Prompted by former President Trump’s spate of class actions against Facebook, Twitter, and Google, we recently shared some best practice tips on filing class actions, a topic close to our hearts. A new court filing and order in Mr. Trump’s case against Twitter offers us yet another opportunity to weigh in on a different and important subject to the Impact Fund’s mission—writing effective amicus briefs. So what have we learned? Write an amicus brief that actually says what you say it says. Write an amicus brief that is about an issue actually in the case. Don’t include six-page footnotes. Don’t suggest that the judge needs something explained at a fifth-grade level. Don’t tell the judge to issue an edict that the legislature pass a better law than the one on the books.
