South Dakota courts and expert standards

South Dakota courts screen expert testimony for reliability: the trial judge asks whether the economist is qualified, whether the opinion rests on sufficient facts and reliable principles and methods, and whether those methods were reliably applied to the case. A damages report is written to that standard, with each data series named and each assumption tied to the record.

Where these cases are heard

Highest court: South Dakota Supreme Court. Federal venues: D.S.D. Court system: ujs.sd.gov.

Outside the civil courts, wage-loss disputes in workers' compensation matters proceed before the South Dakota Department of Labor and Regulation, Division of Labor and Management.

Damages framework

South Dakota provides a wrongful death action for the pecuniary injury to the surviving spouse, children, or next of kin, which the courts read to include loss of companionship and society, alongside a survival action for the estate. The state's unusual comparative negligence rule allows recovery only when the plaintiff's negligence was slight in comparison with the defendant's, the common-law collateral source rule applies, and prejudgment interest is allowed on past damages but not on future damages, punitive damages, or intangible losses.

How the analysis is built

The same four steps apply to a motor vehicle accident case venued in South Dakota; the damages framework above decides which components enter the total.

  1. Document the earnings history, the date the person left work, and any return to work at full or reduced capacity.
  2. Project the but-for earnings over a worklife expectancy with a stated wage growth rate and compare it with the post-injury path.
  3. Value fringe benefits from plan documents or published employer cost data, household services from time-use data, and future care from the life care plan.
  4. Discount each stream to present value at a stated rate and present the alternative scenarios where the return-to-work date or capacity is disputed.
