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 product liability case venued in South Dakota; the damages framework above decides which components enter the total.

  1. Establish the but-for path from the earnings history or, for a child, student, or homemaker, from the educational path, occupational data, or the household work performed.
  2. Draw the post-injury path from actual earnings and the work-capacity opinions, and project both paths over the applicable worklife or life expectancy with growth.
  3. Value household services from time-use data and local rates, and price future care from the life care plan with category-specific cost growth.
  4. Discount every stream to present value at a stated rate and, where there are multiple claimants, apply one documented methodology to each record.
