Federal appeals judge Richard Posner on Saturday returned fire in the latest round of his long-running dispute with U.S. Supreme Court Justice Antonin Scalia and Scalia’s co-author Bryan Garner.

Garner, a legal-writing expert, last week released a report he commissioned that examined a dozen allegations critical of Scalia in Posner’s 2013 book Reflections on Judging. Posner was critiquing Scalia and Garner’s 2012 book Reading Law: The Interpretation of Legal Texts.
