Non-Compete Enforcement Litigation in South Dakota

An educational explainer on how non-compete enforcement cases resolve in South Dakota courts — the deadlines, the venue rules, and the strategy you can war-game as a simulation.

South Dakota courts

Where this case gets filed

South Dakota's trial court of general jurisdiction is the Circuit Court, organized into seven judicial circuits that together cover the state's 66 counties. Circuit Courts hear the full range of civil litigation, from contract and tort claims through complex commercial disputes, with a case typically filed in the circuit encompassing the county where venue is proper. Magistrate judges sitting within each circuit handle small claims and other limited civil matters.

Civil actions are generally filed in the county where the defendant resides or, for corporate defendants, where the defendant has its principal place of business, or where the cause of action arose.

The claims

What the two sides are actually fighting over

Breach of Restrictive Covenant

  • A valid, enforceable non-compete agreement existed (adequate consideration, reasonable scope, duration, and geography)
  • The covenant protects a legitimate business interest
  • The former employee breached the covenant's restrictions
  • The breach caused harm or threatens irreparable harm to the former employer

Tortious Interference with Contract

  • A valid restrictive covenant existed between the plaintiff and the former employee
  • The new employer knew of the covenant
  • The new employer intentionally induced or facilitated its breach
  • Damages resulted from the interference
Damages & fault

How South Dakota apportions fault and damages

South Dakota follows an unusual 'slight-gross' comparative negligence standard: a plaintiff may recover only if their negligence was slight and the defendant's was gross by comparison, rather than applying a simple percentage-based bar. Juries weigh the parties' relative fault under this framework. Punitive damages are available in appropriate cases but are subject to judicial review for excessiveness rather than a fixed statutory cap.

Strategic dynamics

Enforceability is a jurisdiction-driven threshold question, so choice-of-law and forum-selection fights frequently precede any discussion of reasonableness on the merits — a covenant enforceable as drafted in one forum may be voided or narrowed in another. The preliminary injunction hearing functions as the case's fulcrum much as in trade secret disputes, since a court's early read on irreparable harm typically previews how it will ultimately view the covenant's reasonableness. Blue-penciling discretion adds another layer of uncertainty: even a facially overbroad covenant may survive in narrowed form, which keeps settlement value in play even when the original restriction looks unenforceable on its face.

In Juricratic

How this area is war-gamed

  • Model scope, duration, and geography as independent reasonableness dials feeding a single enforceability finding, rather than one blended severity score.
  • Branch the choice-of-law question as a threshold node, since the same covenant can resolve differently depending on which jurisdiction's enforcement posture governs.
  • Simulate blue-pencil reformation as a distinct outcome path separate from full enforcement or full voiding, showing the narrowed-covenant middle ground.
  • Run the tortious interference claim against the new employer as a linked but separately provable branch, since its outcome does not automatically follow the primary breach claim.
