In re = “in the matter of”, a legal term != “re:”, regarding/reply

I'm sorry, but I don't see how that difference is material to the HN title.

Because the title has "In re".

The article's title exceeds HN's 80 char limit and so had to be shortened.

"Litigation" can be shortened to "Litig."

[fixed typo and HN does not accept trailing dot in URL]

"Litigation" can be shortned to "Litig."

We don't do abbreviations like that in HN titles. I even want to say we never do that, though never is a strong word.
