Corporate Director Removal and Board-Vacancy Requirements in South Dakota

At a glance

Requirements one by one

S.D. Codified Laws § 47-1A-101 names the South Dakota Business Corporation Act.

Removal defaults to with or without cause

S.D. Codified Laws § 47-1A-808 permits shareholders to remove one or more directors with or without cause. The articles may make cause exclusive. A director elected by a shareholder voting group may be removed only through that group's participation.

At a quorate meeting, S.D. Codified Laws § 47-1A-725 ordinarily requires votes favoring removal to exceed votes opposing it. S.D. Codified Laws § 47-1A-727 permits the articles to impose a greater quorum or vote. South Dakota's statutory cumulative voting rule adds the separate protection below.

Cumulative votes can preserve a seat

S.D. Codified Laws § 47-1A-728 gives shareholders cumulative voting without an articles opt-in. Section 47-1A-808 therefore prevents removal when the votes cast against it would be sufficient to elect the director cumulatively. The statute does not limit that protection to a partial-board removal or create a separate classified-board cause rule.

Judicial removal uses a two-part merits test

The cited provisions state no general board-removal or automatic- disqualification route. Under S.D. Codified Laws § 47-1A-809, a proceeding by or in the right of the corporation must establish fraudulent conduct, gross abuse of the director position, or intentional corporate harm. The court must also consider the course of conduct and inadequate alternatives and find removal in the corporation's best interest. It may prescribe a reelection bar and other equitable relief.

Removal is meeting-only despite the general consent rule

S.D. Codified Laws § 47-1A-808 expressly limits shareholder removal to a meeting called for that purpose and requires the meeting notice to identify removal as a purpose. That specific rule does not permit the general unanimous written- consent route in § 47-1A-704 to substitute for the removal meeting.

S.D. Codified Laws § 47-1A-705 generally requires 10-to-60-day shareholder- meeting notice. Under § 47-1A-702, the board or an articles- or bylaw-authorized person may call a special meeting. Holders of at least ten percent of votes on the proposed issue may demand one; the articles may lower that percentage or raise it no higher than twenty-five percent.

Resignation is written and may use a later date

Under S.D. Codified Laws § 47-1A-807, a director delivers written notice to the board, its chair, or the corporation. The resignation is effective on delivery unless it specifies a later date. The section states no future-event, acceptance, withdrawal, conditional failed-election, or irrevocability rule.

Three ordinary fillers share the vacancy power

Unless the articles provide otherwise, S.D. Codified Laws § 47-1A-810 permits shareholders or the board to fill a vacancy. When remaining directors are below quorum, an affirmative majority of all directors remaining in office may fill it. If shareholders fill a seat originally elected by a voting group, only that group may vote; the section states no parallel requirement that a board filler come from directors elected by that group.

A specific later vacancy may be filled early, but the successor cannot take office until the vacancy occurs. Under S.D. Codified Laws § 47-1A-805, any vacancy replacement's term expires at the next shareholder meeting at which directors are elected, followed by holdover until a successor is elected and qualifies. That next-election term applies even though § 47-1A-806 allows two- or three-group staggered boards.

What trips people up

Filling a class-elected seat is asymmetric

S.D. Codified Laws § 47-1A-810 expressly reserves a shareholder-filled vacancy to the voting group that elected the former director. It does not repeat that restriction for a board-filled vacancy. The articles may alter the default and must be checked before assuming the same electorate limitation governs both routes.

Shrinking the board does not cut short an incumbent term

S.D. Codified Laws § 47-1A-805 says a decrease in the number of directors does not shorten an incumbent director's term. A board-size amendment is not the statutory substitute for the removal procedure.

Common questions

Can shareholders fill a vacancy when every director seat is empty?

Yes. Section 47-1A-810 gives shareholders a default filling power, and § 47-1A-702 permits qualifying holders to demand a special meeting when no board is available to call one. The governing articles and meeting-demand percentage still control.

May a replacement begin serving before a future resignation takes effect?

No. Section 47-1A-810 allows early selection for a vacancy scheduled at a specific later date, but the new director may not take office until the vacancy actually occurs.
