Yes and no. Suppose I want to take a stab at automating Westlaw. Now I need to download all of the court opinions ever so that I can put them in my database and use them to train my machine learning algorithm. Can I actually get them for any reasonable price? All of them? And without doing something that will get me charged with unauthorized access to a computer like Aaron? Because if not, fixing that is a legitimate goal. (And if so, do post the link.)
So very close to "everything."[1] Why don't you ask Google to put up a torrent?
[1] Anything that isn't in there is probably on a library shelf somewhere, and you're welcome to do the same thing Lexis/Westlaw did and scan it in yourself.
Certainly it will be great to have free access to the data in bulk, and that day will come. But from a practical perspective, the barrier to entry as a businessperson in this space is not data. There is enough data at https://bulk.resource.org/courts.gov/ to experiment with. And if your experiments work, there are companies that will sell you access to all the data.
Heck, that's pretty much where Lexis and West came from so long ago, but now technology is offering the possibility (at least in theory) to democratize the process so that someone can screw around with the data over a weekend or three and see if they can create something worth following up before they go through the trouble of looking for funding in order to buy data.
I don't know if we're even particularly arguing about anything. Is there really an argument to be made that this data should not be freely available? If "that day will come" then I guess all I'm saying is that sooner is better than later.
My only point was that providing open access to cases so that individuals can learn the law is a solved problem via Google Scholar. Bulk access is not a problem for individuals. I say this as someone who has worked to create better legal research tools for nearly 5 years: the first 2 on a startup that failed, the next 1 at Scholar, and the last 1.5 on a new startup that I believe will finally succeed.
So while the desire to open up PACER - and the attention given to it - is great, I don't think it will have any effect on the future of individual access to law, or to the future of innovation and business in the legal space. I don't think lack of innovation today has anything to do with lack of bulk access today. I think the deficiencies are more a reflection of the fact that innovation in this space is really hard.
Basically: The opinion access problem is not "largely solved". If it was, Google wouldn't be one of the folks fighting to get access to opinions, and I wouldn't be funding folks like Carl Malamud to do things like scan federal reporters (https://yeswescan.org/index.court.html, #22).
If your interest is in getting and providing bulk access to cases, then yes, you have obstacles. But that is only a problem for a select few individuals/companies who care about this as a business or hobby. The end users you may be trying to service by offering access to the cases can already get access to the cases from Google for free.
EDIT: To be clear, I'm not intending to downplay or diminish the efforts of you and others to open up access to those older cases. I think that is great. All I am saying is that for the vast majority of people, the vast majority of the time, there really isn't a problem in finding cases online.
Opening up PACER really doesn't help in practice because the data is ridiculously dirty - crappy scanned PDFs which people then pay to have triple keyed.
With the entry of Google Scholar, the access and value-add businesses are divorced. The cost of the underlying access has reached zero. But the reason Westlaw and Lexis are still huge is because they do provide value-adds.
So this talk of opening up PACER is really missing the broader access point - the opinion access problem is largely solved via Google Scholar. PACER documents may be opened up, but they are not useful to lawyers in anything other than some basic docket scenarios.
