Case Against Johnny Depp For Alleged Iggy Pop Show Assault Dismissed

TMZ broke the story ... a woman named Robin Eckert sued Depp back in April -- claiming Depp's bodyguards assaulted her at an Iggy Pop concert last year, then dragged her along the ground ... causing her pants to be removed from her body and "exposing her buttocks."

Robin filed the lawsuit anonymously -- under the name "Jane Doe" -- though it's unclear why ... because she provided her name when she filed a police report back in December.

Now a judge has dismissed the case -- finding Robin had no justification for filing anonymously. According to the judge, Robin can refile -- but only if she sues under her legal name.
