revise provisions related to serving a subpoena in a contested case.

HB 1234 revises how subpoenas for document production must be served in contested legal cases. It requires that before serving a subpoena, the person issuing it must first provide notice and a copy to all parties involved in the case. The bill also gives hearing examiners or administrative law judges the authority to cancel or change unreasonable subpoenas, or to require the subpoenaing party to cover the reasonable costs of document production if they deny a motion to quash. This affects parties in contested cases and those seeking documents through subpoenas, changing the procedural steps for service and review.
