There is not.
I read CB's post and I thought it raised a good point.
However, I think her answer should have been something like this:
"I dealt with the then hotly-contested constitutional issue of what is required in the districting of City Council seats, including the issue of whether or not proportional representation was required. As a Council Member, I worked to make sure that we met the requirements of the Constitution, but also tried to make sure that we did not unnecessarily wade into litigation and use scarce City resources to fight a lawsuit."
That would have been a good answer. And it would be a good position for a council member to take. But to imply or state the PR is required is wrong.
