> After the U.S. attorney for the Southern District of New York declined to prosecute the case, Judge Kaplan took the rare step of appointing a private law firm, Seward & Kissel, to prosecute Mr. Donziger in the name of the U.S. government.

So the real problem here is people not reading the article, jumping to conclusions, and spreading misinformation in the comments (on HN?!). And probably the SDNY being too biased to enforce the law against a lawyer who cheated in a case against an oil company. Anyone who's been following the SDNY in the news for a while shouldn't be surprised about that.
