I have read and tried to abide by the that/which distinction as per the article at this useful site:
http://www.wsu.edu/~brians/errors/errors.html However, I find that I sometimes still have a bit of trouble in the finer examples. Sometimes I still get stumped in what seem to be basic examples. Here's one I am grappling with at the moment:
Justice Ginsburg discussed how there have been many federal court decisions, including decisions of the Court, that “have reached the merits of third-party constitutional challenges to tax benefits without mentioning the TIA.”
After reading it, the "that" just sounded weird to me, and I tried to decide with the federal court decisions were part of a set, and I supposed they were, but then I started thinking that you can regard just about anything as a member of a set.
I thought maybe someone might have some other tests or ways of understanding the that/which distinction.
Thanks!
