On Friday, we filed our merits brief in Pearson v. Callahan, 07-751, a Fourth Amendment and qualified immunity case that the Supreme Court will be hearing this fall. I have posted a copy of the brief for interested readers: Brief for Petitioners, Pearson v. Callahan, 07-751. You can read Linda Greenhouse's story about the case for the New York Times here. You can also access the cert petition, brief in opposition, and cert-stage reply brief here.
