I can't parse this title. Which is the verb?
"DOJ v Google evidence release" is a noun phrase.
If you wanted to rewrite it as a sentence and weren't constrained by conventions used in headlines, you could rewrite it as, "Evidence released in DOJ v Google case includes an exhibit that the Judge called embarrassing [for Google]"
Even now it doesn't really make sense. This PDF is not an "evidence release", it is either evidence or a statement about released evidence. Unless that is a term of art in law?
an exhibit, in this context, is a piece of evidence
this one was embarrassing for google
"DOJ vs Google evidence releases, which evidence judge calls embarrassing"
