#15: No Exclamations of Personal Opinions
Members of the British royal family are required to follow a strict protocol that limits their personal expression, including opinions. This means that members of the royal family are not allowed to express any personal opinions on political or social issues, either publicly or privately.

This does not mean, however, that the family is not allowed to be passionate about certain issues or causes. They are free to support and advocate for issues that are important to them as long as they do not express any personal opinions that could be seen as divisive or controversial.
