Every little bit of information that has been leaked about this case has been reproduced on a thousand websites. If a case had been presented there would be innumerable translations and commentaries - it would be easy to find. A cynic would say that the reason you're refusing to give the link is that you know it doesn't exist.
To respond to your specific comments:
The case had to be presented in order to get an extradition order. Yes, there is an extradition order which is why he can't leave the embassy.
I know that there was an extradition hearing (judgment text). However, as I explained before, the case did not have to be presented at that hearing, and was not presented at that hearing. The Court reviewed a very small amount of material to ensure that the formal requirements of the Framework Decision were met - that's all. If you're basing a conclusion about Assange's innocence or guilt on that judgment you're building a tower without any foundations.
There are absolutely allegations which have a case filed in courts. See above.
My use of the phrase "criminal case" was not an accident. My point is that there are no filings that form part of the process by which Assange's guilt or innocence are assessed. You refer me to the English extradition hearing, but that hearing did not (and could not) make any judgement about his guilt.
Swedish courts don't operate like the USSR, but you need to do enough translation to find the case. If you search Slashdot there have been links posted to translated documents in the past (over a year ago?).
I still can't find this case that's open for inspection. The Swedish prosecutor has a chronology which doesn't refer to any charges having been filed. Justice for Assange has a list of available documents that doesn't include any Swedish case, and states that "no charges have been filed". If you know of this publicly available case, post it! I would love to read it! But nobody else - including the prosecutor and campaigners - seems to have any idea that it exists.
If you want knowledge, go get it! A bit of research will go a long way. To translate and find year(s) old sources requires more energy than I'm willing to give up. I gave a few hints for how to search out the case which is sufficient to get you started. Your choice is to either gain knowledge or argue from ignorance. Hopefully you choose the former, but the later is unfortunately more common.
The reason that I ask you to post a link to the case that you refer to isn't that I'm lazy and want you to do the work - it's that I think that we are at cross purposes, and you are referring to something that I don't recognise as being a case that's sufficient to judge Assange's innocence or guilt. If you will just post the source that you're relying on we can get to the bottom of it quickly.
