in person or by counsel, or both, may be present during the giving of all evidence, may have reasonable opportunity to inspect all documentary evidence, may examine and cross-examine witnesses, may present evidence in support of the party's interest, and may have subpoenas issued to compel attendance of witnesses and production of evidence in the party's behalf.
