The Delaware Court of Chancery on Monday dismissed three consolidated derivative suits against Tesla after concluding that the company's Texas forum-selection bylaw was enforceable—even though plaintiffs filed their complaints before the bylaw became effective.

Vice Chancellor David's opinion in In re Tesla, Inc. Derivative Litigation, C.A. No. 2024-0631-BWD, turns on a tight set of facts: Tesla publicly announced the Texas forum bylaw before any of the suits were filed in May and June 2024, and the bylaw became effective days later, before defendants appeared and before any meaningful litigation took place.

Tesla stockholders subsequently approved the company's redomestication to Texas and the forum bylaw by a 63% vote. The court gave that vote significant weight. "The owners of the corporation voted to require that derivative litigation be filed in a Texas forum," Vice Chancellor David wrote. "On the present facts, it is not inequitable to enforce their decision."

The court rejected plaintiffs' argument that filing first in Delaware gave them a vested right to litigate there. Under Delaware law, forum-selection clauses receive maximum effect absent a fundamentally inequitable result or conflict with positive law. The opinion found neither condition met here. Filing a complaint, the court reasoned, does not "perfect" a right to a particular forum when defendants later appear and invoke a valid bylaw.

The retroactive-enforcement holding rested heavily on timing. "The argument for enforcement here is even stronger than in those other cases because the Texas Forum Bylaw was publicly announced before these actions were initiated and became effective just days later, before the defendants appeared and any meaningful litigation occurred," the court wrote.

The ruling carries practical implications for redomestication transactions and litigation planning. Companies that adopt stockholder-approved forum-selection bylaws before defendants appear in pending suits may be able to redirect derivative claims to their chosen forum. For plaintiffs' firms, the window to lock in a Delaware forum narrows considerably if a bylaw can take effect between filing and first appearance.

The decision does not address whether the result would differ if substantial litigation had occurred before the bylaw's effective date, or if the bylaw had not been disclosed before filing. Those fact patterns remain open.
