Derivative Suit Dismissal Motion
Minority shareholder Destiny Davis filed a derivative suit against Dixon Foods alleging that the CEO diverted a contract to a family-owned supplier. The board appointed a special committee that interviewed witnesses, reviewed financial records, and examined the supplier relationship before concluding that continued litigation would harm the company. The court granted the motion to dismiss because the committee's process met the required standard.

Common questions
Frequently Asked
4
What must a corporation show to obtain dismissal of a derivative suit under the Model Business Corporation Act?+
The corporation must show that a qualified decision maker determined in good faith, after conducting a reasonable inquiry, that maintaining the suit is not in the corporation's best interests. The inquiry must be adequate to support the conclusions reached.
Does signing a discovery response without reviewing client records violate the certification requirement?+
Yes. An attorney must conduct a reasonable inquiry into the facts before certifying that a response is complete and correct. Relying solely on a client's unverified statement when records exist fails the standard.
When may a party properly answer a request for admission by stating lack of knowledge?+
A party may do so only after stating that a reasonable inquiry has been made and that the information known or readily obtainable is insufficient to admit or deny the matter.
What level of investigation satisfies the duty of care when an agent selects a vendor for the principal?+
The agent must review readily available public information that a person of ordinary experience using due care would examine. Failure to check widely reported news about a vendor's performance breaches that duty.
