If I may add something, often it's a group that will go to court. They are a group; they have resources; they have a board and they can make decisions, but, ultimately, the decisions that they gain from the courts are applicable to individuals.
In the language rights world, a sizable number of cases revolve around education. Often you have parent associations that will speak for school boards and they will go to court so that children will have access to an education of equal quality, etc. The school boards have the right to make decisions as to who does and who doesn't get into, in this case, a francophone school.
With all these decisions, albeit spearheaded by groups such as parent associations or groups of that ilk, the ultimate goal is to get decisions that will have an impact on individual parents or individual children. So the vehicle to get a court decision is often a group, but the impact goes beyond the group that is going to court.
