The modern over-expansion of QI actually started in 1982:
>The modern test for qualified immunity was established in Harlow v. Fitzgerald (1982).
Since then, while several justices (Kennedy, Scalia, Thomas, Sotomayor ) have sometimes dissented and criticized the over expansion of QI, the overall court doesn't seem to want to touch it.
