1. Angle could be removed from being a Director by lodging a form 304 which would not require his signiture. However the company should have a signed letter of resignation from him filed withe the corporate register. If they remaining directors can not produce this it would be hard for them to prove that he was not removed without his consent.
2. Who are the shareholders of the company. if your friend is equal share holder then he has equal legal right to the company if he is not hes has got problems.
