Although the information is correct, the poster resoning is very silly. I am from Guadalajara, and I happen to know the guys on Alejandro Fernandez' Law Firm.
I assure you almost nobody here has ever heard from Jammie Thomas or Joel Tenenbaum, or care about it, and our law system for better or for worse is completely different from the US law system. The law is more based on the written law. It is very rare that a case creates precedent, and of course to a case from the US.
As much as I would love Sony Music get slapped with a big fine, you can expect they will only be slapped in the wrist and I almost sure that the lawswit aims more to prevent the distribution of the album and songs and scare some shit out of the stupid Sony execs.
Besides, Alejandro Fernandez is well known for being a very spoiled brat, so take his words with a big grain of salt. His lawyer is also very aggresive, so we can expect some media frenzy about this. But not much more.
