What must a director do within 7 days to avoid liability for the actions of other directors?

To avoid liability for the actions of other directors, a director must formally dissent from a decision made by the board. This formal dissent serves as an official record that the director does not agree with the action taken, which can help protect them from being held responsible for decisions or actions they did not support. By providing a clear and documented expression of disagreement, the director demonstrates their non-participation in the decision-making process, thereby distancing themselves from potential liabilities that may arise from that action.

The other options do not adequately provide for the same level of legal protection. Seeking approval from shareholders does not address the need for a director to express dissent in a timely manner. Resigning from the board may sever ties with the company's decisions but does not formally protect the director from past liabilities. Notifying the company of concerns is important for internal governance but, unless formally recorded as a dissent, it may not carry the same weight in a legal context.
