William Monson v. White Bear Mitsubishi, and Western National Insurance Co.

Summary

The Supreme Court of Minnesota reviewed the denial of a petition to vacate a workers' compensation settlement award. The court held that the medical records and settlement agreement established a prima facie showing of sufficient cause based on newly discovered evidence and mistake concerning the extent of the employee's disability, reversed the denial, and remanded for a hearing.

Holdings

1. A workers' compensation award, including an award based on a negotiated settlement, may be vacated when facts developing after the award or previously unknown facts establish substantial additional disability or a genuine mistake concerning the nature and severity of the injury.
2. The Workers' Compensation Court of Appeals abused its discretion by denying the petition because the medical records and settlement agreement made a prima facie showing of cause sufficient to justify reopening the award.

Questions Presented

1. Whether the workers' compensation settlement award could be reopened based on newly developed facts and medical evidence showing that Monson's spinal fusion had failed and that his disability was substantially greater than understood at the time of settlement.
2. Whether the medical records and settlement agreement established sufficient cause under Minn. Stat. § 176.461 to vacate the award for mutual mistake of fact, newly discovered evidence, or substantial change in medical condition.
3. Whether the Workers' Compensation Court of Appeals abused its discretion by denying Monson's petition to vacate the award.
