did you not read the part where they backdated the changes? So if you owe 5 cent in taxes and pay that and then a few years later the gov't says "we changed the code you owe us 50 cents and this retroactively applies to the last few years." You would be perfectly okay with that?
As a citizen, I would be perfectly ok with hiring a lawyers and tax accountant and disputing the charges using the existing system we have for disputing taxes and/or having unjust laws stricken off the books.
