(a) In an appeal under AS 43.05.405, discovery may take place only under a plan for discovery approved by the administrative law judge. The administrative law judge shall approve a plan for discovery to the extent consistent with the efficient, just, and speedy conduct of the appeal. The plan may limit or set conditions on discovery and must include provisions for stipulations of fact by the Department of Revenue and the taxpayer. Discovery shall be limited to information that is relevant to the determination of the correct tax or penalty, unless the Department of Revenue or the taxpayer makes a showing that the discovery is reasonably calculated to lead to admissible information.
(b) Requests by the taxpayer for disclosure of public records relating to the appeal are governed by, and the records are disclosed only in accordance with, the plan approved under this section.
(c) Legislative history, reported court decisions, statutes, regulations, or similar documents available for public inspection at a library or the office of the lieutenant governor or through a publicly accessible database must be obtained through those means and may not be sought through discovery.
