Here's a good example of a quasi-Streisand effect as applied to precedent.
The studio that owns the rights to the movie The Fall are, like many studios, tired of people pirating the thing. So they decide to catch some people and sue them. They hop on BitTorrent and quickly find some people sharing the thing, and log their IP addresses.
Normally, in situations like this, you just file a John Doe complaint, subpoena the internet provider, get the actual names, and then replace the John Does with the actual defendant and go to town. But the DCMA also contains a more streamlined subpoena process that allows copyright holders to skip the whole "file a lawsuit" part and obtain a quick subpoena by filling out a form, and the statute says the court clerk "shall" issue the subpoena if it's done properly. No need to even involve (or have to convince) a judge or anything like.
The studio discovers that 29 of the (alleged) pirates have IP addresses with Cox, so fills out the forms and asks the federal court for a streamlined DCMA subpoena to Cox that discovers the identities of the alleged pirates. Cox forwards that subpoena (as the DCMA requires) to those 29 people, and -- predictably -- none of them do anything about it.
Except for one.
One guy -- John Doe -- writes a letter back to the Court saying, essentially, "Oops, I'm not a pirate, it's just I didn't put a password on my WiFi. Problem solved now. Never downloaded that movie. Must have been someone else using my WiFi. Please don't tell them my name." The district court interprets that letter as a request to quash the subpoena to John Doe, and asks the studio to respond.
Now, at this point, if I'm the lawyer for the studio, here's what I'd do: Nothing. You've already got the names of 28 alleged pirates -- Cox gave you those already when those 28 never responded. Go to town and sue all 28 of them (or whatever subset you feel like) to make your point. Leave Mr. Active -- John Doe -- out of it.
Sure, we all know he's probably a pirate too, but who cares? Having 28 defendants is as good for your purposes as 29. Probably even better, since the 29th ill probably be a little more pain in the ass than Mr. 29, who got off his duff and bothered to write a letter in response to the subpoena.
But, no, the studio here spends the money to write a whole big motion saying that the subpoena to Cox is valid, the DCMA allows it, blah blah blah. Spending far more money, I'm certain, than a rental of The Fall would possibly cost, as well as more than you're ever going to get from Mr. 29 anyway, since most of the guys I know who pirate movies don't exactly have $150,000 in statutory copyright damages lying around in their couch cushions.
Plus, even that assumes you first win the subpoena motion, and then prevail in your copyright suit against his "no password" defense. And, here, the studio doesn't even get to that latter point, and loses on the first. The district court holds that an internet provider -- Cox -- isn't subject to the expedited DCMA subpeona process because they're just providing the tubes, not actually holding copies of the movie itself.
Now, at this point, if I'm the studio, here's what I am going to yet again do: Nothing. Leave it be.
It's a Hawaii district court opinion. An unpublished one, at that. Who cares? Let it go. Dominate the defenseless other 28 defendants, make your point, and move on.
But nope. The studio appeals. Spending more time and money trying to get approval for the subpoena for Mr. 29.
Leading to today, at which the Ninth Circuit holds -- in a published opinion -- that, yep, you can't use the streamlined DCMA subpoena process to get subpoena ISPs like Cox.
So, before, you could issue a subpoena, get one entered, get virtually every name you wanted, but you might not get the name of that incredibly rare person who actually bothered to file an objection.
But now, after your appeal, in binding precedent, you -- and the other studio like you -- are categorically precluded as a matter of law from doing so to the 67 million residents of the Ninth Circuit. As well as all of the ISPs in that area, and I assure you, there are quite a few.
Not a sound strategic decision.
But yay for Mr. Doe. Well done. Pirates everywhere owe you a debt of gratitude.
And to personally commemorate this august opinion, and in honor of the Streisand effect, this weekend, I'm definitely not going to watch Fall -- which actually seems like it could potentially be a cool movie -- on a pirate website.
And neither should you.
