Let’s say you expect boards in general to be 50% male/female.

In case where this is not the case, and where it has not been the case for a number of years you might launch an investigation.

It might be that there are reasonable reasons in this instance. For example, the company was cofounded by two women or men, it’s a small company, and the composition of the board has never changed etc.

It might be that the company has a board with frequently changing members, but always selects male members. In that case, it’s easier to argue that discrimination has taken place. At which point you might launch an investigation and apply penalties etc.
