You forgot to mention what it is that you "may not have a leg to stand on"...
Are you quoting a state law? or a federal law? Here, in California, I am facing a similar decision soon. But I am trying to find an attorney group for help.
Abood v. Detroit Board of Ed. was a federal case.
"leg to stand on" was a mere colloquialism .
Interesting...and supposedly the remedy is to go find an organization that you agree with and send your portion to that org.
It's a logistics nightmare, IMO, much akin to the United Way Myth that says you can direct your donation to a particular group.
