Following his 14-page hit Preparing Cert Petitions & Oppositions (2008), Dan Schweitzer, the director & chief counsel of NAAG's Center for Supreme Court Advocacy (for 20 years!) has posted online his 20-page U.S. Supreme Court Brief Writing Style Guide. (NAAG is the National Association of Attorneys General, sometimes called the National Association of Aspiring Governors.) Both works contain excellent advice. Thanks, Dan!
