After all these years, rear-end car accidents still produce new law. Here, the court of appeals held that evidence of Medicaid benefits were properly excluded by the collateral source rule. Under CRS 10-1-135, any collateral source payment is excluded from evidence. Medicaid payments are a collateral source, and the statute abrogated the common law “gratuitous government benefits exception.” Plaintiffs’ claims against ANS, the company insuring the car, were dismissed; thus, ANS as the prevailing party was entitled to costs but not fees because the claims were not frivolous. The remaining issues got short shrift: 1) the sudden emergency doctrine has been abolished; 2) a party who requests a hearing on costs is entitled to one; 3) Plaintiffs were awarded appellate fees because Defendants frivolously argued for a new trial under CRCP 59 based on a requirement that did not exist.
