This is going to have to be brief.
I was on the phone with my brother, the lawyer, about an hour ago. The question we were debating was: how can a non-corporate group of persons come to attain rights as a group (e.g. a couple or a family).
WE do often speak of parents' rights, though I think the right way to understand the term, "parents' rights" is as follows: "parents' rights" are those rights, which individuals hold ceteris paribus, who are the parents of children.
More on the issue, including significant background, either later on or tomorrow.
