“How a company's constitution interacts with the Companies Act”
If your company has a constitution, you, the company, the board, and all directors and shareholders still have to follow the rules in the Companies Act 1993. However, your company’s constitution can change some of these rules. It can say that certain rules don’t apply or work differently for your company. But the constitution can only do this if the Companies Act 1993 allows it. So, the Act is still important, but your company’s constitution can make some changes to how the Act works for your company.
