Wyo. Stat. Ann. § 40-12-107

The enforcing authority may accept written assurance of voluntary compliance with respect to any practice believed to be violative of W.S. 40-12-105 from any person who is engaged or is about to engage in such practice. Such assurance is not considered an admission of violation for any purpose. Proof of failure to comply with the assurance of voluntary compliance is prima facie evidence of a violation of this act. Matters closed by virtue of the acceptance of an assurance of voluntary compliance may at any time be reopened by the enforcing authority for further proceedings in the public interest, pursuant to W.S. 40-12-106.
