A. 
No fine shall be levied under § 263-70 and no indemnity shall be assessed under § 263-74 except upon due hearing regarding the violation permitting the alleged violator to show cause, if any there be, before the approving authority why a fine should not be imposed pursuant to § 263-70 or why assessment should not be made pursuant to § 263-74 or any combination of the two. An order for hearing issued by the approving authority shall be served upon the alleged violator in the same manner as a summons is served under Wisconsin Statutes, and it shall be returnable before the approving authority at a time certain not sooner than five days after service.

Testimony taken before the approving authority will be under oath or affirmation and recorded stenographically. A transcript thereof will be made available to any member of the public, including, but not limited to, any party to the hearing, upon payment of the usual charges therefor.
D. 
After the approving authority has reviewed the evidence, it may impose any fine authorized by § 263-70 or assess any indemnity authorized by § 263-74, as in the judgement of the approving authority, is warranted by the evidence. The approving authority may issue such further orders and directives as it deems appropriate, including orders requiring the violator to pay the full costs of the proceedings, including the approving authority's technical, administrative, and other costs in developing its proofs and reasonable attorneys' fees.
E. 
A violator may avoid the hearing herein provided by written waiver stipulating guilt presented to the approving authority at least 24 hours prior to the hearing time. The approving authority will meet nevertheless, will make no stenographic transcript, will give the violator an opportunity to be heard in mitigation.
