Kozinski, who was named chief judge of the 9th Circuit last year, is considered a judicial conservative on most issues. He was appointed to the federal bench by then-President Ronald Reagan in 1985. He has a national reputation for a brilliant legal mind and has developed a reputation as a champion of the First Amendment right to freedom of speech and expression. Several year ago, for example, after learning that appeals court administrators had placed filters on computers that denied access to pornography and other materials, Kozinski led a successful effort to have the filters removed.
