Just stumbled on this humdinger of a qualified immunity case from 2019.

A Georgia man was exonerated by DNA after serving 7 years on a rape conviction. Because the Georgia had no compensation law for wrongful convictions, the state legislature . . .

. . . had to pass a special bill to compensate him. The DA who prosecuted him (the same DA who prosecuted Troy Davis, BTW) wrote a letter to the legislature claiming the man was still under indictment for rape and kidnapping. This was false to the point of libel. But it worked.

Because of the letter, the legislature killed the bill before it came to a vote. So the man sued the DA. In 2019 the 11th Circuit ruled: The DA lied, but he's still entitled to QI.

Why? Because there's no "clearly established law" stating that it's unconstitutional ...

... for a DA to lie to state legislators in order to prevent them from compensating an innocent man for the 7 years he spent in prison after he was wrongly convicted under the same DA.

As far as I can tell, the man (who was also stabbed while incarcerated) was never compensated.
